C566D-BFE-CU14Q4S1

Overview

The C566D-BFE-CU14Q4S1 is a single-color blue LED from the Screen Master series by Cree LED. It features a 470 nm peak wavelength and emits blue light with a tinted lens. The component utilizes a through-hole radial T-1 3/4 (5 mm) oval dome package measuring 5.2 mm x 4.6 mm. Electrical characteristics include a forward voltage of 3.4 V at a test current of 20 mA, with a power rating of 140 mW. It offers a luminous intensity of 2300 mcd and a viewing angle of 70° x 30°. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Emits blue light at a 470 nm wavelength for clear visual indication
• Features a tinted oval dome lens for directional light distribution
• Designed for through-hole mounting in standard 5 mm packages

Applications

• Panel status indicators
• Control board signaling
• Equipment front panels

Procurement Notes

Verify the specific suffix CU14Q4S1 against official datasheets to confirm optical binning and lens tinting specifications. Ensure compatibility with existing through-hole assembly processes and thermal management requirements for the target operating environment.

Selection Notes

Select this component when a distinct blue indication is required with moderate intensity. Consider the 70° x 30° viewing angle for alignment needs. Verify that the 3.4 V forward voltage aligns with the driving circuit design and that the 140 mW power rating suits the application's thermal constraints.

Part Context

This part belongs to the C566D family of standard single-color LEDs. It shares the physical T-1 3/4 form factor with other variants but differs in optical output and lens treatment. The Screen Master branding indicates its suitability for high-visibility applications requiring reliable performance.

Replacement Considerations

C566D-BFF-CU14Q4S1 is listed as a parameter-equivalent alternative.
