Questions

Is there a KiCad symbol and footprint for the BU941?

Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2E_3C_4C and the footprint EasyEDA_Cloud:TO-3_L39.4-W26.7-P10.92-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BU941?

TO-3, with 4 pins. Its footprint is drawn on this page.

Where is the BU941 datasheet?

SPTECH publishes it: the Datasheet link on this page opens it.

Where can I order the BU941?

JLCPCB lists it as part C2907936, with 3 in stock; the sellers' links on this page open their listings.

What can replace the BU941?

Parts like it in the library: the MJ15015 by onsemi, the 2N5686 by SPTECH, the MJ21194 by SPTECH and the 2N4399 by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
