AI replacement insight

Electrical riskmedium

Resistance deviation requires validation in the specific application.

Package risklow

All viable candidates use the same 0402 package.

Can it be replaced directly?

No direct, drop-in replacement has been identified. All viable candidates have minor parametric differences in resistance that require engineering review.

Best replacement path

Parametric alternatives with slightly different resistance values from the same manufacturer series.

Main risk

Resistance value deviation from the original 52.3 kΩ, which could impact circuit performance.

Recommended alternatives

Parametric alternative with slightly lower resistance (49.9kΩ) in the same 0402 package.
