Is there a KiCad symbol and footprint for the KA431DTF?
Yes. The symbol is EasyEDA_Cloud:TL1431CZ-AP and the footprint EasyEDA_Cloud:TO-92-3_L4.9-W3.7-P1.27-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the KA431DTF?
TO-92-3, with 3 pins. Its footprint is drawn on this page.
Where is the KA431DTF datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the KA431DTF?
JLCPCB lists it as part C905088, with 0 in stock; the sellers' links on this page open their listings.
What can replace the KA431DTF?
Parts like it in the library: the AD680JTZ by Analog Devices, the LT1029CZ#TRPBF by Analog Devices, the LT1034CZ-2.5#PBF by Analog Devices and the TL431A by FeiHong. Check their datasheets: a part that fits the footprint may still differ in its ratings.
