Questions

Is there a KiCad symbol and footprint for the STR2550?

Yes. The symbol is Pinmap_Generic:Q_PNP_1B_2E_3C and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the STR2550?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the STR2550 datasheet?

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

Where can I order the STR2550?

JLCPCB lists it as part C377933, with 6,087 in stock; the sellers' links on this page open their listings.

What can replace the STR2550?

Parts like it in the library: the S8050 by YONGYUTAI, the S8550 by YONGYUTAI, the 8550M-D by Foshan Blue Rocket Elec and the SS8550 by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
