• High brightness output suitable for transportation signage
• Through-hole construction for robust mechanical installation

Applications

• Variable-message signs
• Passenger-information signs
• Transportation signage

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock new units. Verify current supply status carefully before design finalization. Consider immediate qualification of replacement parts due to discontinuation risks.

Selection Notes

Select this part only if oval beam geometry is required for specific sign visibility. Ensure circuit design supports 20 mA forward current and 3.4 V drop. Confirm thermal management meets the +85°C maximum operating limit. Evaluate obsolescence impact on long-term production viability.

Part Context

Part of the Screen Master 5-mm Oval LED family, engineered for high-visibility applications. The C566C series utilizes specific lens shaping to direct light efficiently. This model represents a legacy through-hole solution prior to widespread surface-mount adoption in signage sectors.

Replacement Considerations

Direct substitutes include C566D-series variants. Verify pin compatibility and optical intensity requirements when transitioning to alternative part numbers from the same manufacturer family.
