Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96ME35SN-3025 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Connector type (Plug, Female Sockets)
• Number of positions (55)
• Shell size and MIL designation (17-35, Size E)
• Mounting configuration (Free Hanging, In-Line)
• Termination method (Crimp)
• Fastening type (Threaded)
• Shielding requirement (Shielded)
• Current rating (5A)
• Operating temperature range (-65°C ~ 200°C)
• Contact material and finish (Copper Alloy, Gold plating)
• Insert material (Thermoplastic)
• MIL-DTL-38999 Series III compliance

The substitute parts identified maintain these core parameters while originating from alternative manufacturers within the military connector ecosystem. Substitutes are grouped by their adherence to the MIL-DTL-38999 Series III standard and compatibility with the specified electrical and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

D38999/26ME35SN (Souriau-Sunbank by Eaton)

This substitute provides the highest parameter alignment with the ACT96ME35SN-3025. The D38999/26ME35SN maintains identical specifications across connector type, position count, shell size, mounting configuration, termination method, fastening type, orientation, shell material, shell finish, contact finish, shielding, current rating, operating temperature range, contact material, insert material, and MIL-DTL-38999 Series III compliance. The part is currently active in production with 908 units in stock. The enhanced ingress protection rating (IP67) provides additional environmental sealing capability. This part is suitable for direct substitution in aerospace, aviation, marine, and military applications.

D38999/26WE35SNLC (Amphenol Aerospace Operations)

This substitute is a plug housing variant designed for female sockets, maintaining the 55-position configuration, shell size, mounting type, fastening type, orientation, and shielding requirements. The part features a self-locking coupling nut and operates across the -65°C to 175°C temperature range. The aluminum shell with cadmium finish differs from the composite nickel-finished original. This part is currently active with 995 units in stock and is suitable for applications where the housing component requires replacement or upgrade. Note that contacts are not included with this part.

D38999/26FE35SN (Glenair)

This substitute maintains the 55-position circular connector configuration and MIL-DTL-38999 Series III compliance. Limited detailed specifications are provided in the available data. The part is currently active with 1042 units in stock. Detailed parameter verification is required before implementation in critical applications.

All substitute parts carry identical RoHS non-compliance status and Moisture Sensitivity Level 1 (Unlimited) ratings as the original component. All parts are classified under ECCN EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can D38999/26ME35SN directly replace ACT96ME35SN-3025 in existing assemblies?

A: Yes. The D38999/26ME35SN maintains identical electrical and mechanical parameters across all critical specifications including connector type, position count, shell size, mounting configuration, termination method, fastening type, shielding, current rating, operating temperature range, contact material, and insert material. Both parts comply with MIL-DTL-38999 Series III standards.

Q: What is the difference between the D38999/26ME35SN and D38999/26WE35SNLC substitutes?

A: The D38999/26ME35SN is a complete plug connector with female sockets and integrated housing. The D38999/26WE35SNLC is a plug housing component designed for female sockets, supplied without contacts. The D38999/26WE35SNLC features a self-locking coupling nut and operates to 175°C maximum, compared to 200°C for the D38999/26ME35SN. The D38999/26WE35SNLC housing is aluminum with cadmium finish rather than composite with nickel finish.

Q: Are there packaging differences between the substitute parts?

A: Yes. The ACT96ME35SN-3025 is supplied in unspecified packaging. The D38999/26ME35SN is supplied in bag packaging. The D38999/26FE35SN and D38999/26WE35SNLC are supplied in bulk packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: What is the operating temperature difference between the original and D38999/26WE35SNLC?

A: The ACT96ME35SN-3025 operates from -65°C to 200°C. The D38999/26WE35SNLC operates from -65°C to 175°C. This 25°C reduction in maximum operating temperature must be evaluated against specific application requirements.
