Procurement Notes

This specific part number is officially listed as obsolete and no longer manufactured by Cree LED. Verification of availability should focus on identifying valid substitute components or alternative part numbers that maintain compatibility with existing designs. Buyers must confirm current stock status and lead times with authorized distributors, as direct procurement from the manufacturer is not possible for this discontinued item.

Selection Notes

Engineers selecting this component should note its discontinuation status. Selection criteria must prioritize compatible replacements that match the 5-mm oval form factor and radial pin spacing. Verify that substitute LEDs meet the required 527 nm wavelength and 5200 mcd intensity specifications to ensure consistent visual performance in signage applications without redesigning the mechanical housing.

Part Context

The C566C-GFF-CW0X0781 belongs to the Screen Master 5-mm Oval LED family, which includes variants like C566C-RFF and C566C-BFS. These LEDs are engineered for robust outdoor signal environments using high-temperature resistant materials. The family provides specialized beam angles suitable for message boards and digital signs, distinguishing them from standard indicator LEDs through their specific optical shaping and durability features.

Replacement Considerations

Official substitutes for the C566C-GFF-CW0X0781 are available through Cree LED's product line. Users should consult manufacturer documentation for cross-reference data to identify equivalent green oval LEDs that preserve the 5-mm footprint and electrical characteristics required for drop-in replacement scenarios.
