Overview
The AH421 is a hall Sensor made by Alfa in a TO-92S package with 3 pins. -40℃~+125℃ 3.5V~40V 4mT 6mA 6mT Open Collector Unipolar TO-92S Hall Switches ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:SLSS341R-3, from EasyEDA) and its footprint (Package_TO_SOT_THT:TO-92S, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2690105).

Questions
Is there a KiCad symbol and footprint for the AH421?
Yes. The symbol is EasyEDA_Cloud:SLSS341R-3 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 AH421?
TO-92S, with 3 pins. Its footprint is drawn on this page.
Where is the AH421 datasheet?
Alfa publishes it: the Datasheet link on this page opens it.
Where can I order the AH421?
JLCPCB lists it as part C2690105, with 0 in stock; the sellers' links on this page open their listings.
What can replace the AH421?
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.
