Overview
The B1591USD-20C001922U1930 is a discrete red light-emitting diode manufactured by Harvatek Corporation. It operates at a forward voltage of 2V and emits light with a peak wavelength of 632nm and a main wavelength of 624nm. The component utilizes a reverse-mount configuration within a 1206 (3216 Metric) surface-mount package, measuring 3.20mm in length, 1.60mm in width, and a maximum height of 1.95mm. It features a round lens with a domed top style.
Feature Summary
- Reverse-mount construction for enhanced environmental protection
- Discrete red LED emission optimized for indicator applications
Applications
- Status indicators
- Direct-view panels
- Backlighting
Procurement Notes
Verify the specific datasheet version when sourcing this component, as reverse-mount variants may have distinct handling requirements compared to standard top-view LEDs. Confirm that the 1.95mm maximum height aligns with the target PCB assembly constraints. Ensure compatibility with reflow soldering profiles suitable for the 1206 metric footprint and the specified moisture sensitivity level.
Selection Notes
Select this part when a low-profile red indicator is required but space allows for the slightly taller reverse-mount profile. It serves as a direct alternative to standard top-view 1206 red LEDs where improved durability against environmental factors is prioritized over minimal height. Ensure the circuit design accounts for the 2V forward voltage drop typical of this red spectrum device.
Part Context
This component belongs to the Harvatek Corporation SMD LED portfolio, specifically designed for compact electronic layouts. It complements other series such as the B1101 and B1501, offering specialized reverse-mount technology. This configuration distinguishes it from standard surface-mount LEDs by providing better protection against external environmental factors while maintaining the familiar 1206 footprint dimensions.
Replacement Considerations
Standard top-view 1206 red LEDs are functionally similar but lack the reverse-mount protective structure. Verify if the increased height of 1.95mm fits the mechanical envelope. No direct cross-model substitutes are explicitly confirmed in public documentation; consult manufacturer guidelines for equivalent reverse-mount alternatives.
