Is there a pin-compatible replacement for GRM1555C1H472JE01D?

Yes, parts like GCM155R71H472KA37D and CL05B472KB5NNNC share the same 0402 package and are pin-compatible. However, they are not electrically equivalent due to different dielectrics.

What risks should I check before replacing GRM1555C1H472JE01D?

The main risk is the dielectric change from stable C0G to less-stable X7R. This can affect performance in timing, filtering, or resonant circuits. Also, check for tolerance differences (e.g., ±5% vs. ±10%).

GRM1555C1H472JE01D Alternatives, Datasheet & Cross Reference | Murata Manufacturing Co., Ltd.

GRM1555C1H472JE01D is a high-stability 4.7nF 50V C0G ceramic capacitor in a 0402 package. Finding a substitute requires careful attention to the dielectric material to ensure circuit performance is not compromised.

AI replacement insight

Electrical riskhigh

Dielectric mismatch (C0G vs. X7R) affects stability over temperature and voltage.

Package risklow

Alternatives in the same 0402 package are readily available.

Can it be replaced directly?

No direct, fully equivalent replacement has been verified. Available alternatives have significant electrical differences.

Best replacement path

Search for another 0402 capacitor with 4.7nF capacitance, 50V rating, and a C0G (or NP0) dielectric.

Main risk

The primary risk is substituting the stable C0G dielectric with a less stable material like X7R, which can degrade circuit performance.

Recommended alternatives

A cross-vendor option with matching size and values, but a less stable X7R dielectric.
