MPC3GTW12.0 LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The MPC3GTW12.0 is a green LED panel indicator manufactured by Bivar Inc., designed for applications requiring visual status indication. This component features a clear lens with a 20° viewing angle, 2.1V forward voltage, and 30mA maximum current rating. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility while accommodating mechanical and optical variations inherent to the product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPC3GTW12.0 is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Forward voltage (Vf): 2.1V
• Maximum current (If): 30mA
• Lamp color: Green
• Lens size: 3mm, T-1
• Panel cutout shape and dimensions: Round, 0.24" (6.10mm)
• Termination style: Wire leads with 12" (304.80mm) length
• Wavelength peak: 568nm

Allowable Variations:

• Lens transparency: Clear or diffused formulations are interchangeable within the same electrical and mechanical specifications
• Viewing angle: Range from 20° to 35° accommodates different optical designs
• Millicandela rating: Brightness variations between 25mcd and 40mcd are acceptable for equivalent function

The MPC3GDW12.0 qualifies as a direct substitute based on matching all mandatory parameters while introducing controlled variations in lens transparency (diffused vs. clear) and optical characteristics (35° vs. 20° viewing angle).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production Transitions:

The MPC3GDW12.0 is the recommended substitute for the obsolete MPC3GTW12.0. Both components share identical electrical specifications (2.1V, 30mA), mechanical compatibility (3mm T-1 lens, 0.24" panel cutout, 12" wire leads), and regulatory compliance (EAR99, HTSUS 8541.41.0000, MSL 1).

Optical Characteristic Considerations:

The MPC3GDW12.0 introduces two optical variations:

• Diffused lens transparency replaces the clear lens, resulting in a softer, more dispersed light output
• Viewing angle expands from 20° to 35°, providing wider visibility range
• Millicandela rating decreases from 40mcd to 25mcd, reflecting the diffused lens design

These variations maintain functional equivalence for panel indicator applications while offering improved visibility distribution in certain mounting orientations.

Product Status Advantage:

The MPC3GDW12.0 carries active product status with current inventory availability (1708 pcs), ensuring long-term supply chain reliability compared to the obsolete MPC3GTW12.0 (1006 pcs remaining stock).

Compliance Status:

The MPC3GDW12.0 includes ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the MPC3GDW12.0 replace the MPC3GTW12.0 in existing circuit designs without modification?

A: Yes. Both components operate at identical voltage (2.1V) and current (30mA) specifications. No circuit modifications are required. The driver circuit, current-limiting resistor calculations, and power supply requirements remain unchanged.

Q: What is the functional difference between the clear lens (MPC3GTW12.0) and diffused lens (MPC3GDW12.0)?

A: The clear lens provides a more concentrated, focused light output with a 20° viewing angle and 40mcd brightness. The diffused lens scatters light over a wider 35° viewing angle with 25mcd brightness. Both are suitable for panel indicator applications; selection depends on desired visibility characteristics and mounting position.

Q: Will the MPC3GDW12.0 fit the same panel cutout as the MPC3GTW12.0?

A: Yes. Both components feature identical 3mm T-1 lens size and 0.24" (6.10mm) round panel cutout dimensions. Mechanical installation is identical.

Q: Are the wire lead lengths the same?

A: Yes. Both components feature 12" (304.80mm) wire leads, ensuring identical assembly and routing compatibility.

Q: What is the significance of the obsolete status for MPC3GTW12.0?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory is limited (1006 pcs). The MPC3GDW12.0 is the active equivalent, ensuring continued availability for future production runs and design updates.

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

A: No. Both components share identical ECCN (EAR99), HTSUS code (8541.41.0000), and MSL rating (1 - Unlimited). The MPC3GDW12.0 additionally carries ROHS3 compliance and REACH unaffected status, meeting current regulatory standards.

Q: Can brightness differences between 40mcd and 25mcd affect circuit operation?

A: No. Brightness (millicandela rating) is a luminous intensity characteristic determined by the lens design and LED die. It does not affect electrical circuit operation, voltage drop, or current draw. Both components maintain identical 2.1V/30mA electrical specifications.

Q: Is the MPC3GDW12.0 suitable for applications requiring maximum brightness?

A: The MPC3GDW12.0 provides 25mcd brightness compared to the original 40mcd. For applications with strict brightness requirements, this variation should be evaluated against specific visibility thresholds. However, for standard panel indicator applications, 25mcd is typically sufficient.
