Is there a KiCad symbol and footprint for the MMUN2240L?
Yes. The symbol is EasyEDA_Cloud:DTC123JM-TP 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 MMUN2240L?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMUN2240L datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MMUN2240L?
JLCPCB lists it as part C891757, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MMUN2240L?
Parts like it in the library: the MMUN2233L by onsemi, the MMUN2211LT1G by onsemi, the PDTD123YT by Nexperia and the LMUN2232LT1G by Leshan Radio (LRC). Check their datasheets: a part that fits the footprint may still differ in its ratings.
