Is there a pin-compatible replacement for RL0603E024M250K?

Several candidates share the 0603 package and are physically compatible. However, electrical differences in clamping voltage and capacitance mean they are not drop-in replacements and require engineering review.

What risks should I check before replacing RL0603E024M250K?

Key risks include mismatched clamping voltage, which affects the protection level, and different capacitance, which can degrade high-speed signal integrity. Also verify technology differences (Varistor vs. TVS Diode).
