QLSP1306R

Overview

The QLSP1306R is a discrete red LED indicator manufactured by Quelighting Corp, housed in a surface-mount 0603 (1608 Metric) package. It features a clear lens and operates with a forward voltage of 2.1V at a standard current of 20mA. The component emits light with a dominant wavelength of 623nm and a peak wavelength of 608nm. Designed for independent configuration, it provides reliable visual indication suitable for compact electronic assemblies requiring precise spatial constraints.

Feature Summary

• Surface-mount 0603 package design for automated assembly
• Clear lens configuration for optimized light transmission
• Independent single-element LED structure
• Red emission spectrum centered at 623nm

Applications

• Status indication on consumer electronics PCBs
• Power state signaling in industrial control panels
• Visual alerts in automotive interior modules
• Indicator lights in medical device interfaces

Procurement Notes

Verify manufacturer part number accuracy against official Quelighting Corp documentation before ordering. Confirm that the 0603 package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the 20mA operating current to maintain longevity. Cross-reference datasheet specifications for forward voltage tolerance to guarantee compatibility with driving circuits.

Selection Notes

Select this component when a low-profile red indicator is required for space-constrained designs. The 0603 form factor supports high-density mounting compared to larger through-hole alternatives. Consider the 2.1V forward voltage drop when designing series resistor networks or constant current drivers. Verify that the 623nm wavelength meets visibility requirements for the specific application environment.

Part Context

QLSP1306R belongs to Quelighting Corp's discrete LED indicator series, which includes various colors and package sizes such as the QLSP1306A. These components are designed for general-purpose visual signaling across multiple industries. The product line emphasizes reliability and consistent optical performance for mass-produced electronic equipment.

Replacement Considerations

Direct substitutes include other 0603 red LEDs from different manufacturers with matching electrical characteristics. Ensure replacement parts share the same 2.1V forward voltage and 623nm dominant wavelength. Verify mechanical compatibility regarding pad layout and reflow soldering profiles. Check if alternative suppliers offer equivalent packaging quantities.
