Is there a pin-compatible replacement for ERJ3EKF2003V?

Yes, several pin-compatible replacements in the 0603 package exist. PTFR0603B200KN9 is an upgrade, while parts like RC0603JR-07200KL are pin-compatible but have weaker electrical specifications.

What risks should I check before replacing ERJ3EKF2003V?

The main risks are using a part with weaker tolerance (e.g., 5% vs 1%) or a worse Temperature Coefficient (TCR). Also, check for technology differences (Thick Film vs. Thin Film) which can affect pulse handling and high-frequency performance.
