Is there a KiCad symbol and footprint for the HCPL2731?
Yes. The symbol is Isolator:HCPL2731 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 HCPL2731?
PDIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the HCPL2731 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the HCPL2731?
JLCPCB lists it as part C899537, with 0 in stock; the sellers' links on this page open their listings.
What can replace the HCPL2731?
Parts like it in the library: the ACPL-T350-000E by Broadcom Limited, the HCPL-2731-000E by Broadcom Limited, the 6N139-000E by Broadcom Limited and the HCPL-4701-000E by Broadcom Limited. Check their datasheets: a part that fits the footprint may still differ in its ratings.
