C503B-AAS-CA0C0341-015

Overview

The C503B-AAS-CA0C0341-015 is a 5-mm round amber LED from the Cree C503B family, designed for high-readability outdoor applications. It features a 15-degree viewing angle and utilizes advanced optical-grade epoxy with UV inhibitors for superior high-temperature and moisture resistance. The component operates at a typical dominant wavelength of 591 nm, delivering luminous intensity ranging from 5860 to 23500 mcd. It is lead-free and RoHS-compliant, ensuring stable light output over its operational life in demanding environments.

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 stable light output over the entire life of the LED for consistent readability.

Applications

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

Procurement Notes

Verify the specific suffix CA0C0341-015 against official Cree documentation to confirm exact binning and packaging details. Ensure compatibility with existing circuit designs regarding forward voltage and current requirements. Check for any obsolescence notices or recommended replacement parts if the specific variant is no longer actively manufactured.

Selection Notes

Select this component when high-intensity amber illumination with a narrow 15-degree beam is required for outdoor signage. Consider the robust environmental protection offered by the UV-inhibited epoxy for installations exposed to harsh weather conditions. Verify that the 5-mm form factor fits the mechanical constraints of the target application housing.

Part Context

This part belongs to the C503B series of 5-mm round LEDs, which includes red and amber variants with different viewing angles (15, 23, and 30 degrees). The AAS designation specifically indicates an amber color with a 15-degree viewing angle within this family, optimized for applications requiring focused light output.

Replacement Considerations

Consult official Cree documentation for direct substitutes within the C503B family, such as other amber variants with compatible viewing angles. Verify electrical parameters and mechanical dimensions before substituting with generic 5-mm amber LEDs to ensure performance consistency.
