LED Indication - Discrete Procurement Notes

Verify the specific binning codes for luminous intensity and chromaticity coordinates prior to procurement, as these vary within the product family. Confirm that the supply chain source provides original manufacturer documentation to ensure authenticity. Check for any recent Product Change Notifications regarding material or process updates that may affect compatibility with existing assembly lines.

LED Indication - Discrete Selection Notes

Select this component when a standard cool white SMD LED is required for general indication purposes. Ensure the application circuit can accommodate the 3.25V forward voltage drop at 20mA. Consider the 120-degree viewing angle suitability for the intended optical path. Verify that the thermal management strategy aligns with the device's operating temperature range.

LED Indication - Discrete Part Context

This part belongs to the 45-21 series of low-power white LEDs from Everlight. It shares the same physical footprint and electrical interface as variants like 45-21/QK2C-B50632C4CB2/2T but differs in specific optical binning. The series is designed for cost-effective integration into consumer electronics and industrial control boards requiring reliable white illumination.

LED Indication - Discrete Replacement Considerations

Direct replacements include 45-21/QK2C-B50632C4CB2/2T and 45-21/LK2C-B50634C6CB2/2T, provided the luminous intensity bins are matched. Cross-reference datasheets to confirm identical mechanical dimensions and soldering profiles before substitution.
