LED Indication - Discrete Procurement Notes

Verify the specific suffix 'AC' against official Everlight documentation to confirm exact binning parameters, as generic listings may not reflect precise chromaticity or intensity grades. Confirm availability status directly with authorized distributors, as this component may be subject to production lifecycle changes or discontinuation notices. Ensure that the selected variant matches the required thermal and electrical specifications for the target application design.

LED Indication - Discrete Selection Notes

Select this component when a compact, low-profile cool white indicator is required for surface-mounted designs. The 2.70mm x 2.00mm footprint offers space efficiency compared to larger through-hole alternatives. Consider the 120-degree viewing angle and 2200 mcd intensity for visibility requirements. Verify compatibility with standard reflow soldering profiles and ensure the 3.25V forward voltage aligns with the system's power supply constraints.

LED Indication - Discrete Part Context

This part belongs to the 45-21 series of single-color LEDs from Everlight, which are characterized by their small PLCC form factor. The series provides various color and intensity options for different industrial and consumer applications. The 45-21/QK2C variant specifically targets cool white illumination needs within the standard SMD LED category, offering a balance between size, brightness, and cost-effectiveness for mass-produced electronics.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other 2-PLCC cool white LEDs from Everlight such as the 45-21/LK2C-B50634C6CB2/2T or 45-21/QK2C-B50632C4CB2/2T, provided they match the mechanical dimensions and electrical characteristics. Cross-referencing datasheets is essential to verify identical pin configurations and luminous intensity bins before implementation.
