Overview
The 2SA1941 is a bipolar made by Minos in a TO-3PS package with 3 pins.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:TIP125_C2907702, from EasyEDA) and its footprint (EasyEDA_Cloud:TO-3PL_L20.0-W5.0-P5.45-L, from EasyEDA), ready for a KiCad board. 54 are in stock at JLCPCB (part C6719382). 1 open-source board in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the 2SA1941?
Yes. The symbol is EasyEDA_Cloud:TIP125_C2907702 and the footprint EasyEDA_Cloud:TO-3PL_L20.0-W5.0-P5.45-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 2SA1941?
TO-3PS, with 3 pins. Its footprint is drawn on this page.
Where is the 2SA1941 datasheet?
Minos publishes it: the Datasheet link on this page opens it.
Where can I order the 2SA1941?
JLCPCB lists it as part C6719382, with 54 in stock; the sellers' links on this page open their listings.
What can replace the 2SA1941?
Parts like it in the library: the NJW0302 by onsemi, the 2SA1943 by Minos, the 2SC5200 by Minos and the TTC5200 by Minos. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the 2SA1941?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
