Questions

Is there a KiCad symbol and footprint for the INA2126U?

Yes. The symbol is EasyEDA_Cloud:INA2128PA and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the INA2126U?

SOIC-16, with 16 pins. Its footprint is drawn on this page.

Where is the INA2126U datasheet?

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

Where can I order the INA2126U?

JLCPCB lists it as part C2878004, with 14 in stock; the sellers' links on this page open their listings.

What can replace the INA2126U?

Parts like it in the library: the INA125U by Texas Instruments, the INA110KU by Texas Instruments, the INA125UA by Texas Instruments and the INA2126UA/2K5 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
