Is there a pin-compatible replacement for CC0603KRX7R8BB684?

Yes, several capacitors share the 0603 package. However, a true drop-in replacement requires matching electricals. CGA3E3X5R1H684KT0Y0N is pin-compatible but has a different dielectric (X5R vs X7R), affecting temperature performance.

What risks should I check before replacing CC0603KRX7R8BB684?

When replacing this capacitor, verify the substitute's dielectric (X7R is preferred), capacitance value, and voltage rating. A different dielectric like X5R will lower the max operating temperature. A different capacitance will affect circuit performance.

AI replacement insight

Electrical riskmedium

Capacitance or dielectric mismatch requires circuit analysis.

Package risklow

All viable candidates use the same 0603 package.

Sourcing risklow

The target and alternatives are common MLCCs.

Can it be replaced directly?

No direct, one-to-one replacement with identical key parameters was found. All viable options require some level of engineering review.

Best replacement path

For applications below 85°C, consider an X5R part with matching capacitance like CGA3E3X5R1H684KT0Y0N. Otherwise, evaluate functional alternates with higher capacitance.

Main risk

The primary risks are a reduced operating temperature range (switching to an X5R dielectric) or altered circuit behavior from a different capacitance value.

Recommended alternatives

A 680nF 50V capacitor in the same 0603 package, but with a more limited X5R temperature range.
