Is there a KiCad symbol and footprint for the UTC7312?
Yes. The symbol is EasyEDA_Cloud:UTC7312 and the footprint Package_DIP:DIP-14_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the UTC7312?
DIP-14, with 14 pins. Its footprint is drawn on this page.
Where is the UTC7312 datasheet?
YW publishes it: the Datasheet link on this page opens it.
Where can I order the UTC7312?
JLCPCB lists it as part C557811, with 0 in stock; the sellers' links on this page open their listings.
What can replace the UTC7312?
Parts like it in the library: the XD3403 by XINLUDA and the INA2137PA by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
