Procurement Notes
Verify the specific binning codes and chromaticity coordinates required for your application against the manufacturer's datasheet specifications. Confirm that the ordering suffix matches the desired color temperature and luminous intensity ranges. Ensure compliance with RoHS directives and JEDEC moisture sensitivity level requirements during procurement planning.
Selection Notes
Select this component when high brightness and thermal stability are critical for indicator or backlighting tasks. Consider the 0.15 A drive capability and robust packaging for designs requiring long-term reliability in automotive or industrial settings. Evaluate the physical footprint compatibility with existing PCB layouts before integration.
Part Context
This part belongs to Broadcom's PLCC-4 SMT LED family, specifically the Super 0.5W Cool White Power series. These components are engineered to outperform traditional mid-power LEDs by delivering increased light output while maintaining a compact form factor. The series is widely used in applications requiring durable, high-efficiency illumination sources.
Replacement Considerations
Direct substitutes include other variants within the ASMT-QWBC-Nxxxx series, such as ASMT-QWBC-NAKZE or ASMT-QWBC-NDLEE, provided they meet the same electrical and mechanical specifications. Verify pinout compatibility and thermal characteristics when cross-referencing alternative part numbers.
