Parameter Comparison

Engineering Selection Recommendations

D38999/26FE35SN (Glenair): This substitute maintains active product status and shares the MIL-DTL-38999 Series III classification. However, detailed electrical and mechanical specifications are not fully documented in available data. Verification of shell size, mounting configuration, and termination method is required before selection.

D38999/26ME35SN (Souriau-Sunbank by Eaton): This substitute provides the most complete parameter alignment with the original ACT96WE35SN. It maintains 55-position configuration, shell size E (17-35), crimp termination, threaded fastening, and gold-plated contacts at 50.0µin thickness. Operating temperature extends to 200°C, exceeding the original specification. The part is currently active in production and carries RoHS non-compliant status consistent with the original. This substitute is suitable for direct replacement in applications requiring MIL-DTL-38999 Series III compliance.

D38999/26WE35SNLC (Amphenol Aerospace Operations): This substitute is a plug housing component designed for female sockets and includes self-locking coupling nut features. It maintains the 55-position, shell size E configuration and MIL-DTL-38999 Series III compliance. The part is currently active and carries REACH Affected status. Note that contacts are not included with this housing component; contact procurement must be addressed separately.

Frequently Asked Questions (FAQ)

Q: Can D38999/26FE35SN be used as a direct replacement for ACT96WE35SN?

A: D38999/26FE35SN shares the 55-position circular connector classification and MIL-DTL-38999 Series III series designation. However, complete electrical and mechanical parameter documentation is not available. Confirmation of shell size (17-35), shell size MIL (E), mounting type (free hanging in-line), termination method (crimp), and fastening type (threaded) is necessary before confirming substitution eligibility.

Q: What is the primary advantage of D38999/26ME35SN over the original ACT96WE35SN?

A: D38999/26ME35SN provides identical core specifications while maintaining active product status. The extended operating temperature range (-65°C to 200°C versus -65°C to 175°C) offers enhanced thermal capability. Both parts are RoHS non-compliant and carry identical moisture sensitivity levels, ensuring regulatory consistency.

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

A: D38999/26WE35SNLC is a plug housing component only. Contacts are not included and must be procured separately. This part is suitable for applications where housing replacement or assembly customization is required, but it does not provide a complete plug assembly equivalent to ACT96WE35SN.

Q: What packaging differences exist among the substitute parts?

A: ACT96WE35SN is supplied in standard packaging. D38999/26FE35SN is packaged in bulk. D38999/26ME35SN is supplied in bag packaging. D38999/26WE35SNLC is packaged in bulk. Packaging differences do not affect electrical or mechanical compatibility but may influence procurement and inventory management procedures.

Q: Are all substitute parts compliant with the same regulatory standards as the original?

A: All substitute parts maintain RoHS non-compliant status consistent with the original ACT96WE35SN. All parts carry moisture sensitivity level 1 (unlimited). D38999/26WE35SNLC carries REACH Affected status, whereas the original and other substitutes do not specify REACH status. Regulatory compliance verification for specific application requirements is recommended.

Q: What is the current inventory status of substitute parts?

A: D38999/26FE35SN: 1042 pieces in stock. D38999/26ME35SN: 908 pieces in stock. D38999/26WE35SNLC: 995 pieces in stock. All substitute parts are available in active production quantities.
