AI replacement insight

Electrical riskhigh

Resistance, tolerance, and TCR mismatches can impact circuit performance and stability.

Package risklow

All candidates share the same 0402 package, ensuring physical compatibility.

Sourcing riskhigh

Using a non-AEC-Q200 part in an automotive application is a major compliance and reliability risk.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates have significant parametric differences or lack the target's AEC-Q200 qualification.

Best replacement path

Search for an AEC-Q200 qualified, thin film, 14.3kΩ resistor with ≤0.5% tolerance and ≤25ppm/°C TCR. If unavailable, evaluate parametric alternatives.

Main risk

The primary risks are resistance deviation affecting circuit accuracy and the lack of AEC-Q200 automotive qualification in candidates.

Recommended alternatives

A high-precision alternative with better tolerance and matching TCR, but a different resistance value.
