Is there a KiCad symbol and footprint for the AH431?
Yes. The symbol is EasyEDA_Cloud:AH431_C2691445 and the footprint Package_TO_SOT_THT:TO-92S, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the AH431?
TO-92S, with 3 pins. Its footprint is drawn on this page.
Where is the AH431 datasheet?
Alfa publishes it: the Datasheet link on this page opens it.
Where can I order the AH431?
JLCPCB lists it as part C2691445, with 84 in stock; the sellers' links on this page open their listings.
What can replace the AH431?
Parts like it in the library: the A1220LUA-T by Allegro MicroSystems, LLC, the SS496A1 by Honeywell, the A1326LUA-T by Allegro MicroSystems, LLC and the A1212LUA-T by Allegro MicroSystems, LLC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
