Is there a KiCad symbol and footprint for the FMMT493?
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 FMMT493?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the FMMT493 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the FMMT493?
JLCPCB lists it as part C77886, with 155,969 in stock; the sellers' links on this page open their listings.
What can replace the FMMT493?
Parts like it in the library: the SS8050 by hongjiacheng, the SS8050 by MDD, the SS8550 by hongjiacheng and the SS8550 Y2 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
