Is there a pin-compatible replacement for AC0603FR-071K3L?

Yes, parts like FOJAN FRC0603F1301TS are pin-compatible, sharing the same 0603 package and electrical parameters. However, it is not a direct drop-in for automotive applications because it lacks AEC-Q200 qualification.

What risks should I check before replacing AC0603FR-071K3L?

The main risk is substituting a non-AEC-Q200 qualified part into an automotive system, which can compromise reliability. Also check for technology differences (Thick vs. Thin Film) and any parametric deviations in resistance, tolerance, or TCR.
