Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT94WD18SN is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector type: Receptacle with female sockets
• Position count: 18 positions
• Shell size: 15-18 insert designation
• Mounting configuration: Panel mount with bulkhead front side nut
• Termination method: Crimp contacts
• Fastening: Threaded
• Orientation: Normal (N)
• Shielding: Shielded construction
• Operating temperature: -65°C to 175°C
• Contact finish: Gold plating on mating surfaces
• Shell material: Composite construction
• Ingress protection: Environment resistant rating

The substitute parts identified (CTV07RW-15-18B, CTV07RW-15-18JN, CTV07RW-15-18JN-LC) are manufactured by Amphenol Aerospace Operations under the MIL-DTL-38999 Series III qualification. These parts maintain functional equivalence through identical position count, shell size, mounting methodology, and environmental specifications. Amphenol Aerospace Operations Tri-Start™ TV series connectors are qualified to the same military standard as the original TE Connectivity Deutsch ACT series, ensuring interchangeability in applications requiring MIL-DTL-38999 Series III compliance.

Parameter Comparison

Engineering Selection Recommendations

CTV07RW-15-18JN is the primary substitute for direct replacement of the ACT94WD18SN. This part maintains complete functional equivalence with identical connector type (receptacle with female sockets), position count (18), shell size (15-18), mounting configuration, and environmental specifications. The CTV07RW-15-18JN is manufactured by Amphenol Aerospace Operations and holds active product status, ensuring ongoing availability and supply chain continuity. Both parts are qualified to MIL-DTL-38999 Series III and share identical operating temperature ranges (-65°C to 175°C), contact material (copper alloy), and insert material (thermoplastic). The contact finish specification (gold plating) and shell finish (olive drab cadmium) are identical, supporting direct electrical and mechanical interchangeability.

CTV07RW-15-18B and CTV07RW-15-18JN-LC are receptacle housing alternatives suitable for applications where contacts are supplied separately or managed through independent procurement channels. These parts provide identical mechanical mounting and environmental protection but exclude integrated female socket contacts. Selection of housing-only variants requires confirmation that contact procurement and assembly processes are established within the system design.

All three Amphenol alternatives maintain RoHS non-compliant status consistent with the original part, ensuring regulatory alignment for aerospace and military applications. Moisture sensitivity level (MSL 1 - Unlimited) is preserved across all substitutes, supporting identical storage and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can CTV07RW-15-18B be used as a direct replacement for ACT94WD18SN?

A: CTV07RW-15-18B is a receptacle housing without integrated female socket contacts. Direct replacement requires that female socket contacts are procured and assembled separately. If the application requires a complete pre-assembled receptacle with female sockets, CTV07RW-15-18JN is the appropriate substitute.

Q: What is the difference between CTV07RW-15-18JN and CTV07RW-15-18JN-LC?

A: CTV07RW-15-18JN is a complete receptacle assembly with female sockets and integrated contacts. CTV07RW-15-18JN-LC is a receptacle housing without contacts. Both share identical mechanical mounting, shell size, and environmental specifications. Selection depends on whether contacts are included in the procurement or managed separately.

Q: Are all substitute parts qualified to the same military standard as ACT94WD18SN?

A: Yes. All three substitute parts (CTV07RW-15-18B, CTV07RW-15-18JN, CTV07RW-15-18JN-LC) are qualified to MIL-DTL-38999 Series III, the same standard as the original ACT94WD18SN.

Q: Does the contact finish thickness differ between the original and substitute parts?

A: The ACT94WD18SN specifies gold contact finish thickness of 50.0µin (1.27µm). The CTV07RW-15-18JN specifies 100.0µin (2.54µm) gold plating thickness. Both thicknesses meet MIL-DTL-38999 Series III requirements. The increased thickness in the substitute part provides additional corrosion resistance and contact durability.

Q: Are there any RoHS compliance differences between the original and substitute parts?

A: No. Both the ACT94WD18SN and all substitute parts (CTV07RW-15-18B, CTV07RW-15-18JN, CTV07RW-15-18JN-LC) are RoHS non-compliant, maintaining identical regulatory status for aerospace and military applications.

Q: What is the current inventory status of substitute parts?

A: CTV07RW-15-18B has 974 pieces in stock, CTV07RW-15-18JN has 982 pieces in stock, and CTV07RW-15-18JN-LC has 1111 pieces in stock. All substitute parts maintain active product status with established supply chains.

Q: Can the operating temperature range be exceeded in specific applications?

A: Both the original ACT94WD18SN and all substitute parts are rated for -65°C to 175°C operating temperature. This specification is fixed and cannot be exceeded without component redesign or alternative part selection.

Q: Are the shell materials and finishes identical across all parts?

A: All parts use composite shell material. The ACT94WD18SN and CTV07RW-15-18JN specify olive drab cadmium finish. CTV07RW-15-18B and CTV07RW-15-18JN-LC specify cadmium finish without the olive drab color specification. Both finishes provide equivalent corrosion protection and environmental resistance.
