Questions
Is there a KiCad symbol and footprint for the TL431B?
Yes. The symbol is EasyEDA_Cloud:TL431QPK-TP and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TL431B?
SOT-89-3, with 3 pins. Its footprint is drawn on this page.
Where is the TL431B datasheet?
Slkor publishes it: the Datasheet link on this page opens it.
Where can I order the TL431B?
JLCPCB lists it as part C2936044, with 1,004 in stock; the sellers' links on this page open their listings.
What can replace the TL431B?
Parts like it in the library: the CJ431 by Jiangsu Changjing Electronics Technology (CJ), the AZ431AR-ATRE1 by Diodes Incorporated, the MMBT431LT1 by ALJ and the TL431AIPK by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
