Is there a pin-compatible replacement for CC0603KRX7R7BB684?

Several parts share the 0603 package, making them physically compatible. However, no candidates were found with identical key electrical parameters. All reviewed options require engineering validation before substitution.

What risks should I check before replacing CC0603KRX7R7BB684?

Key risks include changes in capacitance value, dielectric material (e.g., X7R vs. X5R), and voltage rating. These can affect filtering, timing, and overall circuit stability. Also, check the lifecycle status to avoid NRND parts.

AI replacement insight

Electrical riskmedium

Changes in capacitance or dielectric affect circuit behavior.

Package risklow

Many alternatives exist in the standard 0603 package.

Sourcing riskmedium

Some alternatives may be NRND or have different supply chain availability.

Can it be replaced directly?

No direct drop-in replacement was found without caveats. All potential substitutes have different capacitance or dielectric properties that require engineering review.

Best replacement path

Search for 0603 MLCCs with 0.68µF capacitance, X7R dielectric, and a voltage rating of 16V or higher from other major manufacturers.

Main risk

The main risks are substituting with incorrect capacitance or a less stable dielectric (like X5R), which can impact circuit performance and reliability.

Recommended alternatives

A 0.68µF 50V capacitor in the same 0603 package, but with an X5R dielectric and NRND status, requiring careful review.
