Is there a KiCad symbol and footprint for the OPA121KM?
Yes. The symbol is EasyEDA_Cloud:OPA121KM and the footprint EasyEDA_Cloud:TO-99-8_TI_LMC, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the OPA121KM?
TO-99-8, with 8 pins. Its footprint is drawn on this page.
Where is the OPA121KM datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the OPA121KM?
JLCPCB lists it as part C5817500, with 0 in stock; the sellers' links on this page open their listings.
What can replace the OPA121KM?
Parts like it in the library: the LM741H by Texas Instruments, the LM158H/883 by Texas Instruments, the LM258H by Texas Instruments and the LM741CH by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
