MPC3PGD LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The MPC3PGD 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, indicating it is no longer in active production. The MPC3PGD delivers 5 millicandela output at a peak wavelength of 555nm with a 35° viewing angle, operating at 2.2V forward voltage and 30mA maximum current.

Due to its obsolete status, locating replacement inventory from original sources becomes increasingly difficult. Identifying equivalent substitute parts with compatible electrical and mechanical specifications ensures continued availability for maintenance, repair, and production applications requiring this component category.

Substitute Part Grouping Explanation

Substitution of the MPC3PGD is determined by compatibility across mechanical, electrical, and optical parameters. The following criteria establish whether an alternative part functions as a direct equivalent:

Mechanical Compatibility Requirements:

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

Electrical Compatibility Requirements:

• Maximum current rating must be 30mA
• Forward voltage must operate within the circuit design tolerance

Optical Compatibility Requirements:

• Lamp color must be green
• Lens color must be green
• Lens transparency must be diffused
• Viewing angle must be 35°

Product Family Alignment:

• Part must belong to the MPC3 series

The MPC3GD substitute part satisfies all mechanical requirements, maintains the 30mA current specification, and preserves the optical characteristics of green diffused lens with 35° viewing angle. Variations in forward voltage (2.1V versus 2.2V) and millicandela output (25mcd versus 5mcd) represent performance enhancements within the same product family and application category.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MPC3GD

The MPC3GD is the recommended substitute for the obsolete MPC3PGD based on the following engineering criteria:

Mechanical Compatibility: The MPC3GD maintains identical mechanical specifications, including 3mm T-1 lens form factor, round panel cutout shape, and 0.24" (6.10mm) cutout dimensions. Direct mechanical interchangeability is confirmed for panel-mount applications.

Electrical Compatibility: Both parts operate at 30mA maximum current. The forward voltage difference of 0.1V (2.1V versus 2.2V) falls within typical circuit design tolerances for LED indicator applications and does not require circuit modification.

Optical Compatibility: The MPC3GD preserves the green diffused lens configuration and 35° viewing angle. The wavelength shift from 555nm to 568nm and increased millicandela output from 5mcd to 25mcd represent performance improvements within the green spectrum range, enhancing visibility without altering the optical character of the indicator.

Product Status and Compliance: The MPC3GD holds Active product status with confirmed RoHS3 compliance and REACH unaffected designation. The MPC3PGD is classified as Obsolete, making the MPC3GD the appropriate long-term solution for continued component availability.

Termination Consideration: The MPC3GD features PC Pin termination, whereas the MPC3PGD termination style is not specified. Verify termination compatibility with existing circuit board designs before final selection.

Frequently Asked Questions (FAQ)

Q: Can the MPC3GD directly replace the MPC3PGD in existing panel assemblies?

A: Yes, the MPC3GD provides direct mechanical replacement for the MPC3PGD. Both components share identical lens size (3mm T-1), panel cutout shape (round), and cutout dimensions (0.24" / 6.10mm). Panel mounting hardware and mechanical interfaces are fully compatible.

Q: What is the significance of the forward voltage difference between MPC3PGD (2.2V) and MPC3GD (2.1V)?

A: The 0.1V difference represents a minor variation within typical LED indicator circuit design margins. Most current-limiting resistor designs accommodate this variance without requiring modification. However, circuits with tight voltage tolerance specifications should be evaluated individually.

Q: Why does the MPC3GD have higher millicandela output (25mcd) than the MPC3PGD (5mcd)?

A: The increased brightness of the MPC3GD represents a performance enhancement within the same product family. This improvement provides better visibility in applications requiring higher luminous intensity. The substitute part delivers superior optical performance while maintaining all other specified parameters.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The MPC3GD carries RoHS3 compliance and REACH unaffected status. The MPC3PGD is obsolete and no longer subject to active compliance tracking. The MPC3GD is the compliant choice for new designs and ongoing production.

Q: What is the difference between the termination styles listed for these parts?

A: The MPC3PGD termination style is not specified in available documentation. The MPC3GD features PC Pin termination, which is standard for panel-mount LED indicators. Verify that PC Pin termination is compatible with your circuit board design before proceeding with substitution.

Q: Can the MPC3GD be used in applications where the original MPC3PGD was specified?

A: The MPC3GD is suitable for applications requiring green diffused LED panel indicators with 3mm T-1 form factor, 30mA operation, and 35° viewing angle. The enhanced brightness and improved product status make it the preferred choice for both replacement and new applications. Confirm termination compatibility with your specific circuit design.

Q: What is the wavelength difference between 555nm (MPC3PGD) and 568nm (MPC3GD)?

A: Both wavelengths fall within the green spectrum range. The 13nm difference represents a shift toward the yellow-green portion of the spectrum. This variation is imperceptible to the human eye in typical indicator applications and does not affect functional performance or color perception in standard panel indicator use.

Q: Is the MPC3GD available in the same packaging as the MPC3PGD?

A: The MPC3GD is supplied in Tray packaging. The MPC3PGD packaging format is not specified in available documentation. Confirm packaging requirements for your procurement and assembly processes.
