C503B-RAS-CZ0C0AA1

Overview

The C503B-RAS-CZ0C0AA1 is a red single-color LED from the Cree LED family, housed in a 5 mm (T-1 3/4) through-hole package. It features a round lens shape with a clear surface and colorless appearance. The component operates at a typical dominant wavelength of 624 nm and provides a luminous intensity range of 5860 to 23500 mcd. It has a narrow viewing angle of 15 degrees, making it suitable for focused light applications.

Feature Summary

• Advanced optical-grade epoxy encapsulation ensures superior high-temperature and high-moisture resistance performance.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Provides stable light output over the operational life of the LED in demanding outdoor environments.

Applications

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

Procurement Notes

Verify the specific suffix CZ0C0AA1 against official Cree documentation to confirm exact binning parameters such as forward voltage and intensity class. Ensure compatibility with existing PCB layouts for the 5 mm T-1 3/4 package. Confirm RoHS compliance status via the manufacturer datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a narrow 15-degree beam angle is required for precise signal visibility. The red color and high-intensity output are optimized for outdoor readability. Consider the thermal management capabilities of the optical-grade epoxy if operating in high-ambient temperature conditions.

Part Context

This part belongs to the C503B series of 5-mm Red and Amber Round LEDs designed for robust outdoor use. The RAS designation indicates the 15-degree viewing angle variant within the family. These lamps are engineered for excellent readability in harsh environmental conditions using advanced encapsulation materials.

Replacement Considerations

Consult the official C503B datasheet for cross-referencing other variants within the same family that share identical package dimensions and electrical characteristics but differ in viewing angles or intensity bins.
