C503B-ACS-CY0Z0342

Overview

The C503B-ACS-CY0Z0342 is a high-power LED module from Cree's XLamp series, designed for demanding lighting applications. It features an amber-colored phosphor-coated lens and utilizes a ceramic substrate for enhanced thermal management. The device operates with a forward voltage typically ranging between 18V and 22V at rated current. It delivers high luminous flux output while maintaining color consistency across batches. The component is engineered for long-term reliability in commercial and industrial fixtures.

Feature Summary

• Utilizes advanced ceramic substrate technology for superior heat dissipation and thermal stability compared to traditional PCB-based modules.
• Features a specialized amber phosphor coating on the lens to achieve precise chromaticity targets required for specific signaling and accent lighting applications.
• Designed with robust epoxy encapsulation to protect internal die structures against environmental stressors and mechanical shock.

Applications

• Commercial architectural accent lighting requiring warm or amber tones
• Industrial safety and warning signage systems
• Specialized outdoor landscape illumination fixtures

Procurement Notes

Verify the specific binning codes for chromaticity and forward voltage prior to ordering, as these parameters vary significantly within the product line. Ensure that the driving circuitry matches the electrical characteristics of the selected bin. Confirm compatibility with existing thermal interface materials and mounting hardware used in the target fixture design to maintain performance specifications.

Selection Notes

Select this model when amber color rendering is critical for the application's aesthetic or functional requirements. Consider the thermal resistance of the host system, as the module's performance is heavily dependent on effective heat sinking. Evaluate the optical distribution needs, as the lens geometry influences beam spread. Compare total cost of ownership against lower-power alternatives if lumen output requirements are modest.

Part Context

This module belongs to the XLamp C503B family, which represents a generation of high-intensity discrete LED packages. These components are widely adopted in general illumination and specialty lighting markets due to their balance of efficiency and power density. The C503B series offers various color options, with this specific variant focusing on amber spectrum output for niche applications.

Replacement Considerations

Direct replacements must match the physical footprint, pin configuration, and thermal pad dimensions. Verify that substitute parts offer comparable luminous flux and chromaticity coordinates. Check if alternative manufacturers provide equivalent ceramic-based packages with similar thermal resistance values to ensure seamless integration without redesigning the cooling system.
