What risks should I check before replacing CL05C821JB5NNNC?

The main risk is using a capacitor with a different dielectric, like X7R instead of C0G/NP0. This can affect performance in timing, filtering, or RF circuits.

CL05C821JB5NNNC Alternatives, Datasheet & Cross Reference | Samsung Electro-Mechanics

Finding a substitute for the Samsung CL05C821JB5NNNC 820pF 50V 0402 capacitor involves matching its C0G/NP0 dielectric for stability. Several pin-compatible options exist.

AI replacement insight

Electrical riskhigh

High if dielectric type is mismatched (e.g., X7R); low if C0G/NP0 is matched.

Package risklow

The 0402 package is standardized, making physical replacement straightforward.

Can it be replaced directly?

Direct replacement for CL05C821JB5NNNC should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Prioritize candidates with C0G/NP0 dielectric, 50V rating, and ±5% tolerance in an 0402 package, such as those from Yageo or HRE.

Main risk

Substituting with a Class 2 dielectric (e.g., X7R) instead of the specified Class 1 (C0G/NP0) is the primary risk.

Recommended alternatives

Strong alternative from Yageo with matching package, capacitance, voltage, tolerance, and NP0 dielectric.
