Is there a KiCad symbol and footprint for the TL431ACZ?
Yes. The symbol is Regulators:TL431ACZ and the footprint Package_TO_SOT_THT:TO-92L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TL431ACZ?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the TL431ACZ datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the TL431ACZ?
JLCPCB lists it as part C2802048, with 1,919 in stock; the sellers' links on this page open their listings.
What can replace the TL431ACZ?
Parts like it in the library: the TL431(0.5%) by UMW, the TL431(TO92)-TD by TDSEMIC, the TL431C by HTC and the TL431L by Slkor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
