Is there a pin-compatible replacement for CL31B225KAHNNNE?

Yes, candidates with a 1206 package, 2.2µF capacitance, and X7R dielectric are considered pin-compatible. Always verify the datasheet for exact dimensions and electrical characteristics before production.

What risks should I check before replacing CL31B225KAHNNNE?

Verify the replacement has the same package (1206), capacitance (2.2µF), and dielectric (X7R). Ensure the voltage rating is 25V or higher. Also check secondary parameters like ESR if critical for your application.

CL31B225KAHNNNE Alternatives, Datasheet & Cross Reference | Samsung Electro-Mechanics

The Samsung CL31B225KAHNNNE is a common 2.2µF, 25V, 1206 X7R ceramic capacitor. Several alternatives with matching or upgraded voltage ratings are available from other manufacturers.

AI replacement insight

Electrical risklow

Low if voltage is >= 25V and dielectric is X7R.

Package riskhigh

High if the package is not 1206.

Sourcing risklow

This is a very common capacitor value and size.

Can it be replaced directly?

Yes, several manufacturers offer 2.2µF, 1206 X7R capacitors that are potential pin-compatible replacements, often with higher voltage ratings.

Best replacement path

Use an alternative with a 1206 package, 2.2µF capacitance, and a voltage of 25V or higher, like Taiyo Yuden's HMK316AC7225KLHTE (100V).

Main risk

The main risks are package size mismatches or different dielectric characteristics (e.g., X7S vs. X7R), which require design changes.

Recommended alternatives

Pin-compatible, automotive-grade upgrade with a higher 50V rating.
