B1931UYG-20D000314U1930

Overview

The B1931UYG-20D000314U1930 is a yellow-green diffused surface-mount LED manufactured by Harvatek Corporation. It operates at a forward voltage of 2.1V with a test current of 20mA, emitting light at a peak wavelength of 573nm and a dominant wavelength of 571nm. The component features a rectangular lens with a flat top and offers a viewing angle of 125 degrees. It provides an intensity of 45mcd and is housed in a 0603 (1608 metric) package measuring 1.60mm in length, 0.80mm in width, and a maximum height of 0.50mm.

Feature Summary

• Diffused yellow-green emission for uniform visual indication
• Surface-mount construction in a compact 0603 footprint
• Wide 125-degree viewing angle for enhanced visibility

Applications

• Electronic device status indicators
• Panel-mounted signal lights
• Consumer appliance control interfaces

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging formats such as tape and reel or cut tape. Confirm RoHS compliance and moisture sensitivity level classifications prior to integration into manufacturing processes. Cross-reference manufacturer part numbers against distributor codes to prevent procurement errors during sourcing.

Selection Notes

Select this component when a low-profile surface-mount indicator is required for space-constrained designs. Ensure circuit design accommodates the 2.1V forward voltage drop at standard operating currents. Consider the diffused lens characteristics for applications requiring broad, non-directional illumination rather than focused beam output.

Part Context

This component belongs to the Harvatek Corporation discrete LED product line, designed for general-purpose signaling within electronic assemblies. It utilizes standard SMD mounting techniques compatible with automated pick-and-place equipment. The 0603 form factor allows for high-density PCB layouts while maintaining reliable optical performance for user interface feedback.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers with matching electrical and mechanical specifications.
