Is there a KiCad symbol and footprint for the 6N138?
Yes. The symbol is Isolator:6N138 and the footprint Package_DIP:DIP-8_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 6N138?
DIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the 6N138 datasheet?
Isocom Components publishes it: the Datasheet link on this page opens it.
Where can I order the 6N138?
JLCPCB lists it as part C255743, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 6N138?
Parts like it in the library: the TLP350(F) by Toshiba, the FOD3120 by onsemi, the TLP351(F) by Toshiba and the HCPL-3180-000E by Broadcom Limited. Check their datasheets: a part that fits the footprint may still differ in its ratings.
