Is there a pin-compatible replacement for CL05B223KB5NNNC?

Not confirmed. Some candidates share 0402 and 2 terminals, but capacitance differs and PDFs were not checked.

What risks should I check before replacing CL05B223KB5NNNC?

Check capacitance value, DC bias, tolerance, voltage margin, temperature range, and whether the footprint matches 0402.

CL05B223KB5NNNC is a 22nF 50V X7R 0402 MLCC. Alternatives need package, capacitance, voltage, and tolerance review.

Kept 0402 parts change capacitance.

0603 and 1206 need layout review.

Passive MLCC has no firmware.

Some candidates lack checked PDFs or URLs.

No confirmed pin-compatible replacement is proven from the provided data.

Start with same 0402 X7R 50V parts only if the circuit can accept 27nF or 33nF.

Capacitance mismatch or footprint mismatch can change circuit behavior.

CCTC 27nF 0402 X7R is a value-relaxed alternative needing circuit review.

Package	0402	0402	-	-	0603 — board change likely
Pinout	2 nonpolar	2 nonpolar	-	-	2 nonpolar — same terminal count
Voltage	50V	50V	-	-	50V — same rating
Tolerance	±10%	±10%	-	-	±10% — same tolerance
Application	22nF X7R	27nF X7R	-	-	33nF X7R — 50% higher value

No exact verified alternative is shown. The closest same-footprint options are 27nF or 33nF 0402 X7R parts, requiring review.
