B1931NB--20C007614U1930

Overview

The B1931NB--20C007614U1930 is a blue surface-mount LED from Harvatek Corporation, designed for discrete indication applications. It features a 0603 (1608 Metric) package with dimensions of 1.60mm length, 0.80mm width, and a maximum height of 0.50mm. The component emits light at a dominant wavelength of 470nm with a typical forward voltage of 3.3V. Tested at 20mA, it offers viewing angles of 125° and 135°. The lens is clear and colorless, ensuring high-intensity illumination suitable for compact electronic designs requiring reliable visual signaling.

Feature Summary

• High-intensity blue emission optimized for clear visibility in small form factors
• Surface mount construction compatible with standard SMD assembly processes
• Wide viewing angles facilitate effective light distribution across multiple directions

Applications

• Discrete status indication on printed circuit boards
• Visual signaling in consumer electronics devices
• Panel indicator lights for control interfaces

Procurement Notes

Verify the specific suffix matches the required electrical characteristics before ordering. Confirm that the 0603 package dimensions align with the PCB footprint design. Ensure compatibility with reflow soldering profiles specified in the datasheet. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a blue indicator is required within strict spatial constraints defined by the 0603 package size. Consider the 3.3V forward voltage drop for power supply calculations. Evaluate the 125° and 135° viewing angles against the intended line-of-sight requirements. Compare luminous intensity needs against other available colors in the B1931 series.

Part Context

This part belongs to the B1931 series of surface-mount LEDs manufactured by Harvatek Corporation. The series includes various colors such as amber and blue, all sharing similar physical dimensions. The B1931NB variant specifically denotes the blue emission type. These components are designed for automated placement and are commonly used in modern electronics manufacturing.

Replacement Considerations

Direct substitutes within the same series include B1931UY--20D000114U1930 for amber variants. Verify pinout and thermal characteristics when cross-referencing with other manufacturers' 0603 blue LEDs. Ensure equivalent forward voltage and current ratings to maintain circuit performance.
