Is it just me or is the pricing at Digikey getting ridiculous?

True, which is why I wanted a good in-circuit test to alert us if something goes wrong down the line. In this case, it's either the wire is right or it's not. If they switched wire on a batch it could be ugly. Unfortunately, we can only catch 2/3s of the failures but at least that's a good sampling plan. ;-)

Check "SHIP ORDERS COMPLETE" and that wont happen.That happened to me once before I realized about the "SHIP ORDERS COMPLETE" I called their free number and they took the charge off. > Which is not much of a problem to the few doing electronic >circuit/product production in USA, and a minor extra cost to those doing >product development work. > > Hobbyists appear to me to be something that Digi-Key caters to somewhat, >especially in the times of Rat Shack doing many things that repelled >hobbyists. In fairness the wide price discrepancy on PIC's between Digikey and Newark isnt as wide as it used to be. I havent compared in a while but I just did and Digkey is maybe 20-30% higher versus the last time I checked in which they were typically 2 times the price for the same PIC's. > I also seem-to-think that Digi-Key has a bit of liking to electronics >repair types, as well as for product development types.

We also have a college and two universities that have EET and EE programs ( one of the Universities) so you would think places like the source would stock decent components but they dont. I went into the source asked for a PCB blank and the guy gave me a blank look. He didnt have a clue what I was talking about. I bought a decent soldering iron there I went back about a month later looking for a replacement tip and they didnt stock one and didnt know where to get them. They now carry replacement tips for their current soldering irons so sometimes complaining does work.;-)

IIRC, Digikey's pricing for PICs is quite competitive at 25+ quantity. Maybe not so much at 1pc or 1000+ pcs. Eg. PIC18F13K22-I/P 25+ Digikey US site: 1.99 USD Digikey CAD site: 2.25 CAD = 2.20 USD Mouser US site: 1.99 USD Mousr CAD site: 2.25 CAD = 2.20 USD Microchip 1.99 USD Newark 1.99 USD Avnet 2.19 USD

Newark 2.34 CT singles $2.21 100+ quantities http://canada.newark.com/microchip/pic16f887-i-p/8-bit-microcontroller-ic/dp/27M9657 Digikey same PIC Canadian site $3.17 CT 2.35 100+QUANTITY http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=PIC16F887-I/P-ND That's the typical spread I'm seeing on PIC's I use. It has improved significantly since the last time I did a direct comparison there would typically be a 2x spread on CT, and a much wider spread in quantities. The same for transistors (BJT'S FET). When I was comparing FETS with Newark; Digikey's T/R price was the same as Newark's CT price. I don't know about you but I'm not buying T/R's (2500+) of transistors so that price is irrelevant to me. Why anyone would buy production quantities off a distributor still boggles my mind. A single FET example. This is a good jellybean FET neither currently has stock but Newark will soon. When Newark originally got these they were less then a quarter CT now they are 0.35 cents but they couldn't keep enough of them in stock 2500 one day 200 the next etc.. http://canada.newark.com/stmicroelectronics/stn3nf06l/mosfet/dp/89K1566?whydiditmatch=rel_1&matchedProduct=STN3NF06L Digikey http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=497-3177-1-ND Ones that both have in stock http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=SI2308BDS-T1-GE3CT-ND Newark http://canada.newark.com/vishay-siliconix/si2308bds-t1-ge3/transistor/dp/16P3708 They still have some work to do on Transistors, for me anyway. Before Digikey fans jump on me I know that there are some cheaper ones at Digikey then Newark, but for me Newark is always cheaper.

Everything I need for electronics arrives by courir. I rarely go to electronic shops for parts because they seldom have parts I need. If a shop has all the parts you need, you're probably not building something special. |
