Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0382500406 is determined by the following critical parameters:

Core Compatibility Requirements:

• Terminal block type: Barrier block
• Number of circuits: 6
• Pitch spacing: 0.438" (11.12mm)
• Number of rows: 1
• Barrier construction: 2 Wall (Dual)
• Mounting type: Chassis, Panel
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The Curtis Industries 431000-06-0 meets all core compatibility requirements. While this substitute exhibits higher electrical ratings (20A current, 600V voltage) and different insulation material (polypropylene versus phenolic), these represent performance enhancements rather than incompatibilities. The substitute maintains identical circuit count, pitch, barrier configuration, and mounting characteristics, enabling direct functional replacement in applications requiring this connector form factor.

Parameter Comparison

Engineering Selection Recommendations

The Curtis Industries 431000-06-0 is the designated equivalent for the obsolete Molex 0382500406. Selection of this substitute is supported by:

Product Status: The Molex component is obsolete, while the Curtis Industries alternative maintains active product status with confirmed inventory availability (753 pcs in stock).

Regulatory Compliance: Both components achieve UL94 V-0 flammability rating and ROHS3 compliance, meeting current environmental and safety standards.

Electrical Performance: The Curtis Industries substitute provides enhanced electrical specifications (20A versus 15A current rating; 600V versus 300V voltage rating), ensuring compatibility with applications designed for the original component while supporting higher-demand use cases.

Physical Compatibility: Identical pitch spacing (0.438"), circuit count (6), barrier configuration (dual-wall), and mounting options (chassis/panel) ensure direct mechanical and electrical interchangeability.

For applications where the original Molex 0382500406 is specified, the Curtis Industries 431000-06-0 provides a compliant, actively supported replacement with superior electrical ratings and regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 431000-06-0 be used as a direct replacement for the Molex 0382500406?

A: Yes. Both components share identical circuit count (6), pitch spacing (0.438"), barrier type (dual-wall), and mounting configuration (chassis/panel). The Curtis Industries part maintains all functional and mechanical compatibility requirements.

Q: What are the key differences between these two components?

A: The Curtis Industries substitute provides higher electrical ratings (20A versus 15A; 600V versus 300V), uses polypropylene insulation instead of phenolic, and maintains active product status. Both achieve UL94 V-0 flammability rating and ROHS3 compliance.

Q: Does the higher voltage and current rating of the substitute create any compatibility issues?

A: No. Higher electrical ratings represent performance enhancements. Applications designed for the original 15A/300V specifications operate safely within the substitute's 20A/600V capability.

Q: Are there packaging differences between these components?

A: The Molex component is listed with unspecified packaging, while the Curtis Industries substitute is supplied in bulk packaging. Both are available in new original condition.

Q: What wire gauge compatibility should be considered?

A: The Molex component accepts 14-24 AWG wire, while the Curtis Industries substitute accepts 12-22 AWG. Applications using 14-22 AWG wire are compatible with both components. Applications requiring 12 AWG or 24 AWG wire must use the Curtis Industries substitute or original Molex component, respectively.

Q: Are both components RoHS compliant?

A: Yes. Both the Molex 0382500406 and Curtis Industries 431000-06-0 are ROHS3 compliant.
