Questions

Is there a KiCad symbol and footprint for the LM431ACMX?

Yes. The symbol is EasyEDA_Cloud:LM431ACM 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 LM431ACMX?

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

Where is the LM431ACMX datasheet?

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

Where can I order the LM431ACMX?

JLCPCB lists it as part C2156597, with 749 in stock; the sellers' links on this page open their listings.

What can replace the LM431ACMX?

Parts like it in the library: the TL431ACD by Texas Instruments, the TL431AID by Texas Instruments, the TL431BVD by onsemi and the TL1431AIYDT by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
