Questions

Is there a KiCad symbol and footprint for the MMBFJ201?

Yes. The symbol is EasyEDA_Cloud:MMBFJ202 and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MMBFJ201?

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

Where is the MMBFJ201 datasheet?

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

Where can I order the MMBFJ201?

JLCPCB lists it as part C891687, with 20,001 in stock; the sellers' links on this page open their listings.

What can replace the MMBFJ201?

Parts like it in the library: the MMBFJ112 by onsemi, the MMBFJ110 by onsemi, the IF1320ST3TR by InterFET and the IF140AST3 by InterFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.
