MPC3PGC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPC3PGC is a green LED panel indicator manufactured by Bivar Inc., designed for panel-mount applications with a 3mm T-1 lens form factor. This component is classified as Obsolete product status. The MPC3PGC features a clear lens with a 20° viewing angle, 10mcd brightness rating, and operates at 2.2V forward voltage with 30mA maximum current. Due to its obsolete status, identifying functionally compatible substitute parts is necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MPC3PGC is determined by the following critical parameters:

Mechanical Compatibility:

• Panel cutout shape and dimensions (Round, 0.24" / 6.10mm)
• Lens size form factor (3mm, T-1)
• Lens style (Round with Domed Top)

Electrical Compatibility:

• Lamp color (Green)
• Maximum current rating (30mA)
• Forward voltage range (2.2V nominal)

Optical Characteristics:

• Wavelength range (555nm peak acceptable range)
• Brightness rating (10mcd minimum acceptable)
• Viewing angle (20° minimum acceptable)

The MPC3GD substitute part maintains identical mechanical specifications and electrical current/voltage parameters within acceptable operating ranges. Both components share the same panel cutout dimensions, lens form factor, and maximum current rating, enabling direct mechanical and electrical substitution in panel-mount applications.

Engineering Selection Recommendations

Primary Substitute: MPC3GD

The MPC3GD is the recommended substitute for the obsolete MPC3PGC based on the following engineering criteria:

Mechanical Compatibility: Both components share identical panel cutout dimensions (0.24" / 6.10mm) and lens form factor (3mm T-1 round domed), ensuring direct mechanical fit in existing panel designs without modification.

Electrical Compatibility: The MPC3GD operates at 2.1V forward voltage compared to the MPC3PGC's 2.2V, representing a 0.1V difference within standard component tolerances. Both components are rated for 30mA maximum current, ensuring compatibility with existing current-limiting circuit designs.

Product Status and Compliance: The MPC3GD holds Active product status, ensuring long-term availability and supply chain continuity. The substitute meets ROHS3 compliance and REACH unaffected status, satisfying modern regulatory requirements that may not have been applicable to the obsolete MPC3PGC.

Optical Performance: The MPC3GD provides enhanced optical characteristics with 25mcd brightness (versus 10mcd) and a 35° viewing angle (versus 20°), offering improved visibility in panel-mount applications. The peak wavelength difference of 13nm (568nm versus 555nm) remains within the green spectrum range and is imperceptible to human vision in typical indicator applications.

Optical Diffusion Consideration: The MPC3GD features a diffused green lens compared to the MPC3PGC's clear colorless lens. This diffusion characteristic affects light distribution and appearance but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MPC3GD directly replace the MPC3PGC in existing designs?

A: Yes. Both components share identical panel cutout dimensions (0.24" / 6.10mm), lens form factor (3mm T-1), and maximum current rating (30mA). The forward voltage difference of 0.1V (2.1V versus 2.2V) is within standard component tolerances and does not require circuit redesign.

Q: What is the difference between the clear lens of the MPC3PGC and the diffused lens of the MPC3GD?

A: The MPC3PGC features a clear colorless lens that produces a focused point of light. The MPC3GD features a diffused green lens that distributes light more evenly across the viewing area. The choice depends on the desired visual appearance and light distribution requirements in the application.

Q: Why does the MPC3GD have a higher millicandela rating (25mcd versus 10mcd)?

A: The MPC3GD provides greater brightness output due to its diffused lens design and green lens coloration, which enhance light transmission efficiency. This higher brightness is beneficial for visibility in well-lit environments or applications requiring increased indicator prominence.

Q: Is the 13nm wavelength difference between the MPC3PGC (555nm) and MPC3GD (568nm) significant?

A: No. Both wavelengths fall within the green spectrum range. The 13nm difference is not perceptible to human vision and does not affect the functional performance of the indicator in typical applications.

Q: What does the wider viewing angle of the MPC3GD (35° versus 20°) mean for my application?

A: The MPC3GD provides a wider viewing angle, allowing the indicator to be visible from a greater range of viewing positions relative to the panel surface. This is advantageous in applications where operators may view the panel from various angles.

Q: Are there any compliance differences between the MPC3PGC and MPC3GD?

A: The MPC3GD is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The MPC3PGC, being obsolete, may not have current compliance documentation. The MPC3GD is recommended for new designs and applications requiring regulatory compliance verification.

Q: What is the termination style of the MPC3GD?

A: The MPC3GD features PC Pin termination, which is a standard through-hole connection method for panel-mount LED indicators. This termination style is compatible with standard PCB mounting practices.

Q: Can I use the MPC3GD in applications originally designed for the MPC3PGC without any modifications?

A: Yes, provided the application can accommodate the optical differences (diffused lens versus clear lens, higher brightness, and wider viewing angle). The mechanical fit and electrical parameters are fully compatible without circuit or panel modifications.
