MPC3PGT LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPC3PGT is a panel-mounted LED indicator manufactured by Bivar Inc., featuring a green clear lens with 10mcd brightness at 555nm wavelength. This component is classified as Obsolete product status, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The MPC3 series maintains consistent mechanical and electrical interfaces across active variants, enabling direct functional substitution where parameter tolerances permit.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MPC3PGT requires identification of active components within the MPC3 series that maintain mechanical and electrical compatibility. The following criteria establish valid substitution relationships:

Mandatory Compatibility Parameters:

• Lens Size: 3mm, T-1 (physical form factor)
• Panel Cutout Shape: Round (mechanical interface)
• Panel Cutout Dimensions: 0.24" (6.10mm) (mounting hole diameter)
• Lamp Color: Green (functional requirement)
• Current Rating: 30mA maximum (circuit design constraint)

Allowable Variation Parameters:

• Lens Transparency: Clear or Diffused (both acceptable for indicator function)
• Voltage (Vf): 2.1V to 2.2V range (within typical circuit tolerance)
• Millicandela Rating: 10mcd to 25mcd (brightness increase acceptable for indicator applications)
• Wavelength: 555nm to 568nm (green spectrum, visually equivalent)
• Viewing Angle: 20° to 35° (wider angle acceptable for panel indicators)

The MPC3GD substitute part satisfies all mandatory compatibility parameters while remaining within allowable variation ranges for optical and electrical characteristics.

Engineering Selection Recommendations

Primary Substitute: MPC3GD

The MPC3GD is the direct functional equivalent for the obsolete MPC3PGT. Selection rationale is based on the following engineering factors:

Mechanical Compatibility: Both components share identical lens size (3mm, T-1), panel cutout shape (round), and panel cutout dimensions (0.24"/6.10mm). Direct mechanical substitution is confirmed without modification to panel mounting hardware or cutout geometry.

Electrical Compatibility: The MPC3GD operates at 2.1V typical forward voltage compared to 2.2V for the MPC3PGT, representing a 0.1V difference within standard circuit design tolerance. Both components are rated for 30mA maximum current, ensuring compatibility with existing current-limiting resistor calculations and power supply specifications.

Optical Characteristics: The MPC3GD features a diffused lens compared to the clear lens of the MPC3PGT. This change increases the viewing angle from 20° to 35° and increases brightness from 10mcd to 25mcd. For panel indicator applications, diffused lenses provide improved visibility across wider viewing angles and are functionally superior for human-machine interface requirements.

Product Status and Compliance: The MPC3GD is classified as Active product status with confirmed availability (1087 pcs in stock). The substitute meets ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for new designs and production.

Inventory Availability: The MPC3GD is available in Tray packaging with 1087 units in stock, providing immediate procurement capability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the MPC3GD directly replace the MPC3PGT without circuit modification?

A: Yes. The MPC3GD operates at 2.1V typical forward voltage compared to 2.2V for the MPC3PGT. This 0.1V difference is within standard circuit design tolerance and does not require modification to current-limiting resistor values or power supply specifications. Both components are rated for 30mA maximum current.

Q: What is the difference between the clear lens (MPC3PGT) and diffused lens (MPC3GD)?

A: The MPC3PGT features a clear lens with a 20° viewing angle and 10mcd brightness. The MPC3GD features a diffused lens with a 35° viewing angle and 25mcd brightness. The diffused lens scatters light across a wider angle, improving visibility from off-axis viewing positions. For panel indicator applications, the diffused lens is functionally superior and provides enhanced human-machine interface visibility.

Q: Are there any mechanical modifications required to install the MPC3GD in place of the MPC3PGT?

A: No mechanical modifications are required. Both components have identical panel cutout dimensions (0.24"/6.10mm round), lens size (3mm, T-1), and lens style (round with domed top). The MPC3GD installs directly into existing panel cutouts designed for the MPC3PGT.

Q: What is the wavelength difference between the MPC3PGT and MPC3GD?

A: The MPC3PGT has a peak wavelength of 555nm, while the MPC3GD has a peak wavelength of 568nm. Both wavelengths are within the green spectrum and are visually equivalent for human perception. The 13nm difference is not perceptible to the human eye in panel indicator applications.

Q: Does the MPC3GD meet current regulatory compliance requirements?

A: Yes. The MPC3GD is ROHS3 compliant and REACH unaffected. The obsolete MPC3PGT does not have specified compliance status. The MPC3GD is suitable for new designs and production requiring current regulatory compliance.

Q: What is the packaging difference between the MPC3PGT and MPC3GD?

A: The MPC3PGT packaging is specified as "-" (not detailed in available documentation). The MPC3GD is supplied in Tray packaging. Tray packaging is standard for LED components and provides organized component presentation for automated assembly processes.

Q: Is the MPC3GD available for immediate procurement?

A: Yes. The MPC3GD is classified as Active product status with 1087 units in stock. The component is available for immediate procurement without lead time constraints.

Q: Can the MPC3GD be used in applications requiring the exact 555nm wavelength specification?

A: The MPC3GD operates at 568nm peak wavelength compared to 555nm for the MPC3PGT. If the application requires the exact 555nm specification for technical reasons, the wavelength difference must be evaluated against application requirements. For standard panel indicator applications, the 13nm difference is not functionally significant.
