Is there a KiCad symbol and footprint for the 2SA940?
Yes. The symbol is EasyEDA_Cloud:TIP125_C2907702 and the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 2SA940?
TO-220C, with 3 pins. Its footprint is drawn on this page.
Where is the 2SA940 datasheet?
ISC publishes it: the Datasheet link on this page opens it.
Where can I order the 2SA940?
JLCPCB lists it as part C491404, with 0 in stock; the sellers' links on this page open their listings.
What can replace the 2SA940?
Parts like it in the library: the BU406 by SPTECH, the TIP32C by onsemi, the 2SC2073 by JSMSEMI and the D45VH10 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
