Bivar Inc. 5RC LED Red Clear T-1 3/4 Through-Hole Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 5RC is a red LED indicator light featuring a clear, colorless lens with a 5mm T-1 3/4 through-hole radial package. This discrete component provides red indication functionality at 2.1V forward voltage with a 2mcd brightness rating. The 5RC carries an obsolete product status, making it necessary to identify active alternatives that maintain functional and mechanical compatibility with existing designs and assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5RC must meet the following mandatory electrical and mechanical criteria:

Matching Parameters:

• Red LED color (same emission characteristic)
• 2.1V forward voltage (electrical compatibility)
• 20mA test current (design circuit compatibility)
• 5mm T-1 3/4 lens size (physical envelope and form factor)
• Radial through-hole package (board assembly method)
• 8.50mm maximum height (PCB clearance compatibility)
• 700nm peak wavelength (spectral match)
• 2mcd millicandela rating (brightness level)

The substitute part 5RD maintains all electrical parameters and mounting specifications while varying in lens optical characteristics. The 5RD features a red-tinted diffused lens with increased viewing angle (45° versus 35°), making it suitable for applications requiring broader light dispersion from the same component family.

Parameter Comparison

Engineering Selection Recommendations

The 5RD serves as a direct functional substitute for the obsolete 5RC. Both components share identical electrical specifications (2.1V forward voltage, 20mA test current, 2mcd brightness) and mechanical compatibility (5mm T-1 3/4 radial through-hole package, 8.50mm maximum height).

The primary design consideration is the optical difference: the 5RC features a colorless clear lens while the 5RD features a red-tinted diffused lens with a wider viewing angle (45° versus 35°). The 5RD's diffused lens provides broader light distribution, which may alter the visual characteristics of the indicator in the final application. Selection should be based on whether the original circuit design requires the narrower directional beam of the clear lens (5RC) or benefits from the wider, more dispersed light output of the diffused lens (5RD).

The 5RD holds active product status and carries ROHS3 compliance, providing supply chain continuity and regulatory alignment for new designs and production boards.

Frequently Asked Questions (FAQ)

Q: Can the 5RD be used as a direct drop-in replacement for the 5RC? A: Yes, from an electrical and mechanical perspective. Both components have identical forward voltage (2.1V), test current (20mA), package (T-1 3/4 radial through-hole), and board footprint. The primary difference is the lens optical characteristic: clear colorless versus red diffused.

Q: What is the functional difference between clear and diffused lenses? A: The 5RC's clear colorless lens provides a narrower, more directional light beam (35° viewing angle), while the 5RD's red diffused lens disperses light over a wider area (45° viewing angle). Select based on the required light distribution pattern for your application.

Q: Are both parts compatible with existing PCB layouts? A: Yes. Both the 5RC and 5RD are specified at 8.50mm maximum height in the same T-1 3/4 radial through-hole package, ensuring PCB clearance and board assembly compatibility.

Q: What is the inventory status of these parts? A: The 5RC is obsolete with limited remaining stock (828 units). The 5RD is active with 1142 units in inventory, providing reliable supply for ongoing production.

Q: Does the 5RD meet regulatory compliance standards? A: Yes. The 5RD is ROHS3 compliant, meeting current electronic waste directive requirements for new designs.

Q: Are there performance differences in brightness between the two parts? A: Both parts are rated at 2mcd (millicandela), indicating identical brightness output. The optical difference lies in light distribution: the 5RC concentrates light in a narrower beam, while the 5RD disperses the same total light output over a wider viewing angle.
