Is there a KiCad symbol and footprint for the KA431SMFTF?
Yes. The symbol is EasyEDA_Cloud:TPR431B-S3TR and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the KA431SMFTF?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the KA431SMFTF datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the KA431SMFTF?
JLCPCB lists it as part C232815, with 0 in stock; the sellers' links on this page open their listings.
What can replace the KA431SMFTF?
Parts like it in the library: the TL431 by Guangdong Hottech, the TL431 by FOSAN, the AZ431AN-ATRE1 by Diodes Incorporated and the AZ431AN-ATRG1 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the KA431SMFTF?
2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
