Questions

Is there a KiCad symbol and footprint for the FMMT493TA?

Yes. The symbol is Pinmap_Generic:Q_NPN_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 FMMT493TA?

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

Where is the FMMT493TA datasheet?

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

Where can I order the FMMT493TA?

JLCPCB lists it as part C435889, with 12,669 in stock; the sellers' links on this page open their listings.

What can replace the FMMT493TA?

Parts like it in the library: the 8550M-D by Foshan Blue Rocket Elec, the SS8550 by MSKSEMI, the PBSS4160T by Nexperia and the S8550 2TY-TD(0.35) by TDSEMIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the FMMT493TA?

4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
