Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT94MD18PN is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• MIL-DTL-38999 Series III compliance
• 18-position configuration
• Shell size 15-18 (MIL Size D equivalent)
• Receptacle connector type with male pins
• Panel mount with bulkhead front-side nut fastening
• Threaded fastening mechanism
• Crimp termination
• Shielded construction
• Composite shell material
• Thermoplastic insert material
• Normal (N) orientation
• Gold contact finish for mating surfaces
• Copper alloy contact material
• Environment resistant ingress protection
• Operating temperature range compatibility

Substitute Candidates:

The Amphenol Aerospace Operations CTV07RW series connectors satisfy the critical matching parameters. Two specific part numbers provide direct substitution:

1. CTV07RW-15-18HN - Complete receptacle assembly with male pins and crimp termination
2. CTV07RW-15-18A and CTV07RW-15-18HN-LC - Receptacle housing assemblies (contacts not included)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CTV07RW-15-18HN

The CTV07RW-15-18HN is the direct functional equivalent to the ACT94MD18PN. This part maintains all critical electrical and mechanical parameters including 18-position configuration, MIL-DTL-38999 Series III compliance, panel-mount bulkhead installation, crimp termination, and shielded composite construction. The CTV07RW-15-18HN is currently active in production with 681 units in stock, providing immediate availability. The operating temperature range of -65°C to 175°C covers the majority of aerospace and military applications, with the exception of applications requiring the full -65°C to 200°C range of the original part.

Secondary Substitutes: CTV07RW-15-18A and CTV07RW-15-18HN-LC

These housing-only variants are suitable for applications where contacts are sourced separately or where existing contact inventory is available. Both parts maintain mechanical compatibility and MIL-DTL-38999 Series III compliance. These options are appropriate when contact specifications differ from the original assembly or when custom contact configurations are required.

Compliance Considerations

All substitute parts maintain RoHS non-compliant status consistent with the original part, appropriate for aerospace and military applications where RoHS exemptions apply. MSL ratings remain at Level 1 (Unlimited) across all options, indicating no moisture sensitivity constraints for storage or handling.

Frequently Asked Questions (FAQ)

Q: Can CTV07RW-15-18HN directly replace ACT94MD18PN in existing assemblies?

A: Yes. The CTV07RW-15-18HN maintains identical mechanical interfaces, electrical specifications, and MIL-DTL-38999 Series III compliance. Panel-mount bulkhead installation, threaded fastening, and crimp termination are identical. The connector will function as a direct substitute in existing panel cutouts and wiring harnesses.

Q: What is the difference between CTV07RW-15-18HN and CTV07RW-15-18A?

A: CTV07RW-15-18HN is a complete receptacle assembly with male pins and crimp termination included. CTV07RW-15-18A is a receptacle housing only, with contacts not included. Selection depends on whether contacts are sourced separately or as part of the complete assembly.

Q: Does the operating temperature difference affect substitution?

A: The ACT94MD18PN operates to 200°C while substitute parts operate to 175°C. Substitution is appropriate for applications operating within the -65°C to 175°C range. Applications requiring operation above 175°C require evaluation of alternative solutions.

Q: Are the shell finishes compatible?

A: The ACT94MD18PN features nickel shell finish, while CTV07RW-15-18HN features olive drab cadmium finish. Both finishes provide corrosion resistance and environmental protection. The finish difference does not affect electrical performance or mechanical compatibility.

Q: What is the contact finish thickness difference?

A: The ACT94MD18PN specifies 50.0µin (1.27µm) gold contact finish thickness, while CTV07RW-15-18HN specifies 100.0µin (2.54µm). The thicker gold plating on the substitute part provides enhanced wear resistance and contact durability without affecting electrical compatibility.

Q: Are these parts suitable for aviation and marine applications?

A: Yes. The CTV07RW series is specified for aviation, marine, and military applications. All substitute parts maintain MIL-DTL-38999 Series III compliance and environment-resistant ingress protection appropriate for these environments.

Q: What is the current rating for substitute parts?

A: The CTV07RW-15-18HN current rating is not specified in available documentation. The original ACT94MD18PN is rated at 7.5A. For applications with specific current requirements, contact the manufacturer for detailed electrical specifications.

Q: Can CTV07RW-15-18HN-LC be used with existing contact inventory?

A: Yes, if existing contacts are compatible with MIL-DTL-38999 Series III specifications and the 15-18 shell size. The housing-only configuration allows integration with separately sourced contacts. Verify contact specifications match the connector requirements before assembly.
