Is there a KiCad symbol and footprint for the ICPL2531?
Yes. The symbol is EasyEDA_Cloud:CYHCPL2631 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 ICPL2531?
DIP-8, with 8 pins. Its footprint is drawn on this page.
Where is the ICPL2531 datasheet?
Isocom Components publishes it: the Datasheet link on this page opens it.
Where can I order the ICPL2531?
JLCPCB lists it as part C255756, with 27 in stock; the sellers' links on this page open their listings.
What can replace the ICPL2531?
Parts like it in the library: the HCPL-3760-500E by Broadcom Limited, the HCPL4503M by onsemi, the HCPL2530 by onsemi and the HCPL-2231-300E by Broadcom Limited. Check their datasheets: a part that fits the footprint may still differ in its ratings.
