Questions

Is there a KiCad symbol and footprint for the INA121P?

Yes. The symbol is EasyEDA_Cloud:INA121UAE4 and the footprint Package_DIP:DIP-8_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 INA121P?

PDIP-8, with 8 pins. Its footprint is drawn on this page.

Where is the INA121P datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the INA121P?

JLCPCB lists it as part C1347772, with 0 in stock; the sellers' links on this page open their listings.

What can replace the INA121P?

Parts like it in the library: the INA128PA by Texas Instruments, the INA129P by Texas Instruments, the INA131AP by Texas Instruments and the AD620ANZ by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the INA121P?

3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
