Is there a pin-compatible replacement for TCC0402X7R154K250AT?

Yes, several parts like Yageo's CC0402KRX5R8BB154 are pin-compatible in the 0402 package, but they have different electrical characteristics (e.g., dielectric type) that must be reviewed.

What risks should I check before replacing TCC0402X7R154K250AT?

Key risks include changes in dielectric (X7R vs. X5R), which impacts temperature performance, and differences in capacitance value. Always verify the substitute meets your circuit's voltage, temperature, and capacitance requirements.

AI replacement insight

Electrical riskmedium

Candidates have different dielectrics or capacitance.

Package risklow

All viable candidates share the same 0402 package.

Can it be replaced directly?

No direct, fully-equivalent replacement was identified. Candidates require review for either dielectric type or capacitance value differences.

Best replacement path

The best path is finding a 150nF, 25V (or higher), X7R, ±10% (or tighter) capacitor in an 0402 package. No direct drop-in was found in this batch.

Main risk

The main risks are using a part with a different dielectric (e.g., X5R), which affects temperature stability, or a lower capacitance value, which can impact circuit performance.

Recommended alternatives

A 0.15µF 25V 0402 capacitor with an X5R dielectric that limits its max operating temperature compared to the target's X7R.
