Is there a pin-compatible replacement for TCC0805X7R684K500DT?

Yes, many 0805 package capacitors are pin-compatible. However, an exact 0.68µF match is uncommon. Alternatives like the Samsung CL21B105KBFNNNE (1.0µF) are form-fit compatible but require electrical review.

What risks should I check before replacing TCC0805X7R684K500DT?

The main risk is the capacitance change. Using a 1.0µF part may alter circuit timing or filtering response. Using a lower value like 0.47µF can cause instability. Always verify performance in your specific application.

TCC0805X7R684K500DT Alternatives, Datasheet & Cross Reference | CCTC

Finding a substitute for the CCTC TCC0805X7R684K500DT 0.68µF 50V 0805 capacitor involves balancing capacitance, voltage, and tolerance. Alternatives often have standard 1.0µF or 0.47µF values, requiring engineering review.

AI replacement insight

Electrical riskmedium

Capacitance value differs from target, requiring design validation.

Package risklow

All viable alternatives share the same 0805 package.

Can it be replaced directly?

No, a direct drop-in replacement with identical 0.68µF capacitance is not commonly available. Functional alternatives with 1.0µF capacitance are the most viable path.

Best replacement path

Use a 1.0µF, 50V (or higher), ±10% X7R capacitor in an 0805 package from a major brand like Murata or Samsung, after validating circuit performance.

Main risk

The primary risk is the capacitance mismatch. Using a higher value (1.0µF) can alter filter characteristics or timing, while a lower value can cause instability.

Recommended alternatives

Functional alternative from a different vendor with higher capacitance.
