Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96WE26SA is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Connector Type: Plug, Female Sockets
• Number of Positions: 26
• Shell Size - Insert: 17-26
• Shell Size, MIL: E
• Termination: Crimp
• Fastening Type: Threaded
• Orientation: A
• Shell Finish: Olive Drab Cadmium
• Contact Finish - Mating: Gold
• Contact Finish Thickness - Mating: 50.0µin (1.27µm)
• Shielding: Shielded
• Operating Temperature: -65°C ~ 175°C
• Series Qualification: MIL-DTL-38999 Series III

The substitute parts identified maintain these critical parameters, ensuring mechanical and electrical interchangeability within the specified application envelope. Variations in shell material composition and manufacturer do not affect functional compatibility when all critical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

D38999/26FE26SA (Souriau-Sunbank by Eaton): This substitute maintains full mechanical and electrical compatibility with the ACT96WE26SA. The part is currently active in inventory with 1,052 units available. The D38999/26FE26SA achieves ROHS3 compliance and REACH unaffected status, providing regulatory advantages for new designs or applications with environmental compliance requirements. Selection of this substitute is appropriate for applications where RoHS compliance is mandated.

D38999/26WE26SA (Amphenol Aerospace Operations): This substitute maintains full mechanical and electrical compatibility with the ACT96WE26SA. The part is currently active in inventory with 856 units available. The D38999/26WE26SA features aluminum shell material construction and includes a coupling nut feature. This substitute maintains RoHS non-compliant status consistent with the original part. The Tri-Start™ TV series designation indicates aerospace-grade qualification. Selection of this substitute is appropriate for applications requiring direct functional equivalence with extended aerospace and aviation application support.

Both substitute parts satisfy the critical parameters required for direct replacement within MIL-DTL-38999 Series III specifications. Selection between substitutes depends on regulatory compliance requirements and material composition preferences.

Frequently Asked Questions (FAQ)

Q: Can D38999/26FE26SA and D38999/26WE26SA be used interchangeably with ACT96WE26SA?

A: Yes. Both substitute parts maintain all critical parameters including connector type, position count, shell size, termination method, fastening type, shell finish, contact finish specifications, shielding, and operating temperature range. All three parts are qualified to MIL-DTL-38999 Series III specifications.

Q: What is the difference between the shell materials in these connectors?

A: The ACT96WE26SA features composite shell material. The D38999/26WE26SA features aluminum shell material. Both materials are compatible with the specified operating temperature range and environmental resistance requirements. Material selection does not affect electrical or mechanical interchangeability.

Q: Does RoHS compliance status affect substitution compatibility?

A: RoHS compliance status does not affect electrical or mechanical compatibility. The D38999/26FE26SA is ROHS3 compliant, while the ACT96WE26SA and D38999/26WE26SA are RoHS non-compliant. Selection based on RoHS status depends on application regulatory requirements, not on connector functionality.

Q: Are the crimp termination specifications identical across all three parts?

A: Yes. All three parts specify crimp termination with identical contact finish thickness of 50.0µin (1.27µm) and gold mating surface finish. Crimp tool compatibility and contact specifications are equivalent.

Q: What is the significance of the 26-position configuration?

A: The 26-position configuration defines the contact count and shell size designation (17-26 insert, E shell size per MIL-DTL-38999). This configuration is maintained across all substitute parts, ensuring pin-for-pin compatibility in mated assemblies.

Q: Can these connectors be used in applications outside aerospace and military?

A: The connectors are specified for aerospace and military applications. The D38999/26WE26SA extends application support to aviation and marine environments. Use in other applications requires verification that the operating temperature range (-65°C ~ 175°C), current rating (7.5A for the main part), and environmental resistance specifications meet application requirements.

Q: What is the significance of the threaded fastening type?

A: Threaded fastening provides secure mated connection through coupling nut engagement. This fastening method is maintained across all substitute parts, ensuring equivalent connection reliability and vibration resistance in aerospace and military applications.
