Is there a pin-compatible replacement for GRM1555C1H682GE01D?

Yes, several 0402 capacitors are pin-compatible. GRM1555C1H682JE01D is a strong candidate that matches most parameters. Other pin-compatible parts with X7R dielectrics exist, but they are functional downgrades and require careful engineering review.

What risks should I check before replacing GRM1555C1H682GE01D?

The main risks are changes in capacitance tolerance and dielectric type. The target has a tight ±2% tolerance and a very stable C0G dielectric. A substitute with a wider tolerance or a less stable X7R dielectric can affect circuit accuracy and performance, especially with temperature changes.

The Murata GRM1555C1H682GE01D is a high-precision 6.8nF 50V capacitor in an 0402 package, featuring a stable C0G dielectric and tight ±2% tolerance. Finding a substitute requires careful matching of these key parameters.

AI replacement insight

Electrical riskhigh

Using an X7R part introduces significant capacitance variation with temperature and voltage.

Package risklow

Many 0402 package alternatives are available and should be physically compatible.

Can it be replaced directly?

No exact 1-to-1 replacement has been identified. The closest alternative is GRM1555C1H682JE01D from the same Murata series, which has a slightly wider tolerance of ±5%.

Best replacement path

For most applications, the best path is to use GRM1555C1H682JE01D and verify that the circuit can accommodate the ±5% tolerance. For precision applications, re-evaluation may be necessary.

Main risk

The primary risk is substituting with a part that has a different dielectric (e.g., X7R instead of C0G) or a wider tolerance, which can negatively impact performance in timing, filtering, or RF circuits.

Recommended alternatives

Same Murata series with identical C0G dielectric and voltage, but a slightly wider ±5% tolerance.
