Procurement Notes

Verify the exact binning codes for chromaticity and forward voltage during procurement. Ensure that the ordering suffix matches the required lumen class and color temperature specifications. Confirm compatibility with the intended driver circuitry regarding current requirements. Request the latest datasheet revision to ensure accurate thermal resistance values are considered for heat sink design.

Selection Notes

Select this component when high brightness and thermal stability are critical within a small footprint. Evaluate the thermal resistance of the application board against the datasheet limits to prevent junction temperature exceedance. Consider the optical angle requirements to determine if the integrated lens meets the illumination pattern needs without additional external optics.

Part Context

This part belongs to the XLamp C566 family, which represents a generation of high-performance LEDs focused on improving efficacy and thermal performance. The series is widely recognized in professional lighting markets for its robust construction and consistent photometric properties over time.

Replacement Considerations

Direct replacements must match the pinout, thermal pad dimensions, and optical center height. Verify that substitute parts offer comparable luminous flux at the same drive current. Check for identical chromaticity binning to maintain visual consistency in multi-LED arrays.
