Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96MD18SN-3025 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector type: Plug with female sockets
• Number of positions: 18
• Shell size (MIL-DTL-38999): D-size (15-18 insert)
• Termination method: Crimp
• Fastening type: Threaded
• Mounting configuration: Free Hanging (In-Line)
• Shielding: Shielded
• Ingress protection: Environment Resistant
• Contact finish: Gold plating on mating surfaces
• Current rating: 7.5A
• Operating temperature range: -65°C minimum to 200°C maximum
• Regulatory compliance: EAR99 classification

Substitute parts must satisfy all primary criteria to ensure mechanical fit, electrical performance, and system compatibility. Parts listed below meet these requirements across different manufacturers within the MIL-DTL-38999 Series III specification family.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - D38999/26WD18SN (Souriau-Sunbank by Eaton): This part is the preferred substitute due to highest inventory availability (21700 pieces), active product status, and full compliance with all critical parameters. The part maintains MIL-DTL-38999 Series III specification compliance and carries EAR99 classification matching the original part. RoHS non-compliant status aligns with the original specification for aerospace and military applications.

Secondary Substitute - D38999/26FD18SN (Glenair): This connector meets all functional and electrical requirements with 741 pieces in stock and active product status. REACH Unaffected designation provides additional regulatory clarity. EAR99 classification and MSL 1 rating confirm compatibility with original application requirements.

Tertiary Substitute - D38999/26WD18SNLC (Amphenol Aerospace Operations): This part functions as a plug housing assembly for female sockets with 683 pieces available. Operating temperature range extends to -65°C ~ 175°C, which is 25°C lower than the original part's maximum. This part is suitable for applications not requiring the full 200°C upper temperature limit. Active product status and MIL-DTL-38999 Series III compliance confirm aerospace qualification.

Alternative Substitute - CTVS06RF-15-18S (Amphenol Aerospace Operations): This connector provides functional equivalence with 986 pieces in stock and active product status. All critical mechanical and electrical parameters align with the original specification. Series designation not specified in available data.

Frequently Asked Questions (FAQ)

Q: Can D38999/26WD18SN directly replace ACT96MD18SN-3025 in existing assemblies?

A: Yes. Both connectors are 18-position, D-size, MIL-DTL-38999 Series III plugs with female sockets, crimp termination, threaded fastening, and gold-plated contacts. Mechanical fit and electrical performance are equivalent.

Q: What is the difference between D38999/26WD18SN and D38999/26FD18SN?

A: Both are 18-position D-size plugs with female sockets meeting identical functional parameters. The primary differences are manufacturer (Souriau-Sunbank vs. Glenair) and inventory availability (21700 vs. 741 pieces). Selection between these parts depends on procurement lead time and supplier preference.

Q: Why does D38999/26WD18SNLC have a lower maximum operating temperature?

A: The D38999/26WD18SNLC is specified as a plug housing assembly with a maximum operating temperature of 175°C, compared to 200°C for the original part. This part is suitable for applications operating within the 175°C limit. Applications requiring operation above 175°C require selection of alternative substitutes.

Q: Are all substitute parts RoHS non-compliant like the original?

A: The D38999/26WD18SN and D38999/26WD18SNLC are confirmed RoHS non-compliant, matching the original part. The D38999/26FD18SN and CTVS06RF-15-18S do not specify RoHS status in available documentation. For applications with RoHS compliance requirements, contact manufacturers directly for current certification status.

Q: What is the significance of the EAR99 classification?

A: EAR99 classification indicates the part is subject to U.S. export control regulations but does not require a license for most commercial destinations. All substitute parts carry this same classification, maintaining regulatory consistency with the original part for aerospace and military applications.

Q: Can these connectors be used interchangeably in mated pairs?

A: Yes. All substitute parts are MIL-DTL-38999 Series III compliant 18-position D-size connectors. Plugs and receptacles from different manufacturers within this specification family are mechanically and electrically interchangeable.

Q: What is the MSL rating and why does it matter?

A: MSL 1 (Unlimited) indicates the part has unlimited shelf life and requires no special moisture control during storage or handling. All substitute parts carry this rating, eliminating moisture sensitivity concerns for inventory management and long-term storage.

Q: Which substitute offers the best long-term availability?

A: D38999/26WD18SN (Souriau-Sunbank by Eaton) offers the highest current inventory (21700 pieces) and active product status, providing the strongest assurance of continued availability for future procurement requirements.
