Questions

Is there a KiCad symbol and footprint for the AD8421ARZ-R7(TOKMAS)?

Yes. The symbol is Amplifier_Instrumentation:AD8421ARZ 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 AD8421ARZ-R7(TOKMAS)?

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

Where is the AD8421ARZ-R7(TOKMAS) datasheet?

Tokmas publishes it: the Datasheet link on this page opens it.

Where can I order the AD8421ARZ-R7(TOKMAS)?

JLCPCB lists it as part C19184240, with 874 in stock; the sellers' links on this page open their listings.

What can replace the AD8421ARZ-R7(TOKMAS)?

Parts like it in the library: the AD620ARZ-REEL(TOKMAS) by Tokmas, the AD620ARZ-REEL7(TOKMAS) by Tokmas, the INA128UA/2K5(TOKMAS) by Tokmas and the MAX4460ESA+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
