C503B-RAS-CY0B0AA2

Overview

The C503B-RAS-CY0B0AA2 is a single-color red light-emitting diode from the Cree LED C503B series. It utilizes a 5 mm (T-1 3/4) through-hole package with a round, domed lens configuration. The component emits at a dominant wavelength of 624 nm and operates with a typical forward voltage of 2.1 V. It features a narrow 15-degree viewing angle and delivers a luminous intensity range of 5860 to 23500 mcd. The device is constructed with optical-grade epoxy containing UV inhibitors for environmental stability.

Feature Summary

• High-intensity red emission optimized for superior readability in outdoor applications
• Advanced optical-grade epoxy encapsulation provides high resistance to temperature and moisture
• UV inhibitor integration minimizes degradation effects from long-term direct sunlight exposure
• Narrow 15-degree beam angle ensures focused light output for signaling purposes

Applications

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

Procurement Notes

Verify the specific suffix CY0B0AA2 against official Cree documentation to confirm exact binning parameters. Ensure compatibility with existing PCB layouts for the 5 mm T-1 3/4 radial lead format. Confirm RoHS compliance status for the specific manufacturing batch prior to final integration into the design.

Selection Notes

Select this component when a narrow 15-degree beam profile is required for directional visibility. The 5 mm form factor suits standard through-hole mounting processes. Consider the 2.1 V forward voltage drop for circuit power budgeting. Verify that the 624 nm wavelength meets the specific color requirements for the target signage application.

Part Context

This part belongs to the C503B family of 5 mm round LEDs designed for harsh environments. The RAS designation indicates a red variant with a 15-degree viewing angle. These components are engineered for durability in outdoor sign and signal applications where consistent light output over the product lifecycle is critical.

Replacement Considerations

Direct substitutes within the same series include C503B-RAN-CY0B0AA2 or C503B-RCS-CY0B0AA2, provided the viewing angle difference is acceptable. Cross-model replacements require verification of mechanical dimensions and electrical characteristics.
