C503B-RBN-CW0Z0AA2

Overview

The C503B-RBN-CW0Z0AA2 is a red, through-hole LED from the Cree C503B series. It features a 5mm round, clear lens with a 23-degree viewing angle. The device emits at a dominant wavelength of 624nm with a typical forward voltage of 2.1V at a test current of 20mA. Luminous intensity ranges from 3000 to 12000 mcd. Constructed with UV-inhibited optical-grade epoxy, it ensures stable light output and resistance to high temperature and moisture for outdoor durability.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior high-temperature and high-moisture resistance.
• Encapsulation resin contains UV inhibitors to minimize degradation from direct sunlight exposure.
• Ensures stable light output over the operational life of the component in harsh environments.

Applications

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

Procurement Notes

Verify the specific suffix CW0Z0AA2 against official Cree documentation to confirm exact luminous intensity binning and packaging configuration. Ensure compatibility with standard 5mm PCB layouts. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into final assemblies requiring environmental certifications.

Selection Notes

Select this component for applications requiring high visibility in outdoor signage due to its UV-resistant construction. The 23-degree beam angle offers a balance between focus and spread suitable for general signaling. Consider thermal management requirements based on the maximum power dissipation limits specified in the datasheet for continuous operation scenarios.

Part Context

This part belongs to the C503B family of 5mm Red and Amber Round LEDs designed for outdoor readability. The RBN variant specifically denotes the red color with a 23-degree viewing angle. These components are engineered for robust performance in electronic signs and traffic signals where long-term stability under environmental stress is critical.

Replacement Considerations

Cross-reference compatible parts within the C503B series such as C503B-RBS or C503B-RCS if different viewing angles are required. Verify that substitute components maintain identical mechanical dimensions and electrical characteristics to ensure fit and function without circuit modification.
