AEC-Q200 qualified 680Ω 1% resistor in the same 0402 package. Power rating matches target but requires review for safety margin.
Find substitutes for the UNI-ROYAL 0402WGF6650TCE, a 665Ω 1% 1/16W 0402 thick film resistor. Alternatives with similar or improved parameters are available but require review of power rating and resistance values.
Power rating matches target but lacks safety margin; resistance values differ slightly.
All top candidates use the same 0402 package, ensuring form-fit compatibility.
No verified direct drop-in replacement has been identified. All candidates require engineering review, primarily for power rating and resistance tolerance.
The Yageo AC0402FR-07680RL is a strong candidate, offering very close resistance and AEC-Q200 qualification, but requires power handling review.
The main risk is ensuring the substitute's power rating is sufficient for the application, as candidates match the target's rating but do not exceed it.
