Is there a KiCad symbol and footprint for the TL431CLPR?
Yes. The symbol is EasyEDA_Cloud:TL431QPK-TP and the footprint EasyEDA_Cloud:TO-92-3_L4.9-W3.7-P2.54-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TL431CLPR?
TO-92-3, with 3 pins. Its footprint is drawn on this page.
Where is the TL431CLPR datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the TL431CLPR?
JLCPCB lists it as part C352990, with 7,802 in stock; the sellers' links on this page open their listings.
What can replace the TL431CLPR?
Parts like it in the library: the AZ431AZ-ATRE1 by Diodes Incorporated, the TL431ACLPR by Texas Instruments, the TL431ILPR by Texas Instruments and the TL431CLPRP by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
