MPR3PGT LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR3PGT is a green LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with wire termination. This component is classified as obsolete, indicating it is no longer in active production. The MPR3PGT features a 555nm peak wavelength green LED with 10mcd brightness rating, 2.2V forward voltage, and 30mA maximum current rating, housed in a 3mm T-1 round domed lens package with clear transparency and 20° viewing angle.

Due to its obsolete status, sourcing replacement units may present supply chain challenges. Identifying equivalent substitute parts ensures design continuity and maintains component availability for maintenance, repair, and production applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPR3PGT are identified based on strict compatibility criteria within the MPR3 series from Bivar Inc. The substitution logic is based on the following allowed parameters:

Mechanical Compatibility:

• Panel cutout shape must be round
• Panel cutout dimensions must be 0.24" (6.10mm)
• Lens size must be 3mm, T-1
• Lens style must be round with domed top
• Termination must support wire connection

Electrical Compatibility:

• Maximum current rating must be 30mA
• Forward voltage must be within acceptable operating range (2.1V to 2.2V)

Optical Compatibility:

• Lamp color must be green
• Lens color must be green
• Product must be from the same MPR3 series

Environmental Compatibility:

• Moisture Sensitivity Level must be 1 (Unlimited)

The MPR3GD meets all mechanical, electrical, and environmental compatibility criteria and is classified as an active product with current manufacturing status.

Engineering Selection Recommendations

Primary Substitute: MPR3GD

The MPR3GD is the qualified substitute for the obsolete MPR3PGT based on the following engineering criteria:

Product Status Advantage: The MPR3GD is classified as active product in current production, ensuring reliable long-term availability compared to the obsolete MPR3PGT. This status eliminates supply chain risk for ongoing applications.

Mechanical Compatibility: Both parts share identical mechanical specifications: 3mm T-1 round domed lens, round panel cutout shape, and 0.24" (6.10mm) panel cutout dimensions. Direct mechanical interchangeability is confirmed for panel-mount applications.

Electrical Compatibility: Forward voltage differs by 0.1V (2.2V vs. 2.1V), which is within standard LED tolerance ranges and does not affect circuit design compatibility. Maximum current rating is identical at 30mA, ensuring equivalent power dissipation characteristics.

Compliance Status: Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming equivalent regulatory and trade compliance. The MPR3GD is ROHS3 compliant and REACH unaffected, meeting modern environmental standards.

Optical Differences: The MPR3GD exhibits higher brightness (25mcd vs. 10mcd), wider viewing angle (35° vs. 20°), and diffused lens transparency compared to the clear lens of the MPR3PGT. Peak wavelength differs by 13nm (568nm vs. 555nm). These optical differences represent performance enhancements rather than incompatibilities and may improve visibility in panel-mount indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the MPR3GD directly replace the MPR3PGT in existing designs?

A: Yes. The MPR3GD provides direct mechanical and electrical interchangeability. Both parts feature identical panel cutout dimensions (0.24"/6.10mm), lens size (3mm T-1), and maximum current rating (30mA). Forward voltage differs by only 0.1V, which is within standard LED operating tolerances and does not require circuit modification.

Q: What are the optical differences between these parts?

A: The MPR3GD features a diffused lens compared to the clear lens of the MPR3PGT. The MPR3GD also provides higher brightness (25mcd vs. 10mcd), a wider viewing angle (35° vs. 20°), and a slightly longer peak wavelength (568nm vs. 555nm). These differences represent optical enhancements that may improve indicator visibility without affecting functional compatibility.

Q: Why is the MPR3PGT listed as obsolete?

A: The MPR3PGT is no longer in active production by Bivar Inc. The MPR3GD serves as the active production equivalent within the same MPR3 series, offering improved specifications and current manufacturing availability.

Q: Are there packaging differences between these parts?

A: The MPR3PGT packaging is listed as unspecified in available documentation. The MPR3GD is supplied in tray packaging. Both parts share identical component specifications and panel-mount mechanical requirements.

Q: Do both parts meet current environmental compliance standards?

A: Both parts carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). The MPR3GD is explicitly ROHS3 compliant and REACH unaffected, confirming compliance with current environmental regulations. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the current inventory status?

A: The MPR3PGT has 771 pieces in stock as new original inventory. The MPR3GD has 1,569 pieces in stock as new original inventory, providing superior availability for ongoing procurement.

Q: Will the higher brightness of the MPR3GD affect my circuit design?

A: No. Both parts operate at identical maximum current (30mA) and share compatible forward voltage specifications (2.2V vs. 2.1V). The increased brightness of the MPR3GD results from improved LED efficiency, not increased current draw. Existing circuit designs require no modification.
