ACT94MD18SA Equivalent & Substitute Parts

Part Overview

The ACT94MD18SA is an 18-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors, designed for aerospace and military applications. This connector features female sockets with crimp termination, panel mount configuration, and operates across an extended temperature range of -65°C to 200°C. The part is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain functional compatibility within MIL-DTL-38999 Series III specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT94MD18SA is determined by strict alignment of the following parameters: connector type (receptacle housing for female sockets), position count (18), shell size classification (15-18), mounting configuration (panel mount with bulkhead front side nut), termination method (crimp), fastening mechanism (threaded), orientation (A), and shielding requirement (shielded). All substitute parts must operate within the MIL-DTL-38999 Series III standard and maintain compatibility with the specified mechanical and electrical interfaces.

The substitute parts identified—CTV07RW-15-18BA, CTV07RW-15-18JA-LC, and CTV07RW-15-18SA-LC—are receptacle housings manufactured by Amphenol Aerospace Operations under the Tri-Start™ TV series. These components satisfy the core substitution criteria of 18-position configuration, shell size 15-18, panel mount bulkhead installation, threaded fastening, orientation A, and shielded construction. All substitute parts are classified as receptacle housings with contacts not included, requiring separate procurement of crimp contacts compatible with contact size 20.

Parameter Comparison

Engineering Selection Recommendations

The ACT94MD18SA is discontinued, making the active substitute parts from Amphenol Aerospace Operations the appropriate alternatives for ongoing procurement. All three substitute options—CTV07RW-15-18BA, CTV07RW-15-18JA-LC, and CTV07RW-15-18SA-LC—maintain active product status and are available in inventory quantities exceeding 750 units.

A critical distinction exists between the main part and substitute parts: the ACT94MD18SA is supplied as a complete receptacle with integrated female sockets and crimp termination, while the Amphenol substitutes are receptacle housings supplied without contacts. Integration of the Amphenol housings requires separate procurement and installation of crimp contacts rated for contact size 20.

Operating temperature represents a secondary consideration. The ACT94MD18SA operates to 200°C, while all Amphenol substitutes operate to 175°C. Applications requiring operation above 175°C cannot use the substitute parts. For applications within the -65°C to 175°C range, the substitutes provide full functional equivalence.

All parts comply with MIL-DTL-38999 Series III specifications and maintain identical mechanical interfaces: 18-position configuration, shell size 15-18, panel mount bulkhead installation, threaded fastening, and shielded construction. All parts carry RoHS non-compliant status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can CTV07RW-15-18BA, CTV07RW-15-18JA-LC, or CTV07RW-15-18SA-LC directly replace ACT94MD18SA in existing assemblies?

A: Direct mechanical and electrical replacement is possible for applications operating within -65°C to 175°C. The substitute parts are receptacle housings without integrated contacts, requiring separate procurement of crimp contacts. The ACT94MD18SA includes pre-installed female sockets. Integration of substitute parts requires contact installation using appropriate crimp tooling for contact size 20.

Q: What is the difference between the three Amphenol substitute part numbers?

A: CTV07RW-15-18BA, CTV07RW-15-18JA-LC, and CTV07RW-15-18SA-LC are functionally equivalent receptacle housings within the Tri-Start™ TV series. All three share identical electrical and mechanical specifications: 18 positions, shell size 15-18, panel mount bulkhead configuration, threaded fastening, and shielded construction. Differences in part number suffixes reflect manufacturing or finish variations not specified in the provided parameters. All three are active products with available inventory.

Q: Why does the ACT94MD18SA operate to 200°C while the substitutes operate to 175°C?

A: Operating temperature is a specified parameter determined by component design and materials. The ACT94MD18SA is rated for -65°C to 200°C operation, while the Amphenol Tri-Start™ TV series substitutes are rated for -65°C to 175°C. Applications requiring sustained operation above 175°C cannot use the substitute parts.

Q: Are contacts included with the Amphenol substitute parts?

A: No. The Amphenol substitute parts are receptacle housings supplied without contacts. Crimp contacts rated for contact size 20 must be procured separately and installed using appropriate crimp termination equipment.

Q: Do all parts comply with the same military specifications?

A: Yes. The ACT94MD18SA and all three substitute parts conform to MIL-DTL-38999 Series III specifications. The main part is designated ACT series, while substitutes are designated Tri-Start™ TV series, but both series operate within the same military standard.

Q: What is the inventory status of substitute parts?

A: CTV07RW-15-18BA has 1035 units in stock, CTV07RW-15-18JA-LC has 751 units in stock, and CTV07RW-15-18SA-LC has 827 units in stock. All three are classified as active products.
