content: Hello,I'm quite new about SMD parts and I'm looking for a codebook to help me identifying coded components.Sometimes is hard to understand what is what.Thissound scary to me"Unfortunately, each device code is not necessarily unique. For example a device coded 1A might be either a BC846A or a FMMT3904. Even the same manufacturer may use the same code for different devices!"is this true?Do you have any good online manual link to share?Many thanks in advance.

content: Um, wouldthisnot fit the bill?I've had luck just using Google. Just don't hesitate to use wildcards (xyza* returns anything starting with xyza, *xyza* yields anything containing it.), site: (e.g. site:alldatasheets.com) which yields results from a specific URL. I also like filetype: as in "filetype:pdf" as in "I don't want a supplier that can ship 30k units a day, just give me a freakin datasheet already!".Full list of Google search operators.Edit: BB Code formatting. Talk about not being a software guy.

content: Terrible huh? And the latest smt parts are so tiny they don't have any identification at all.

content: Wish manufacturers would micro-mark tiny components with a laser. Sure, you might need a microscope, but at least there would be something to go on.

content: Quote from: mcinque on November 23, 2013, 11:25:45 pmThat was my point. You linked to a database that translates SMD codes into chip names and descriptions, then asked for a database that translates SMD codes into chip names and descriptions. Are you just looking from something more comprehensive?

content: Ha, I didn't even notice how out of date it was. Keeping on top of something like that would have to be damn near impossible though. I might search around if I have some free time, hopefully there is a resource out there.

content: I appreciate your kindness but don't waste your free time for me: If a search is needed, I can do it on my own without boring you. My post was only if someone has something "ready to eat" to share.

content: That is a nice list Megatrommer, perhaps make a new post titled: "Sources for SMD codes" or something like that and ask an admin to make it a sticky post and let other users add to the list

content: What usually works for me is just Googling package type + marking, since those SMD marking sites have only older parts most of the time.(On the other hand, Google starts blocking you and serving you CAPTCHAs if you do this too much)
