C503B-ACN-CX0Y0251

Overview

The C503B-ACN-CX0Y0251 is a single-color amber LED from the Cree C503B series, designed for through-hole mounting in a T-1 3/4 (5 mm) package. It emits at a dominant wavelength of 591 nm with a typical forward voltage of 2.1 V and a test current of 20 mA. The component features a clear dome lens and offers a luminous intensity of 6000 mcd with a 30-degree viewing angle. Rated for operation between -40°C and +100°C, it dissipates up to 130 mW. This part is marked as Not Recommended for New Designs (NRND).

Feature Summary

• Utilizes advanced optical-grade epoxy encapsulation for superior high-temperature and moisture resistance.
• Contains UV inhibitors within the resin to minimize sunlight exposure effects and ensure stable light output.
• Features a round, domed lens design optimized for excellent readability in outdoor environments.

Applications

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

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before integration into new products. Confirm RoHS compliance details via official documentation. Check for potential obsolescence or end-of-life notices from Cree LED prior to finalizing procurement plans.

Selection Notes

Select this component for applications requiring a 5 mm through-hole amber LED with a 30-degree beam angle. Ensure the circuit supports a 2.1 V forward voltage drop at 20 mA. Consider the NRND status when planning long-term production cycles.
