Procurement Notes

Verify RoHS3 compliance and moisture sensitivity level 3 requirements during storage and handling. Confirm PLCC-2 package compatibility with PCB footprint designs. Ensure thermal management aligns with the specified operating temperature range of -40°C to +85°C. Check datasheet for specific binning parameters regarding color temperature and luminous intensity before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring a compact surface-mount white LED with a 5700K color temperature. The PLCC-2 package suits space-constrained designs needing 120-degree visibility. Consider the 2.8V forward voltage drop for circuit design. Verify that the 20mA drive current matches existing system capabilities. Evaluate the silicone encapsulation benefits against environmental exposure requirements.

Part Context

This part belongs to the ASMT-UWB1 series of high-power LEDs manufactured by Broadcom Limited. The series features various color temperatures and intensities within the same PLCC-2 form factor. These components are designed for general illumination and indication purposes, offering a balance of optical performance and mechanical robustness for consumer and industrial electronics.

Replacement Considerations

Cross-reference with other ASMT-UWB1 variants such as ASMT-UWB1-NX3A2 or ASMT-UWB1-NX7A2 if different color temperatures are acceptable. Verify pinout and dimensional compatibility when substituting with generic PLCC-2 white LEDs. Ensure equivalent forward voltage and current ratings to maintain circuit integrity.
