Questions

Is there a KiCad symbol and footprint for the LM1972MX?

Yes. The symbol is EasyEDA_Cloud:LM1972MX_NOPB and the footprint Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM1972MX?

SOIC-20-300mil, with 20 pins. Its footprint is drawn on this page.

Where is the LM1972MX datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM1972MX?

JLCPCB lists it as part C2649339, with 144 in stock; the sellers' links on this page open their listings.

What can replace the LM1972MX?

Parts like it in the library: the IRS2461SXUMA1 by Infineon Technologies and the FAN7040MX by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
