C503B-RAS-CY0Z0AA2

Overview

The C503B-RAS-CY0Z0AA2 is a red light-emitting diode from the Cree LED C503B series. It features a 5 mm (T-1 3/4) round package with a clear lens and radial through-hole mounting configuration. The device emits at a dominant wavelength of 624 nm with a narrow 15-degree viewing angle. Typical forward voltage is 2.1 V, and it supports a maximum forward current of 20 mA. Luminous intensity ranges from 5860 to 23500 mcd, with a maximum power dissipation of 130 mW.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for outdoor durability.
• Encapsulation resin includes UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Narrow 15-degree beam angle ensures focused light output for enhanced readability in signage applications.

Applications

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

Procurement Notes

Verify the specific suffix CY0Z0AA2 against the official C503B datasheet to confirm exact luminous intensity binning and wavelength tolerances. Ensure the procurement channel sources genuine components to maintain optical performance standards. Confirm RoHS compliance status matches current regulatory requirements before finalizing orders.

Selection Notes

Select this component when a narrow 15-degree viewing angle is required for precise directional lighting in outdoor environments. Consider the 5 mm T-1 3/4 form factor for compatibility with standard through-hole PCB layouts. Evaluate the 2.1 V forward voltage drop for circuit design efficiency relative to other colors in the C503B family.

Part Context

This part belongs to the C503B family of 5-mm Red and Amber Round LEDs designed for robust outdoor performance. The series utilizes specialized encapsulation materials to withstand harsh environmental conditions while maintaining stable light output over the product lifecycle.
