QLSP05RD

Overview

The QLSP05RD is a red discrete LED from Quelighting Corp, emitting at 618nm (range 612–624nm). It features a round lens with a flat top and clear transparency. The component operates with a typical forward voltage of 2.2V and delivers a millicandela rating of 2750mcd. It utilizes a 1411 (3528 metric) surface mount package with a 2.40mm diameter lens size.

Feature Summary

• Red color emission optimized for specific wavelength requirements
• Clear lens design with a round shape and flat top profile
• Surface mount construction for PCB integration

Applications

• Discrete LED indication circuits
• PCB assembly lighting components
• Visible LED indicator applications

Procurement Notes

Verify the exact part number against manufacturer documentation to ensure compatibility with 1411 footprint requirements. Confirm that the 618nm wavelength aligns with optical system specifications. Check datasheet limits for forward current and thermal management needs during implementation.

Selection Notes

Select this component when a compact red indicator is required with high luminous intensity. The 2750mcd rating supports visibility in standard environments. Ensure the 2.2V forward voltage matches the driving circuit capabilities. The 1411 package size offers space efficiency for dense board layouts.

Part Context

QLSP05RD belongs to the visible LED category within Quelighting Corp's portfolio. It is distinct from horticulture or UV series products. The component serves as a general-purpose indicator rather than a specialized lighting source. Its active lifecycle status confirms ongoing availability for new designs.

Replacement Considerations

Cross-reference with other 1411 red LEDs if supply constraints exist. Verify spectral match and mechanical dimensions before substitution. No direct substitute part numbers are confirmed in public documentation.
