Murata Electronics
A form-fit compatible High-Q capacitor from the same series with slightly higher capacitance.
The Murata GJM1555C1H4R7BB01D is a 4.7pF 50V High-Q C0G capacitor in a 0402 package, common in RF circuits. Finding a replacement requires careful matching of capacitance, tolerance, and high-Q characteristics.
Capacitance changes affect circuit tuning. Q-factor mismatch from other series is also a major risk.
All reviewed candidates share the same 0402 package.
No direct, identical replacement was found. All candidates have different capacitance values and require circuit validation.
Use another capacitor from Murata's GJM series if your design can tolerate a different capacitance value. This maintains the critical High-Q performance.
The primary risk is the change in capacitance, which will affect the frequency response of timing or filter circuits.

| Feature / factor | GJM1555C1H4R7BB01D | GJM1555C1H5R6BB01D | GJM1555C1H8R2BB01D | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0402 (1005 metric) | 0402 (1005 metric) | - | 0402 (1005 metric) — Same package and pin count. | |
| Capacitance | 4.7 pF | 5.6 pF | - | 8.2 pF — Capacitance is significantly higher. | |
| Voltage | 50.0 V | 50.0 V | - | 50.0 V — Voltage rating is identical. | |
| Tolerance | ±0.1 pF | ±0.1 pF | - | ±0.1 pF — Absolute tolerance is identical. | |
| Series | GJM (High-Q) | GJM (High-Q) | - | GJM (High-Q) — Same High-Q series ensures similar performance characteristics. |
The best alternatives are other parts in Murata's GJM1555C1H series, like GJM1555C1H5R6BB01D (5.6pF), if your circuit can accommodate a slight capacitance change. This preserves the High-Q characteristic.
