Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0382500413 is determined by the following critical parameters:

• Circuit Configuration: 13 circuits with 0.438" (11.12mm) pitch spacing (mechanical and electrical compatibility requirement)
• Barrier Block Type: Dual-wall (2 Wall) barrier construction (safety and isolation standard)
• Termination Method: Screw-based top termination with closed bottom termination (installation compatibility)
• Mounting Interface: Chassis and panel mounting capability (form factor requirement)
• Electrical Performance: Minimum 15A current rating and 300V voltage rating (functional requirement floor)
• Wire Gauge Compatibility: Overlap within 12-24 AWG range (terminal acceptance requirement)
• Flammability Compliance: UL94 V-0 rating (safety standard requirement)
• RoHS Compliance: ROHS3 Compliant status (regulatory requirement)

The Curtis Industries 431000-13-0 meets all critical substitution criteria with enhanced electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The Curtis Industries 431000-13-0 is the qualified substitute for the obsolete Molex 0382500413. Selection is based on the following engineering factors:

Mechanical Compatibility: Both components share identical circuit count (13), pitch spacing (0.438"), row configuration (1), and mounting interface (chassis/panel). Physical installation compatibility is confirmed.

Electrical Performance: The Curtis Industries substitute provides enhanced electrical ratings (20A vs. 15A current; 600V vs. 300V voltage), ensuring safe operation in applications originally designed for the Molex component. The wire gauge overlap (14-22 AWG) accommodates standard installation practices.

Regulatory Compliance: Both components maintain UL94 V-0 flammability certification and ROHS3 compliance, meeting current regulatory requirements for electronic component deployment.

Product Availability: The Curtis Industries 431000-13-0 maintains active product status with current manufacturing support, ensuring long-term availability for replacement and new installations, whereas the Molex component is obsolete.

Termination Compatibility: Both components utilize screw-based top termination with closed bottom termination, maintaining installation methodology consistency.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 431000-13-0 be used as a direct replacement for the Molex 0382500413?

A: Yes. Both components share identical circuit configuration (13 circuits), pitch spacing (0.438"), barrier type (dual-wall), and mounting interface. The Curtis Industries substitute meets or exceeds all electrical and mechanical parameters of the original component.

Q: What is the wire gauge compatibility between these two components?

A: The Molex 0382500413 accepts 14-24 AWG wire, while the Curtis Industries 431000-13-0 accepts 12-22 AWG wire. The overlap range of 14-22 AWG is compatible with both components. Wire gauges 23-24 AWG are compatible only with the original Molex component; wire gauge 12 AWG is compatible only with the Curtis Industries substitute.

Q: Are there differences in operating temperature ratings?

A: Yes. The Molex 0382500413 operates to 150°C, while the Curtis Industries 431000-13-0 operates to 105°C. Applications requiring operation above 105°C must use the original Molex component or identify alternative solutions.

Q: What is the difference in insulation material?

A: The Molex 0382500413 uses phenolic (phenol formaldehyde) insulation, while the Curtis Industries 431000-13-0 uses polypropylene (PP) insulation. Both materials meet UL94 V-0 flammability requirements. Material selection should be verified against specific application chemical exposure requirements.

Q: Why is the Molex component listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The Curtis Industries 431000-13-0 maintains active product status with current manufacturing availability.

Q: Are both components RoHS compliant?

A: Yes. Both the Molex 0382500413 and Curtis Industries 431000-13-0 are ROHS3 compliant, meeting current environmental and regulatory standards for electronic component manufacturing.
