Questions

Is there a KiCad symbol and footprint for the MMBTA56?

Yes. The symbol is Transistor_BJT:MMBTA56 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 MMBTA56?

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

Where is the MMBTA56 datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the MMBTA56?

JLCPCB lists it as part C42765031, with 3,950 in stock; the sellers' links on this page open their listings.

What can replace the MMBTA56?

Parts like it in the library: the S8050 by YONGYUTAI, the MMBTA92 by hongjiacheng, the MMBTA42 by hongjiacheng and the MMBT2907ALT1G by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
