ACT94MD19SN Equivalent & Substitute Parts

Part Overview

The ACT94MD19SN is a 19-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors, designed for panel mount applications with female sockets and crimp termination. This connector conforms to MIL-DTL-38999 Series III specifications and is rated for aerospace and military applications across an operating temperature range of -65°C to 200°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active product lines that maintain compatibility with existing system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT94MD19SN is determined by strict adherence to the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Receptacle with female sockets
• Position count: 19 positions
• Shell size: 15-19 insert size
• Mounting configuration: Panel mount with bulkhead front side nut
• Termination method: Crimp
• Fastening: Threaded
• Orientation: Normal (N)
• Shielding: Shielded
• Contact finish: Gold plating on mating surfaces
• Shell material: Composite construction
• Series compliance: MIL-DTL-38999 Series III

The substitute parts identified (CTV07RW series from Amphenol Aerospace Operations) maintain these core parameters while offering active product status. Two distinct connector types are present within the substitute group: complete receptacle assemblies with integrated female sockets (CTV07RW-15-19JN) and receptacle housings without contacts (CTV07RW-15-19B and CTV07RW-15-19JN-LC), which require separate contact procurement.

Parameter Comparison

Engineering Selection Recommendations

CTV07RW-15-19JN (Primary Substitute)

The CTV07RW-15-19JN from Amphenol Aerospace Operations is the direct functional equivalent to the ACT94MD19SN. This connector maintains all critical parameters including 19-position configuration, composite shell construction, gold-plated mating contacts, crimp termination, and MIL-DTL-38999 Series III compliance. The part is currently in active production status with 888 units in stock. The primary operational difference is the maximum operating temperature specification of -65°C to 175°C, which is 25°C lower than the original part. This substitute is appropriate for applications where the upper temperature limit does not exceed 175°C. Contact finish thickness on the CTV07RW-15-19JN is 100.0µin (2.54µm), compared to 50.0µin (1.27µm) on the original part, providing enhanced contact durability.

CTV07RW-15-19B and CTV07RW-15-19JN-LC (Housing-Only Alternatives)

The CTV07RW-15-19B and CTV07RW-15-19JN-LC are receptacle housings without integrated contacts. These parts are suitable only for applications where contacts are procured separately or where existing contacts from the original ACT94MD19SN assembly can be transferred. Both housing options maintain the same mechanical and environmental specifications as the complete CTV07RW-15-19JN assembly. These alternatives are appropriate for repair, rework, or custom assembly scenarios where contact replacement is required independently of the housing.

Compliance and Availability

All substitute parts maintain MIL-DTL-38999 Series III compliance and RoHS non-compliant status consistent with the original part. All alternatives carry MSL Rating 1 (Unlimited) moisture sensitivity classification. The Amphenol Aerospace Operations CTV07RW series parts are actively manufactured and stocked, ensuring long-term availability compared to the discontinued ACT94MD19SN.

Frequently Asked Questions (FAQ)

Q: Can the CTV07RW-15-19JN be used as a direct replacement for the ACT94MD19SN?

A: The CTV07RW-15-19JN is functionally equivalent for all mechanical and electrical parameters except maximum operating temperature. The substitute operates to 175°C versus 200°C for the original part. Direct substitution is valid for applications where the upper temperature limit does not exceed 175°C.

Q: What is the difference between CTV07RW-15-19JN and the housing-only variants?

A: The CTV07RW-15-19JN is a complete receptacle assembly with integrated female sockets and gold-plated contacts. The CTV07RW-15-19B and CTV07RW-15-19JN-LC are housings only and do not include contacts. Housing-only variants require separate contact procurement or transfer of existing contacts from another assembly.

Q: Are the substitute parts compatible with existing mating plugs designed for the ACT94MD19SN?

A: Yes. All substitute parts maintain the same shell size (15-19), position count (19), orientation (Normal), and MIL-DTL-38999 Series III compliance as the original part. Mating compatibility is preserved across all alternatives.

Q: What is the significance of the contact finish thickness difference?

A: The CTV07RW-15-19JN provides 100.0µin (2.54µm) gold plating thickness compared to 50.0µin (1.27µm) on the ACT94MD19SN. The increased thickness on the substitute part provides enhanced contact durability and wear resistance, particularly beneficial for high-cycle mating applications.

Q: Can I use the housing-only parts if I have spare contacts from the original ACT94MD19SN?

A: Contact compatibility between the ACT94MD19SN and CTV07RW series housings is determined by contact size and crimp specifications. The CTV07RW series housings are specified for contact size 20. Verification of contact specifications is required before transfer of contacts between assemblies.

Q: What is the current availability status of these substitute parts?

A: The CTV07RW-15-19JN is in active production with 888 units in stock. The CTV07RW-15-19B and CTV07RW-15-19JN-LC are also active with 1106 and 978 units in stock respectively. All alternatives offer superior long-term availability compared to the discontinued ACT94MD19SN.

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

A: Both the original ACT94MD19SN and all CTV07RW substitutes are RoHS non-compliant and carry MSL Rating 1 (Unlimited). Environmental resistance specifications are identical across all parts. All parts are suitable for aerospace and military applications.
