C566D-BFE-CU34Q4S1

Overview

The C566D-BFE-CU34Q4S1 is a single-color blue LED from the Screen Master series by Cree LED. It features a through-hole T-1 3/4 (5 mm) oval package with dimensions of 5.2 mm x 4.6 mm and a maximum height of 7.8 mm. The component emits light at a peak wavelength of 470 nm with a tinted lens. Electrical characteristics include a forward voltage of 3.4 V and a power rating of 140 mW at a test current of 20 mA. Optical performance specifies an intensity of 2300 mcd and a viewing angle of 70° x 30°. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Oval dome lens design for directional light emission
• Through-hole mounting for standard PCB integration
• High optical intensity output in blue spectrum

Applications

• Panel indicators
• Instrumentation displays
• Status signaling

Procurement Notes

Verify the specific suffix CU34Q4S1 against official datasheets to confirm binning and optical tolerances. Confirm RoHS compliance status as required by project specifications. Check for end-of-life notifications or product change notices that may affect long-term availability. Ensure packaging format matches production requirements.

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. Verify thermal management capabilities if operating near the upper temperature limit. Compare intensity bins against application brightness needs.

Part Context

This part belongs to the Screen Master family, designed for high-brightness indication applications. It utilizes a standard T-1 3/4 package common in legacy and modern panel designs. The blue color variant targets visual alerts where high contrast is necessary.

Replacement Considerations

Direct substitutes require matching the 5mm oval footprint, 470nm wavelength, and similar intensity levels. Verify pin compatibility and forward voltage tolerance before substitution.
