Is there a KiCad symbol and footprint for the RPI-221A?
Yes. The symbol is EasyEDA_Cloud:RPI-222N1 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 RPI-221A?
DIP-4, with 4 pins. Its footprint is drawn on this page.
Where is the RPI-221A datasheet?
ROHM Semiconductor publishes it: the Datasheet link on this page opens it.
Where can I order the RPI-221A?
JLCPCB lists it as part C509287, with 998 in stock; the sellers' links on this page open their listings.
What can replace the RPI-221A?
Parts like it in the library: the RPI-352 by ROHM Semiconductor, the ITR9606-F by Everlight Electronics, the ITR8104 by Everlight Electronics and the RPI-222 by ROHM Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
