C503B-RCS-CXAYCAA2-030

Overview

The C503B-RCS-CXAYCAA2-030 is a red single-color LED from the Cree LED C503B family, housed in a 5 mm (T-1 3/4) through-hole package. It features a round lens with a 30-degree viewing angle and emits at a dominant wavelength of 624 nm. The component operates with a forward voltage of approximately 2.1 V and a maximum forward current of 20 mA, delivering a luminous intensity range of 3000 to 12000 mcd. It is constructed with optical-grade epoxy containing UV inhibitors for high temperature and moisture resistance, ensuring stable light output over its operational life.

Feature Summary

• Constructed with advanced optical-grade epoxy resin containing UV inhibitors to minimize degradation from direct sunlight exposure.
• Provides superior high-temperature and high-moisture resistance performance suitable for demanding outdoor environments.
• Features a 30-degree viewing angle designed for excellent readability in electronic signage applications.

Applications

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

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct luminous intensity binning and wavelength tolerance. Confirm RoHS compliance status and lead times with authorized distributors, as availability may vary by region. Check for end-of-life notifications or recommended replacement parts before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high visibility in bright outdoor conditions due to its robust encapsulation and wide viewing angle. Ensure circuit design accommodates the specified forward voltage and current limits. Consider environmental factors such as UV exposure and humidity when evaluating long-term reliability requirements for the installation site.

Part Context

This part belongs to the C503B series of round LEDs, which are optimized for outdoor sign and signal applications. The series offers various colors and viewing angles, utilizing durable materials to maintain performance under harsh weather conditions. It represents a standard through-hole solution for legacy and new designs requiring reliable indicator lighting.

Replacement Considerations

Consult official Cree LED documentation for verified substitute part numbers within the same family or series that match electrical and mechanical specifications. Do not assume cross-compatibility with other manufacturers' 5mm LEDs without verifying pinout, voltage, and intensity parameters.
