5973909202F

Overview

The Dialight 5973909202F is a white surface-mount LED in a PLCC-4 package. It features a clear lens and emits light at a peak wavelength of 610nm, classified as orange in some listings but described as white in others. The component has a typical forward voltage of 3.2V and a maximum forward current of 20mA. Brightness is rated at 900mcd with a viewing angle of 110 degrees. Dimensions are 3.00mm x 2.00mm x 1.30mm max height.

Feature Summary

• Surface mount PLCC-4 package for automated assembly
• Clear lens style for direct visibility
• High brightness output suitable for panel indicators

Applications

• Panel status indication
• Board-level signaling
• Electronic equipment power indicators

Procurement Notes

Verify the specific color designation (white vs. orange) and datasheet version before ordering, as conflicting descriptions exist in public sources. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your manufacturing process. Ensure the PLCC-4 footprint matches your PCB design.

Selection Notes

Select this component for applications requiring a standard PLCC-4 form factor with high luminous intensity. Consider the 110-degree viewing angle for wide-area visibility. Evaluate the 3.2V forward voltage drop against your circuit's supply constraints. Check if the clear lens meets optical clarity requirements compared to diffused alternatives.

Part Context

This part belongs to the Dialight 597 series of surface-mount LEDs. It shares the PLCC-4 package format with other variants in the line, differing primarily in color, wavelength, and lens type. It is designed for general-purpose indicator applications where space efficiency and reliability are prioritized.

Replacement Considerations

Direct substitutes include other PLCC-4 white LEDs from Dialight such as the 5973902507F, though verification of exact electrical parameters and mechanical dimensions is required. Cross-brand replacements must match the 3.0x2.0mm footprint and pin configuration.
