150040WS73240

Overview

The Würth Elektronik 150040WS73240 is a single-color surface-mount LED from the WL-SMCC series, designed for compact electronic assemblies. It emits white light with a peak wavelength of approximately 625nm to 630nm range depending on specific binning, though typically categorized as white in this package. The component features a standard 0402 (1005 metric) footprint measuring 1.00mm x 0.50mm x 0.50mm maximum height. It operates with a typical forward voltage of 2.8V at a test current of 20mA, delivering a luminous intensity of 300mcd. The device offers a wide viewing angle of 120 degrees and utilizes a colorless, water-clear lens.

Feature Summary

• Compact 0402 surface-mount form factor suitable for space-constrained PCB layouts
• High luminous intensity output of 300mcd for clear visibility
• Wide 120-degree viewing angle for broad illumination coverage
• RoHS compliant construction with moisture sensitivity level 3

Applications

• Status indication in portable consumer electronics
• Backlighting for small displays or keypads
• Indicator lights in automotive interior modules
• Signal indication in industrial control panels

Procurement Notes

Verify the specific datasheet version for the exact peak wavelength and forward voltage tolerance, as these parameters can vary slightly between manufacturing batches. Confirm that the 0402 package dimensions align with your stencil design and reflow profile requirements. Ensure compatibility with RoHS3 regulations if operating in restricted substance zones. Check moisture sensitivity level handling procedures during storage and assembly.

Selection Notes

Select this component when a high-brightness white indicator is required in a minimal footprint. The 2.8V forward voltage is higher than red or amber variants, requiring appropriate driver circuit consideration. The 300mcd intensity provides strong visibility compared to lower-output alternatives. Consider the 120-degree beam width for applications requiring diffuse rather than focused light emission.

Part Context

This part belongs to Würth Elektronik's WL-SMCC series of compact chip LEDs. The series includes various colors such as red, amber, green, and blue in the same 0402 package style. The 150040 prefix indicates the specific product line within their discrete LED portfolio, standardized for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes include other manufacturers' 0402 white LEDs with similar forward voltage and intensity ratings. Cross-reference part numbers like those from Samsung Electro-Mechanics or Everlight may offer comparable performance. Verify mechanical dimensions and spectral characteristics before substitution.
