5977761202F

Overview

The Dialight 5977761202F is a surface-mount bi-color LED indicator featuring green and orange emission. It utilizes a 4-SMD (4-PLCC) package with dimensions of approximately 3.10 mm in length, 2.80 mm in width, and a maximum height of 2.05 mm. The device emits at peak wavelengths of 565 nm for green and 624 nm for orange, with dominant wavelengths of 570 nm and 625 nm respectively. Typical forward voltages are 2.1 V for the green element and 1.9 V for the orange element. The luminous intensity is rated at 16 mcd for both colors, tested at a forward current of 20 mA. It offers a wide viewing angle of 120 degrees and operates within an industrial temperature range.

Feature Summary

• Bi-color configuration providing distinct green and orange indication in a single compact component
• High visibility with a 120-degree viewing angle and non-diffused clear lens
• Designed for surface-mount assembly using a standard 4-PLCC footprint

Applications

• Panel status indicators for electronic equipment
• Power supply state signaling
• Industrial control system visual alerts

Procurement Notes

Verify the specific suffix 'F' to confirm tape-and-reel packaging orientation and lead frame composition. Confirm RoHS compliance status as manufacturing sites may vary. Check moisture sensitivity level (MSL) ratings before storage to ensure proper handling procedures are followed during assembly. Validate that the 4-PLCC pinout matches the target PCB footprint design requirements.

Selection Notes

Select this component when dual-color status indication is required in space-constrained applications. The 4-PLCC package allows for automated pick-and-place mounting. Ensure the driving circuit can accommodate the different forward voltage drops between the green and orange elements. Consider the 16 mcd intensity sufficient for direct line-of-sight visibility without additional optics.

Part Context

This part belongs to the Dialight MicroLED series, which focuses on small-form-factor surface-mount LEDs. The 597776 series specifically targets bi-color applications requiring high reliability in industrial environments. It serves as a discrete indicator solution replacing through-hole components in modern PCB designs.

Replacement Considerations

Direct substitutes include other 4-PLCC bi-color LEDs from Dialight such as the 5977721202F (Green/Yellow). Verify wavelength compatibility if color distinction is critical. Cross-reference pin assignments and mechanical dimensions with alternative manufacturers like Broadcom or Everlight.
