MPR3GT LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR3GT is a panel-mounted LED indicator manufactured by Bivar Inc., designed for applications requiring a green light-emitting diode with clear lens optics. This component features a 3mm T-1 form factor with a round domed top lens, rated at 2.1V forward voltage and 30mA maximum current, delivering 40 millicandela at a 568nm peak wavelength with a 20° viewing angle.

The MPR3GT is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, repair, and continued operation where original stock is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPR3GT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Bivar Inc.
• Series: MPR3
• Type: LED
• Lamp Color: Green
• Lens Color: Green
• Voltage (Vf Typ): 2.1V
• Current (If Max): 30mA
• Panel Cutout Shape: Round
• Panel Cutout Dimensions: 0.24" (6.10mm)
• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Wavelength - Peak: 568nm
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8541.41.0000

Allowable Variation Parameters:

• Lens Transparency: Clear or Diffused
• Millicandela Rating: Within operational range
• Viewing Angle: Within operational range
• Product Status: Active or Obsolete

The MPR3GD qualifies as a substitute because it maintains all mandatory parameters while varying only in lens transparency (Diffused vs. Clear), millicandela rating (25mcd vs. 40mcd), and viewing angle (35° vs. 20°). These variations remain within acceptable operational tolerances for panel-mounted indicator applications.

Parameter Comparison

Engineering Selection Recommendations

MPR3GD as Primary Substitute:

The MPR3GD is the designated substitute for the obsolete MPR3GT. Selection of the MPR3GD is supported by the following factors:

1. Product Status: The MPR3GD maintains Active status, ensuring continued availability and manufacturing support. The MPR3GT is classified as Obsolete, making the MPR3GD the appropriate alternative for ongoing system support.

2. Regulatory Compliance: The MPR3GD carries ROHS3 Compliant and REACH Unaffected certifications, meeting current environmental and regulatory requirements. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

3. Electrical Compatibility: Both components operate at identical voltage (2.1V) and current (30mA) ratings, ensuring direct circuit compatibility without modification to power supply or current-limiting resistor calculations.

4. Mechanical Compatibility: Both components feature identical panel cutout dimensions (0.24" / 6.10mm), lens size (3mm T-1), and lens style (Round with Domed Top), enabling direct mechanical substitution in existing panel assemblies.

5. Optical Characteristics: The MPR3GD operates at 568nm peak wavelength, matching the MPR3GT. The diffused lens transparency and increased viewing angle (35° vs. 20°) provide broader light distribution, while the reduced millicandela rating (25mcd vs. 40mcd) remains suitable for indicator applications where the primary function is status signaling rather than high-intensity illumination.

6. Inventory Availability: The MPR3GD is available in higher quantity (1569 Pcs) compared to the MPR3GT (831 Pcs), supporting both immediate replacement needs and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the MPR3GD directly replace the MPR3GT without circuit modification?

A: Yes. Both components share identical voltage (2.1V) and current (30mA) specifications. No changes to power supply, resistor values, or circuit topology are required.

Q: What is the difference between Clear and Diffused lens transparency?

A: The MPR3GT features a Clear lens, which provides focused light output with a narrow 20° viewing angle and higher intensity (40mcd). The MPR3GD features a Diffused lens, which scatters light across a wider 35° viewing angle with lower intensity (25mcd). Selection depends on application requirements for light distribution and brightness.

Q: Will the MPR3GD fit the same panel cutout as the MPR3GT?

A: Yes. Both components have identical panel cutout dimensions of 0.24" (6.10mm) and round shape, enabling direct mechanical substitution in existing panel assemblies.

Q: Why is the MPR3GT classified as Obsolete?

A: The MPR3GT is no longer in active production. The MPR3GD serves as the active production equivalent within the same MPR3 series.

Q: Does the MPR3GD meet current environmental regulations?

A: Yes. The MPR3GD is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the packaging difference between the two parts?

A: The MPR3GT packaging is listed as "-" (not specified). The MPR3GD is supplied in Tray packaging.

Q: Are there any wavelength differences between the two parts?

A: No. Both components operate at an identical 568nm peak wavelength, ensuring consistent green color output.
