Is there a KiCad symbol and footprint for the LM431SAIMFX?
Yes. The symbol is EasyEDA_Cloud:TPR431B-S3TR and the footprint EasyEDA_Cloud:SOT-23-3_L2.9-W1.3-P0.95-LS2.4-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM431SAIMFX?
SOT-23F-3, with 3 pins. Its footprint is drawn on this page.
Where is the LM431SAIMFX datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the LM431SAIMFX?
JLCPCB lists it as part C891360, with 13 in stock; the sellers' links on this page open their listings.
What can replace the LM431SAIMFX?
Parts like it in the library: the LM431SBIMFX by onsemi, the LM431SCIMFX by onsemi, the TPR6040F20-S3TR by 3PEAK and the TPR3325-S3TR by 3PEAK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
