BL-B2141

Overview

The BL-B2141 is a green diffused LED lamp in a T-1 (3mm) through-hole package. It features a round lens with a domed top and standard 1.0-inch leads. Key electrical parameters include a typical forward voltage of 2.2V at a test current of 20mA. Optical characteristics specify a dominant wavelength of 567nm and a light intensity of 30mcd. The component utilizes GaP/GaP chip material and operates within a temperature range defined by the manufacturer's standard specifications.

Feature Summary

• Green emission with diffused lens transparency for broad visibility
• Standard T-1 3mm axial leaded form factor for easy mounting
• GaP semiconductor material construction

Applications

• General purpose panel indicator lights
• Power status indication on electronic equipment
• Control board visual signaling

Procurement Notes

Verify the specific suffix variant when ordering, as American Bright uses suffixes to denote optical or electrical tolerances. Confirm that the required wavelength and intensity meet your design specifications, as values may vary between sub-models. Check RoHS compliance status directly with the manufacturer or authorized distributors, as historical batches may differ. Ensure the through-hole footprint matches your PCB layout requirements.

Selection Notes

Select this component for applications requiring a standard 3mm green indicator with moderate brightness. Consider the 2.2V forward voltage drop when designing the current-limiting resistor circuit. The diffused lens provides a softer light output compared to clear variants, which may be preferable for reducing glare in user interfaces. Verify availability of the specific suffix version required for your tolerance needs.

Part Context

This part belongs to the BL-B series of low-current LED lamps from American Bright Optoelectronics Corporation. The series includes various colors and lens styles, all sharing the standard T-1 3mm physical dimensions. These components are designed for general indication purposes rather than high-intensity illumination.

Replacement Considerations

Direct substitutes include other 3mm green diffused LEDs with similar 2.2V forward voltage and 567nm wavelength. Verify mechanical compatibility of the lead spacing and lens diameter before substitution.
