Questions

Is there a KiCad symbol and footprint for the FS431M?

Yes. The symbol is EasyEDA_Cloud:TL431_C55807316 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 FS431M?

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

Where is the FS431M datasheet?

FOSAN publishes it: the Datasheet link on this page opens it.

Where can I order the FS431M?

JLCPCB lists it as part C2926145, with 10 in stock; the sellers' links on this page open their listings.

What can replace the FS431M?

Parts like it in the library: the TL431 by Guangdong Hottech, the TL431 by FOSAN, the TL431 by JSMSEMI and the TL431 by AnBon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
