Overview
The B1A81USD-20C000313U1930 is a red 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 red light at a peak wavelength of 632nm and a dominant wavelength of 624nm. It operates with a typical forward voltage of 2V at a test current of 20mA, producing a luminous intensity of 71.5mcd. The lens is diffused with a rectangular shape and flat top, providing a viewing angle of 125 degrees.
Feature Summary
- Diffused red lens design for uniform light distribution
- Compact 0603 surface-mount form factor for space-constrained layouts
- High viewing angle of 125 degrees for wide visibility
Applications
- Status indicators in consumer electronics
- Panel lighting for control interfaces
- Backlighting applications requiring compact components
Procurement Notes
Verify the specific ordering suffix to ensure correct binning and wavelength specifications. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for alternate packaging options such as tape and reel or cut tape based on production volume requirements. Ensure compatibility with standard reflow soldering profiles for SMD components.
Selection Notes
Select this component when a small footprint is required for red indication. The 0603 size suits dense PCB designs. Consider the 125-degree viewing angle for visibility needs. Verify that the 2V forward voltage aligns with the driving circuit capabilities. Ensure the diffused lens meets the aesthetic requirements of the final product.
Part Context
This part belongs to the Harvatek Corporation SMD LED series, which offers various colors and package sizes. The 0603 package is a standard industry size for surface-mount technology. Red LEDs in this category are commonly used for power and status signaling in electronic devices.
Replacement Considerations
Check datasheets for compatible 0603 red LEDs from other manufacturers. Verify pinout compatibility and electrical parameters such as forward voltage and luminous intensity. Ensure mechanical dimensions match the existing PCB footprint to avoid redesign.
