MPC3RT LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPC3RT is a red LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with wire termination. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing procurement and design requirements. The MPC3RT operates at 2.1V forward voltage with a maximum current rating of 20mA, delivering 2.5mcd luminous intensity at a 700nm peak wavelength with a 20° viewing angle.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPC3RT is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Manufacturer series (MPC3)
• Lamp color (Red)
• Forward voltage (2.1V)
• Maximum current (20mA)
• Lens size (3mm, T-1)
• Panel cutout dimensions (0.24" / 6.10mm)
• Peak wavelength (700nm)
• Viewing angle (20°)

The MPC3RD qualifies as a substitute part because it maintains all critical electrical parameters and mechanical form factors. The primary difference is the lens transparency specification: MPC3RT features a clear lens, while MPC3RD features a diffused lens. This optical difference results in a reduced millicandela rating (2mcd versus 2.5mcd) but does not affect electrical compatibility or panel mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MPC3RD is an active product substitute for the obsolete MPC3RT. Both components share identical electrical ratings (2.1V, 20mA) and mechanical specifications (3mm T-1 lens, 0.24" panel cutout). The MPC3RD is ROHS3 compliant and REACH unaffected, providing regulatory compliance for new designs.

The optical difference between the parts—clear lens (MPC3RT) versus diffused lens (MPC3RD)—results in different light distribution characteristics. The MPC3RT delivers 2.5mcd with a 20° viewing angle through a clear lens, while the MPC3RD delivers 2mcd through a diffused lens. This 0.5mcd reduction in peak intensity is a direct consequence of the diffusion material and does not indicate a component failure or degradation.

Selection between these parts depends on the specific optical requirements of the application. If the original design specified the clear lens characteristic of the MPC3RT, the diffused lens of the MPC3RD may alter the visual appearance and light distribution in the final assembly.

Frequently Asked Questions (FAQ)

Q: Can the MPC3RD directly replace the MPC3RT in existing designs?

A: The MPC3RD is electrically and mechanically compatible with the MPC3RT. Both components operate at 2.1V, 20mA and mount in identical 0.24" (6.10mm) panel cutouts. However, the optical characteristics differ due to lens transparency differences. The MPC3RD uses a diffused lens, which distributes light over a wider area at reduced peak intensity (2mcd versus 2.5mcd), compared to the clear lens of the MPC3RT.

Q: What is the difference between a clear lens and a diffused lens?

A: The MPC3RT features a clear lens that provides focused light output with higher peak intensity (2.5mcd) concentrated within the 20° viewing angle. The MPC3RD features a diffused lens that scatters light more broadly, resulting in lower peak intensity (2mcd) but more uniform light distribution across the viewing area.

Q: Are there packaging differences between MPC3RT and MPC3RD?

A: The MPC3RT packaging is listed as "-" (not specified in available data). The MPC3RD is supplied in Tray packaging. Both components feature wire termination for panel-mount applications.

Q: What is the product status significance?

A: The MPC3RT is classified as obsolete, indicating it is no longer manufactured or supported by Bivar Inc. The MPC3RD is classified as active, meaning it is currently in production and available for procurement. For new designs or ongoing production requiring red LED panel indicators in the MPC3 series, the MPC3RD represents the current active equivalent.

Q: Are both parts RoHS compliant?

A: The MPC3RD is explicitly stated as ROHS3 compliant. RoHS compliance status for the MPC3RT is not provided in the available technical data.
