Is there a KiCad symbol and footprint for the EL814?
Yes. The symbol is Isolator:EL814 and the footprint Package_DIP:DIP-4_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 EL814?
DIP-4, with 4 pins. Its footprint is drawn on this page.
Where is the EL814 datasheet?
Everlight Electronics publishes it: the Datasheet link on this page opens it.
Where can I order the EL814?
JLCPCB lists it as part C71046, with 13,710 in stock; the sellers' links on this page open their listings.
What can replace the EL814?
Parts like it in the library: the K10101C by Cosmo Electronics, the ORPC-817C by Orient, the K10101B by Cosmo and the TLP621GB-1(UMW) by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the EL814?
25 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
