C503B-RBS-CY0Z0AA1

Overview

The C503B-RBS-CY0Z0AA1 is a red round LED from the Cree LED series, housed in a 5 mm (T-1 3/4) through-hole package. It features a clear lens and emits at a dominant wavelength of 624 nm. The component operates with a forward voltage of 4 V and a maximum forward current of 30 mA. It delivers a luminous intensity range of 3000 to 12000 mcd with a viewing angle of 23 degrees. The device has a power rating of 120 mW and complies with RoHS standards.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior high-temperature and high-moisture resistance for outdoor durability.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Ensures stable light output over the operational life of the LED in demanding environmental conditions.

Applications

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

Procurement Notes

Verify the specific suffix CY0Z0AA1 against official Cree documentation to confirm exact binning parameters, as ordering suffixes define precise electrical and optical characteristics. Ensure compatibility with existing PCB footprints for the 5 mm T-1 3/4 package. Confirm RoHS compliance status for the specific manufacturing batch. Check for any recent Product Change Notifications regarding packaging or material updates before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high readability in outdoor environments due to its UV-resistant encapsulation. The 23-degree viewing angle offers a balance between focused intensity and broader visibility compared to narrower beams. Ensure circuit design accommodates the 4 V forward voltage and 30 mA maximum current limits. Consider the 120 mW power dissipation rating when designing thermal management strategies for enclosed assemblies.

Part Context

This part belongs to the Cree C503B family of 5-mm round LEDs, designed for robust performance in signage and signal applications. The RBS designation indicates a red color variant with a 23-degree viewing angle. These LEDs utilize advanced epoxy technology to maintain stability under harsh weather conditions, making them suitable for critical public information displays where consistent brightness is essential.
