C566C-BFE-CT0U0451

Overview

The C566C-BFE-CT0U0451 is a single-color blue LED from the Cree Screen Master series, designed for through-hole mounting in a T-1 3/4 (5 mm) oval package. It features a dominant wavelength of 470 nm and a forward voltage of 3.4 V at a test current of 20 mA. The component delivers a luminous intensity of 1500 mcd with a power rating of 140 mW. Its viewing angles are specified as 70 degrees horizontally and 35 degrees vertically. The lens is clear and tinted, measuring 5.2 mm by 4.6 mm, with an overall height of 7.8 mm. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Oval-shaped radiation pattern optimized for variable-message signs
• High-intensity blue emission suitable for passenger-information displays
• Through-hole construction for robust mechanical integration

Applications

• Variable-message signs
• Passenger-information signs
• Public transit display systems

Procurement Notes

Verify the specific suffix CT0U0451 against the manufacturer datasheet to confirm active status and exact optical characteristics. Ensure compatibility with existing through-hole assembly processes. Check for RoHS compliance details in the official documentation before finalizing procurement decisions.

Selection Notes

Select this component when high-brightness blue indication is required for large-format signage applications. The oval shape provides distinct horizontal visibility compared to standard round LEDs. Consider the 3.4 V forward voltage drop for circuit design. Verify that the 70-degree horizontal viewing angle meets the line-of-sight requirements of the installation environment.

Part Context

This part belongs to the C566C-RFE/C566C-BFE family of Screen Master LEDs. These components are engineered specifically for outdoor and indoor digital signage environments where high brightness and wide viewing angles are critical. The series replaces older oval LED technologies with improved efficiency and color consistency.

Replacement Considerations

Cross-reference with C566D-BFE-CU0W0351 for potential functional equivalents. Verify pinout and dimensional tolerances before substitution. Confirm that the replacement part maintains the same 470 nm wavelength and 1500 mcd intensity levels.
