Is there a pin-compatible replacement for 0603WAF4420T5E?

Yes, several parts like 0603WAF4220T5E and CRCW0603470RFKEA are pin-compatible in the same 0603 package. However, they are not electrically identical due to different resistance values and require engineering review.

What risks should I check before replacing 0603WAF4420T5E?

The main risk is the change in resistance. Check if the new value (e.g., 422Ω or 470Ω instead of 442Ω) is within your circuit's acceptable tolerance. Also confirm other parameters like power rating and TCR meet your design requirements.
