C503B-ACS-CX0Y0342

Overview

The C503B-ACS-CX0Y0342 is a single-color amber LED from the Cree LED C503B series, housed in a 5 mm (T-1 3/4) through-hole package. It features a clear lens with a 30-degree viewing angle and emits light at a dominant wavelength of 591 nm. The component operates with a typical forward voltage of 2.1 V at a test current of 20 mA, delivering a luminous intensity range of 3000 to 8200 mcd. It has a maximum power dissipation of 130 mW and is compliant with RoHS standards.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct lens shape and intensity binning. Confirm availability status as some variants may be marked as Not Recommended for New Designs. Cross-reference electrical parameters such as forward voltage and luminous intensity with the manufacturer's latest documentation before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high visibility in bright ambient conditions due to its specific intensity and wavelength characteristics. Ensure the circuit design accommodates the 2.1 V forward voltage drop and 20 mA operating current. Consider the 30-degree viewing angle for optimal beam distribution in signage applications.

Part Context

This part belongs to the C503B family of 5-mm round LEDs designed for outdoor readability. The series offers various intensity levels and viewing angles to suit different signaling requirements. The ACS designation typically indicates a specific intensity bin within the amber color category, optimized for standard signage visibility.

Replacement Considerations

Direct substitutes include other C503B-ACS variants with matching 30-degree viewing angles and similar luminous intensity ranges. Verify that any replacement maintains the same 5 mm T-1 3/4 package dimensions and through-hole mounting style to ensure mechanical compatibility.
