Is there a KiCad symbol and footprint for the BF420?
Yes. the footprint Package_TO_SOT_THT:TO-92L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BF420?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the BF420 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the BF420?
JLCPCB lists it as part C19269005, with 781 in stock; the sellers' links on this page open their listings.
What can replace the BF420?
Parts like it in the library: the SS8050D331 by ALJ, the SS8550D331 by ALJ, the BF420-TA(RANGE:MIN=50) by Jiangsu Changjing Electronics Technology (CJ) and the SS8050 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BF420?
2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
