C503B-AAN-CZ0B0341

Overview

The C503B-AAN-CZ0B0341 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) round package. It features a domed lens with a clear colorless appearance and emits at a dominant wavelength of 591 nm. The component provides a luminous intensity of 12,000 mcd with a viewing angle of 15 degrees. Electrical characteristics include a forward voltage of 2.1 V and a forward current of 20 mA, supporting a power rating of 130 mW. It operates within a temperature range of -40°C to +100°C.

Feature Summary

• High-intensity amber light output optimized for superior readability in outdoor environments
• Advanced optical-grade epoxy encapsulation providing high resistance to heat and moisture
• UV inhibitor integration in the resin to minimize degradation from direct sunlight exposure
• Stable light output maintained over the operational life of the LED

Applications

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

Procurement Notes

Verify the obsolete status of this component before procurement, as it is marked as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors or secondary markets. Ensure that any replacement strategy accounts for potential supply chain discontinuation risks associated with legacy part numbers.

Selection Notes

Select this component when a narrow 15-degree beam angle is required for focused signaling applications. The amber emission at 591 nm ensures high visibility in daylight conditions. Consider the through-hole form factor for robust mechanical attachment in signage structures where surface-mount alternatives are unsuitable.

Part Context

This part belongs to the C503B family 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 high luminous intensity suitable for demanding outdoor sign and signal applications requiring long-term stability.
