Questions

Is there a KiCad symbol and footprint for the AD8421BRZ-R7?

Yes. The symbol is Amplifier_Instrumentation:AD8421BRZ 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 AD8421BRZ-R7?

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

Where is the AD8421BRZ-R7 datasheet?

Analog Devices publishes it: the Datasheet link on this page opens it.

Where can I order the AD8421BRZ-R7?

JLCPCB lists it as part C652816, with 2,229 in stock; the sellers' links on this page open their listings.

What can replace the AD8421BRZ-R7?

Parts like it in the library: the AD8421ARZ-R7 by Analog Devices, the AD620ARZ-REEL(TOKMAS) by Tokmas, the AD620ARZ-REEL7(TOKMAS) by Tokmas and the INA128UA/2K5(TOKMAS) by Tokmas. Check their datasheets: a part that fits the footprint may still differ in its ratings.
