Questions

Is there a KiCad symbol and footprint for the TL431CPK?

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 TL431CPK?

SOT-89-3, with 3 pins. Its footprint is drawn on this page.

Where is the TL431CPK datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the TL431CPK?

JLCPCB lists it as part C507258, with 3,345 in stock; the sellers' links on this page open their listings.

What can replace the TL431CPK?

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.
