C503B-ACS-CW0X0342

Overview

The C503B-ACS-CW0X0342 is a 5 mm (T-1 3/4) amber light-emitting diode from the Cree LED series. It features a clear, round lens with a domed top and operates at a typical forward voltage of 2.1 V. The component emits light at a peak wavelength of 591 nm with a luminous intensity of 4430 mcd. It has a viewing angle of 30 degrees and utilizes radial through-hole mounting. The device is RoHS compliant and designed for high reliability in outdoor environments.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture.
• Encapsulation resin contains UV inhibitors to minimize degradation from long-term direct sunlight exposure.
• Ensures stable light output over the operational life of the LED in harsh conditions.

Applications

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

Procurement Notes

Verify the specific part number against official Cree LED documentation to confirm electrical parameters and physical dimensions. Ensure compliance with RoHS standards if required by the target application. Cross-reference datasheets for thermal management requirements and maximum ratings before integration into circuit designs.

Selection Notes

Select this component for applications requiring high visibility amber indicators with a 30-degree viewing angle. Consider the 2.1 V forward voltage drop when designing drive circuits. The 5 mm through-hole package is suitable for standard PCB layouts. Evaluate environmental exposure needs to leverage the UV-resistant and moisture-resistant properties of the epoxy lens.

Part Context

This component belongs to the C503B family of 5 mm red and amber round LEDs manufactured by Cree LED. The family includes variants with different viewing angles (15, 23, and 30 degrees) and luminous intensities. The ACS suffix typically denotes the 30-degree viewing angle variant within this product line.

Replacement Considerations

Direct substitutes include other C503B-ACS variants from Cree LED with matching 30-degree viewing angles. Verify that alternative components meet the same 591 nm wavelength and 2.1 V forward voltage specifications to ensure optical and electrical compatibility.
