Overview
The TIP121TU is a bipolar Transistors, BJT made by onsemi in a TO-220 package with 3 pins. -65℃~+150℃ 1000 2.5V 200uA 2W 4V 5A 5V 80V NPN TO-220 Darlington Transistors ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:TIP121, 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 C900049).

Questions
Is there a KiCad symbol and footprint for the TIP121TU?
Yes. The symbol is Transistor_BJT:TIP121 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 TIP121TU?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the TIP121TU datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the TIP121TU?
JLCPCB lists it as part C900049, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TIP121TU?
Parts like it in the library: the TIP41CA by FeiHong, the TIP42CB by FeiHong, the TIP120TU by onsemi and the TIP41 by TF. Check their datasheets: a part that fits the footprint may still differ in its ratings.
