Building new designs with new-stock parts that are ancient transistor and diode implementations, a Standard Part list has emerged. This list is reflective of 2021-era component cost, the new semiconductor shortages, final status EOL, availability compromises, and the performance corners necessary. And some unavailable parts (in that I have sufficient stock from 2001, or later) may still get a role for certain niches, until I can devise an adequate replacement that is available. Generally, most parts are available, sometimes from multiple vendors. Following the Standard Semiconductor Parts List is an Alternatives/Special Functions List.
