Questions

Is there a KiCad symbol and footprint for the MMSTA14?

Yes. The symbol is EasyEDA_Cloud:MMBTA14LT1HTSA1 and the footprint Package_TO_SOT_SMD:SOT-323_SC-70, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MMSTA14?

SOT-323, with 3 pins. Its footprint is drawn on this page.

Where is the MMSTA14 datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the MMSTA14?

JLCPCB lists it as part C5249119, with 4,407 in stock; the sellers' links on this page open their listings.

What can replace the MMSTA14?

Parts like it in the library: the MMBTA14W by STMicroelectronics, the MMSTA64 by Diodes Incorporated, the MMSTA13-7-F by Diodes Incorporated and the MMSTA63-7-F by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
