C503B-AAS-CZ0B0342

Overview

The C503B-AAS-CZ0B0342 is a single-color amber LED from the Cree C503B series, housed in a 5 mm (T-1 3/4) round package with a clear lens. It operates at a forward voltage of 2.6 V and has a maximum power dissipation of 130 mW. The device emits light at a dominant wavelength of 593 nm with a viewing angle of 15 degrees. Typical luminous intensity ranges from 5860 to 23500 mcd. It features through-hole mounting and complies with RoHS standards.

Feature Summary

• High-brightness amber emission optimized for outdoor readability
• Advanced optical-grade epoxy for high-temperature and moisture resistance
• UV inhibitors in encapsulation resin for stable long-term output
• 15-degree viewing angle for focused directional lighting

Applications

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

Procurement Notes

Verify component authenticity against official Cree LED documentation before integration. Confirm that the specific suffix matches required electrical tolerances and binning categories. Ensure storage conditions prevent moisture damage prior to soldering. Check for end-of-life status or recommended replacement parts if current supply is limited. Validate compliance with local environmental regulations regarding lead-free materials.

Selection Notes

Select this component for applications requiring high-intensity amber illumination with a narrow beam profile. The 15-degree viewing angle suits tasks needing concentrated visibility over distance. Consider the 5 mm through-hole form factor for legacy board designs. Evaluate thermal management requirements given the 130 mW power dissipation limit. Compare against wider-angle variants if broader dispersion is needed.

Part Context

This part belongs to the C503B family of 5 mm round LEDs designed for transport signage markets. The series offers superior light output and durability in harsh outdoor environments. The amber variant specifically targets signaling applications where color distinction is critical. The product line emphasizes stability under direct sunlight exposure due to UV-resistant materials.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative amber LEDs from other manufacturers. Ensure mechanical dimensions and pin configurations match the original footprint.
