Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96MD35SN is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Number of Positions: 37
• Shell Size - Insert: 15-35
• Shell Size, MIL: D
• Connector Type: Plug, Female Sockets
• Termination: Crimp
• Fastening Type: Threaded
• Mounting Type: Free Hanging (In-Line)
• Shielding: Shielded
• Current Rating: 5A
• Contact Finish - Mating: Gold
• Operating Temperature Range: -65°C ~ 200°C (or compatible subset)
• Series Compliance: MIL-DTL-38999 Series III

Substitute parts are grouped into two categories:

Category A - Direct Electrical and Mechanical Equivalents: Parts that match all primary substitution criteria and maintain identical connector type, position count, shell size, and performance specifications. These parts are interchangeable at the connector interface level.

Category B - Housing and Assembly Variants: Parts that share the same shell size, position count, and MIL-DTL-38999 Series III compliance but differ in form factor (housing vs. insert) or fastening features. These require system-level compatibility assessment.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - D38999/26MD35SN (TE Connectivity Deutsch Connectors)

The D38999/26MD35SN is the preferred substitute for the ACT96MD35SN. Both parts are manufactured by TE Connectivity Deutsch Connectors and share identical electrical and mechanical specifications across all critical parameters: 37 positions, shell size D (15-35 insert), crimp termination, threaded fastening, free-hanging mounting, shielding, 5A current rating, gold contact finish, and -65°C to 200°C operating temperature. The D38999/26MD35SN is ROHS3 compliant and REACH affected, providing improved regulatory compliance compared to the original part. Current inventory of 736 units supports procurement requirements.

Secondary Substitute - D38999/26FD35SN (Glenair)

The D38999/26FD35SN manufactured by Glenair meets all electrical and mechanical equivalence criteria. This part maintains identical position count, shell size, termination method, fastening type, mounting configuration, shielding, current rating, contact finish, and operating temperature range. The part is currently active and carries REACH unaffected status. Inventory of 1063 units is available. Selection of this substitute requires confirmation of Glenair connector compatibility within the specific application context.

Tertiary Substitute - CTVS06RF-15-35S (Amphenol Aerospace Operations)

The CTVS06RF-15-35S is an active Amphenol Aerospace Operations connector meeting the core substitution criteria: 37 positions, shell size D (15-35 insert), crimp termination, threaded fastening, free-hanging mounting, shielding, 5A current rating, gold contact finish, and -65°C to 200°C operating temperature. Inventory of 829 units is available. This substitute is suitable for applications where Amphenol Aerospace connectors are qualified.

Housing Assembly Variant - D38999/26WD35SNLC (Amphenol Aerospace Operations)

The D38999/26WD35SNLC is a plug housing assembly variant manufactured by Amphenol Aerospace Operations. This part shares the same shell size D, 37-position configuration, and MIL-DTL-38999 Series III compliance. However, it is a housing component (contacts not included) with a self-locking coupling nut and operates at -65°C to 175°C (5°C lower maximum than the original part). This variant is suitable only for applications requiring a housing-only assembly and where the reduced upper operating temperature is acceptable.

Regulatory and Compliance Considerations

The original ACT96MD35SN is RoHS non-compliant. The D38999/26MD35SN provides ROHS3 compliance and is REACH affected, making it the preferred choice for applications subject to RoHS3 and REACH regulations. The D38999/26FD35SN carries REACH unaffected status. All substitute parts maintain the EAR99 ECCN classification and 8536.69.4020 HTSUS code of the original part.

Frequently Asked Questions (FAQ)

Q: Can the D38999/26MD35SN be used as a direct replacement for the ACT96MD35SN?

A: Yes. The D38999/26MD35SN is a direct electrical and mechanical equivalent. Both parts share identical specifications for position count (37), shell size (D, 15-35 insert), connector type (plug with female sockets), termination (crimp), fastening (threaded), mounting (free-hanging in-line), shielding, current rating (5A), contact finish (gold), and operating temperature range (-65°C to 200°C). The D38999/26MD35SN is manufactured by the same company (TE Connectivity Deutsch Connectors) and provides improved regulatory compliance through ROHS3 certification.

Q: What is the difference between the ACT96MD35SN and D38999/26WD35SNLC?

A: The D38999/26WD35SNLC is a plug housing assembly, not a complete connector plug. It includes a self-locking coupling nut and does not include contacts. The original ACT96MD35SN is a complete plug connector with female sockets and integrated contacts. Additionally, the D38999/26WD35SNLC operates at -65°C to 175°C, which is 25°C lower than the ACT96MD35SN maximum operating temperature of 200°C. The D38999/26WD35SNLC is suitable only for applications requiring a housing-only assembly.

Q: Are all substitute parts compatible with existing mating connectors designed for the ACT96MD35SN?

A: All substitute parts listed (D38999/26MD35SN, D38999/26FD35SN, and CTVS06RF-15-35S) maintain identical shell size D, 37-position configuration, and MIL-DTL-38999 Series III compliance. These parts are mechanically and electrically compatible with mating connectors designed for the ACT96MD35SN. The D38999/26WD35SNLC housing variant is not a complete connector and requires separate contact insertion.

Q: What is the significance of the operating temperature difference in the D38999/26WD35SNLC?

A: The D38999/26WD35SNLC operates at -65°C to 175°C, while the ACT96MD35SN operates at -65°C to 200°C. This 25°C reduction in maximum operating temperature may be critical for applications requiring sustained operation at elevated temperatures. The D38999/26WD35SNLC is not suitable for applications requiring the full -65°C to 200°C temperature range.

Q: How do RoHS and REACH compliance statuses affect substitute selection?

A: The original ACT96MD35SN is RoHS non-compliant. The D38999/26MD35SN provides ROHS3 compliance and is REACH affected, making it suitable for applications subject to RoHS3 and REACH regulations. The D38999/26FD35SN is REACH unaffected. The D38999/26WD35SNLC is RoHS non-compliant and REACH affected. Selection should align with the regulatory requirements of the target application and end-use market.

Q: What inventory levels are available for each substitute part?

A: Current inventory levels are as follows: D38999/26MD35SN (736 units), D38999/26FD35SN (1063 units), CTVS06RF-15-35S (829 units), and D38999/26WD35SNLC (865 units). The original ACT96MD35SN has 1133 units in stock. Inventory levels should be confirmed with the supplier for time-sensitive procurement requirements.

Q: Are there any differences in shell material or finish between the substitute parts?

A: The ACT96MD35SN, D38999/26MD35SN, and D38999/26FD35SN feature composite shell material with nickel finish. The D38999/26WD35SNLC features aluminum shell material with cadmium finish and olive drab housing color. These material and finish differences may affect mechanical properties, environmental resistance, and weight characteristics in specific applications.

Q: Can the CTVS06RF-15-35S be used interchangeably with the ACT96MD35SN?

A: The CTVS06RF-15-35S meets all core electrical and mechanical substitution criteria: 37 positions, shell size D (15-35 insert), crimp termination, threaded fastening, free-hanging mounting, shielding, 5A current rating, gold contact finish, and -65°C to 200°C operating temperature. However, it is manufactured by Amphenol Aerospace Operations rather than TE Connectivity Deutsch Connectors. Interchangeability depends on whether Amphenol Aerospace connectors are qualified for the specific application. System-level compatibility assessment is required.
