C503B-RBS-CW0X0AA2

Overview

The C503B-RBS-CW0X0AA2 is a red light-emitting diode from the Cree LED family, designed for through-hole mounting in a 5mm (T-1 3/4) radial package. It features a clear, colorless lens with a circular dome shape and a viewing angle of 23 degrees. The component operates at a typical forward voltage of 2.1V with a dominant wavelength of 624nm. Luminous intensity ranges from 3000 to 12000 mcd under a 20mA test current. The encapsulation utilizes advanced optical-grade epoxy containing UV inhibitors for high temperature and moisture resistance.

Feature Summary

• Constructed with advanced optical-grade epoxy resin providing superior high-temperature and high-moisture resistance for outdoor durability.
• Encapsulation includes UV inhibitors to minimize degradation from direct sunlight exposure, ensuring stable light output over the product lifecycle.
• Features a 23-degree viewing angle suitable for applications requiring focused visibility and excellent readability.

Applications

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

Procurement Notes

Verify the specific suffix CW0X0AA2 against official Cree datasheets to confirm exact luminous intensity binning and packaging configuration. Ensure compatibility with standard 5mm through-hole PCB layouts. Confirm RoHS compliance status if required by local regulations. Cross-reference ordering codes with manufacturer documentation to avoid substitution errors.

Selection Notes

Select this component when a 23-degree beam angle is required for red indicator applications. The 5mm T-1 3/4 form factor ensures mechanical compatibility with legacy designs. Consider the 2.1V forward voltage drop for circuit design. Verify that the 3000-12000 mcd intensity range meets visibility requirements for the intended operating environment.

Part Context

This part belongs to the C503B series of 5mm round LEDs manufactured by Cree LED. The series includes variants with different viewing angles (15, 23, and 30 degrees) and colors. The RBS designation specifically indicates a red LED with a 23-degree viewing angle within the radial 5mm package family.

Replacement Considerations

Direct substitutes include other C503B-RBS variants with matching 23-degree angles and 5mm packages. Verify electrical parameters such as forward voltage and luminous intensity before substituting. Ensure the replacement maintains the same through-hole mounting style and lens transparency.
