Is there a KiCad symbol and footprint for the TO-12?
Yes. The symbol is EasyEDA_Cloud:TA-12 and the footprint EasyEDA_Cloud:SW-SMD_EM-12KP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TO-12?
SMD,P=2.54mm, with 24 pins. Its footprint is drawn on this page.
Where is the TO-12 datasheet?
Yuandi publishes it: the Datasheet link on this page opens it.
Where can I order the TO-12?
JLCPCB lists it as part C703808, with 38 in stock; the sellers' links on this page open their listings.
What can replace the TO-12?
Parts like it in the library: the EM-12KP by HRO Electronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
