C503B-AAS-CA0B0341

Overview

The C503B-AAS-CA0B0341 is a single-color amber LED from the Cree C503B family, designed for through-hole mounting in a 5 mm (T-1 3/4) package. It features an oval lens with a 15-degree viewing angle and emits at a dominant wavelength of 591 nm. The component operates with a maximum forward current of 20 mA and a forward voltage of 2.1 V, dissipating up to 130 mW. Luminous intensity ranges from 5860 to 23500 mcd. It complies with RoHS standards.

Feature Summary

• Utilizes advanced optical-grade epoxy encapsulation resin containing UV inhibitors to minimize degradation from long-term direct sunlight exposure.
• Provides superior light output and excellent readability specifically engineered for outdoor electronic signs and signals.
• Ensures stable light output over the operational life of the LED while maintaining high resistance to temperature and moisture.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the official datasheet to confirm exact luminous intensity binning and wavelength tolerances. Ensure that the selected variant matches the required forward current specifications for the target circuit design. Confirm availability status as manufacturing cycles may vary by region.

Selection Notes

Select this component when high-intensity amber illumination is required for outdoor visibility. The 15-degree beam angle provides focused light suitable for directional signaling applications. Consider the thermal management requirements associated with the 130 mW power dissipation rating during PCB layout.

Part Context

This part belongs to the C503B round LED family, which includes red and amber variants with different beam angles. The AAS designation indicates a 15-degree viewing angle configuration within the series. These LEDs are optimized for harsh environments requiring durability and consistent performance.

Replacement Considerations

Consult the official C503B datasheet for cross-reference options within the same product family. Verify compatibility regarding pin spacing, forward voltage characteristics, and mechanical footprint dimensions before substituting with alternative models.
