5RD-F

Overview

The Bivar Inc. 5RD-F is a single-color red LED indicator designed for through-hole mounting in a T-1 3/4 (5 mm) package. It features a round lens with a domed top and diffused transparency to optimize light distribution. The component emits at a wavelength of 623 nm, providing a clear visual signal. Key electrical parameters include a typical forward voltage of 2.1 V and a test current of 20 mA. The viewing angle is specified at 40 degrees, ensuring focused illumination suitable for panel-mounted applications.

Feature Summary

• Through-hole mounting configuration in a standard T-1 3/4 package
• Diffused lens style with a domed top for optimized light dispersion
• Red emission color with a 40-degree viewing angle

Applications

• Panel-mounted status indicators
• Equipment power state signaling
• Control board visual feedback

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before integration, as manufacturing specifications may evolve. Confirm that the 2.1 V forward voltage aligns with your circuit design limits. Ensure the through-hole footprint matches your PCB layout requirements. Check for any regional supply restrictions or end-of-life notifications associated with this part number prior to finalizing procurement plans.

Selection Notes

Select the 5RD-F when a standard 5 mm through-hole red LED with a diffused finish is required. Its 40-degree viewing angle offers a balance between visibility and directionality. Consider this component for general-purpose indication where a domed lens aesthetic is preferred. Evaluate the 2.1 V forward voltage drop against your available drive voltage to ensure proper operation without excessive current limiting resistance.

Part Context

This component belongs to Bivar's discrete LED indication series, specifically utilizing the T-1 3/4 form factor. It serves as a fundamental optical signaling element within electronic assemblies. The product line focuses on reliable visual feedback for industrial and consumer devices. The 5RD-F variant specifically addresses applications requiring red light emission with standardized mechanical dimensions for easy replacement in existing designs.

Replacement Considerations

Cross-reference with other T-1 3/4 red LEDs from different manufacturers if supply constraints arise. Verify compatibility regarding forward voltage, current ratings, and physical lead spacing. Ensure the replacement part maintains the same diffused lens characteristic and viewing angle to preserve the intended visual performance.
