Overview

The TIP31A is a bipolar made by STMicroelectronics in a TO-220 package with 3 pins. -65℃~+150℃ 1 NPN 1.2V 25 300uA 3A 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-T, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C10628).

Questions

Is there a KiCad symbol and footprint for the TIP31A?

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-T, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TIP31A?

TO-220, with 3 pins. Its footprint is drawn on this page.

Where is the TIP31A datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the TIP31A?

JLCPCB lists it as part C10628, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TIP31A?

Parts like it in the library: the MJE15032 by onsemi, the MOT13007MA by MOT, the BUL38D by STMicroelectronics and the BD810 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
