Part is discontinued, what is everyone using now?

512-H11AA1 is not available to purchase. This is the ZC Opto.... Just want to make sure I order the right part

Brad,
It looks like the 512-H11AA1-M would be a good replacement. The only difference I can see is the IF, 60ma vs 100ma. I would wait for confirmation from Phil 1st.

At a quick glance that part looks fine. The current through the input diodes of that part in the Renard16 design is around 5.6 mA if you use the recommended resistor values, so there is still a huge amount of margin.
