Questions

Is there a KiCad symbol and footprint for the LM431ACMX?

Yes. the footprint Package_SO:SO-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 LM431ACMX?

SOIC-8, with 5 pins. Its footprint is drawn on this page.

Where is the LM431ACMX datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the LM431ACMX?

JLCPCB lists it as part C905146, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM431ACMX?

Parts like it in the library: the TL1431QDG4 by Texas Instruments, the LM431CIMX by onsemi and the TL1431MDREPG4 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
