Is there a pin-compatible replacement for CC0805KRX7R9BB331?

No, a fully pin-compatible replacement without caveats was not identified. While several candidates use the same 0805 package, they differ in key electrical parameters like capacitance or dielectric type, requiring engineering validation before substitution.

What risks should I check before replacing CC0805KRX7R9BB331?

Before replacing, you must verify your circuit's tolerance for a different capacitance value (e.g., 470pF instead of 330pF) or a different dielectric type (stable NP0 vs. general-purpose X7R). Also, check for physical package mismatches (0402 vs. 0805).

CC0805KRX7R9BB331 Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo CC0805KRX7R9BB331, a 330pF 50V 0805 X7R capacitor, requires careful review. While alternatives exist, they often present trade-offs in capacitance, dielectric material, or package size that need engineering validation.

AI replacement insight

Electrical riskhigh

Capacitance or dielectric mismatches can significantly alter filter, timing, or coupling behavior.

Package riskhigh

One candidate has a smaller 0402 package, which is not physically compatible with the 0805 footprint.

Can it be replaced directly?

There are no direct, fully-equivalent replacements for CC0805KRX7R9BB331 in this list. All candidates require engineering review due to differences in capacitance, dielectric type, or package size.

Best replacement path

No direct drop-in replacement was found. If higher capacitance is acceptable, CC0805KRX7R9BB471 is an option. If a more stable dielectric is needed, CC0805JRNPO0BN331 is a functional upgrade.

Main risk

The primary risks are circuit malfunction from incorrect capacitance (470pF vs 330pF) or a change in performance due to a different dielectric material (NP0 vs X7R).

Recommended alternatives

Same package and capacitance, but different dielectric (NP0 vs X7R) requires engineering review. Voltage is higher.
