• Digital signs
• Scoreboards

Procurement Notes

Verify the specific suffix CU0W0351 against official Cree LED documentation to confirm binning and packaging details, as variations exist within the C566D family. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the procurement channel is an authorized partner to guarantee component authenticity and traceability. Check for any recent Product Change Notifications (PCN) that may affect specifications or manufacturing locations.

Selection Notes

Select this component when a standard 5mm oval footprint is required but higher durability is needed due to the extended lens profile. The 470nm blue emission and 2412mcd intensity make it suitable for high-visibility outdoor or indoor signage. Verify that the 70° x 30° viewing angle aligns with the optical design requirements of the target application. Ensure the operating temperature range meets the environmental conditions of the installation site.

Part Context

This part belongs to the C566D Series, which is part of Cree LED's Screen Master portfolio designed for video screens and signage. The series emphasizes reliability and optical performance for high-brightness applications. The C566D family includes various lens shapes and colors, with the BFF suffix typically indicating a blue diffused lens configuration in this context.

Replacement Considerations

The datasheet notes drop-in compatibility with competing 70/30 oval LEDs. Specific substitute part numbers are not provided in the available public documentation; verify mechanical fit and electrical parameters with alternative manufacturers before substitution.
