BL-B31V1-AT

Overview

The BL-B31V1-AT is a single-color yellow LED from the BL-B series, manufactured by American Bright Optoelectronics Corporation. It features a T-1 (3 mm) dome lens with diffused appearance and radial mounting. Key electrical parameters include a peak wavelength of 595 nm, forward voltage of 2.1 V at 20 mA, and luminous intensity of 45 mcd. The component operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Utilizes GaAsP/GaP chip material for efficient yellow light emission
• Features a low power consumption design suitable for indicator applications
• Includes bin-sorted performance for consistent optical characteristics

Applications

• Panel indicators
• Status indication
• Control equipment signaling

Procurement Notes

Verify the specific datasheet version for the BL-B31V1-AT to confirm current electrical tolerances and mechanical dimensions. Ensure compatibility with existing circuit designs regarding forward voltage and current requirements. Cross-reference manufacturer part numbers to avoid confusion with similar models in the BL-B series.

Selection Notes

Select this component when a standard 3 mm yellow LED with moderate intensity is required. The 2.1 V forward voltage suits low-voltage logic circuits. Consider the diffused lens for wider viewing angles compared to clear variants. Verify thermal management needs against the specified operating temperature range.

Part Context

This model belongs to the BL-B series of low-current LED lamps designed for general indication purposes. American Bright Optoelectronics Corporation produces these components as part of their standard discrete LED lineup, focusing on reliability and cost-effectiveness for mass-produced electronic devices.

Replacement Considerations

Direct substitutes may include other 3 mm yellow LEDs with similar forward voltage and intensity ratings. Verify pin configuration and lens diameter before replacement. Check if alternative manufacturers offer equivalent spectral output and mechanical fit.
