• Surface mount construction for automated PC board assembly

Applications

• Status indication in consumer electronics
• Power state signaling in compact devices
• Panel indicators for space-sensitive applications

Procurement Notes

Verify the specific ordering suffix to confirm exact binning and packaging specifications. Ensure compatibility with standard SMT reflow profiles during integration. Cross-reference official datasheets for precise thermal and electrical limits before finalizing design implementations.

Selection Notes

Select this component for applications requiring blue visual feedback in restricted spaces. The 120-degree viewing angle offers broad visibility compared to narrower beam alternatives. Confirm that the 2.7V forward voltage aligns with the target circuit's drive capabilities and power constraints.

Part Context

This part belongs to Quelighting Corp's miniature SMD LED series designed for high-density PCB layouts. The family emphasizes automated assembly compatibility and spatial efficiency. The QLSP23BA specifically addresses the need for distinct blue status indicators in modern electronic hardware.

Replacement Considerations

Direct substitutes require matching the 0402 footprint, 465nm wavelength, and 2.7V forward voltage. Verify pinout compatibility and lumen output if brightness consistency is critical. Consult manufacturer cross-reference lists for verified equivalent components.
