Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96WD18SN-3025 is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• 18-position connector configuration
• Plug connector type with female sockets
• Shell size D (15-18 insert size)
• Free hanging (in-line) mounting
• Threaded fastening
• Shielded design
• Crimp termination
• Operating temperature range -65°C to 175°C
• MIL-DTL-38999 Series III compliance

Acceptable Variations:

• Manufacturer identity (TE Connectivity, Glenair, Souriau-Sunbank, Amphenol)
• Shell material composition (composite or aluminum)
• Inventory availability
• Product status (active vs. discontinued)

All substitute parts listed maintain electrical and mechanical compatibility within the MIL-DTL-38999 Series III standard and support the same 18-position, female socket, crimp-terminated configuration required for direct system integration.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

The D38999/26WD18SN manufactured by Souriau-Sunbank by Eaton represents the highest compatibility substitute. This part maintains all critical electrical and mechanical parameters of the ACT96WD18SN-3025, including 18-position configuration, MIL-DTL-38999 Series III compliance, threaded fastening, and shielded design. The part is currently active with substantial inventory availability (21700 units). RoHS non-compliance status matches the original specification, and ECCN/HTSUS classifications are identical.

The D38999/26WD18SNLC manufactured by Amphenol Aerospace Operations provides an alternative with confirmed operating temperature range (-65°C to 175°C) and environment resistant ingress protection. This part is designated as a plug housing for female sockets and is currently active. The HTSUS classification differs (8538.90.8180 vs. 8536.69.4020), reflecting its housing-only configuration without integrated contacts.

Secondary Substitutes (Active Status, Partial Data):

The D38999/26FD18SN manufactured by Glenair maintains the 18-position, MIL-DTL-38999 Series III configuration with active product status. Complete parameter specifications are not provided in the available data; however, the part number structure indicates MIL-DTL-38999 compliance. REACH unaffected status is documented.

The CTVS06RF-15-18S manufactured by Amphenol Aerospace Operations is listed as an active substitute with 986 units in inventory. Limited technical specifications are provided; series designation is not specified in available documentation.

Compliance Considerations:

All primary substitutes maintain EAR99 ECCN classification and RoHS non-compliant status consistent with the original part. Selection should account for specific system requirements regarding contact finish specifications, shell material composition, and housing configuration (composite vs. aluminum).

Frequently Asked Questions (FAQ)

Q: Can the D38999/26WD18SN directly replace the ACT96WD18SN-3025 in existing assemblies?

A: Yes. Both parts conform to MIL-DTL-38999 Series III specifications with identical 18-position, female socket, crimp-terminated configurations. Shell size D (15-18 insert) and threaded fastening are equivalent. The D38999/26WD18SN is manufactured by Souriau-Sunbank by Eaton and is currently active with high inventory availability.

Q: What is the difference between the D38999/26WD18SN and D38999/26WD18SNLC?

A: The D38999/26WD18SNLC is designated as a plug housing for female sockets without integrated contacts. The standard D38999/26WD18SN includes the complete connector assembly. Selection depends on whether contacts require separate procurement or are already integrated into the system design.

Q: Are all substitute parts RoHS compliant?

A: No. The primary substitutes D38999/26WD18SN and D38999/26WD18SNLC are RoHS non-compliant, matching the original ACT96WD18SN-3025 specification. RoHS compliance status for D38999/26FD18SN and CTVS06RF-15-18S is not specified in available documentation.

Q: What is the significance of the different HTSUS codes?

A: The HTSUS code 8536.69.4020 applies to complete connector assemblies (ACT96WD18SN-3025, D38999/26WD18SN, D38999/26FD18SN). The code 8538.90.8180 applies to the D38999/26WD18SNLC housing-only configuration. This distinction affects tariff classification and import/export documentation.

Q: Can I use the CTVS06RF-15-18S as a substitute?

A: The CTVS06RF-15-18S is listed as an equivalent part with matching 18-position and shell size D specifications. However, complete technical specifications are not provided in available documentation. Verification of mounting type, termination method, and fastening type is required before system integration.

Q: What inventory considerations should guide part selection?

A: The D38999/26WD18SN offers the highest inventory availability at 21700 units. The D38999/26WD18SNLC (683 units), D38999/26FD18SN (741 units), and CTVS06RF-15-18S (986 units) provide alternative sources with lower stock levels. Selection should account for lead time requirements and supply chain continuity.

Q: Are there any temperature rating differences between substitutes?

A: The ACT96WD18SN-3025 and D38999/26WD18SNLC both specify -65°C to 175°C operating temperature range. Operating temperature specifications are not provided for D38999/26WD18SN, D38999/26FD18SN, or CTVS06RF-15-18S in available documentation.

Q: What contact finish specifications apply to these substitutes?

A: The ACT96WD18SN-3025 specifies gold contact finish for mating surfaces. Contact finish specifications are not provided for substitute parts in available documentation. System requirements for contact finish should be confirmed with the connector manufacturer before final selection.
