Is there a pin-compatible replacement for 0603WAF1431T5E?

Yes, several candidates like FRC0603F1401TS and CRCW06031K50FKEA share the same 0603 package and are pin-compatible. However, their resistance values differ, so they are not drop-in replacements without engineering review.

What risks should I check before replacing 0603WAF1431T5E?

The primary risk is the resistance mismatch. The target is 1.43kΩ, while alternatives range from 1.37kΩ to 1.5kΩ. You must verify if this deviation is acceptable for your circuit's performance, especially in precision applications like voltage dividers or filter circuits.
