Is there a pin-compatible replacement for CC0805JRX7R9BB122?

Yes, several parts like CC0805KRX7RABB102 are pin-compatible in the same 0805 package. While they fit physically, their electrical parameters (capacitance, tolerance) differ, so they are not drop-in functional replacements for all applications.

What risks should I check before replacing CC0805JRX7R9BB122?

Before replacing, you must verify if your circuit can tolerate a ~17% lower capacitance value and a wider ±10% tolerance. This is critical for timing, filtering, or tuning applications where precision is important.

CC0805JRX7R9BB122 Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo CC0805JRX7R9BB122, a 1.2nF 50V 5% 0805 capacitor, involves trade-offs. While several form-fit compatible options exist, they typically have slightly different capacitance and tolerance values that require careful engineering review.

AI replacement insight

Electrical riskmedium

Lower capacitance (-17%) and weaker tolerance (±10% vs ±5%) require circuit analysis.

Package risklow

All viable candidates share the same 0805 package, ensuring physical compatibility.

Can it be replaced directly?

No direct, drop-in replacement with identical key parameters was found. All viable alternatives require a trade-off, primarily a looser tolerance and slightly lower capacitance.

Best replacement path

Use a 1.0nF, 10% tolerance capacitor with a higher voltage rating, like CC0805KRX7RABB102, but verify its impact on circuit performance.

Main risk

The primary risk is the combination of lower capacitance and wider tolerance, which can affect the performance of timing circuits, filters, and oscillators.

Recommended alternatives

A form-fit compatible capacitor with higher voltage but lower capacitance and wider tolerance.
