MPR3PGD LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPR3PGD is a panel-mounted LED indicator manufactured by Bivar Inc., featuring a green diffused lens with 555nm peak wavelength and 5mcd brightness rating. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The MPR3PGD operates at 2.2V forward voltage with 30mA maximum current and is housed in a 3mm T-1 round lens package with domed top, designed for 0.24" (6.10mm) round panel cutouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPR3PGD is determined by strict alignment with the following critical and important parameters:

Critical Parameters (Must Match Exactly):

• Lens Size: 3mm, T-1
• Panel Cutout Shape: Round
• Panel Cutout Dimensions: 0.24" (6.10mm)
• Lens Style: Round with Domed Top
• Lamp Color: Green
• Lens Transparency: Diffused

Important Parameters (Must Be Compatible):

• Voltage (Typ): 2.2V ±0.1V tolerance acceptable for circuit compatibility
• Current (Max): 30mA (exact match required)
• Viewing Angle: 35° (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variation Parameters:

• Millicandela Rating: Higher brightness ratings are acceptable if circuit design permits
• Wavelength - Peak: Minor shifts within green spectrum acceptable if visual function is maintained
• Product Status: Active substitutes preferred over obsolete parts

The MPR3GD qualifies as a direct substitute based on matching all critical parameters and maintaining compatibility with important electrical and optical specifications.

Engineering Selection Recommendations

Primary Substitute: MPR3GD

The MPR3GD is the qualified substitute for the obsolete MPR3PGD. Selection is based on the following engineering criteria:

1. Mechanical Compatibility: All physical dimensions, panel cutout specifications, and lens form factors are identical, ensuring direct mechanical interchangeability without panel redesign.

2. Electrical Compatibility: Forward voltage differs by 0.1V (2.1V vs. 2.2V), which is within acceptable tolerance for standard LED circuit designs. Maximum current rating remains 30mA, maintaining identical circuit protection requirements.

3. Optical Compatibility: Viewing angle is identical at 35°. Peak wavelength shifts from 555nm to 568nm, both within the green spectrum. The MPR3GD provides increased brightness (25mcd vs. 5mcd), which enhances visibility without compromising function.

4. Product Status: The MPR3GD is active and in production, ensuring long-term availability and supply chain stability compared to the obsolete MPR3PGD.

5. Regulatory Compliance: The MPR3GD carries ROHS3 and REACH certifications, meeting current environmental and regulatory requirements for new designs and production.

6. Inventory Availability: The MPR3GD has 1569 units in stock, providing immediate procurement capability.

Frequently Asked Questions (FAQ)

Q: Can the MPR3GD be used as a direct replacement for the MPR3PGD without circuit modification?

A: Yes. The MPR3GD is mechanically and electrically compatible with the MPR3PGD. The 0.1V forward voltage difference (2.1V vs. 2.2V) does not require circuit redesign for standard LED indicator applications. Both components operate at 30mA maximum current and fit identical 0.24" (6.10mm) round panel cutouts.

Q: What is the difference in brightness between the two parts?

A: The MPR3GD provides 25mcd brightness compared to the MPR3PGD's 5mcd rating. This represents a 5x increase in luminous intensity. The higher brightness improves visibility and indicator conspicuity without affecting electrical compatibility or circuit operation.

Q: Are there any wavelength differences between the MPR3PGD and MPR3GD?

A: Yes. The MPR3PGD has a peak wavelength of 555nm, while the MPR3GD is rated at 568nm. Both wavelengths fall within the green spectrum and produce visually similar green light. The 13nm difference is not perceptible to human vision in typical indicator applications.

Q: Is the MPR3GD suitable for new product designs?

A: Yes. The MPR3GD is an active product with current production status, ROHS3 compliance, and REACH certification. It is the appropriate choice for new designs requiring a green diffused LED panel indicator in the 3mm T-1 form factor.

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

A: The MPR3PGD packaging is listed as "-" (not specified). The MPR3GD is supplied in Tray packaging. Tray packaging is standard for component handling and automated assembly processes.

Q: Can the MPR3GD be used in applications requiring the exact 555nm wavelength of the MPR3PGD?

A: The MPR3GD operates at 568nm, a 13nm shift toward the yellow-green portion of the spectrum. For applications with strict wavelength requirements, this difference must be evaluated against specific optical or color-matching specifications. For standard green indicator applications, the wavelength difference is not functionally significant.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both the MPR3PGD and MPR3GD have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special humidity control measures.

Q: Is the MPR3GD available in stock?

A: Yes. The MPR3GD has 1569 units in stock as new original components, providing immediate availability for procurement and assembly.
