Overview
The TIP41 is a bipolar Transistors BJT made by TF in a TO-220 package with 3 pins. TO-220 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:TIP41, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-220-3_Vertical, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C845395). 36 open-source boards in 32 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the TIP41?
Yes. The symbol is Transistor_BJT:TIP41 and the footprint Package_TO_SOT_THT:TO-220-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TIP41?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the TIP41 datasheet?
TF publishes it: the Datasheet link on this page opens it.
Where can I order the TIP41?
JLCPCB lists it as part C845395, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TIP41?
Parts like it in the library: the TIP41CA by FeiHong and the TIP42CB by FeiHong. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the TIP41?
36 boards in 32 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
