Is there a pin-compatible replacement for GJM1555C1H330FB01D?

Yes, several parts like GJM1555C1H330GB01D and GCM1555C1H330FA16D share the 0402 package and are pin-compatible. However, you must verify functional differences like RF performance (Q-factor) and tolerance.

What risks should I check before replacing GJM1555C1H330FB01D?

Key risks include using a part with wider tolerance (e.g., ±2% or ±5%) or a general-purpose capacitor that lacks the high-Q performance needed for RF circuits, potentially degrading signal integrity.

GJM1555C1H330FB01D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

GJM1555C1H330FB01D is a 33pF 50V 1% C0G 0402 high-Q MLCC from Murata, for RF applications. Finding a substitute requires matching RF performance (Q-factor) and tolerance.

AI replacement insight

Electrical riskmedium

Substituting with a non-high-Q part or one with wider tolerance can affect circuit performance.

Package risklow

All candidates share the same 0402 package, ensuring form and fit compatibility.

Sourcing risklow

The target is active; avoid NRND substitutes unless for legacy repairs.

Can it be replaced directly?

No exact drop-in replacement is identified. The closest is GJM1555C1H330GB01D, which has a wider tolerance of ±2% versus the original's ±1%.

Best replacement path

The best path is to use another Murata GJM series part, like GJM1555C1H330GB01D, which only has a slightly wider tolerance.

Main risk

The main risk is substituting with a general-purpose capacitor, which may have a lower Q-factor and degrade performance in RF circuits.

Recommended alternatives

Active part from the same high-Q series with a slightly wider tolerance (±2%).
