AI replacement insight

Electrical riskmedium

Resistance value differs and power rating lacks safety margin.

Package risklow

All candidates use the same 0603 package.

Sourcing risklow

Candidates are from active manufacturers like Yageo and FOJAN.

Can it be replaced directly?

No direct drop-in replacement is identified. All candidates require review due to different resistance values and lack of power rating margin.

Best replacement path

Use a parametric alternative with a slightly different resistance value after engineering validation.

Main risk

The primary risk is the change in resistance, which could alter circuit timing, biasing, or feedback loops.
