QLSP28RD

Overview

The QLSP28RD is a discrete red LED indicator manufactured by Quelighting Corp, designed for surface-mount applications. It features a 4-PLCC package with a round lens having a domed top and a diameter of 2.40mm. The device emits light at a wavelength of 625nm with a viewing angle of 30 degrees. Typical forward voltage is specified at 1.9V under a test current of 50mA.

Feature Summary

• Surface-mount LED indicator in a compact 4-PLCC package
• Red emission with a 30-degree viewing angle
• Round lens design with a domed top profile

Applications

• General electronic equipment status indication
• Panel-mounted visual signaling
• Consumer appliance control interfaces

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and thermal characteristics before integration. Ensure compatibility with standard SMT reflow profiles for the 4-PLCC form factor. Cross-reference pin assignments and lens dimensions against the target PCB footprint to prevent mechanical interference during assembly.

Selection Notes

Select this component when a low-profile red indicator is required for surface-mount manufacturing processes. The 4-PLCC package offers reliable soldering stability compared to through-hole alternatives. Consider the 30-degree viewing angle for applications requiring focused visibility rather than wide-angle dispersion.

Part Context

QLSP28RD belongs to the discrete LED indicator category within Quelighting Corp's optoelectronics portfolio. It serves as a visual status signal source for various electronic systems. The product line emphasizes compact packaging solutions suitable for modern printed circuit board designs.

Replacement Considerations

Consult official distributor databases for direct cross-references. Verify that any substitute maintains identical 4-PLCC dimensions, forward voltage characteristics, and spectral output to ensure functional equivalence.
