Key Parameters

Substitute Part Grouping Explanation

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

Primary Substitution Criteria:

• Connector type: Plug with female sockets
• Number of positions: 55
• Shell size (insert and MIL designation): 17-35 and E
• Series compliance: MIL-DTL-38999 Series III
• Mounting configuration: Free Hanging (In-Line)
• Termination method: Crimp
• Fastening mechanism: Threaded
• Shielding: Shielded
• Current rating: 5A
• Operating temperature range: -65°C ~ 200°C
• Contact finish: Gold with 50.0µin (1.27µm) thickness
• Contact material: Copper Alloy

The substitute parts identified maintain these core electrical and mechanical parameters, ensuring functional interchangeability within systems designed for the ACT96ME35SN. Variations in secondary attributes such as manufacturer, packaging, shell material composition, or ingress protection rating do not affect substitution eligibility when primary parameters remain constant.

Engineering Selection Recommendations

D38999/26FE35SN (Glenair)

This substitute maintains MIL-DTL-38999 Series III compliance and is currently active in production. Inventory availability is 1,042 units. The part is supplied in bulk packaging. Limited technical specification data is provided in the available documentation; however, the part number designation indicates compatibility with the 55-position, size E configuration. Selection of this substitute requires confirmation of undocumented parameters through manufacturer technical documentation.

D38999/26ME35SN (Souriau-Sunbank by Eaton)

This substitute provides complete parameter equivalence to the ACT96ME35SN across all specified electrical and mechanical characteristics. The part is actively produced and maintains MIL-DTL-38999 Series III compliance. Inventory availability is 908 units. The connector features enhanced ingress protection (IP67 - Dust Tight, Waterproof) compared to the original part's environment-resistant rating. Operating temperature range matches the original specification (-65°C ~ 200°C). This substitute is suitable for direct replacement in aerospace, aviation, marine, and military applications.

D38999/26WE35SNLC (Amphenol Aerospace Operations)

This substitute is a plug housing component designed for female sockets and maintains the 55-position, size E configuration within the MIL-DTL-38999 Series III standard. The part is actively produced with 995 units in inventory. The operating temperature range is -65°C ~ 175°C, which is 25°C lower than the original part's maximum specification. The housing features self-locking coupling nut functionality and is manufactured from aluminum with cadmium finish. This component is supplied without contacts included. Selection of this substitute is appropriate when housing replacement is required; however, contact compatibility must be verified independently.

Frequently Asked Questions (FAQ)

Q: Can D38999/26FE35SN be used as a direct replacement for ACT96ME35SN?

A: D38999/26FE35SN is designated as a substitute based on part number equivalence within the MIL-DTL-38999 Series III standard. However, complete technical specifications for this Glenair component are not fully documented in available data. Verification of undocumented parameters through Glenair technical documentation is necessary before implementation in critical applications.

Q: What is the primary advantage of D38999/26ME35SN over the original ACT96ME35SN?

A: D38999/26ME35SN provides complete parameter equivalence with the original part while maintaining active production status. The substitute offers enhanced ingress protection (IP67 rating) and is manufactured by Souriau-Sunbank by Eaton, an established supplier in aerospace and military connector applications. All electrical and mechanical specifications remain identical to the original.

Q: Is D38999/26WE35SNLC a complete connector assembly?

A: D38999/26WE35SNLC is a plug housing component only and does not include contacts. This part is suitable for applications requiring housing replacement or assembly of custom connector configurations. Contact elements must be sourced separately and verified for compatibility with the housing.

Q: What is the significance of the operating temperature difference in D38999/26WE35SNLC?

A: D38999/26WE35SNLC operates within the range -65°C ~ 175°C, which is 25°C lower than the original ACT96ME35SN specification of -65°C ~ 200°C. This difference may be significant in applications requiring operation at elevated temperatures above 175°C. System thermal requirements must be evaluated before selecting this substitute.

Q: Are all substitute parts RoHS non-compliant like the original?

A: Yes, all identified substitutes maintain RoHS non-compliant status consistent with the original ACT96ME35SN. This compliance status reflects the military and aerospace application requirements for these MIL-DTL-38999 Series III connectors.

Q: What packaging options are available for these substitutes?

A: D38999/26FE35SN is supplied in bulk packaging. D38999/26ME35SN is supplied in bag packaging. D38999/26WE35SNLC is supplied in bulk packaging. Packaging selection may affect procurement logistics and inventory management requirements.

Q: Do all substitutes maintain the same moisture sensitivity level?

A: Yes, all identified substitutes maintain Moisture Sensitivity Level 1 (Unlimited), consistent with the original ACT96ME35SN. This rating indicates no special moisture control measures are required during storage or handling.

Q: Can these substitutes be intermixed in the same system?

A: Substitutes should be selected based on specific application requirements and maintained consistently throughout a system design. While all substitutes maintain core MIL-DTL-38999 Series III compatibility, variations in secondary parameters such as ingress protection rating, operating temperature range, or housing material may affect system performance. Engineering evaluation is required to determine appropriate substitute selection for each application context.
