Overview
The TIP31AG is a bipolar made by onsemi in a TO-220 package with 3 pins. -65℃~+150℃ 1 NPN 1.2V 25 300uA 3A 3MHz 40W 5V 60V NPN TO-220 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1B_2C_3E, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C897229).

Is there a KiCad symbol and footprint for the TIP31AG?
Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2C_3E and the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TIP31AG?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the TIP31AG datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the TIP31AG?
JLCPCB lists it as part C897229, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TIP31AG?
Parts like it in the library: the BU406 by SPTECH, the D45VH10 by onsemi, the ST13005 by STMicroelectronics and the MJE15028 by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
