Questions
Is there a KiCad symbol and footprint for the MMFTN123K?
Yes. 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 MMFTN123K?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMFTN123K datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MMFTN123K?
JLCPCB lists it as part C7464204, with 915 in stock; the sellers' links on this page open their listings.
What can replace the MMFTN123K?
Parts like it in the library: the AS2324 by AnBon, the 5N10-MS by MSKSEMI, the PJM10H01PSA by PJSEMI and the AP1002 by ALLPOWER. Check their datasheets: a part that fits the footprint may still differ in its ratings.
