C503B-RBS-CX0Y0AA2

Overview

The C503B-RBS-CX0Y0AA2 is a single-color red LED from the Cree C503B family, designed for through-hole mounting. It features a 5mm round dome lens with a clear colorless appearance. The component emits light at a dominant wavelength of 624nm. Typical luminous intensity ranges from 3000 to 12000 mcd. The forward voltage is typically 2.1V at a test current of 20mA. It has a viewing angle of 23 degrees and a maximum height of 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 effects of long-term direct sunlight exposure.
• Provides stable light output over the life of the LED in outdoor environments.

Applications

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

Procurement Notes

Verify the specific suffix against official Cree datasheets to confirm exact luminous intensity binning and wavelength tolerances. Ensure the procurement channel provides valid RoHS compliance documentation. Confirm that the package type matches the required through-hole assembly process for the target application.

Selection Notes

Select this component when a 23-degree viewing angle is required for red indicator applications. Consider the 5mm radial package dimensions for PCB layout constraints. Evaluate the thermal management requirements based on the 130mW power rating if operating near maximum limits.

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 suffix specifically denotes the Red color with a 23-degree beam spread configuration within this product line.

Replacement Considerations

Direct substitutes include other C503B-RBS variants with matching electrical characteristics. Cross-reference with similar 5mm T-1 3/4 through-hole red LEDs from other manufacturers only if pinout and mechanical dimensions are identical.
