599-0440-127F

Overview

The Dialight 599-0440-127F is a single-color yellow surface-mount LED in the 599 series. It features a 1206 (3216 Metric) package with non-diffused optics and a water-clear lens. Key electrical parameters include a forward current of 20 mA, a forward voltage of 2.4 V, and a typical wavelength of 590 nm. The component offers a luminous intensity of 630 mcd and a viewing angle of 40 degrees. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Single-color yellow emission with high luminous intensity
• Non-diffused optical design for directional light output
• Standard 1206 surface-mount form factor

Applications

• Board status indication
• Panel indicator lights
• General electronic equipment signaling

Procurement Notes

Verify the specific datasheet version for the 599-0440-127F to confirm RoHS compliance status and SVHC declarations. Ensure that the 1206 package dimensions and soldering thermal profiles align with your PCB assembly capabilities. Cross-reference the 20 mA forward current rating with your circuit design to ensure adequate current limiting components are included.

Selection Notes

Select this component when a bright, directional yellow indicator is required in a compact 1206 footprint. The 590 nm wavelength provides distinct visibility compared to standard red LEDs. Consider the 40-degree viewing angle for applications requiring focused illumination rather than wide-area diffusion. Verify compatibility with automated pick-and-place processes due to the SMD configuration.

Part Context

This part belongs to Dialight's 599 series of MicroLEDs, designed for space-constrained electronics. The series offers various colors and package sizes, with the 599-0440-127F specifically providing yellow light in the 1206 metric case. It serves as a reliable discrete indicator solution for modern printed circuit boards.

Replacement Considerations

Direct substitutes may include other 1206 yellow LEDs from manufacturers such as Kingbright or Vishay, provided they match the 20 mA current, 2.4 V forward voltage, and 590 nm wavelength specifications. Always verify pinout compatibility and mechanical dimensions before substitution.
