C503B-AAN-CA0C0342

Overview

The C503B-AAN-CA0C0342 is a single-color amber LED from the Cree C503B family, designed for through-hole mounting in a 5mm T-1 3/4 radial package. It features a round lens with a domed top and clear encapsulation. The component operates at a typical forward voltage of 2.1V with a test current of 20mA. It emits light at a dominant wavelength of 591nm, providing a luminous intensity range of 5860 to 23500 mcd. The viewing angle is specified at 15 degrees, ensuring focused light output suitable for high-readability applications.

Feature Summary

• Constructed with advanced optical-grade epoxy for superior high-temperature and high-moisture resistance.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure.
• Provides stable light output over the operational life of the LED in outdoor environments.

Applications

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

Procurement Notes

Verify the specific suffix CA0C0342 against official Cree documentation to confirm binning parameters and availability status. Cross-reference datasheet revisions to ensure compatibility with existing designs. Confirm RoHS compliance details as required by project specifications. Check for obsolescence notices or last-time buy recommendations prior to procurement planning.

Selection Notes

Select this component when high-intensity amber illumination is required for outdoor signage. The 15-degree viewing angle provides directional light control. Ensure the design accommodates the 5mm through-hole footprint and thermal requirements. Consider the UV-resistant epoxy properties for long-term durability in exposed environments compared to standard LEDs.

Part Context

This part belongs to the C503B series of 5mm round LEDs manufactured by Cree LED. The series includes red and amber variants with different beam angles (15, 23, and 30 degrees). The AAN designation typically indicates a 15-degree viewing angle amber LED within this family, optimized for readability in bright conditions.

Replacement Considerations

Direct substitutes include other C503B-AAN variants with different suffixes if binning differences are acceptable. Verify pin compatibility and luminous intensity ranges before substitution. No alternative part numbers are explicitly confirmed in the provided source material.
