Overview

The STL73 is a bipolar made by STMicroelectronics in a TO-92-3 package with 3 pins. 1 NPN 1.1W 1.5A 10 1V 400V NPN TO-92-3 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1E_2C_3B, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-92-3_L4.8-W3.7-P1.27-L, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C3202006).

Questions

Is there a KiCad symbol and footprint for the STL73?

Yes. The symbol is Pinmap_Generic:Q_NPN_1E_2C_3B and the footprint EasyEDA_Cloud:TO-92-3_L4.8-W3.7-P1.27-L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STL73?

TO-92-3, with 3 pins. Its footprint is drawn on this page.

Where is the STL73 datasheet?

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

Where can I order the STL73?

JLCPCB lists it as part C3202006, with 0 in stock; the sellers' links on this page open their listings.

What can replace the STL73?

Parts like it in the library: the 3DD13003A by Jilin Sino-Microelectronics, the STL73D by STMicroelectronics, the FJN13003TA by onsemi and the LP395Z by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
