How does this design strategy actually avoid supply problems, e.g. when a component manufacturer issues EOL notice, what stops professional logistics/procurement staff at Big Fish Corp--whose design activities were likely responsible for the supply glut to begin with--from pushing lifetime buys to ensure sustainment of their product line, instantly draining global authorized distributor stock overnight?
- crispyambulance 8y agoyes, EOL's and ECN's pop-up a lot. Sometimes it's nothing (a pin-compatible alternative exists), sometimes it's a nightmare requiring a design change. At my work, we have seats with SiliconExpert, this is a tool that you can use to get availability "risk assessments" for your BOM among other things like RoHS stuff and conflict minerals status. I've never seen an "overnight global supply draining" occur for a part. There are distributors that make a living buying up millions of components throughout their lifecycle and then sell them for ~20X their cost (or higher) when the part goes EOL. It might be annoying, but these vendors can keep you going until a suitable replacement is located, designed-in, qualified and rolled out to production.
