Is there a pin-compatible replacement for TCC1206X7R684K500FT?

Yes, several capacitors in the same 1206 package are available, making them physically compatible. However, all identified candidates have different capacitance values, so they are not direct electrical drop-in replacements.

What risks should I check before replacing TCC1206X7R684K500FT?

The main risk is the capacitance mismatch. Using a higher capacitance (e.g., 1µF instead of 680nF) can affect timing circuits, filter characteristics, or cause inrush current issues. Always verify the impact on your specific application.

AI replacement insight

Electrical riskmedium

Capacitance differs, which can affect circuit behavior like filtering or timing.

Package risklow

All suggested alternatives share the same 1206 package.

Sourcing risklow

The suggested 1µF alternatives are common values from multiple manufacturers.

Can it be replaced directly?

No direct, one-to-one replacements with 680nF capacitance were found in this review. All suitable candidates require a parameter relaxation on capacitance.

Best replacement path

Use a 1µF, 50V (or higher) X7R capacitor in a 1206 package, such as TCC1206X7R105K500HT, after verifying your circuit can tolerate the increased capacitance.

Main risk

The primary risk is functional change due to different capacitance values. Using a lower value is not recommended; using a higher value requires circuit analysis.

Recommended alternatives

A 1206 cap with higher voltage (100V) and higher capacitance (1µF). Requires engineering review.
