C566D-GFF-CY34Q8S1

Overview

The C566D-GFF-CY34Q8S1 is a single-color green LED from the Screen Master series by Cree LED. It features a T-1 3/4 (5 mm) oval lens with dimensions of 5.2 mm x 4.6 mm and a height of 7.8 mm. The component emits light at a wavelength of 527 nm with an optical intensity of 6300 mcd. Electrical characteristics include a forward voltage of 3.4 V and a power rating of 140 mW at a test current of 20 mA. It operates within a temperature range of -40°C to +85°C and utilizes through-hole mounting.

Feature Summary

• Features a tinted oval lens with clear transparency for standard indication applications.
• Designed for through-hole installation in a T-1 3/4 (5 mm) radial package.
• Provides high-intensity green emission optimized for visibility.

Applications

• Panel indicators
• Status signaling
• Control equipment displays

Procurement Notes

Verify the specific suffix CY34Q8S1 against official Cree LED documentation to confirm exact binning and packaging details. Ensure compatibility with existing thermal management designs, as the component has a 140 mW power rating. Confirm that the 527 nm wavelength meets the required color specifications for the target application before finalizing procurement.

Selection Notes

Select this component when a high-brightness green indicator is required in a standard 5 mm through-hole form factor. The 527 nm wavelength offers distinct visibility compared to standard yellow or red LEDs. Consider the 3.4 V forward voltage drop when designing the driving circuitry to ensure appropriate current limiting resistors are used for reliable operation at 20 mA.

Part Context

This part belongs to the C566D series, which is part of the Screen Master family of LEDs. These components are engineered for general-purpose indication where consistent color and intensity are critical. The series typically includes various colors and lens styles, with the C566D specifically denoting the green variant in the oval package configuration.

Replacement Considerations

C566D-GFF-CX14Q8S1 is listed as a parameter-equivalent alternative within the same manufacturer's portfolio. Verify electrical and mechanical compatibility before substitution.
