Overview
The FMMT491 is a bipolar made by TWGMC in a SOT-23 package with 3 pins.
PCBKit's library has its KiCad symbol (Transistors:NPN B1 E2 C3, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 1,505 are in stock at JLCPCB (part C47283705).

Questions
Is there a KiCad symbol and footprint for the FMMT491?
Yes. The symbol is Transistors:NPN B1 E2 C3 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 FMMT491?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the FMMT491 datasheet?
TWGMC publishes it: the Datasheet link on this page opens it.
Where can I order the FMMT491?
JLCPCB lists it as part C47283705, with 1,505 in stock; the sellers' links on this page open their listings.
What can replace the FMMT491?
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.
