ACT94MD18PA Equivalent & Substitute Parts

Part Overview

The ACT94MD18PA is an 18-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors, designed for aerospace and military applications. This component features male pins with crimp termination, panel mount configuration, and operates across a temperature range of -65°C to 200°C. 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 ACT94MD18PA is determined by strict alignment of the following critical parameters:

Position and Connector Architecture: The substitute must accommodate 18 positions with shell size 15-18 and MIL size D, maintaining receptacle configuration for male pins.

Mechanical Interface: Panel mount configuration with bulkhead front-side nut fastening and threaded fastening type must be preserved to ensure physical compatibility with existing panel cutouts and mounting hardware.

Electrical and Environmental Specifications: Shielded construction, crimp termination, and orientation A are mandatory for signal integrity and installation consistency.

Operational Envelope: The substitute must support the aerospace and military application domain with MIL-DTL-38999 Series III compliance.

The CTV07RW-15-18AA from Amphenol Aerospace Operations satisfies these core substitution criteria through identical position count, shell sizing, mounting configuration, and series compliance.

Parameter Comparison

Engineering Selection Recommendations

Availability and Product Status: The ACT94MD18PA is discontinued at DiGi Electronics, while the CTV07RW-15-18AA maintains active product status with 674 units in stock. For new procurement or replenishment, the CTV07RW-15-18AA provides assured supply continuity.

Compliance Alignment: Both components are RoHS non-compliant and carry identical ECCN (EAR99) and HTSUS classifications, maintaining regulatory consistency for aerospace and military applications.

Operational Temperature Consideration: The ACT94MD18PA operates to 200°C, while the CTV07RW-15-18AA operates to 175°C. Applications requiring sustained operation above 175°C require verification that the substitute meets thermal requirements.

Mechanical and Electrical Compatibility: The CTV07RW-15-18AA satisfies all critical mechanical interface parameters (18 positions, shell size 15-18, panel mount, bulkhead configuration, threaded fastening, orientation A) and electrical specifications (shielded, crimp termination, MIL-DTL-38999 Series III compliance).

Contact Finish Specification: The ACT94MD18PA specifies gold mating contact finish; the CTV07RW-15-18AA does not provide explicit contact finish specification in available documentation. System designers must confirm contact finish compatibility with mating connector specifications.

Shell Material and Finish: The ACT94MD18PA features nickel-finished composite shell; the CTV07RW-15-18AA features cadmium-finished composite shell. Environmental exposure requirements and corrosion resistance specifications must be evaluated for specific applications.

Frequently Asked Questions (FAQ)

Q: Can the CTV07RW-15-18AA directly replace the ACT94MD18PA in existing assemblies?

A: The CTV07RW-15-18AA provides mechanical and electrical compatibility for the 18-position, MIL-DTL-38999 Series III panel mount configuration. However, applications operating above 175°C require thermal verification, and contact finish specifications must be confirmed against mating connector requirements.

Q: What is the significance of the "Receptacle Housing" designation for the CTV07RW-15-18AA?

A: The CTV07RW-15-18AA is specified as a receptacle housing for male pins, indicating that contacts are not included with the housing. The ACT94MD18PA is specified as a complete receptacle with male pins. Procurement must account for separate contact acquisition if not already in inventory.

Q: Are there differences in shell material between these connectors?

A: Both connectors use composite shell material. The ACT94MD18PA features nickel finish, while the CTV07RW-15-18AA features cadmium finish. Finish selection affects corrosion resistance and environmental performance in specific exposure conditions.

Q: What is the impact of the 25°C temperature difference in operating range?

A: The ACT94MD18PA operates to 200°C; the CTV07RW-15-18AA operates to 175°C. Applications requiring sustained operation above 175°C must retain the original ACT94MD18PA or identify alternative solutions. Applications operating within the 175°C limit are unaffected.

Q: How do the MIL-DTL-38999 Series III designations differ between ACT and Tri-Start™ TV product lines?

A: Both connectors comply with MIL-DTL-38999 Series III standard. The ACT designation identifies the TE Connectivity Deutsch product line; Tri-Start™ TV identifies the Amphenol Aerospace product line. Both meet the same military specification for 18-position circular connectors.

Q: What packaging considerations apply to the CTV07RW-15-18AA?

A: The CTV07RW-15-18AA is supplied in bulk packaging, whereas the ACT94MD18PA packaging is not specified. Bulk packaging may require internal inventory management procedures for component tracking and handling.

Q: Are both connectors suitable for aerospace and military applications?

A: Both connectors are designated for aerospace and military applications and carry identical ECCN (EAR99) and HTSUS classifications, confirming regulatory suitability for these application domains.
