C566C-RFN-CU0W0BB2

Overview

The C566C-RFN-CU0W0BB2 is a single-color red LED from the Cree Screen Master family, designed for through-hole mounting in a T-1 3/4 (5 mm) oval package. It emits light at a wavelength of 621 nm with a typical forward voltage of 2.1 V at a test current of 20 mA. The component features a diffused red lens with dimensions of 5.20 mm x 4.60 mm and a height of 7.80 mm. Optical performance includes a viewing angle of 70° x 35° and an intensity of 2850 mcd. It operates within a temperature range of -40°C to +95°C and has a power rating of 130 mW.

Feature Summary

• Oval dome lens design providing a 70° x 35° viewing angle
• Through-hole radial mount construction in a standard 5 mm form factor
• Diffused red lens for uniform light distribution
• Compatible with standard logic circuit voltages

Applications

• Panel indicator lights
• Control station status displays
• Instrumentation visual signaling

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Cree LED documentation. Confirm that the specific suffix matches the required optical and electrical characteristics. Ensure handling procedures account for the through-hole package type during assembly. Check for any specific environmental compliance certifications required for the target application.

Selection Notes

Select this component when a standard 5 mm oval red indicator is required for panel mounting. The diffused lens offers wide visibility angles suitable for general status indication. Consider the 2.1 V forward voltage drop for series resistor calculations in drive circuits. Verify thermal management requirements against the maximum operating temperature limit of +95°C.

Part Context

This part belongs to the C566C Screen Master family of 5 mm oval LEDs. The family includes variants with different lens colors and diffusion types. The C566C-RFN specifically denotes the red diffused version. These components are widely used in industrial and consumer electronics for reliable visual feedback.

Replacement Considerations

Direct substitutes include other manufacturers' 5 mm oval red diffused LEDs with similar forward voltage and current ratings. Verify mechanical footprint compatibility, specifically the lead spacing and overall height. Ensure optical intensity and viewing angle meet the application's visibility requirements.
