C503B-BAS-CX0B0461

Overview

The C503B-BAS-CX0B0461 is a 5-mm round single-color LED from the Cree LED C503B family, designed for through-hole mounting. It features an amber lens with a clear finish and a 15-degree viewing angle. The component utilizes advanced optical-grade epoxy encapsulation to ensure high-temperature and high-moisture resistance, providing stable light output over its operational life. It is RoHS compliant and lead-free.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for reliable outdoor performance.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Round lens design with a narrow 15-degree viewing angle concentrates light for enhanced readability in bright conditions.

Applications

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

Procurement Notes

Verify the specific suffix CX0B0461 against official Cree documentation to confirm exact binning or packaging variations. Confirm current availability status as distribution channels may list obsolete or discontinued variants. Ensure compatibility with existing through-hole assembly processes and verify RoHS compliance certificates match the manufacturing batch.

Selection Notes

Select this component when a narrow beam spread is required for long-distance visibility in signage applications. The 15-degree angle offers higher intensity concentration compared to wider beam alternatives. Ensure the design accommodates the 5-mm radial leaded package dimensions and thermal requirements for continuous operation in outdoor environments.

Part Context

This part belongs to the C503B series of 5-mm round LEDs manufactured by Cree LED. The series includes various colors and beam angles optimized for outdoor readability. The C503B-BAS variant specifically denotes the amber color option within the 15-degree beam configuration, distinguishing it from the 23-degree and 30-degree variants in the same family.

Replacement Considerations

Direct substitutes include other C503B-Axx models with identical 15-degree beam angles and 5-mm through-hole packages. Verify that alternative amber LEDs maintain comparable luminous intensity ranges and forward voltage characteristics to ensure circuit compatibility without redesign.
