QBLP674-IB

LED Indication - Discrete Overview

The QBLP674-IB is a blue InGaN surface-mount LED from the QT Brightek QBLP674 series. It features a PLCC-2 package with dimensions of 2.8mm x 1.4mm x 0.75mm and emits light at a primary wavelength of 470nm. The component operates with a typical forward voltage of 3.1V and a test current of 20mA. It offers a viewing angle of 120 degrees and is available in tape and reel packaging for automated assembly.

LED Indication - Discrete Feature Summary

• Utilizes InGaN technology for high-brightness blue emission
• Designed for surface-mount applications with a compact PLCC-2 footprint
• Features a wide 120-degree viewing angle for broad visibility

LED Indication - Discrete Applications

• General indicator lighting on electronic circuit boards
• Status indication in consumer electronics devices
• Panel status indicators for industrial control equipment

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version to confirm luminous intensity ranges, as sources vary between 125mcd and higher values. Ensure the PLCC-2 package dimensions match the target PCB land pattern. Confirm RoHS compliance status for the specific manufacturing batch before integration into regulated products.

LED Indication - Discrete Selection Notes

Select this component when a standard blue indicator is required in a low-profile SMD form factor. The 3.1V forward voltage aligns with common 3.3V logic systems. Consider the 120-degree viewing angle if wide-area visibility is necessary compared to narrower beam LEDs.

LED Indication - Discrete Part Context

This part belongs to the QBLP674 series of discrete LED indicators. It shares the same PLCC-2 package style as other variants in the line but differs in color and wavelength specifications. The series supports various colors including yellow-green and blue options for unified mechanical design across product lines.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other PLCC-2 blue LEDs such as the QBLP674-AG (note: AG is typically yellow/green, verify color code) or generic PLCC-2 blue LEDs from manufacturers like Kingbright or Everlight, ensuring identical pinout and thermal characteristics.
