C503B-AAS-FZ0A0341

Overview

The C503B-AAS-FZ0A0341 is a 5-mm amber round LED from the Cree C503B family, designed for high-visibility outdoor applications. It features a 15-degree viewing angle and utilizes optical-grade epoxy with UV inhibitors for superior high-temperature and moisture resistance. The component emits at a typical dominant wavelength of 591 nm, offering luminous intensity ranging from 5860 to 23500 mcd. Constructed with lead-free RoHS-compliant materials, it ensures stable light output over its operational life despite direct sunlight exposure.

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.
• Stable light output performance maintained throughout the operational life of the LED in harsh environments.

Applications

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

Procurement Notes

Verify the specific suffix FZ0A0341 against official Cree documentation to confirm exact binning parameters and packaging configuration. Ensure compatibility with existing circuit designs regarding forward voltage and current requirements. Confirm availability status as distribution channels may list obsolete or discontinued variants within this product family.

Selection Notes

Select this component when a narrow 15-degree beam angle is required for focused visibility in outdoor signage. The amber color variant is suitable for warning signals or specific traffic control applications. Consider the robust environmental sealing provided by the epoxy lens for installations exposed to extreme weather conditions.

Part Context

This part belongs to the C503B series of 5-mm round LEDs manufactured by Cree LED. The series includes red and amber variants with varying viewing angles (15, 23, and 30 degrees). These components are engineered specifically for readability in demanding outdoor sign and signal applications, distinguishing them from general-purpose indicator LEDs.

Replacement Considerations

Cross-reference with other C503B suffixes such as AAN or ABS if different intensity bins or packaging types are needed. Verify mechanical footprint compatibility with existing PCB layouts. Check for updated datasheets to ensure no functional changes have been made to the base C503B architecture.
