Procurement Notes

This specific part number is discontinued and no longer produced by the manufacturer. Verification of availability should focus on identifying valid substitute components or checking remaining stock from authorized distributors. Procurement strategies must account for end-of-life status, ensuring that replacement parts meet identical electrical and mechanical specifications to maintain system compatibility without requiring redesign.

Selection Notes

Selection of this component requires consideration of its discontinuation status. Designers should evaluate alternative models within the same Screen Master family that offer compatible form factors and optical characteristics. Key selection criteria include matching the forward voltage, current requirements, and physical dimensions to ensure seamless integration into existing PCB layouts while maintaining the required brightness and viewing angle specifications for the intended application environment.

Part Context

The C566C-GFE-CY0Z0891 belongs to the Cree Screen Master 5-mm Oval LED series, which includes variants such as C566C-RFF, GFF, BFF, and AFF. This family is engineered for high visibility in outdoor environments, utilizing a distinct oval shape to provide wide horizontal viewing angles. The product line emphasizes durability and performance under varying temperature conditions, serving as a standard solution for large-scale display and information signage systems.

Replacement Considerations

Public confirmed substitute part numbers include C566D-GFE-CX0Z0791. Users should verify that any replacement maintains the same 5mm oval footprint, through-hole configuration, and green spectral output to ensure functional equivalence in existing assemblies.
