Is there a pin-compatible replacement for 0603WAF620KT5E?

Yes, FRC0603F6R20TS is a potential pin-compatible replacement as it shares the same 0603 package and primary electrical ratings. However, it is not a guaranteed drop-in replacement without first verifying the impact of its potentially higher TCR.

What risks should I check before replacing 0603WAF620KT5E?

Before replacing, check three main risks: 1) Temperature Coefficient (TCR), as substitutes may have higher values affecting stability over temperature. 2) Resistance Value, as some alternatives are close but not identical (e.g., 6.8Ω vs 6.2Ω). 3) Resistance Tolerance, as some options have a wider tolerance (e.g., ±5% vs ±1%).
