C566C-AFF-CU0W0251

Overview

The C566C-AFF-CU0W0251 is a single-color amber LED from the Screen Master series by Cree LED. It utilizes a T-1 3/4 (5 mm) radial through-hole package with dimensions of 5.20 mm x 4.60 mm and a maximum height of 11.90 mm. The component emits light at a primary wavelength of 591 nm with a typical forward voltage of 2.1 V at a test current of 20 mA. It features an oval dome lens with diffused transparency, providing a viewing angle of 70° x 35°. The optical intensity is rated at 2850 mcd, and it operates within a temperature range of -40°C to +95°C.

Feature Summary

• Features a diffused oval dome lens for wide-angle light distribution
• Designed for standard through-hole mounting applications
• Provides high-intensity amber illumination with specific spectral characteristics

Applications

• Panel indicator lights
• Status signaling in electronic equipment
• Instrumentation displays

Procurement Notes

Verify the exact suffix configuration when ordering, as variations such as CU0W0252 exist with identical electrical parameters but different packaging or minor specification details. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before finalizing procurement orders to ensure supply chain compatibility.

Selection Notes

Select this component for designs requiring a 5 mm through-hole form factor with high luminous intensity. The 2.1 V forward voltage allows for direct driving from standard logic levels without excessive current limiting resistance compared to higher voltage alternatives. Ensure mechanical clearance accommodates the 11.90 mm maximum height constraint.

Part Context

This part belongs to the C566C family of Screen Master LEDs, which are characterized by their robust construction and consistent optical performance. The AFF suffix denotes the specific amber color variant within this series, distinguishing it from red, green, or blue options that share similar physical footprints but differ in wavelength and forward voltage requirements.

Replacement Considerations

C566C-AFF-CU0W0252 is listed as a parameter-equivalent substitute.
