No, I’m talking about the guy that builds prototypes out of his magic parts box and says “oh, you can still get those” when the last direct substitute was obsoleted in 2008. Or he’s using the old version of a part like this in a “proven” subcircuit and NOT checking for change notices or other the new data sheets. That’s what I mean by the “magic parts box”. Buy new parts for new prototypes and read all the latest data, folks.
