AI replacement insight
Electrical riskmedium
Candidate power rating does not meet the 1.5x safety margin.
Package risklow
All viable candidates share the same 0603 package.
Can it be replaced directly?
No direct drop-in replacement has been identified that meets all engineering safety rules. 0603WAF330LT5E is a close match but requires review.
Best replacement path
Use a parametric alternative like 0603WAF330LT5E after verifying power dissipation, or search for a part with at least a 0.15W power rating.
Main risk
Insufficient power handling capability, which could lead to premature failure if the circuit operates near the component's power limit.
