C503B-AAN-CA0C0341

Overview

The C503B-AAN-CA0C0341 is a single-color amber LED from the Cree LED C503B family, designed for through-hole mounting in a T-1 3/4 (5 mm) round package with a domed lens. It emits at a dominant wavelength of 591 nm with a luminous intensity of 12,000 mcd and a viewing angle of 15 degrees. The component operates with a forward current of 20 mA and a forward voltage of 2.1 V, rated at 130 mW power. It functions within a temperature range of -40°C to +100°C.

Feature Summary

• Constructed with advanced optical-grade epoxy containing UV inhibitors for superior high-temperature and moisture resistance.
• Provides stable light output over the component's life despite long-term exposure to direct sunlight.
• Features a clear, colorless dome-shaped lens optimized for high readability in outdoor environments.

Applications

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

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before finalizing any new product development plans. Confirm that the specific ordering suffix matches the required optical and electrical parameters. Ensure compliance with RoHS requirements and check for any regional sales restrictions or discontinuation notices prior to procurement.

Selection Notes

Select this component for applications requiring high-intensity amber indication with a narrow 15-degree beam profile. Consider the through-hole form factor and robust environmental sealing when designing for outdoor signage. Evaluate thermal management needs given the operating temperature limits and power rating.

Part Context

This part belongs to the C503B series of 5-mm round LEDs manufactured by Cree LED. The series includes red and amber variants with different viewing angles (15, 23, and 30 degrees). The C503B-AAN variant specifically offers a 15-degree viewing angle and higher luminous intensity compared to other series members.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on matching package dimensions, electrical characteristics, and optical performance specifications.
