Questions
Is there a KiCad symbol and footprint for the LM397MF?
Yes. The symbol is Comparator:LM397 and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM397MF?
SOT-23-5, with 5 pins. Its footprint is drawn on this page.
Where is the LM397MF datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM397MF?
JLCPCB lists it as part C105497, with 81 in stock; the sellers' links on this page open their listings.
What can replace the LM397MF?
Parts like it in the library: the LMV331IDBV by Texas Instruments, the TLV7031DBV by Texas Instruments, the LMV331TP-TR by 3PEAK and the RS8901XF by Jiangsu RUNIC Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the LM397MF?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
