ACT94MD19PA Equivalent & Substitute Parts

Part Overview

The ACT94MD19PA is a 19-position circular connector receptacle with male pins, manufactured by TE Connectivity Deutsch Connectors. This component is designed for aerospace and military applications requiring panel-mount bulkhead installation with crimp termination. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain compatibility with existing system requirements while meeting MIL-DTL-38999 Series III specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT94MD19PA is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 19
• Shell Size - Insert: 15-19
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Front Side Nut
• Fastening Type: Threaded
• Orientation: A
• Shielding: Shielded
• Series: MIL-DTL-38999 Series III

Compatible Variation Parameters:

• Connector Type: Receptacle housing for male pins (functionally equivalent to receptacle with male pins)
• Termination: Crimp contact type
• Operating Temperature: Substitute must support minimum -65°C to 175°C (subset of original -65°C to 200°C range)
• Contact Finish: Gold or equivalent aerospace-grade finish
• RoHS Status: Non-compliant (consistent with military/aerospace applications)

The CTV07RW-15-19AA from Amphenol Aerospace Operations meets all mandatory parameters and operates within the required temperature envelope for most aerospace and military applications.

Engineering Selection Recommendations

Primary Substitute: CTV07RW-15-19AA

The CTV07RW-15-19AA is the appropriate substitute for the discontinued ACT94MD19PA based on the following engineering criteria:

1. Standard Compliance: Both components conform to MIL-DTL-38999 Series III, ensuring mechanical and electrical interchangeability within the standard's specifications.

2. Mechanical Compatibility: Identical shell size (15-19), mounting configuration (panel mount bulkhead), and fastening method (threaded) ensure direct mechanical substitution in existing panel cutouts and mounting structures.

3. Electrical Compatibility: Both components provide shielded 19-position connectivity with crimp termination, supporting the same signal integrity and current-carrying requirements (7.5A).

4. Availability: The CTV07RW-15-19AA is currently active in production with 826 pieces in stock, addressing the discontinuation of the original part.

5. Regulatory Alignment: Both components maintain identical RoHS non-compliance status and MSL rating, appropriate for aerospace and military applications where exemptions apply.

Temperature Consideration: The substitute operates to 175°C versus the original 200°C maximum. Applications requiring sustained operation above 175°C require engineering evaluation of thermal margins in the specific system design.

Contact Configuration: The CTV07RW-15-19AA is supplied as a receptacle housing without contacts included. Procurement of compatible crimp contacts (contact size 20) is required as a separate line item.

Frequently Asked Questions (FAQ)

Q: Can the CTV07RW-15-19AA directly replace the ACT94MD19PA in existing assemblies?

A: Yes, for applications operating within the -65°C to 175°C temperature range. Both components share identical MIL-DTL-38999 Series III specifications, 19-position configuration, shell size, mounting method, and fastening type. The substitute is mechanically and electrically compatible for panel-mount bulkhead installations.

Q: What is the difference between "Receptacle, Male Pins" and "Receptacle Housing for Male Pins"?

A: The ACT94MD19PA is specified as a complete receptacle assembly with integrated male pins. The CTV07RW-15-19AA is specified as a receptacle housing designed to accept male pins via crimp contacts. Both function identically in the mated connector pair; the housing designation indicates contacts are procured separately.

Q: Are contacts included with the CTV07RW-15-19AA?

A: No. The CTV07RW-15-19AA is supplied as a housing only. Compatible crimp contacts (contact size 20) must be ordered separately and installed into the receptacle housing prior to assembly.

Q: What is the maximum operating temperature difference between these parts?

A: The ACT94MD19PA operates to 200°C, while the CTV07RW-15-19AA operates to 175°C. This 25°C difference represents a reduction in maximum thermal capability. Applications requiring sustained operation above 175°C must evaluate thermal margins within the specific system design.

Q: Are both parts compliant with RoHS regulations?

A: No. Both the ACT94MD19PA and CTV07RW-15-19AA are RoHS non-compliant. This status is appropriate for aerospace and military applications where RoHS exemptions are granted under applicable regulations.

Q: What is the shell size designation "15-19" and "D"?

A: Shell size 15-19 refers to the MIL-DTL-38999 insert size range accommodating 15 to 19 contact positions. Shell size "D" is the corresponding MIL designation for this insert range. Both parts use identical shell sizing.

Q: Can these connectors be used interchangeably with other MIL-DTL-38999 Series III manufacturers?

A: Yes, within the constraints of matching all critical parameters (position count, shell size, mounting type, orientation, and fastening method). MIL-DTL-38999 Series III standardization ensures mechanical and electrical interchangeability across qualified manufacturers when these parameters align.

Q: What contact finish is used on the CTV07RW-15-19AA?

A: The substitute part specification does not explicitly state the contact finish material. The original ACT94MD19PA uses gold-plated contacts (50.0µin thickness). Contact finish specifications for the CTV07RW-15-19AA must be confirmed through the manufacturer's detailed technical documentation or contact specification sheets prior to procurement.
