Questions

Is there a KiCad symbol and footprint for the TIP122?

Yes. The symbol is Transistor_BJT:TIP122 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 TIP122?

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

Where is the TIP122 datasheet?

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

Where can I order the TIP122?

JLCPCB lists it as part C5350028, with 1,120 in stock; the sellers' links on this page open their listings.

What can replace the TIP122?

Parts like it in the library: the TIP122 by STMicroelectronics, the TIP127 by Jiangsu Changjing Electronics Technology (CJ), the TIP127 by STMicroelectronics and the BDW94C by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
