R4HD

LED Indication - Discrete Overview

The Bivar R4HD is a red diffused through-hole LED indicator featuring a rectangular lens measuring 4.00mm x 2.00mm with a flat top style. It operates with a typical forward voltage of 2V and a test current of 20mA, delivering an 8mcd brightness rating. The component offers a 120-degree viewing angle and utilizes radial mounting for PCB integration.

LED Indication - Discrete Feature Summary

• Red diffused light emission within a rectangular form factor
• Through-hole radial mounting configuration
• Flat top lens design for standardized appearance

LED Indication - Discrete Applications

LED Indication - Discrete Procurement Notes

Verify the part status carefully as this specific model may be listed as obsolete in official catalogs. Confirm availability through authorized distributors or secondary markets if direct supply from Bivar Inc. is unavailable. Ensure compatibility with existing assembly processes before procurement.

LED Indication - Discrete Selection Notes

Select this component when a low-profile red indicator with specific dimensional constraints is required. The 2V forward voltage suits lower voltage logic circuits. Consider the 120-degree viewing angle for visibility requirements and verify that the rectangular footprint aligns with the target PCB layout.

LED Indication - Discrete Part Context

This discrete LED belongs to Bivar Inc.'s broader portfolio of LED indication products designed for PCB positioning and enclosure signaling. It complements their range of rigid light pipes and other discrete indicators, serving as a specialized solution for visual status feedback in electronic assemblies.

LED Indication - Discrete Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the part status is noted as obsolete, alternative sourcing strategies or redesigning with currently active components from the manufacturer's current lineup is recommended.
