Is there a KiCad symbol and footprint for the BF122M?
Yes. The symbol is EasyEDA_Cloud:BK12013502-P and the footprint EasyEDA_Cloud:DIO-DT-SMD_L4.2-W5.0, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BF122M?
SMD, with 2 pins. Its footprint is drawn on this page.
Where is the BF122M datasheet?
Bencent publishes it: the Datasheet link on this page opens it.
Where can I order the BF122M?
JLCPCB lists it as part C5337221, with 5 in stock; the sellers' links on this page open their listings.
What can replace the BF122M?
Parts like it in the library: the 2035-09-SM-RPLF by Bourns, the X5-150XSMDT by SURGING, the BF471M by Bencent and the SC2E5-90LSMD by SOCAY Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
