MPR3RT LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR3RT is a red LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with wire termination. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing procurement and design requirements. The MPR3RT operates at 2.1V forward voltage with a maximum current rating of 20mA, featuring a 3mm T-1 lens form factor with 2.5mcd luminous intensity at 700nm peak wavelength.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MPR3RT is based on electrical and mechanical parameter compatibility within the MPR3 series. The primary substitute, MPR3RD, maintains identical specifications across the following critical parameters:

• Lamp color: Red
• Peak wavelength: 700nm
• Forward voltage: 2.1V
• Maximum current: 20mA
• Lens size: 3mm, T-1
• Panel cutout dimensions: 0.24" (6.10mm)
• Panel cutout shape: Round
• Viewing angle: 20°
• Lens style: Round with Domed Top
• Moisture sensitivity level: 1 (Unlimited)

The MPR3RD differs from the MPR3RT in lens transparency (diffused versus clear) and millicandela rating (2mcd versus 2.5mcd). These differences represent acceptable substitution parameters when optical diffusion and luminous intensity variation are compatible with the application requirements.

Parameter Comparison

Engineering Selection Recommendations

The MPR3RD is the direct substitute for the obsolete MPR3RT based on electrical and mechanical compatibility. The MPR3RD is currently in active production status, ensuring long-term availability and supply chain continuity. The substitute maintains identical electrical ratings (2.1V forward voltage, 20mA maximum current) and mechanical form factor (3mm T-1 lens, 0.24" panel cutout).

The MPR3RD carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to environmental and hazardous substance restrictions. The diffused lens transparency of the MPR3RD produces a 0.5mcd reduction in luminous intensity compared to the clear lens MPR3RT (2mcd versus 2.5mcd). This difference is acceptable for applications where optical diffusion is compatible with visibility requirements.

Frequently Asked Questions (FAQ)

Q: Can the MPR3RD directly replace the MPR3RT in existing designs?

A: The MPR3RD is electrically and mechanically compatible with the MPR3RT. Both components share identical forward voltage (2.1V), maximum current (20mA), lens size (3mm T-1), and panel cutout dimensions (0.24" / 6.10mm). The primary difference is lens transparency: the MPR3RD features a diffused lens compared to the clear lens of the MPR3RT, resulting in a 0.5mcd reduction in luminous intensity (2mcd versus 2.5mcd). Substitution is appropriate when diffused optical characteristics and the specified luminous intensity are compatible with application requirements.

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

A: Clear lens transparency provides direct light transmission with minimal scattering, resulting in higher luminous intensity in the specified viewing angle. Diffused lens transparency scatters light across a broader area, reducing peak intensity but improving visibility from off-axis viewing positions. The MPR3RT (clear) achieves 2.5mcd, while the MPR3RD (diffused) achieves 2mcd at the same forward voltage and current.

Q: Are there packaging differences between the MPR3RT and MPR3RD?

A: The MPR3RD is supplied in tray packaging. Packaging specifications for the MPR3RT are not provided in the available documentation. Confirm packaging requirements with procurement specifications before finalizing component selection.

Q: What regulatory compliance does the MPR3RD provide?

A: The MPR3RD is ROHS3 compliant and REACH unaffected. Both the MPR3RT and MPR3RD are classified under ECCN EAR99 and HTSUS 8541.41.0000. Verify regulatory requirements for your specific application and jurisdiction.

Q: Is the MPR3RD currently available?

A: The MPR3RD is in active production status with 740 pieces in current inventory. The MPR3RT is obsolete. For new designs or ongoing procurement, the MPR3RD is the recommended selection.
