What risks should I check before replacing GRM155R61A104KA01D?

The main risk is the change in dielectric from X5R to X7R, which affects how capacitance changes with temperature and DC voltage. While X7R is generally better, you should verify its performance in your specific circuit, especially for timing or precision filtering applications.

GRM155R61A104KA01D is a 0.1µF 10V X5R capacitor in an 0402 package that is Not Recommended for New Designs (NRND). We recommend exploring active upgrade paths with improved voltage and temperature characteristics.

AI replacement insight

Electrical risklow

Upgrading voltage and dielectric (X5R to X7R) is generally safe but requires verification.

Package risklow

All strong candidates share the same 0402 package, ensuring form-fit compatibility.

Sourcing risklow

Target is NRND; recommended alternatives are active and widely available.

Can it be replaced directly?

Direct replacement for GRM155R61A104KA01D should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The best replacements are active AEC-Q200 parts like GRT155R71H104KE01D (50V) or GRT155R71C104KE01D (16V), which offer higher voltage and a wider temperature range.

Main risk

The primary risk when substituting is the change in dielectric from X5R to X7R. While X7R is often an upgrade, its capacitance vs. temperature and DC bias curves differ and should be verified for sensitive applications.

Recommended alternatives

A near-identical match for key electricals and package, but also has an NRND lifecycle status.
