Substitution of the ACT96WD18SN is determined by strict adherence to the following critical parameters:

Mandatory Compatibility Parameters:

• Connector Type: Plug with Female Sockets
• Number of Positions: 18
• Shell Size - Insert: 15-18
• Shell Size, MIL: D
• Mounting Type: Free Hanging (In-Line)
• Termination: Crimp
• Fastening Type: Threaded
• Shielding: Shielded
• Operating Temperature Range: -65°C ~ 175°C
• Current Rating: 7.5A
• Ingress Protection: Environment Resistant

Substitute parts must satisfy all mandatory parameters to ensure mechanical fit, electrical performance, and operational reliability in aerospace and military applications. The substitute parts identified below meet these criteria across different manufacturers within the MIL-DTL-38999 Series III specification family.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

D38999/26WD18SN (Souriau-Sunbank by Eaton) is the preferred substitute. This part maintains all mandatory compatibility parameters and is currently in active production status with 21,700 units in stock. It carries identical electrical and mechanical specifications, including the 7.5A current rating, -65°C to 175°C operating temperature range, and MIL-DTL-38999 Series III compliance. The part is RoHS non-compliant and REACH unaffected, consistent with the original ACT96WD18SN.

D38999/26FD18SN (Glenair) is an alternative substitute meeting all mandatory compatibility parameters. This part is active with 741 units in stock. It maintains identical specifications for connector type, position count, shell size, mounting configuration, and environmental ratings. REACH status is unaffected, and ECCN classification is EAR99.

Secondary Substitute (Housing Configuration):

D38999/26WD18SNLC (Amphenol Aerospace Operations) is a plug housing variant designed for female sockets. This part is active with 683 units in stock and meets all mandatory parameters. The key distinction is that this part is a connector housing without integrated contacts, requiring separate contact assembly. It is suitable for applications requiring housing replacement or custom contact configurations while maintaining mechanical and electrical interface compatibility.

Alternative Substitute (Limited Specification Data):

CTVS06RF-15-18S (Amphenol Aerospace Operations) is listed as a substitute with 986 units in stock and active status. Complete specification data is not fully provided in the input parameters; however, it meets the core position count (18), shell size (15-18, D), and mounting type (Free Hanging In-Line) requirements. Detailed compliance verification is required before selection for critical applications.

Selection Criteria:

For direct replacement applications requiring immediate availability and full specification alignment, D38999/26WD18SN is recommended due to highest inventory levels (21,700 units) and confirmed active production status. For applications where housing-only replacement is required, D38999/26WD18SNLC provides equivalent mechanical interface with contact assembly flexibility. All recommended substitutes maintain MIL-DTL-38999 Series III compliance and aerospace/military application suitability.

Frequently Asked Questions (FAQ)

Q: Can D38999/26WD18SN be used as a direct replacement for ACT96WD18SN?

A: Yes. D38999/26WD18SN meets all mandatory compatibility parameters: 18-position plug with female sockets, MIL-DTL-38999 Series III compliance, 7.5A current rating, -65°C to 175°C operating temperature, crimp termination, threaded fastening, and shielded construction. Mechanical fit and electrical performance are equivalent.

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

A: Both parts are 18-position plugs with female sockets meeting identical electrical and mechanical specifications. The primary difference is manufacturer: D38999/26WD18SN is supplied by Souriau-Sunbank by Eaton with 21,700 units in stock, while D38999/26FD18SN is supplied by Glenair with 741 units in stock. Both are active products with equivalent performance characteristics.

Q: Why is D38999/26WD18SNLC listed as a substitute if it is a housing-only component?

A: D38999/26WD18SNLC is a plug housing designed for female sockets that maintains all mandatory mechanical and environmental compatibility parameters. It is suitable for applications requiring housing replacement or custom contact assembly. This part does not include integrated contacts and requires separate contact installation, distinguishing it from complete connector assemblies.

Q: Are all substitute parts RoHS compliant?

A: No. The ACT96WD18SN and all primary substitutes (D38999/26WD18SN, D38999/26FD18SN, D38999/26WD18SNLC) are RoHS non-compliant. This is consistent with military and aerospace connector specifications where RoHS exemptions apply. Compliance status should be verified against specific application requirements.

Q: What is the significance of the ECCN classification EAR99?

A: ECCN EAR99 classification indicates that these connectors are subject to export control regulations under the Export Administration Regulations (EAR). All identified substitutes carry this classification, consistent with military-grade circular connector specifications. Export authorization requirements must be verified for international applications.

Q: Can CTVS06RF-15-18S be used interchangeably with ACT96WD18SN?

A: CTVS06RF-15-18S meets core position count (18), shell size (15-18, D), and mounting type (Free Hanging In-Line) requirements. Complete electrical and mechanical specification data is not fully provided in available documentation. Detailed specification verification is required before confirming interchangeability for specific applications.

Q: What is the difference between Moisture Sensitivity Level (MSL) ratings of the substitute parts?

A: ACT96WD18SN, D38999/26FD18SN, and D38999/26WD18SNLC carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. D38999/26WD18SN carries MSL Not Applicable, indicating the part does not require moisture sensitivity classification. Both ratings are acceptable for aerospace and military applications; MSL classification does not affect connector performance in these applications.

Q: What inventory levels are available for each substitute?

A: D38999/26WD18SN: 21,700 units; CTVS06RF-15-18S: 986 units; D38999/26FD18SN: 741 units; D38999/26WD18SNLC: 683 units. Inventory levels should be verified with suppliers for current availability, as stock quantities are subject to change.
