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?
TECH PUBLIC publishes it: the Datasheet link on this page opens it.
Where can I order the FMMT491?
JLCPCB lists it as part C5182078, with 1,487 in stock; the sellers' links on this page open their listings.
What can replace the FMMT491?
Parts like it in the library: the AO3400 by GOODWORK, the AP2300 by ALLPOWER, the AO3400A by Alpha & Omega Semiconductor and the AO3400A by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
