C503B-AAS-CZ0A0341

Overview

The C503B-AAS-CZ0A0341 is a single-color amber LED from the Cree LED C503B series, housed in a 5 mm (T-1 3/4) through-hole package. It features a round lens with a 15-degree viewing angle and emits at a dominant wavelength of 591 nm. The component has a maximum forward current of 20 mA, a typical forward voltage of 2.1 V, and a luminous intensity range of 5860 to 23500 mcd. It utilizes advanced optical-grade epoxy for high temperature and moisture resistance.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture.
• Encapsulation resin contains UV inhibitors to minimize degradation from direct sunlight exposure.
• Designed for excellent readability in outdoor signage and signal applications.

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm lens color, intensity binning, and packaging type. Check the manufacturer's official documentation for current lifecycle status, as some variants may be recommended against new design or discontinued. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement.

Selection Notes

Select this component when high-brightness amber illumination is required for long-distance visibility in outdoor environments. The 15-degree beam angle offers focused light output suitable for directional signaling. Consider the UV-resistant epoxy properties for projects exposed to prolonged sunlight to ensure stable light output over the product's operational lifetime.

Part Context

This part belongs to the C503B family of 5 mm round LEDs, which includes red and amber variants with different viewing angles (15, 23, and 30 degrees). The AAS suffix specifically denotes the 15-degree viewing angle variant within the amber color group. These LEDs are engineered for robust performance in harsh outdoor conditions compared to standard indicator LEDs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other 5 mm T-1 3/4 amber LEDs by checking electrical parameters and mechanical dimensions.
