Is there a KiCad symbol and footprint for the MOC3043M?
Yes. The symbol is Relay_SolidState:MOC3043M and the footprint Package_DIP:DIP-6_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MOC3043M?
DIP-6, with 6 pins. Its footprint is drawn on this page.
Where is the MOC3043M datasheet?
AOTE publishes it: the Datasheet link on this page opens it.
Where can I order the MOC3043M?
JLCPCB lists it as part C20624245, with 2,727 in stock; the sellers' links on this page open their listings.
What can replace the MOC3043M?
Parts like it in the library: the EL3053 by Everlight Electronics, the MOC3052 by Lite-On, the MOC3053M(UMW) by UMW and the MOC3081M(UMW) by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the MOC3043M?
9 boards in 8 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
