Is there a KiCad symbol and footprint for the TL431?
Yes. The symbol is EasyEDA_Cloud:AZ432ANTR-TP 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?
LGE publishes it: the Datasheet link on this page opens it.
Where can I order the TL431?
JLCPCB lists it as part C7425381, with 3,669 in stock; the sellers' links on this page open their listings.
What can replace the TL431?
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.
