CL21B474KBFNNNF Equivalent & Substitute Parts

Part Overview

The CL21B474KBFNNNF is a 0.47 µF ±10% 50V ceramic capacitor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package with X7R temperature coefficient. This multilayer ceramic capacitor (MLCC) is designed for general-purpose applications and operates across the temperature range of -55°C to 125°C. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when upgraded specifications such as tighter tolerances or automotive-grade ratings are needed for specific applications.
