Overview
The OHN3040U is a linear Hall Sensor made by OPTEK in a TO-92 package with 3 pins. 4.5V~24V 4mA TO-92 Hall Switches ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:OHS3175U, from EasyEDA) and its footprint (Package_TO_SOT_THT:TO-92L, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1559584).

Is there a KiCad symbol and footprint for the OHN3040U?
Yes. The symbol is EasyEDA_Cloud:OHS3175U 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 OHN3040U?
TO-92, with 3 pins. Its footprint is drawn on this page.
Where is the OHN3040U datasheet?
OPTEK publishes it: the Datasheet link on this page opens it.
Where can I order the OHN3040U?
JLCPCB lists it as part C1559584, with 0 in stock; the sellers' links on this page open their listings.
What can replace the OHN3040U?
