C503B-ACS-CYAZA341-030

Overview

The C503B-ACS-CYAZA341-030 is a single-color amber LED from the Cree C503B series, housed in a 5 mm (T-1 3/4) radial through-hole package. It features a clear colorless lens with an elliptical shape measuring 8.6 x 5 mm and a viewing angle of 30 degrees. The component operates at a forward voltage of 2.6 V with a maximum forward current of 50 mA and a power dissipation rating of 130 mW. It emits light at a dominant wavelength of 593 nm with a luminous intensity of 12,000 mcd. The device is RoHS compliant and designed for high-temperature and moisture resistance.

Feature Summary

• Constructed with advanced optical-grade epoxy containing UV inhibitors to minimize degradation from long-term direct sunlight exposure.
• Provides superior light output and excellent readability specifically engineered for outdoor sign and signal applications.
• Features high-temperature and high-moisture resistance performance suitable for demanding environmental conditions.

Applications

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

Procurement Notes

Verify the specific suffix CYAZA341-030 against official datasheets to confirm exact wavelength and intensity binning, as Cree part numbers are highly sensitive to alphanumeric codes. Confirm availability status, as this specific variant may be marked as Not Recommended for New Design (NRND). Ensure procurement channels provide original manufacturer documentation to validate RoHS compliance and lead times before finalizing orders.

Selection Notes

Select this component when a 30-degree viewing angle and 593 nm amber emission are required for outdoor visibility. Compare against the C503B-ACN series if a different lens shape or intensity range is needed. Verify that the 50 mA maximum forward current aligns with the target circuit design. Consider the T-1 3/4 package dimensions for PCB layout constraints and mechanical mounting requirements.

Part Context

This part belongs to the Cree C503B family of 5-mm round LEDs, which includes red and amber variants. The series is characterized by its use of UV-inhibitor epoxy for durability in outdoor environments. Other members include C503B-RCS and C503B-ABS, differing primarily in color, intensity, and viewing angle specifications while sharing the same fundamental package and material construction.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific configuration are not available in the provided source data. Engineers should consult the official Cree LED replacement guide or contact the manufacturer directly for validated cross-reference information regarding discontinued or NRND components.
