AI replacement insight

Electrical riskmedium

Resistance differs by 2-6%, requiring circuit validation.

Package risklow

Candidates share the same 1206 package.

Can it be replaced directly?

No direct drop-in replacement was found. Alternatives require review due to resistance value differences of 2-6%.

Best replacement path

Parametric alternatives with slightly different resistance values (470Ω or 510Ω) and higher power ratings (0.5W) are available.

Main risk

The primary risk is the change in resistance, which may affect circuit performance in precision applications.

Recommended alternatives

A 1206 resistor with higher power rating (0.5W) but different resistance (510Ω); requires engineering review.
