5977741202F

Overview

The Dialight 5977741202F is a surface-mount bi-color LED indicator featuring green and orange emission. It utilizes a 4-pin PLCC package with circular, non-diffused lenses. The component operates within an industrial temperature range of -55°C to 100°C. Key electrical parameters include a forward voltage of 2.1V for the green element and 2.0V for the orange element, tested at 20mA. Peak wavelengths are specified at 565nm for green and 625nm for orange. Luminous intensity is rated at 16mcd per color. The device has a viewing angle of 120 degrees and measures 3.10mm in length, 2.80mm in width, and 2.05mm in height.

Procurement Notes

Verify the specific part number against manufacturer documentation to confirm current production status and availability. Ensure that the selected variant matches the required pin configuration and lens type for your PCB layout. Cross-reference datasheet specifications for forward voltage and luminous intensity to guarantee compatibility with your drive circuitry. Confirm compliance with relevant environmental regulations such as RoHS prior to final procurement decisions.

Selection Notes

Select this component when a dual-color indication is required within a limited board space. The 4-PLCC form factor suits automated surface-mount assembly processes. Consider the 120-degree viewing angle for applications requiring broad visibility. Verify that the operating temperature range aligns with the environmental conditions of the end-use application to ensure long-term reliability.

Part Context

This component belongs to the Dialight MicroLED series, which focuses on providing flexible lighting solutions in discrete packages. The 597 series represents a line of standard surface-mount LEDs designed for general-purpose indication. These devices offer a balance of performance and size, suitable for modern electronics manufacturing where space efficiency is critical.

Replacement Considerations

Consult official distributor databases for confirmed substitute part numbers. Verify mechanical dimensions and pin assignments before substitution.
