Is there a pin-compatible replacement for CC0805JRNPO9BN751?

Yes, several parts like CC0805JRNPO9BN681 are pin-compatible as they share the same 0805 package. However, they are not exact functional replacements due to differences in capacitance. You must verify if the lower capacitance is acceptable for your circuit.

What risks should I check before replacing CC0805JRNPO9BN751?

The primary risk is the change in capacitance. A lower value (e.g., 680pF instead of 750pF) can alter the performance of timing circuits, filters, or oscillators. Always verify the impact of this parametric difference on your circuit's behavior before committing to a substitute.

Finding a substitute for the Yageo CC0805JRNPO9BN751, a 750pF 50V 0805 NP0 capacitor, requires careful attention to capacitance. While form-fit alternatives are available, an exact capacitance match is uncommon, necessitating engineering review of parametric differences.

AI replacement insight

Electrical riskmedium

Capacitance difference requires validation to ensure circuit performance is not compromised.

Package risklow

All top candidates use the same 0805 package, ensuring form and fit compatibility.

Can it be replaced directly?

No exact direct replacement was found. The closest alternatives, like CC0805JRNPO9BN681, have a slightly lower capacitance of 680pF and require engineering review.

Best replacement path

CC0805JRNPO9BN681 is the best available alternative, offering identical package, voltage, and dielectric with only a ~9% lower capacitance.

Main risk

The main risk is capacitance mismatch. The target's 750pF value is not a standard E12/E24 value, making exact matches rare. Substitutes will likely have lower capacitance, which can affect timing, filtering, or resonance in sensitive circuits.

Recommended alternatives

A strong alternative with higher voltage rating (100V) and slightly lower capacitance (680pF).
