Questions

Is there a KiCad symbol and footprint for the BD438?

Yes. The symbol is Transistor_BJT:BD438 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 BD438?

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

Where is the BD438 datasheet?

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

Where can I order the BD438?

JLCPCB lists it as part C2910302, with 200 in stock; the sellers' links on this page open their listings.

What can replace the BD438?

Parts like it in the library: the BD434 by LGE, the BD441 by onsemi, the BD438 by STMicroelectronics and the BD437 by YFW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
