Is there a KiCad symbol and footprint for the TL431L?
Yes. The symbol is EasyEDA_Cloud:TL431QPK-TP 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 TL431L?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the TL431L datasheet?
Slkor publishes it: the Datasheet link on this page opens it.
Where can I order the TL431L?
JLCPCB lists it as part C5155530, with 167 in stock; the sellers' links on this page open their listings.
What can replace the TL431L?
Parts like it in the library: the TL431C by HTC, the H431LKA by HY Elec, the LM285Z-2.5-TO-92 by DDF and the LM385Z-2.5-TO-92 by DDF. Check their datasheets: a part that fits the footprint may still differ in its ratings.
