Is there a KiCad symbol and footprint for the IL221AT?
Yes. The symbol is Optocouplers:Optocoupler Type28 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the IL221AT?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the IL221AT datasheet?
Vishay Intertechnology publishes it: the Datasheet link on this page opens it.
Where can I order the IL221AT?
JLCPCB lists it as part C17490256, with 0 in stock; the sellers' links on this page open their listings.
What can replace the IL221AT?
Parts like it in the library: the MOCD213R2M by onsemi, the HCPL-0701-500E by Broadcom Limited, the MOC207R2M by onsemi and the HCPL-073A-500E by Broadcom Limited. Check their datasheets: a part that fits the footprint may still differ in its ratings.
