C503B-AAS-CA0C0251-015

Overview

The C503B-AAS-CA0C0251-015 is a single-color amber LED from the Cree LED C503B series, designed for through-hole mounting in a T-1 3/4 (5 mm) package. It features a round lens with a domed top and a clear colorless finish. The component operates at a forward current of 20 mA with a forward voltage of 2.1 V and a maximum power rating of 130 mW. It emits light at a dominant wavelength of 591 nm with a luminous intensity of 5860 mcd. The device offers a narrow viewing angle of 15 degrees and functions within a temperature range of -40°C to +100°C.

Feature Summary

• Utilizes advanced optical-grade epoxy encapsulation for superior high-temperature and high-moisture resistance.
• Contains UV inhibitors in the resin to minimize degradation from direct sunlight exposure.
• Provides stable light output over the operational life of the LED.
• Features a narrow beam angle optimized for long-distance readability.

Applications

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

Procurement Notes

Verify the specific suffix CA0C0251-015 against the official datasheet to confirm binning and packaging details. Check the lifecycle status as some variants in this family are marked NRND. Ensure compatibility with existing PCB footprints for the T-1 3/4 package before procurement.

Selection Notes

Select this component when a narrow 15-degree viewing angle is required for signage applications. Compare the 5860 mcd intensity against other series like ABS or ACN if wider dispersion is needed. Confirm that the 2.1 V forward voltage aligns with the circuit design constraints.

Part Context

This part belongs to the C503B family of 5-mm Red and Amber Round LEDs manufactured by Cree LED. The family includes variants with different beam angles (15, 23, and 30 degrees) and intensities. These LEDs are engineered for outdoor durability and high visibility in signaling environments.

Replacement Considerations

Check for direct substitutes within the C503B series such as C503B-AAN or C503B-ABS if beam angle or intensity requirements differ. Verify pinout and mechanical dimensions for drop-in compatibility with existing assemblies.
