5HDL

Overview

The Bivar Inc. 5HDL is a single-color red LED designed for through-hole mounting in a T-1 3/4 (5 mm) package. It features a diffused dome lens with a wavelength of 635 nm and an optical intensity of 5 mcd. The component operates at a forward current of 2 mA with a forward voltage of 2 V, rated for 10 mW power dissipation.

Feature Summary

• Through-hole installation in a standard 5 mm T-1 3/4 axial leaded package
• Diffused red dome lens provides wide viewing angle illumination
• High-efficiency red emission centered at 635 nm wavelength

Applications

• Panel-mounted status indicators
• Front panel visual signaling
• Control board activity monitoring

Procurement Notes

Verify the obsolete status indicated by the NRND designation before procurement. Confirm that the specific 635 nm wavelength variant matches design requirements, as alternative versions like the 5HDL-F exist with different specifications. Ensure supply chain sources provide authentic components from authorized distributors to avoid counterfeit parts.

Selection Notes

Select this component when a standard 5 mm through-hole red indicator is required for general purpose signaling. Consider the 2 mA forward current requirement for circuit design. Evaluate the diffused lens output against visibility needs compared to clear or water-clear alternatives in the same series.

Part Context

This part belongs to Bivar's discrete LED indication category, specifically within the single-color LED subcategory. It utilizes the traditional T-1 3/4 form factor common in legacy and industrial electronics. The product line focuses on reliable visual feedback components for equipment panels.
