Questions

Is there a KiCad symbol and footprint for the TL1431CDT?

Yes. The symbol is EasyEDA_Cloud:TL431ACDT-TP and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TL1431CDT?

SO-8, with 8 pins. Its footprint is drawn on this page.

Where is the TL1431CDT datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the TL1431CDT?

JLCPCB lists it as part C5267731, with 101 in stock; the sellers' links on this page open their listings.

What can replace the TL1431CDT?

Parts like it in the library: the TL431BVD by onsemi, the TL1431AIYDT by STMicroelectronics, the TL431AID by onsemi and the TL1431IDT by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
