Questions

Is there a KiCad symbol and footprint for the AD8421ARMZ-R7?

Yes. The symbol is Amplifier_Instrumentation:AD8421ARMZ and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the AD8421ARMZ-R7?

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

Where is the AD8421ARMZ-R7 datasheet?

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

Where can I order the AD8421ARMZ-R7?

JLCPCB lists it as part C153202, with 489 in stock; the sellers' links on this page open their listings.

What can replace the AD8421ARMZ-R7?

Parts like it in the library: the AD8421ARMZ by Analog Devices, the AD8421BRMZ by Analog Devices, the AD8421BRMZ-R7 by Analog Devices and the AD8421ARMZ-RL by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
