D405: use Nexperia part sourced from Digi-Key direct The previously selected part was from a Digi-Key marketplace vendor, and they seem to not actually have that part, as the order has been in limbo for over a month - so I put in the time and effort to look around, and found a readily available equivalent part from Nexperia.
