C566D-BFF-CU34Q3S1

Overview

The C566D-BFF-CU34Q3S1 is a single-color blue LED from the Screen Master series by Cree LED. It features a diffused oval lens with dimensions of 5.20mm x 4.60mm and a maximum height of 11.90mm. The component emits light at a primary wavelength of 470nm with a typical forward voltage of 3.4V at a test current of 20mA. It offers a luminous intensity of 2042mcd and a viewing angle of 70° x 30°. Designed for through-hole radial mounting, it operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Features a diffused blue tinted oval dome lens for wide-angle light distribution
• Provides high luminous intensity suitable for indicator applications
• Supports standard through-hole radial mounting for easy PCB integration

Applications

• Panel indicators
• Status signaling
• Control equipment displays

Procurement Notes

Verify the specific suffix 'CU34' against official datasheets to confirm optical binning and intensity class. Ensure compatibility with existing thermal management designs given the 3.4V forward voltage. Confirm package availability as supply status may vary. Cross-reference replacement part numbers if discontinuation is suspected.

Selection Notes

Select this component when a high-intensity blue indicator is required in a standard 5mm oval form factor. Consider the 70° x 30° viewing angle for visibility requirements. Evaluate the 3.4V forward voltage drop against available drive circuitry. Ensure the through-hole radial package fits the mechanical constraints of the target enclosure.

Part Context

This part belongs to the Screen Master series, designed for general-purpose indication. It utilizes a standard T-1 3/4 (5mm) equivalent footprint but with an oval shape. The component is distinct from surface-mount variants and focuses on robust through-hole performance for industrial and consumer electronics.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include C566D-BFF-CU14Q3S2 and C566D-BFF-CU14Q4S1. Verify electrical and mechanical compatibility before substitution.
