Is there a pin-compatible replacement for CC0603FRNPO9BN820?

Yes, several parts share the same 0603 package, making them physically compatible. However, no identified part has the exact 82pF capacitance, so electrical function must be verified by an engineer before substitution.

What risks should I check before replacing CC0603FRNPO9BN820?

The main risk is the capacitance difference. The target is 82pF; alternatives may have 100pF or 120pF. This can affect timing, filtering, or impedance matching. Also check tolerance, as some alternatives are ±5% instead of ±1%.

CC0603FRNPO9BN820 Alternatives, Datasheet & Cross Reference | Yageo

Finding a substitute for the Yageo CC0603FRNPO9BN820 82pF 1% MLCC requires careful review of capacitance. While no exact drop-in is identified, several functional alternatives with the same package and ratings are available.

AI replacement insight

Electrical riskmedium

Capacitance and tolerance differences require engineering validation.

Package risklow

All suggested alternatives use the same 0603 package.

Can it be replaced directly?

No direct, one-to-one replacement with identical 82pF capacitance and ±1% tolerance is commonly available. The closest options have different capacitance values.

Best replacement path

Use an alternative with slightly higher capacitance like Yageo's AC0603FRNPO9BN101 (100pF) and verify circuit performance.

Main risk

The primary risk is functional deviation due to mismatched capacitance, which can alter circuit behavior in timing or filter applications.

Recommended alternatives

A form-fit compatible MLCC with higher capacitance (100pF) and automotive-grade qualification.
