Is there a KiCad symbol and footprint for the SM12OC?
Yes. 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 SM12OC?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SM12OC datasheet?
UMW publishes it: the Datasheet link on this page opens it.
Where can I order the SM12OC?
JLCPCB lists it as part C20417175, with 2,699 in stock; the sellers' links on this page open their listings.
What can replace the SM12OC?
Parts like it in the library: the PSM712-LF-T7 by PROTEK, the SM712 by DOWO, the CDSOT23-SM712-ES by ElecSuper and the SM712 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SM12OC?
2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
