Is there a pin-compatible replacement for GRM155D81C475ME15D?

Yes, parts like HGC0402R5475M250NTEJ are pin-compatible in the same 0402 package. However, they are not electrically identical due to having a different dielectric material (X5R vs. X6T), which results in a lower temperature rating. Engineering review is required.

What risks should I check before replacing GRM155D81C475ME15D?

The main risk is thermal. The original part is rated to 105°C (X6T dielectric), while the closest alternatives are rated to 85°C (X5R/X5S). You must verify that your application's operating temperature will not exceed 85°C to avoid component failure or significant performance degradation.

Finding a substitute for the Murata GRM155D81C475ME15D, a 4.7µF 16V 0402 capacitor, requires careful attention to the X6T dielectric. While pin-compatible parts exist, they often have a lower maximum operating temperature, which must be verified for your application.

AI replacement insight

Electrical riskmedium

Reduced operating temperature range requires application-level verification.

Package risklow

Pin-compatible alternatives in the same 0402 package are available.

Can it be replaced directly?

No direct drop-in replacement was found. All suitable candidates have a different dielectric (X5R or X5S) which results in a lower maximum operating temperature than the original X6T part.

Best replacement path

Review candidates like HGC0402R5475M250NTEJ, which match the package and key values but require verifying the application's temperature requirements.

Main risk

The primary risk is the dielectric mismatch, leading to a reduced maximum operating temperature from 105°C to 85°C.

Recommended alternatives

A 0402 capacitor with same capacitance but lower max temperature (85°C vs 105°C). Voltage is higher (25V).
