I just ordered 20 42TL004’s from here. They’re currently 1.75x more per unit than Mouser, and shipping seems to be a flat rate of $20ish, so they’re not cheap, but if you’re desperate, this could work. Assuming I get my order in a timely fashion and these work out, I may be up for reshipping within the US at cost.
I’m in! THanks for the help.
