Is there a pin-compatible replacement for GRM31C5C1H154JE02L?

Yes, several parts share the 1206 package, making them pin-compatible. However, none are electrically identical. Candidates with the correct C0G dielectric have lower capacitance, requiring circuit validation.

What risks should I check before replacing GRM31C5C1H154JE02L?

The primary risk is substituting the stable C0G dielectric with an unstable type like X7R, which can cause circuit failure. Also, verify that any change in capacitance value is acceptable for your application's performance.

GRM31C5C1H154JE02L Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

GRM31C5C1H154JE02L is a 150nF, 50V, 1206 C0G capacitor offering high stability. Finding a direct replacement is challenging due to the specific combination of high capacitance and stable C0G dielectric.

AI replacement insight

Electrical riskhigh

Dielectric type and capacitance value are critical and differ in most candidates.

Package risklow

All candidates share the same 1206 package, ensuring physical fit.

Can it be replaced directly?

No direct, drop-in replacement has been identified. All viable candidates require a parametric trade-off on capacitance.

Best replacement path

Search for a C0G/NP0 capacitor in a 1206 package with capacitance ≥ 150nF and voltage ≥ 50V.

Main risk

Substituting the stable C0G dielectric with a less stable X7R type, which is unsuitable for precision applications.

Recommended alternatives

An NP0/C0G capacitor in the same package and voltage, but with lower capacitance (100nF).
