Is there a pin-compatible replacement for HMK107B7104KAHT?

Yes, several capacitors like FCC0603B104K101CT and 06031C104K4T2A share the same 0603 package and key electrical ratings. However, they are not automotive-grade, so they are functional alternatives, not guaranteed drop-in replacements.

What risks should I check before replacing HMK107B7104KAHT?

The main risks are application grade and dielectric type. First, ensure a general-purpose capacitor is acceptable if replacing the AEC-Q200 qualified target. Second, if considering an alternative like the TDK part, verify your circuit can tolerate the different performance of an X7S dielectric compared to X7R.

Finding a substitute for the HMK107B7104KAHT, a 100nF, 100V, X7R ceramic capacitor in a 0603 package, requires careful attention to its AEC-Q200 automotive qualification. This page reviews several potential alternatives and highlights key differences to consider.

AI replacement insight

Electrical riskhigh

Using a part with a different dielectric (X7S) or a non-automotive part can affect circuit performance and reliability.

Package risklow

All suggested alternatives use the same standard 0603 package.

Can it be replaced directly?

No guaranteed direct replacement exists. While several parts match key electricals, the target's automotive (AEC-Q200) rating is a critical feature not present in most alternatives, requiring engineering review.

Best replacement path

For automotive use, review TDK's CGA3E3X7S2A104KT0Y0N, but validate the X7S dielectric. For non-automotive use, several general-purpose parts are strong parametric matches.

Main risk

Replacing an automotive-grade capacitor with a general-purpose one, potentially impacting reliability and safety in harsh environments.

Recommended alternatives

Matches key electricals and package, but is not automotive-grade. Review required.
