Yup, first thing I do is match all components on JLC's inventory for a given footprint and input price, JLC part # and Manufacturer part # in my symbol editor (Kicad), as well as if it's a Basic part or Extended part. My design depends on availability at JLCPCB, that's why I select PICs that are currently available.

I'm not looking forward to the day I have to start looking for compatible PICs because they are out of stock. New IC prices are just insane, even if we get to stock direct from Malaysia.
