Is there a pin-compatible replacement for TCC0805X7R103K251DT?

Yes, TCC0805X7R103K501DTS is a pin-compatible replacement. It has the same 0805 package, 10nF capacitance, and X7R dielectric, but with a higher 500V rating.

What risks should I check before replacing TCC0805X7R103K251DT?

Always verify the package size (0805), capacitance (10nF), and dielectric (X7R). Avoid parts with different packages (like 1206) or different dielectrics (like C0G or Y5V) unless you can redesign the PCB or re-validate circuit performance.

AI replacement insight

Package riskhigh

Several candidates have different package sizes (1206, 1812) and are not drop-in replacements.

Electrical riskmedium

One candidate has a C0G dielectric instead of X7R, which changes performance characteristics.

Can it be replaced directly?

Yes, TCC0805X7R103K501DTS is a pin-compatible upgrade with a higher voltage rating.

Best replacement path

Upgrade to the 500V version from the same manufacturer, TCC0805X7R103K501DTS, for a direct, pin-compatible fit with increased voltage margin.

Main risk

The main risks are using a part with a different package size (e.g., 1206) or a different dielectric material (e.g., C0G), which require board redesign or circuit re-evaluation.

Recommended alternatives

A form-fit-function compatible upgrade from the same manufacturer with a higher 500V voltage rating.
