C503B-RCS-CXAYAAA1-030

Overview

The C503B-RCS-CXAYAAA1-030 is a 5-mm round, single-color red LED from the Cree LED C503B family. It features a T-1 3/4 (5 mm) through-hole package with a dome lens shape and clear colorless lens material. The device emits red light at a typical dominant wavelength of 624 nm. Key electrical parameters include a forward voltage of 2.1 V and a maximum power dissipation of 130 mW. The component offers a luminous intensity range of 3000 to 12000 mcd and provides a viewing angle of 30 degrees.

Feature Summary

• Advanced optical-grade epoxy encapsulation for superior high-temperature and high-moisture resistance in outdoor environments
• Encapsulation resin contains UV inhibitors to minimize long-term sunlight exposure effects and ensure stable light output
• Designed for excellent readability in demanding outdoor sign and signal applications

Applications

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

Procurement Notes

Verify RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Confirm current lifecycle status as some variants may be marked Not Recommended for New Designs (NRND). Ensure ordering suffixes match specific binning requirements for wavelength and intensity. Check for any regional distribution restrictions before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high visibility in bright outdoor conditions due to its superior light output. The 30-degree viewing angle balances beam spread and intensity. Ensure circuit design accommodates the 2.1 V forward voltage and 20 mA typical forward current. Consider the 5 mm package dimensions for PCB layout compatibility in signage assemblies.

Part Context

This part belongs to the C503B series of 5-mm round LEDs manufactured by Cree LED. The series includes red and amber variants with different viewing angles (15, 23, and 30 degrees). The 'RCS' designation indicates a red color with a 30-degree viewing angle. These LEDs are engineered for durability and performance in harsh outdoor environments, distinguishing them from standard indicator LEDs.

Replacement Considerations

Direct substitutes within the same family include other C503B variants with matching 30-degree viewing angles, such as C503B-ACS or C503B-RCN, depending on required color. Verify that alternative parts meet the same luminous intensity and forward voltage specifications to maintain system performance.
