5977721502F

Overview

Dialight 5977721502F is a bi-color surface-mount LED indicator featuring green and yellow elements in a 4-SMD, no-lead package. The device emits at peak wavelengths of 570nm (green) and 585nm (yellow), with dominant wavelengths of 575nm and 589nm respectively. It operates with a forward voltage of 2.2V for the green element and 2.1V for the yellow element, tested at 20mA each. Luminous intensity is rated at 21mcd for green and 10mcd for yellow. The component offers a 100-degree viewing angle with a clear, non-diffused lens style.

Feature Summary

• Dual-element configuration providing independent green and yellow light output within a single compact footprint.
• Clear lens design ensures high visibility and precise directional indication without light diffusion.
• Surface-mount construction facilitates automated placement and integration into dense circuit board layouts.

Applications

• Status indication on electronic control panels
• Power state signaling in industrial equipment
• Signal monitoring in telecommunications hardware

Procurement Notes

Verify current manufacturing status as this part may be obsolete. Confirm exact binning requirements for luminous intensity and wavelength consistency. Ensure compatibility with reflow soldering profiles specified for the 4-SMD package. Check for RoHS3 compliance documentation if required by your assembly standards.

Selection Notes

Choose this component when space constraints require a dual-color indicator in a small SMD form factor. Consider the specific forward voltage drops for driver circuit design. Evaluate the 100-degree viewing angle against panel mounting requirements. Compare luminous intensity ratings with ambient lighting conditions to ensure adequate visibility.

Part Context

This component belongs to Dialight's microLED series, designed for surface-mount applications requiring reliable visual signaling. The 5977721502F variant specifically combines green and yellow emissions in a standardized 4-pin SMD package, aligning with industry trends toward miniaturized optoelectronic indicators.

Replacement Considerations

The manufacturer recommends 5977721207F as a replacement. Verify electrical parameters and mechanical dimensions before substitution. Ensure the alternative maintains compatible pinout and thermal characteristics for existing PCB designs.
