Questions

Is there a KiCad symbol and footprint for the ADR421AR?

Yes. The symbol is Regulators:ADR42x 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 ADR421AR?

SOIC8, with 8 pins. Its footprint is drawn on this page.

What can replace the ADR421AR?

Parts like it in the library: the LTA8062XS8/R8 by Linearin, the SD8568 by WAVE, the FH9926 by XIN FEI HONG and the LTC8836XS8/R8 by Linearin. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ADR421AR?

7 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
