BL-BUF4V4V

Overview

The BL-BUF4V4V is a single-color red LED from the BL-B series, manufactured by American Bright Optoelectronics Corporation. It features a T-1 3/4 (5mm) radial package with a clear lens and domed top. The component emits at a dominant wavelength of 631nm with a typical forward voltage of 2.1V. It operates at a forward current of 20mA, delivering a millicandela rating of 1300mcd. The device has a power rating of 80mW and is designed for low-current applications.

Feature Summary

• Utilizes GaAsP/GaP chip material for high efficiency
• Features a water clear lens for precise light direction
• Designed for low power consumption and low current requirements
• Supports versatile mounting on printed circuit boards or panels

Applications

• Panel indicator lights
• Discrete indication in electronic devices
• Low-power status signaling
• General purpose illumination

Procurement Notes

Verify supplier confirmation regarding RoHS compliance status, as documentation indicates it may be unconfirmed. Ensure the specific ordering suffix matches the required lens transparency and color specifications. Cross-reference datasheet parameters such as forward voltage and wavelength against design requirements to confirm compatibility with existing circuit designs.

Selection Notes

Select this component for applications requiring a standard 5mm through-hole red LED with clear optics. Consider the 2.1V forward voltage drop when designing current-limiting resistor networks. The 1300mcd brightness level is suitable for visible indication in ambient lighting conditions. Verify that the radial lead configuration fits the available PCB footprint or panel mount hole diameter.

Part Context

This part belongs to the BL-B series of low-current LED lamps produced by American Bright Optoelectronics Corporation. The series typically includes various colors and lens types within the T-1 3/4 package format. Similar parts in the family include models like BL-B4524, which share the same physical dimensions but may differ in emitted color and lens diffusion characteristics.

Replacement Considerations

Direct substitutes may include other 5mm red LEDs with similar forward voltage and current ratings. Check for compatible packages such as T-1 3/4 radial mounts. Ensure replacement parts maintain the required 631nm wavelength if color consistency is critical. Verify mechanical dimensions match the existing board layout.
