Is there a pin-compatible replacement for CQ0402BRNPO9BN4R7?

Yes, several 0402 capacitors like CC0402CRNPO9BN4R7 and CL05C4R7CB5NNNC are pin-compatible. However, they have relaxed electrical parameters (e.g., wider tolerance) and are not High-Q parts, requiring engineering review.

What risks should I check before replacing CQ0402BRNPO9BN4R7?

Key risks include wider capacitance tolerance (e.g., ±0.25pF vs ±0.1pF) and lower Q-factor if replacing the High-Q 'CQ' series with a general-purpose part. This can affect performance in RF filters, oscillators, and timing circuits.

AI replacement insight

Electrical riskmedium

Wider tolerance and lower Q-factor can impact performance in sensitive circuits.

Package risklow

Package is a standard 0402, ensuring mechanical compatibility.

Can it be replaced directly?

No direct, identical replacement was found. All suitable alternatives have a wider capacitance tolerance and are not specified as High-Q parts.

Best replacement path

Use a parametric alternative with the same capacitance, voltage, and package, but verify the impact of wider tolerance and lower Q-factor.

Main risk

The primary risk is functional, as the target is a High-Q capacitor for RF applications, while most alternatives are general-purpose with wider tolerance.

Recommended alternatives

A 4.7pF 50V 0402 capacitor with wider tolerance and for general-purpose use; not a High-Q part.
