C503B-GCS-CZ0A0781

Overview

The C503B-GCS-CZ0A0781 is a 5-mm green round LED from the Cree C503B series, designed for high-visibility outdoor applications. It features a 30-degree viewing angle and utilizes advanced optical-grade epoxy with UV inhibitors for superior high-temperature and moisture resistance. The component emits at a typical dominant wavelength of 527 nm, providing stable light output over its operational life. It is lead-free and RoHS-compliant, ensuring reliability in demanding environments such as electronic signs and signals.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and high moisture levels.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Ensures extremely stable light output over extended periods for dependable performance in outdoor conditions.

Applications

• Electronic Signs & Signals (ESS)
• Motorway Signs
• Variable-Message Sign (VMS)

Procurement Notes

Verify the specific suffix CZ0A0781 against official Cree documentation to confirm binning parameters and availability status. Ensure compatibility with existing PCB footprints and thermal management requirements for outdoor sign assemblies. Cross-reference datasheet revisions to confirm material compliance and manufacturing origin details prior to final procurement authorization.

Selection Notes

Select this component when a 30-degree viewing angle is required for broader dispersion compared to narrower beam options. Consider the 5-mm form factor for standard through-hole mounting configurations. Evaluate the green color option for high contrast visibility in daylight conditions. Confirm that the environmental sealing properties meet the specific exposure requirements of the target installation site.

Part Context

This part belongs to the C503B family of 5-mm round LEDs manufactured by Cree LED. The series includes red, amber, blue, and green variants with varying viewing angles of 15, 23, and 30 degrees. The GCS designation specifically indicates the green color variant with the 30-degree viewing angle configuration within this standardized product line.

Replacement Considerations

Direct substitutes include other C503B-GCN or C503B-GAS variants if viewing angle differences are acceptable. Verify mechanical dimensions and electrical characteristics against current inventory components to ensure functional equivalence without redesigning the host circuit board or enclosure.
