Is there a KiCad symbol and footprint for the TL431?
Yes. The symbol is EasyEDA_Cloud:TS432BCX 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 TL431?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the TL431 datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the TL431?
JLCPCB lists it as part C3025162, with 113,047 in stock; the sellers' links on this page open their listings.
What can replace the TL431?
Parts like it in the library: the RS431AYSF3 by Jiangsu RUNIC Tech and the GN431G 0.3% by GN Semic. Check their datasheets: a part that fits the footprint may still differ in its ratings.
