C503B-RCN-CW0X0AA2

Overview

The C503B-RCN-CW0X0AA2 is a single-color red LED from the C503B family, manufactured by Cree LED. It features a 5mm round radial through-hole package with a clear dome lens. The component emits light at a dominant wavelength of 624nm. Typical forward voltage is 2.1V at a test current of 20mA. Luminous intensity ranges from 3000 to 12000 mcd, with a viewing angle of 30 degrees. Maximum height is 10.30mm.

Feature Summary

• Constructed with advanced optical-grade epoxy for superior high-temperature and high-moisture resistance.
• Encapsulation resin contains UV inhibitors to minimize degradation from long-term direct sunlight exposure.
• Provides stable light output over the operational life of the device in outdoor environments.

Applications

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

Procurement Notes

Verify the specific suffix CW0X0AA2 against official Cree LED documentation to confirm exact luminous intensity binning and packaging configuration. Ensure compatibility with existing PCB footprints for 5mm radial components. Confirm RoHS compliance status via the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high visibility in bright ambient conditions due to its UV-resistant construction. The 30-degree viewing angle offers a balance between beam spread and intensity suitable for signage. Ensure circuit design accommodates the 2.1V forward voltage drop at standard operating currents.

Part Context

This part belongs to the C503B series of 5mm round LEDs designed for harsh outdoor environments. The series utilizes specialized encapsulation materials to ensure durability against environmental stressors such as moisture and UV radiation, making it distinct from standard indoor indicator LEDs.

Replacement Considerations

Cross-reference with other C503B-RCN variants for different intensity bins or packaging options. Verify mechanical dimensions and electrical characteristics against alternative 5mm radial red LEDs if sourcing constraints require substitution.
