Questions

Is there a KiCad symbol and footprint for the CD431?

Yes. The symbol is EasyEDA_Cloud:TL431BQDBZR-JSM 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 CD431?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the CD431 datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the CD431?

JLCPCB lists it as part C77811, with 26,920 in stock; the sellers' links on this page open their listings.

What can replace the CD431?

Parts like it in the library: the TL431 by FOSAN, the AZ431AN-ATRE1 by Diodes Incorporated, the AZ431AN-ATRG1 by Diodes Incorporated and the TL431 by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
