5977701107

Overview

The Dialight 5977701107 is a discontinued bi-color surface mount LED featuring green and red elements in a 4-SMD, no-lead package. It emits at peak wavelengths of 565nm (green) and 630nm (red). The component has a forward voltage of 2V for both colors and operates with a test current of 20mA per element. Luminous intensity is rated at 12mcd for green and 4mcd for red. It utilizes a clear, non-diffused lens with a viewing angle of 170 degrees. Dimensions are 3.00mm length by 2.54mm width, with a maximum height of 1.47mm.

Feature Summary

• Bi-color configuration combining green and red light sources within a single compact surface-mount footprint.
• Clear lens design providing high transparency and a wide 170-degree viewing angle for broad visibility.
• Industrial operating temperature classification suitable for demanding environmental conditions.

Applications

• Panel status indicators requiring distinct color coding for operational states.
• Electronic equipment signaling where space-constrained bi-color indication is necessary.
• Industrial control systems utilizing standard surface-mount assembly processes.

Procurement Notes

This component is officially obsolete and no longer manufactured by Dialight. Procurement must focus on identifying verified substitute parts or exploring secondary market availability. Verify that any replacement matches the original electrical parameters, pinout, and mechanical dimensions to ensure compatibility with existing designs.

Selection Notes

Due to the discontinued status, direct selection is not possible for new designs. Engineers should evaluate alternative bi-color SMD LEDs from the same manufacturer or competitors. Key comparison criteria include matching the 4-SMD package size, ensuring compatible forward voltage and current ratings, and confirming similar luminous intensity requirements for the specific application context.

Part Context

The 5977701107 belongs to Dialight's microLED series, designed for high-density surface-mount applications. This series emphasizes compact form factors while maintaining reliable optical performance. As an obsolete part, it represents a legacy solution previously utilized in various industrial and commercial indicator panels before newer packaging technologies became available.
