Is there a pin-compatible replacement for GCM1555C1H6R8BA16D?

Yes, several 0402 package capacitors are pin-compatible, but none are exact drop-in replacements. Candidates like GCM1555C1H6R8CA16D have wider tolerance, and others may have different capacitance or lack automotive-grade qualification.

What risks should I check before replacing GCM1555C1H6R8BA16D?

Key risks include: 1) Application Grade: Ensure the replacement is AEC-Q200 qualified for automotive use. 2) Tolerance: Verify your circuit can handle a wider tolerance (e.g., ±0.25pF vs ±0.1pF). 3) Capacitance: Check if a slight capacitance shift is acceptable.

GCM1555C1H6R8BA16D is a high-precision 6.8pF, 50V automotive-grade (AEC-Q200) ceramic capacitor in a 0402 package. Finding a substitute requires matching its tight tolerance and automotive qualification.

AI replacement insight

Electrical riskmedium

Tolerance and capacitance deviations require analysis.

Package risklow

All kept candidates are 0402 package.

Sourcing riskhigh

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

Can it be replaced directly?

No direct drop-in replacement was found. All candidates have minor parametric differences (capacitance or tolerance) or lack automotive qualification, requiring engineering review.

Best replacement path

The best path is to find another AEC-Q200 qualified 'GCM' series capacitor. GCM1555C1H6R8CA16D is a strong candidate if the wider ±0.25pF tolerance is acceptable.

Main risk

The main risk is using a non-automotive grade part or a part with wider tolerance, which could affect circuit performance and reliability in harsh environments.

Recommended alternatives

Automotive-grade match with identical capacitance but wider tolerance (±0.25pF).
