Very true Glen.

Maybe a thread like this would be best off (as it is a sticky) to have a list of the parts at the top somewhere with cross references listed. Rather than searching post by post in a potentially lengthy thread.

Sorry, I searched the thread for opto and got nothing so I just replied, sorry!

How about a cross reference for the Opto-Isolator?.. Digikey is back ordered till at least June 7th.

I tried searching on Mouser and JameCo but couldn't find a close enough match to chance it on.
