Is there a KiCad symbol and footprint for the LM3401MMX?
Yes. The symbol is Celestial_Driver_LED:TI LM3401MM and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM3401MMX?
MSOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM3401MMX datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM3401MMX?
JLCPCB lists it as part C11131, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM3401MMX?
Parts like it in the library: the IMP528EMA/T by Daily Silver Imp Microelectronics and the IMP560EMA/T by Daily Silver Imp Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
