LED Indication - Discrete Procurement Notes

Verify the specific bin code suffix (B56702C4) against the manufacturer's latest datasheet to ensure correct chromaticity coordinates and luminous intensity grading. Confirm that the 2-PLCC package dimensions align with the target PCB footprint. Check for RoHS compliance status as per the most recent product change notification or environmental declaration provided by Everlight.

LED Indication - Discrete Selection Notes

Select this component when a standard cool white SMD LED is required for general indication purposes. Ensure the design accommodates the 3.25V forward voltage drop at 20mA. Verify that the 120-degree viewing angle meets the optical requirements of the application. Consider the operating temperature range limits during thermal analysis of the final assembly.

LED Indication - Discrete Part Context

This part belongs to the 45-21 series of surface-mount LEDs from Everlight. The series typically offers various color options and intensities within a standardized 2-PLCC form factor. This specific model represents the cool white variant, distinguished by its specific phosphor composition and binning codes for consistent color performance across production batches.

LED Indication - Discrete Replacement Considerations

Direct substitutes may include other 2-PLCC cool white LEDs from manufacturers such as Kingbright or Lite-On, provided they match the 2.7mm x 2.0mm outline and 1.3mm height. Verify equivalent forward voltage and luminous intensity bins before substitution.
