5977731107

Overview

The Dialight 5977731107 is a bi-color surface-mount LED indicator featuring red and yellow emitters in a 4-SMD, no-lead package. It operates with a forward voltage of 2V for the red section and 2.1V for the yellow section. The device emits light at peak wavelengths of 620nm (red) and 585nm (yellow). Designed for board-level indication, it utilizes a clear lens to provide distinct color visibility.

Feature Summary

• Bi-color configuration combining red and yellow LEDs within a single compact footprint
• Clear lens design ensures high transparency and distinct color separation
• Surface-mount construction facilitates automated PCB assembly processes

Applications

• Electronic equipment status indication
• Control panel signal display
• Board-level operational feedback systems

Procurement Notes

Verify the specific manufacturer part number against official Dialight documentation to confirm exact electrical characteristics and pinout configurations. Ensure compatibility with standard reflow soldering profiles for SMD components. Cross-reference datasheets for thermal management requirements during operation.

Selection Notes

Select this component when dual-color status indication is required in space-constrained designs. The low forward voltage suits low-power applications. Evaluate the clear lens option against diffused alternatives based on visibility requirements. Confirm mechanical fit within the target PCB layout constraints.

Part Context

This component belongs to the Dialight discrete LED indicator series, designed for reliable visual signaling in electronic circuits. The 4-SMD form factor represents a modern surface-mount solution replacing older through-hole technologies, offering improved automation compatibility and reduced assembly costs.

Replacement Considerations

Consult official Dialight documentation for verified substitute part numbers. Direct replacements must match the 4-SMD package dimensions, bi-color functionality, and electrical specifications.
