5973901831F

Overview

The Dialight 5973901831F is a surface-mount white LED from the 597 series, designed for discrete indication. It features a rectangular lens with a flat top and measures 1.10mm x 0.80mm. The component operates at a typical forward voltage of 3.1V to 3.4V with a test current of 10mA. It delivers a millicandela rating of 176mcd to 240mcd. The device is moisture sensitive (MSL Level 3) and complies with RoHS3 standards.

Feature Summary

• Compact microLED form factor suitable for space-constrained PCB layouts
• Rectangular lens geometry with a flat top surface for directional light emission
• Compliance with RoHS3 environmental regulations

Applications

• Board status indication in consumer electronics
• Power state signaling in industrial control modules
• Signal illumination in compact medical devices

Procurement Notes

Verify the specific datasheet revision and binning classification prior to ordering, as optical intensity can vary within specified tolerances. Confirm that the receiving facility has adequate ESD protection and moisture barrier handling procedures, given the MSL Level 3 rating. Ensure the design accounts for the standard tape and reel packaging dimensions to match automated pick-and-place equipment requirements.

Selection Notes

Select this component when a low-profile white indicator is required for high-density assemblies. The 1.10mm x 0.80mm footprint allows for tighter pitch arrangements compared to standard 0805 packages. Consider the 176mcd to 240mcd output range against ambient lighting conditions to ensure visibility without excessive power consumption or thermal load on the substrate.

Part Context

This part belongs to the Dialight 597 series of microLEDs, which are engineered for applications demanding minimal board space. The series offers various colors and intensities in standardized small-footprint packages. The 5973901831F specifically addresses the need for white illumination in modern miniaturized electronic devices where traditional through-hole or larger SMD LEDs cannot fit.
