What risks should I check before replacing 0603WAF2801T5E?

Before replacing, verify the candidate's actual power rating from its datasheet, as source data is inconsistent. Also, confirm that a 75V working voltage, which matches the original part but lacks a safety margin, is acceptable for your circuit's operating conditions.

AI replacement insight

Electrical riskmedium

Candidate power ratings are suspect and voltage margin is not met.

Package risklow

All candidates share the same 0603 package.

Can it be replaced directly?

Direct replacement for 0603WAF2801T5E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with Datasheet verified or Strong match candidates for 0603WAF2801T5E, then review parametric alternatives for package and electrical fit.

Main risk

Data inconsistency in candidate power ratings and lack of voltage safety margin are the primary risks.

Recommended alternatives

Matches resistance and package, but requires review of inconsistent power rating data and voltage margin.
