C503B-ACN-CY0Z0252

Overview

The C503B-ACN-CY0Z0252 is a through-hole amber LED from the Cree C503B series, housed in a 5 mm (T-1 3/4) round package with a clear lens. It operates at a typical forward voltage of 2.1 V and features a dominant wavelength of 591 nm. The component delivers a luminous intensity of 8930 mcd at a test current of 20 mA, with a viewing angle of 30 degrees. Electrical ratings include a maximum forward current of 50 mA and a maximum power dissipation of 130 mW. The device complies with RoHS3 standards and is classified under MSL level 1.

Feature Summary

• Utilizes advanced optical-grade epoxy encapsulation for superior high-temperature and high-moisture resistance suitable for outdoor environments.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Provides stable light output over the operational life of the LED in demanding signal applications.

Applications

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

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official datasheets. Confirm that the received units match the specified 591 nm wavelength and 8930 mcd intensity. Ensure compliance with RoHS3 regulations as documented. Check for any specific handling requirements related to the through-hole mounting process.

Selection Notes

Select this component for applications requiring high visibility in outdoor signage due to its UV-resistant construction. Consider the 30-degree viewing angle and 5 mm form factor for standard panel mounting. Verify that the 2.1 V forward voltage aligns with the circuit design constraints. Note that this specific variant is designated as Not Recommended for New Designs (NRND).

Part Context

This part belongs to the Cree C503B family of 5 mm round LEDs, which includes red and amber variants with different beam angles. The 'ACN' suffix indicates an amber color with a 30-degree viewing angle and oval lens shape. This series is engineered for readability in harsh outdoor conditions, distinguishing it from general-purpose indicator LEDs.
