Is there a KiCad symbol and footprint for the MMBT4401?
Yes. The symbol is dk_Transistors-Bipolar-BJT-Single:MMBT4401_Obsolete 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 MMBT4401?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMBT4401 datasheet?
Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MMBT4401?
JLCPCB lists it as part C374999, with 2,344 in stock; the sellers' links on this page open their listings.
What can replace the MMBT4401?
Parts like it in the library: the CMN2922A by Cmos, the SI2318CDS by FUXINSEMI, the MMBT4403 by Galaxy Microelectronics and the PT2301A by HT. Check their datasheets: a part that fits the footprint may still differ in its ratings.
