Overview

The MMBTA42-TP is a bipolar made by Micro Commercial Components in a SOT-23 package with 3 pins. -55℃~+150℃ 1 NPN 100nA 225mW 300V 40 500mA 500mV 50MHz 6V NPN SOT-23 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (Transistor_BJT:MMBTA42, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 4 are in stock at JLCPCB (part C78715). 1 open-source board in 1 repository on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the MMBTA42-TP?

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-TP?

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

Where is the MMBTA42-TP datasheet?

Micro Commercial Components publishes it: the Datasheet link on this page opens it.

Where can I order the MMBTA42-TP?

JLCPCB lists it as part C78715, with 4 in stock; the sellers' links on this page open their listings.

What can replace the MMBTA42-TP?

Parts like it in the library: the S8050 by hongjiacheng, the SS8050 by hongjiacheng, the MMBT5551 by hongjiacheng and the MMBT5401 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
