Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACT96MF11SN is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 11
• Shell Size - Insert: 19-11
• Shell Size, MIL: F
• Series: MIL-DTL-38999 Series III
• Connector Type: Plug configuration for female sockets
• Mounting Type: Free Hanging (In-Line)
• Termination: Crimp
• Fastening Type: Threaded
• Shielding: Shielded
• Ingress Protection: Environment Resistant
• Applications: Aerospace, Military

The substitute part D38999/26WF11SNLC meets these mandatory parameters, establishing functional equivalence for direct replacement in applications requiring MIL-DTL-38999 Series III compliance. Both parts are designated for identical shell sizes, position counts, and mounting configurations.

Parameter Comparison

Engineering Selection Recommendations

ACT96MF11SN (Original Part): The ACT96MF11SN is discontinued at DiGi Electronics. Existing inventory of 996 pieces is available through current stock channels. This part is RoHS non-compliant and designated for aerospace and military applications. The operating temperature range extends to 200°C, providing thermal capability for high-temperature environments.

D38999/26WF11SNLC (Substitute Part): The D38999/26WF11SNLC is an active product from Amphenol Aerospace Operations with 680 pieces in current inventory. This substitute maintains MIL-DTL-38999 Series III compliance and identical mechanical and electrical interface specifications. The operating temperature range is -65°C ~ 175°C, which is suitable for standard aerospace and military applications within this thermal envelope. The part is RoHS non-compliant, consistent with military connector standards. Active product status ensures continued availability and supply chain reliability.

Selection between these parts depends on application-specific thermal requirements. For applications requiring operation above 175°C, the original ACT96MF11SN specification must be maintained. For applications within the -65°C ~ 175°C range, the D38999/26WF11SNLC provides equivalent functionality with active product support.

Frequently Asked Questions (FAQ)

Q: Can D38999/26WF11SNLC directly replace ACT96MF11SN in all applications?

A: Direct replacement is valid for applications operating within the -65°C ~ 175°C temperature range. Both parts conform to MIL-DTL-38999 Series III specifications with identical shell sizes (F, 19-11), position counts (11), mounting configurations (Free Hanging In-Line), and termination methods (Crimp). If the application requires operation above 175°C, the original ACT96MF11SN specification must be retained.

Q: What are the key compatibility parameters for these connectors?

A: Compatibility is established through: 11-position configuration, Shell Size F with 19-11 insert designation, MIL-DTL-38999 Series III compliance, threaded fastening, shielded construction, crimp termination, and free-hanging in-line mounting. Both parts meet these parameters identically.

Q: Are there differences in shell material between these parts?

A: Yes. The ACT96MF11SN features a composite shell with nickel finish, while the D38999/26WF11SNLC uses an aluminum shell with cadmium finish. Both materials and finishes are compliant with MIL-DTL-38999 Series III specifications for this connector class.

Q: What is the significance of the "Contacts Not Included" note on the substitute part?

A: The D38999/26WF11SNLC is supplied as a plug housing without pre-installed contacts. Crimp contacts must be separately sourced and installed. The original ACT96MF11SN specification should clarify whether contacts are included in the assembly to ensure complete system compatibility.

Q: Are both parts suitable for aerospace and military applications?

A: Yes. Both the ACT96MF11SN and D38999/26WF11SNLC are designated for aerospace and military applications. Both are RoHS non-compliant, which is standard for military-grade connectors. Both maintain MIL-DTL-38999 Series III compliance and environment-resistant ingress protection ratings.

Q: What is the difference in current rating between these parts?

A: The ACT96MF11SN is rated for 13A. The D38999/26WF11SNLC specification does not provide a current rating in the available data. Current capacity should be verified against the specific contact size and material specifications for the substitute part before final selection.
