Is there a KiCad symbol and footprint for the LM7121IM5?
Yes. The symbol is EasyEDA_Cloud:OPA343NA-HX and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM7121IM5?
SOT-23-5, with 5 pins. Its footprint is drawn on this page.
Where is the LM7121IM5 datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM7121IM5?
JLCPCB lists it as part C2869360, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM7121IM5?
Parts like it in the library: the LM321-TR by Gainsil, the LM321H-TR by Gainsil, the LMV321B-TR by 3PEAK and the OPA365AIDBV by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
