content: Ordering every replacement part for every plasma TV ever! Why didn't I think of that!Yeah it would be better to actually to email the list off to a rep especially if your ordering 2000 of each as you claim. But in reality people normally only want 1 of each in which case you will get much abuse in getting a rep or anyone here to help you.I suggest since you have the exact component specs which would include the brand, value, size, package, series, tolerance and temperature ratings of each component to start looking up part numbers and give them to a rep. I mean you can only go so far with DIO-SCHOTTKY as a description before your plan starts to falls apart.

content: Quote from: TopLoser on July 22, 2015, 08:29:02 pmSorry to the OP but I agree, I had no idea what line item 1 was, but I did about line item 2, 10nF 50V.My assembler has about half a million 10nF under my name unused because I'm too lazy to do an up to date stock check, but it's in 0402. (I usually buy the reels from Farnell, so you could prolly check how many 10nF I've bought Toploser!). As the OP didn't specify size or dielectric I fear this will indeed end in tears :-(To the OP: as an example, for a typical repeating BOM with about 120 line items, it takes me about half a day to a full day of my time in total to procure. This is about availability, pricing, finding appropriate substitutes for out of stock or discontinued items, and finally lead times across several distributors and manufacturers.There are few short cuts other than experience and graft. The first time for a BOM of about this size takes me at least twice as long.

content: You're not going to get very far with this list, take for instance:IC 32-BIT MPU 760MIPS AT 400MHZ 272-BGAwithout a manufacturer and specific type this is insane.I am afraid that only firms that want your money and scam you will respond to such a generic part list.

content: Sorry everyone, I did not realize how bad the descriptions are.I have a detailed spreadsheet but was not sure it was worth anyone's time unless they are a dealer and all ready have inventory.May I did not make it clear but I'm very willing to share that will someone that's really willing to take a shot at this.In the larger scheme it's a small order but could lead to larger business.So when you see something like this:RESISTOR 68.1 +-1pct .063W TKF TC=0+-200That might be tied to my internal part number 3220 which means nothing to you of course.But I would also have this flow out underneath on the spreadsheet.MCR03EZPFX68R1 ROHMMC0603-68R1-FT201W RCD COMPONENTSRK73H1JTTD68R1F KOACRCW060368R1FKEA VISHAYRC0603FR-0768R1L YAGEOAny of the above are acceptable manufactures for the description/part number.And I need let's say 200 each, not a lot I know.What I don't know is the accuracy of the OEM part numbers, most appear to be good. Yet I could not fine the ones above.For another part...CR16-1001FL ASJCRCW06031K00FKEA VISHAYMCR03EZPFX1001 ROHMRK73H1JTTD1001F KOAMC0603-1001-FTW RCD COMPONENTSRC0603FR-071KL YAGEOI did find these.If this is not a good fit for the community sorry, was just trying to let a dealer that post here make a buck.Either way I have to provide a quote to a customer and if I go back with Digikey pricing I'll still likely get the prototype order but not the production orders. Not that it's a big deal to me I'm on salary so either way my bottom line is the same.I did have some luck buying a multimeter for personal use here and a few others things.I'm just learning really but it happen my day job sort of overlapped with my new hobby and thought I'd try to pass along and opportunity. Sorry if it created stress.. like I said if it's not a fit.. for anyone that's cool. If it is PM me and I'll send you a spreadsheet.

content: QuoteI would roll up your sleeves and get ready to spend a couple of days checking availabilty, pricing, possible substitutions and lead times across a range of suppliers. I'm afraid it really does sound like you're too lazy to do the procurement for yourself I'm afraid: grow a pair, open up a few browser windows and a spreadsheet, and knuckle down for a couple of days. It isn't hard, but it is time consuming grunt work, and it will often take a couple of iterations to get right, for example when suppliers turn out not to hold the stock they say they do.If pricing is so important to you, then the best way to guarantee the best pricing is to do it yourself, in my experience it's always cheaper than getting a distributor or third party to do it for you. But be careful, some assemblers won't take free issue parts because they make money from their procurement "added value"...If I may add, if you ask someone to quote for "50, 200 or several thousand" you'll almost certainly end up in the tyre kicker tray. Even if you don't, doing a quote for 50, 200 or 5,000 is almost the same as asking someone to domthe same job three times. There is going to be diferent availabilty and pricing points across multiple suppliers. Be honest to yourself, how many are you going to make on your first run and stick to that. Anything more is a bonus, and a bridge to cross when you get there.

content: Quote from: Simon on July 24, 2015, 06:01:03 amThey will need a decent BOM to go off though. You also need to be very careful of _any_ substitutions. In addition, the discounts they say they offer, if you get any, will not be better than hand selecting from multiple suppliers, and neither will it deal with a parts shortage.Edit: I have never had any luck with assemblers being able to better my own free issue pricing.Caveat emptor!

content: Subcontractors or at least the one I deal with want the manufacturers part number or the farnell number. He will not shoose your part based on a spec, he wants to know the part number, his first choice is farnell but he will deal with anyone who has what you want.the point is any of the major distributors will give better prices to customers buying large volumes of the same part or making large orders with them. RS openly advertise that is your order is over £500 they will give you discounts, the same goes for farnell.Now i could go buy all the parts I need for a project from farnell and where we are talking resistors and capacitors any distributor is the same, but if i tell the assembler which farnell parts are on the bom he can get them with a discount because he is spending thousands of pounds per month with them, simple as.
