Is there a KiCad symbol and footprint for the CD431?
Yes. 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?
DOWO publishes it: the Datasheet link on this page opens it.
Where can I order the CD431?
JLCPCB lists it as part C2988644, with 0 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 Guangdong Hottech, the TL431 by FOSAN, the AZ431AN-ATRE1 by Diodes Incorporated and the AZ431AN-ATRG1 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
