C503B-RBS-CW0X0AA1

Overview

The C503B-RBS-CW0X0AA1 is a red round LED from the Cree LED series, housed in a 5 mm (T-1 3/4) package with two pins. It features a clear lens and operates at a forward voltage of 2.6 V. The device emits light at a dominant wavelength of 624 nm with a luminous intensity of 12 cd. It has a viewing angle of 23 degrees and a maximum power dissipation of 130 mW. The component supports through-hole installation and complies with RoHS standards.

Feature Summary

• Constructed with advanced optical-grade epoxy for superior high-temperature and high-moisture resistance.
• Encapsulation resin contains UV inhibitors to minimize effects of long-term direct sunlight exposure.
• Provides stable light output over the life of the LED for excellent readability in outdoor applications.

Applications

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

Procurement Notes

Verify the specific suffix CW0X0AA1 against official Cree datasheets to confirm exact binning and optical characteristics. Ensure compatibility with existing PCB layouts for 5 mm T-1 3/4 through-hole mounting. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into final products.

Selection Notes

Select this component for applications requiring high visibility in outdoor environments due to its UV-resistant encapsulation. The 23-degree viewing angle offers a balance between beam spread and intensity suitable for signage. Ensure drive circuits accommodate the 2.6 V forward voltage and 130 mW power dissipation limits for reliable operation.

Part Context

This part belongs to the Cree 5-mm Red and Amber Round LEDs family, specifically the RBS variant which denotes a 23-degree viewing angle. The series is designed for outdoor sign and signal applications where durability and consistent light output are critical. It shares the same physical footprint as other variants in the C503B series but differs in optical performance.

Replacement Considerations

Direct substitutes within the same family include C503B-RAS (15-degree) or C503B-RCS (30-degree) if viewing angle adjustments are acceptable. Cross-manufacturer replacements require matching the 5 mm T-1 3/4 package, 624 nm wavelength, and 2.6 V forward voltage specifications.
