Overview
The LM393M is a comparator made by onsemi in a SOIC-8_3.9x4.9x1.27P package with 8 pins. SOIC-8 Comparators ROHS.
PCBKit's library has its KiCad symbol (Comparator:LM393, from KiCad's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C258241).

Is there a KiCad symbol and footprint for the LM393M?
Yes. The symbol is Comparator:LM393 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM393M?
SOIC-8_3.9x4.9x1.27P, with 8 pins. Its footprint is drawn on this page.
Where can I order the LM393M?
JLCPCB lists it as part C258241, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM393M?
Parts like it in the library: the LM393D by onsemi, the LM393BID by Texas Instruments, the LM393DT by STMicroelectronics and the LM2903BID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
