Questions

Is there a KiCad symbol and footprint for the 2SA812?

Yes. the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 2SA812?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the 2SA812 datasheet?

CBI publishes it: the Datasheet link on this page opens it.

Where can I order the 2SA812?

JLCPCB lists it as part C51315017, with 1,442 in stock; the sellers' links on this page open their listings.

What can replace the 2SA812?

Parts like it in the library: the MMBT3904 by hongjiacheng, the S8050 by hongjiacheng, the SS8050 by hongjiacheng and the MMBT5551 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
