C503B-RBS-CW0Z0AA2

Overview

The C503B-RBS-CW0Z0AA2 is a red, through-hole LED from the Cree C503B series. It features a 5mm round lens with a 23-degree viewing angle and a clear, colorless epoxy cover. The component emits at a dominant wavelength of 624nm with a typical forward voltage of 2.1V at a 20mA test current. Luminous intensity ranges from 3000 to 12000 mcd. It has a maximum power dissipation of 130mW and complies with RoHS standards.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior high-temperature and high-moisture resistance for outdoor durability.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure, ensuring stable light output over the component's life.
• Designed for excellent readability in demanding outdoor sign and signal applications.

Applications

• Electronic Signs & Signals (ESS)
• Motorway Signs
• Variable-Message Sign (VMS)
• Advertising 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 T-1 3/4 mounting holes. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into regulated assemblies.

Selection Notes

Select this component when a 23-degree beam angle is required for red indicator applications. Consider the 2.1V forward voltage drop for circuit design. Evaluate the 130mW power dissipation limit against thermal constraints. Compare against other C503B variants like RAS or RCS if different viewing angles are needed.

Part Context

This part belongs to the Cree C503B family of 5mm round LEDs. The 'R' indicates red color, 'BS' denotes the 23-degree viewing angle variant, and 'CW0Z0AA2' specifies the intensity bin and packaging details. This family is engineered for robust performance in harsh environments where long-term stability is critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other 5mm red LEDs having similar 23-degree angles and 2.1V forward voltage if necessary.
