Overview
The BD441 is a bipolar made by YFW in a TO-126 package with 3 pins.
PCBKit's library has its KiCad symbol (Transistor_BJT:BD441, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-126-3_Vertical, from KiCad's library), ready for a KiCad board. 102 are in stock at JLCPCB (part C22391924).

Questions
Is there a KiCad symbol and footprint for the BD441?
Yes. The symbol is Transistor_BJT:BD441 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 BD441?
TO-126, with 3 pins. Its footprint is drawn on this page.
Where is the BD441 datasheet?
YFW publishes it: the Datasheet link on this page opens it.
Where can I order the BD441?
JLCPCB lists it as part C22391924, with 102 in stock; the sellers' links on this page open their listings.
What can replace the BD441?
Parts like it in the library: the BD441 by onsemi, the BD438 by STMicroelectronics, the BD437 by YFW and the BD438 by YFW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
