Overview
The B1931USD-20D000814U1930 is a red diffused surface-mount LED manufactured by Harvatek Corporation. 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 peak wavelength of 632nm with a main wavelength of 624nm. Typical forward voltage is 2V at a test current of 20mA. Luminous intensity is rated at 71.5mcd, and it offers a wide viewing angle of 125 degrees.
Feature Summary
- Diffused red lens design for uniform light distribution
- Surface-mount construction in a compact 0603 footprint
- Wide 125-degree viewing angle for broad visibility
Applications
- Panel indicator lights
- Status indication on electronic devices
- Backlighting applications requiring diffuse illumination
Procurement Notes
Verify the specific ordering suffix to ensure correct binning and packaging configuration. Confirm RoHS compliance status and moisture sensitivity level (MSL 2A) requirements for your assembly process. Check lead time availability as standard delivery may vary. Ensure compatibility with your pick-and-place equipment regarding the 0603 package dimensions.
Selection Notes
Select this component when a red indicator with high visibility is required in space-constrained designs. The 0603 package allows for dense PCB layouts. Consider the 2V forward voltage drop for power budget calculations. The diffused lens is suitable where glare reduction is necessary compared to clear lenses.
Part Context
This part belongs to Harvatek's discrete LED indicator series. It is designed for general-purpose signaling in consumer electronics and industrial equipment. The 0603 form factor is a standard industry size, facilitating integration into various board designs without requiring custom footprints.
Replacement Considerations
Direct substitutes must match the 0603 package, red color, and similar electrical characteristics. Verify pinout compatibility if replacing with different manufacturers. Ensure luminous intensity and viewing angle meet the original design specifications.
