Is there a KiCad symbol and footprint for the STEF12PUR?
Yes. The symbol is EasyEDA_Cloud:STEF12PUR and the footprint EasyEDA_Cloud:VSON-10_L3.0-W3.0-P0.50-TL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the STEF12PUR?
DFN-10-EP(3x3), with 11 pins. Its footprint is drawn on this page.
Where is the STEF12PUR datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STEF12PUR?
JLCPCB lists it as part C2155726, with 0 in stock; the sellers' links on this page open their listings.
What can replace the STEF12PUR?
Parts like it in the library: the TCKE812NA,RF by Toshiba, the TPS26620DRC by Texas Instruments and the TPS16416DRC by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
