C503B-RBS-CW0Z0AA1

Overview

The C503B-RBS-CW0Z0AA1 is a red through-hole LED from the Cree series, housed in a 5 mm (T-1 3/4) package with two pins. It features a forward voltage of 4 V and a maximum power dissipation of 120 mW. The device emits light at a dominant wavelength of 624 nm with a viewing angle of 23 degrees. Luminous intensity ranges from 3000 to 12000 mcd. It utilizes an optical-grade epoxy lens for high-temperature and moisture resistance.

Feature Summary

• Constructed with advanced optical-grade epoxy for superior high-temperature and high-moisture resistance.
• Encapsulation resin includes UV inhibitors to minimize sunlight exposure effects and ensure stable light output.
• Designed for excellent readability in outdoor sign and signal applications.

Applications

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

Procurement Notes

Verify the specific suffix CW0Z0AA1 against official Cree documentation to confirm exact luminous intensity binning and wavelength tolerances. Ensure compatibility with standard 5 mm T-1 3/4 PCB footprints. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into regulated assemblies.

Selection Notes

Select this component when a 23-degree viewing angle is required for red indicator applications. Compare against C503B-RAS variants for narrower beams or C503B-RCS models for wider dispersion. Verify that the 4 V forward voltage aligns with the circuit's drive capability and thermal management requirements for continuous operation.

Part Context

This part belongs to the Cree C503B family of 5-mm round LEDs, which also includes green, blue, amber, and white variants. The family shares common mechanical dimensions and mounting styles but differs in semiconductor materials to achieve specific color outputs and electrical characteristics suitable for various signaling environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing requires consulting official Cree replacement guides or distributor equivalence databases for compatible 5 mm red LEDs with similar electrical parameters.
