My biggest issue is in finding an understandable cross-reference. My Mickey Mouse Radio Shack Learning Lab came with transistors simply marked C9014. I can find data sheets easy enough but when I try to find a place to order them they offer NPNs with numbers other than that (but not the 9014). So I need some way of knowing what will interchange. Thanks

content: Quote from: easilyconfused on July 29, 2010, 06:12:37 amThere are so many transistors out there it's nearly impossible to cross reference them. You sort of just have to dive into the datasheets and get close, looking for the special bits that are unusual. If you're not doing anything particularly special then almost anything that's the same polarity (PNP vs. NPN) and size (TO92 in this case) should work ok.Here's a good writeup on selecting a replacement transistor.Hope that helps some.

content: For me the best place to look for datasheets for jelly-bean components - ishttp://www.datasheetcatalog.com/Not google, because in datasheetcatalog you can select datasheets from different manufacturers for a given component.Usually when searching for components I use two websites:http://DigiKey.com/andhttp://www.datasheetcatalog.com/(o, well, and google of course)But I wanted to tell you about one thing that _really_ speeds up searching for datasheets.It's a small browser tweak I use - search engines keywords.For example: If I want to look for BC817 datasheet, I just type "d BC817" (without "", of course) in my browser address bar. And momentarily I'm getting list of datasheets from different manufacturers for BC817 from datasheetcatalog.The same way I can search for videos on youtube typing: "y SomeVideoNameToLookFor" or on wikipedia "w nuclear reaction", etc.To add DatasheetCatalog to the list of search engines I've used "Add To Search Bar 2.0" firefox addon (which you can find in list of official addons).I've included some screenshots - they're pretty much self-explaining.

content: What's wrong simply grabbing them from the manufacturers website ? All those cyber-squatter sites like all-datasheet and others do nothing else but make you jump through hoops to get a pdf file. And very frequently they present you the wrong one. I have a lot of instances where you land on these sites and the datasheet isn't even there.Another problem is that they often have old versions of the datasheet with outdate information or mistakes.my advice : ALWAYS go to the manufacturers site FIRST. if you don't know the manufacturer : go to Digikey or Mouser websites and type in the partnumber. you will get a list of parts: 99.9 % of the parts these guys sell has the link to the REAL datasheet from the manufacturer. Simply click on the icon there and you will have the latest version.If it's an obsolete part THEN, and only THEN can you use those garbage collectors, and spewers, like alldatasheet, chipfind. There's even an outfit that sells you a subscription to their datasheet collection. These guess essentially sell you PDF files that they do not own , or are licenced to sell. ( yes the datasheets do carry a copyright by their writers and companies that own them)Google relly needs to make work of eliminating all those datasheet squatter sites.

content: Note that only the main datasheet for a part cannot be enough.Most (digital) parts have errata sheets, that require careful reading if you don't want to get stuck for DAYS at an odd problem. And you do want to have the most recent version, claiming (hopefully) all the bugs for each silicon revision.Some CPU datasheets have separate user manuals, summary datasheets, or microchip even list each peripheral in it's own document. For a PIC32 there are like 24+ PDF's on 1 chip's page , all with useful information.Then there are application notes, sample schematics/projects and/or evaluation boards that can be useful for designing as well. These are neither found on these generic websites.Chances are you won't find these very useful documents easily (or at all) on alldatasheet.com or a like.@Simon: User manuals or datasheets from NXP/ST ARM microcontroller parts can be a rollercoaster-ride-with-the-scrolling-wheel as well..

Just ads and spam.Try a Google for the part and see what results you get. Look for direct PDF links from the reputable semiconductor companies, or try their websites directly if you can identify the device manufacturer.Or try a distributor like Digikey. Look up the part and the product page will give you a no-fuss datasheet direct link.

content: Just wanted to pitch in here as the person that keeps all the documentation on our website up to date. We only keep our own site up to date - we do not have agreements with any of these other sites mentioned to feed them with the latest version of any drawing. As for distributors, we feed our authorised distributors a list of links so they can link direct - if they are taking their own copy we can't guarantee it's up-to-date I'm afraid.As an engineer I also would go straight to the manufacturer first whenever possible, for the same reasons. However, I do realise that not as many older or obsolete drawings are kept on manufacturer websites, and these sites may be useful for these documents. Other manufacturers may also have larger teams that can ensure documentation is kept updated at other sources.

content: Quote from: 74HC04 on October 15, 2009, 10:09:38 pmI am fairly new to finding out what part I have. I like salvaging items from boards.For example I have a part that has d2396 on one line. On a lower line are a J and a strange T 08 and at the top it looks like an R.When I did a search for d2396 I got d2396 from Bristol Electronics and I also found a 2SD2396K from Digikey.Can you tell who made the chip?Is there any consistency on the markings?P.S. I saw a video with a guy reviewing a electric vacumn desoldering gun. It made short work of removing chips, etc.

content: If you can't find the datasheet, you might be able to find the databook here at Internet archive. There are many manufacturers, quite a few years including some from the 60's.archive.orgOr just google Internet Archive.I downloaded a bunch of databooks. Motorola, texas Instruments, Philips, Toshiba, Hitachi, Sony, Panasonic, etc., etc., etc.If you use a tablet, download them to a large USB stick or memory card.

content: Doesn't look like it's been mentioned so far - I personally reccomendwww.manualslib.com. I frequently find manuals I need for work on there, and the layout is reasonably ok.Quote from: Lost resistor on April 03, 2021, 02:27:51 pmNot unusual at all. They're not obligated to be helpful, but most big companies will try and help find what you're looking for (then try and sell you stuff).

content: As a novice I like the old data sheets from the likes of ON Semiconductor and Texas Instruments. They have the usual data but then they go further into example circuits which I find very handy. The newer data sheets don't have this so much.

content: I am noticing that a lot of the spammy web sites are creating phony PDFs to take advantage of those of us who search for datasheets using Google's "filetype:pdf" advanced search parameter. One way which I now use to defeat these spammers is by adding "absolute maximum" (in quotes) to the search criteria. I find that this phrase is almost universally present in electronic component datasheets.Also, if you wish to restrict your search to a particular site, use something like "site:ti.com" as a search parameter.

content: It is shortcut from "TEchnika SLAboprouda" freely translated as low current technology. The parts are common on east Europe markets (communist block). More details inwikipedia. I'm not sure if there is something what make sense to mention, since they have produced a lot of copies of western parts and can be directly exchanged with originals. Some have unique name, but for example logic ICs used same numbering.

content: Hi Guys,I was literally going to create a new post and then i came across this database related thread and thought .."Perfect".Let me explain what was happening,Short Explanation : I'm Posting a RELIABLE E.S.R. ListGranted Beginners won't understand, so.. here's the explanation before the list.SUBJECT : GAINING RELIABLE E.S.R. VALUES TO KNOW IF A CAPACITOR IS GOOD OR BADHISTORY : I'm 50 years old, I have used this list for at least the last 40 years and i have not had to update it in the last 10 years at least.Let me explain FOR THE NEWBIESWhen Measuring capacitors when fixing stuff,You want to know the capacitor works.so...- You may crack out a continuity tester (This is a very poor way of testing a capacitor)- You may crack out a Digital Multimeter in Capacitance Mode and do it that way (Also not very good, and doesn't work in Circuit)- You may even buy an ESR Meter or component tester and it has a very tiny ESR list on it, or someone may have told you that"Just keep it under 0.2 Ohms and you'll be right" well that's not correct either and the list you get with the ESR tester is not a very goodlistYou're going to quickly learn1. You need to test the caps reliablyso that you don't install a shit capacitor in a unit thinking it was good and fixed becausethis will cost you time and money2. You need to know what value to expectNO MATTER WHAT THE CAPACITOR VALUE ISNow yes you can download the datasheet, but- You need to get the Exact Brand- The Exact capacitance value- The Exact voltage rating- Th Exact Tolerance Rating- The Exact Physical sizeBecause all of these things can vary the E.S.R. of a capacitor.NOW HERE IS WHERE I SAVE YOU DECADES OF HEADACHES AND RESEARCHOnce upon a time i was confused as hell and i said this to myself ..1. Given that different brands of same cap values can have Different E.S.R. Readings. How do we unify this a bit better so we don't have to store thousands of readings for 1 capacitor value ?2. Do i need to have a list for EVERY SINGLE CAPACITOR VALUE OUT THERE ?ANSWERSAnswer 2 First.. No you don't need to have in your list Every single cap value, You just need to have EVERY VALUE for the one's that you commonly use in your common applications and fixes.you will come to understand that fixing monitors are going to have certain common cap values, then.. fixing Laptops are going have different ones, Fixing audio amplifiers are going todifferent one's again. Let your electronics journey organically dictate which it is.Answer 1 - Ok, so what you do is this (i have already done this) so let me explain it.Let's say that we have 680uF capacitor , 100V RatedLets say the manufacturer datasheet says that the ESR should be 0.3 OhmsOK, well all we need to know is.WHAT VALUES ARE WE GOING TO ACCEPT IN OUR WORKBecause this is all that is importantIn my list for this capacitor i have the following values 0.07 0.13 0.18LET ME EXPLAIN HOW THIS WORKSthe lowest figure is THE LOWEST MEASUREMENT I HAVE EVER TAKEN ON ANY CAPACITOR IN MY LIFE FOR THAT VALUEthe highest figure is THE UPPER LIMIT THAT I WILL ACCEPT AND WON'T GO BEYOND and that i feel confident withThe Middle figure is the average of ALL CAPACITORS EVER TESTED IN MY LIFE FOR THAT VALUEso here is how this list was created.1. you need to have some high E.S.R. values and blow shit up to know "Ohh right, so i can't go that high" LOL2. if you remove say 10 capacitors from a board, Chances are they are not all going to be bad. What you do is.. Measure the ESR of all them and make sure they are pretty close to each otherin value of ESR (This is a good starting point).AS A PERSONAL DECISION (and you are free to change the spreadsheet in anyway that you wish)1. I didn't like using 0.0 as a minimum because, it goes without saying that that's a good value, I NEEDED REAL VALUES2. I needed to know the Max that WOULD ABSOLUTELY GUARANTEE A FIX and that i didn't have to worry about it.3. The Middle is the AVERAGE (Total number of capacitors tested and their total values added up divided by the number of capacitors tested.Now when you get a new batch of say 20 but you have a mid reading of 0.13 you do the calculation based on 21 capacitors and the first one had an ESR of 0.13 this way , You are including every single capacitor that you have ever included in your listLASTLY... THIS LIST GETS UPDATED LITERALLY EVERYTIME I USE OR TEST A NEW CAPACITOR thus over time it gets checked for accuracyNow, all the values i have in this list ARE ALL THE VALUES I HAVE NEEDED TO USE IN 50 YEARS and all the ESR values are the ESR values that have always guaranteed me a fixif you get to a point where YOU CHOOSE you want to increase the max value.......... THAT'S FINE, Just test it that it does work on the product safely. In some cases i do concede that the max value could be much higher according to the manufacturer datasheet, it's just that i have never tested a cap that high, and thus never had the need to increase the max value.so with that being said and now you understand how the list came aboutHERE IS THE LIST IN TEXT FORMATAND I HAVE ATTACHED A SPREADSHEETVERSION OF IT AS WELL, Feel free to use it anyway you like. I literally had to organise all my caps recently, I have 10,s of thousands of them, but only these values. so i figured i would share the list with the communityFOR BEGINNERS THIS IS AN INVALUABLE

Enter the value in the correct position2. test the capacitor you haveBut the obviousness of the problem is... HOW DO YOU KNOW WHAT THE CORRECT VALUE IS ?Answer : Look at the ESR value of the caps above and below it as there is direct correlation when increasing or decreasing in valuebetween capacitance and voltage. so just gets the values of the caps above and below, after that, when you get more of that valuecap you can test them against the value you currently have an update itLastly you can go to one of the suppliers and get the datasheet and look up the ESR value if available
