Questions
Is there a KiCad symbol and footprint for the KY1012?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2S_3D and the footprint EasyEDA_Cloud:SOT-523-3_L1.6-W0.8-P1.00-LS1.6-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the KY1012?
SOT-523-3, with 3 pins. Its footprint is drawn on this page.
Where is the KY1012 datasheet?
KY publishes it: the Datasheet link on this page opens it.
Where can I order the KY1012?
JLCPCB lists it as part C3029287, with 0 in stock; the sellers' links on this page open their listings.
What can replace the KY1012?
Parts like it in the library: the MMFTN3019E by STMicroelectronics, the CJ1012 C by Jiangsu Changjing Electronics Technology (CJ), the DMN2310UT by Diodes Incorporated and the SE2102E by SINO-IC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
