Is there a KiCad symbol and footprint for the X0405MF?
Yes. The symbol is EasyEDA_Cloud:BT137-800D_C2901163 and the footprint EasyEDA_Cloud:TO-126_L7.8-W2.7-P2.30-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the X0405MF?
TO-126, with 3 pins. Its footprint is drawn on this page.
Where is the X0405MF datasheet?
KY publishes it: the Datasheet link on this page opens it.
Where can I order the X0405MF?
JLCPCB lists it as part C2831684, with 3 in stock; the sellers' links on this page open their listings.
What can replace the X0405MF?
Parts like it in the library: the BT134-600E by FUXINSEMI, the BT134-800E by FUXINSEMI, the BT134 by Jiangsu Changjing Electronics Technology (CJ) and the BT134-600E by KY. Check their datasheets: a part that fits the footprint may still differ in its ratings.
