Is there a KiCad symbol and footprint for the LM7121IM?
Yes. The symbol is EasyEDA_Cloud:OPA353UA_2K5 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM7121IM?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the LM7121IM datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM7121IM?
JLCPCB lists it as part C1346094, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM7121IM?
Parts like it in the library: the TS922IDT by STMicroelectronics, the LMV358B-SR by 3PEAK, the MC33178D by onsemi and the BUF634AID by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
