Yes, searching for what's in stock at a decent price, not what might've been manufactured to suit the task. Quite different, and why one is stuck with suppliers' web sites. The free delivery option for web orders here is an incentive too ;) Grant. > >Regards, > >Joerg

I often must peruse the selection, see what's there, high in Have you ever tried? You don't need a part number to search for e.g. "0.1uF Polypropylene Capacitor." That works on both findchips and octopart. And they show you what's in the inventory of major distributors. Including DigiKey :) > stock, low in price.

That is much better done with findchips/octopart. And not bound to a single boutique. BTW, if DigiKey has something in stock at the moment has almost no correlation with production quantities availability. The reverse is also true. You can not get everything from a single place. Just one example--I recently tried to buy several thousands of BC550/60C transistors. The funny thing was Avnet had BC560CTA @ $0.0163 each but no BC550C at all. I bought 2 ammopacks of 2,000 for $65 from them (that was all they had in stock.) On the other hand Arrow only had (and still have) BC550CTA at the same price but no BC560C at all. That was a couple of days ago. Now Avnet has 32K of BC550CTA in stock. If you were shopping at Avnet only a week ago you would've said that BC550C are unobtanium because they do not have them in stock while both findchips and octopart kept telling Arrow has plenty in stock. --- ****************************************************************** * KSI(a)home KOI8 Net < > The impossible we do immediately. * * Las Vegas NV, USA < > Miracles require 24-hour notice. * ******************************************************************

Zero, nada, zilch. If DigiKey doesn't stock anything it absolutely doesn't mean it is not available from others. And the opposite is also true--if they have some obscure part in stock it doesn't mean somebody still manufacture that part and it is available from somewhere else. And one more thing--parts availability is constantly changing these days. Sometimes the entire quite sizable stock gets purchased buy somebody else literally from under your hands. Yesterday I put a box of polystyrene capacitors in my cart on Mouser and kept shopping for something like 10 minutes. When I returned to the cart to checkout they all gone; somebody bought their entire stock and now that particular part is on backorder. --- ****************************************************************** * KSI(a)home KOI8 Net < > The impossible we do immediately. * * Las Vegas NV, USA < > Miracles require 24-hour notice. * ******************************************************************

Even when I need a datasheet, I have a habit of searching up the device in the DigiKey web pages and then following the datasheet link. I find it much faster than navigating through eg. TI's or Analog's selection trees or using *their* search facilities. When passing through DigiKey pages it's also easy to drop an order when there. Ordering from US seems to be no problem in nowadays globalized economy. Farnell has an edge by delivering overnight, whereas DigiKey and Mouser take a few days. When ordering on Friday there is not even that difference - the world logistics machinery keeps grinding on weekends. The only complication with DigiKey and Mouser orders is that every now and then you get some ITAR related end use clarification requests, whose replies set back the delivery by a few days. Farnell sortiment and their web engine are OK, although the web engine is SLOW. Many other distributors' (RS, Future...) look and feel I don't like - I find them messy and counterintuitive.

Logic isn't your strong suit, is it? It tells me that it *is* available, somewhere; tautology. If it's available in one place chances are it's also available elsewhere, but it *is* available (i.e. a real part). Sure, the inverse isn't necessarily true but so what? I don't design by logical fallacy. > And one more thing--parts availability is constantly changing these days. > Sometimes the entire quite sizable stock gets purchased buy somebody else > literally from under your hands.

My intention is to make sure I'm not designing in any maximware. That's particularly important these days. The chances are next to zero that we'll buy production parts from Digikey anyway. Their prices are out of sight. The next step would be to get price/delivery quotes from my normal sources (generally Arrow, Avnet, or Future). Checking first at DigiKey shortens this process immensely. |
