Questions
Is there a KiCad symbol and footprint for the TL431?
Yes. The symbol is EasyEDA_Cloud:TL431BMFDT-MS 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?
YFSEMI publishes it: the Datasheet link on this page opens it.
Where can I order the TL431?
JLCPCB lists it as part C2887585, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TL431?
Parts like it in the library: the LM431BIM3/NOPB by Texas Instruments, the ZTL431AFFTA by Diodes Incorporated, the ZTL432AFFTA by Diodes Incorporated and the BL431(0.5%) by Galaxy Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
