Questions

Is there a KiCad symbol and footprint for the MMBTA94?

Yes. The symbol is Transistor_BJT:MMBTA94 and 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 MMBTA94?

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

Where is the MMBTA94 datasheet?

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

Where can I order the MMBTA94?

JLCPCB lists it as part C22458949, with 71,202 in stock; the sellers' links on this page open their listings.

What can replace the MMBTA94?

Parts like it in the library: the S8050 by YONGYUTAI, the MMBTA92 by hongjiacheng, the MMBTA44 by hongjiacheng and the MMBTA42 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the MMBTA94?

4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
