Questions

Is there a KiCad symbol and footprint for the BD439?

Yes. The symbol is Transistor_BJT:BD439 and the footprint Package_TO_SOT_THT:TO-126-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BD439?

TO-126, with 3 pins. Its footprint is drawn on this page.

Where is the BD439 datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the BD439?

JLCPCB lists it as part C3031921, with 245 in stock; the sellers' links on this page open their listings.

What can replace the BD439?

Parts like it in the library: the BD136 by DDF, the 2SB631 by ISC, the 2SD600 by ISC and the BD235 by ISC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
