Is there a KiCad symbol and footprint for the MMBTA14L?
Yes. The symbol is EasyEDA_Cloud:MMBTA14LT1G 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 MMBTA14L?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMBTA14L datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MMBTA14L?
JLCPCB lists it as part C232604, with 6,089 in stock; the sellers' links on this page open their listings.
What can replace the MMBTA14L?
Parts like it in the library: the BCV47 by Jiangsu Changjing Electronics Technology (CJ), the MMBT6427L by onsemi, the MMBTA64L by onsemi and the FMMT634TA by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
