Questions
Is there a KiCad symbol and footprint for the MMBTA42?
Yes. The symbol is Transistor_BJT:MMBTA42 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 MMBTA42?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMBTA42 datasheet?
JUXING publishes it: the Datasheet link on this page opens it.
Where can I order the MMBTA42?
JLCPCB lists it as part C5279928, with 2,745 in stock; the sellers' links on this page open their listings.
What can replace the MMBTA42?
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.
