C503B-RAS-CZ0C0AA2

Overview

The C503B-RAS-CZ0C0AA2 is a red light-emitting diode from the Cree LED C503B series. It features a 5 mm (T-1 3/4) round package with two leads for through-hole mounting. The device emits red light at a typical dominant wavelength of 624 nm. It offers a narrow viewing angle of 15 degrees and provides high luminous intensity ranging from 5860 to 23500 mcd. The component utilizes advanced optical-grade epoxy encapsulation for durability.

Feature Summary

• Constructed with advanced optical-grade epoxy resin containing UV inhibitors for superior resistance to high temperatures, moisture, and long-term sunlight exposure.
• Designed with a 15-degree viewing angle to provide concentrated light output suitable for applications requiring excellent readability.
• Features a standard 5 mm round form factor with a clear lens, ensuring stable light output over the operational life of the LED.

Applications

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

Procurement Notes

Verify the specific suffix CZ0C0AA2 against official Cree documentation to confirm exact binning parameters such as forward voltage and luminous intensity ranges. Ensure the procurement channel sources genuine components to maintain the specified optical-grade epoxy performance characteristics required for outdoor environmental stability.

Selection Notes

Select this component when a narrow beam spread is required for outdoor signage visibility. The 15-degree viewing angle concentrates light effectively compared to wider-angle alternatives. Confirm that the 5 mm through-hole package fits the mechanical constraints of the target PCB design and that the red color spectrum meets the regulatory requirements for the intended signaling application.

Part Context

This part belongs to the C503B family of 5-mm Red and Amber Round LEDs. The RAS designation specifically indicates the red color variant within the 15-degree viewing angle sub-series. This family is engineered for harsh environments, distinguishing itself through enhanced encapsulation materials that prevent degradation under direct sunlight and extreme weather conditions common in outdoor infrastructure.

Replacement Considerations

Compatible substitutes include other C503B-RAN or C503B-RCS variants if different intensity bins or viewing angles are acceptable. Verify pin compatibility and electrical ratings before substitution. Generic 5mm LEDs may lack the required UV-resistant epoxy properties necessary for the specified outdoor applications.
