AFD56-18-11PN Equivalent & Substitute Parts

Part Overview

The AFD56-18-11PN is an 11-position circular connector plug with male pins manufactured by TE Connectivity Deutsch Connectors. This connector is designed for free-hanging (in-line) applications and features crimp termination with bayonet lock fastening. The part is compliant with MIL-DTL-26482 G Series II specifications and is rated for operation across -55°C to 200°C. The AFD56-18-11PN is discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing system maintenance, repair, and new production applications requiring compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD56-18-11PN is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 11
• Shell Size - Insert: 18-11
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Orientation: N (Normal)
• Operating Temperature Range: -55°C ~ 200°C
• Termination Method: Crimp

The PV76W18-11PL qualifies as a substitute part because it matches all mandatory parameters. Both connectors accommodate 11-position configurations with identical shell sizing, employ bayonet lock fastening, support free-hanging installation, and operate within the same temperature envelope. Both utilize crimp termination and maintain environment-resistant ingress protection suitable for aviation, automotive, and military applications.

Parameter Comparison

Engineering Selection Recommendations

AFD56-18-11PN Availability: The AFD56-18-11PN is discontinued at DiGi Electronics. Existing inventory of 1,098 pieces is available through current stock channels, but long-term procurement should not rely on this part number for new production or future system builds.

PV76W18-11PL as Active Substitute: The PV76W18-11PL is an active product manufactured by ITT Cannon, LLC with 685 pieces in current inventory. This substitute maintains full mechanical and electrical compatibility with the AFD56-18-11PN across all critical parameters: 11-position configuration, 18-11 shell sizing, bayonet lock fastening, free-hanging mounting, crimp termination, and -55°C to 200°C operating range.

Compliance Considerations: Both parts are RoHS non-compliant and carry identical ECCN (EAR99) classification, ensuring regulatory consistency in applications requiring military, aviation, or automotive deployment. Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Structural Differences: The PV76W18-11PL is specified as a plug housing for male pins with a coupling nut feature, whereas the AFD56-18-11PN is a complete plug assembly with integrated male pins. The PV76W18-11PL requires separate contact procurement and assembly. Shell finish differs (chromate over cadmium on PV76W18-11PL versus nickel on AFD56-18-11PN) and housing color is olive drab on the substitute versus silver on the original. These differences do not affect electrical or mechanical interchangeability in applications where the connector housing and fastening interface are the primary functional requirements.

Frequently Asked Questions (FAQ)

Q: Can the PV76W18-11PL directly replace the AFD56-18-11PN in existing assemblies?

A: The PV76W18-11PL matches all critical mechanical and electrical parameters required for substitution: 11 positions, 18-11 shell size, bayonet lock fastening, free-hanging mounting, and crimp termination. Both operate across -55°C to 200°C. However, the PV76W18-11PL is a plug housing that requires separate male pin contacts, whereas the AFD56-18-11PN is a complete plug assembly. Compatibility depends on whether your application requires a complete assembly or a housing-only component.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: number of positions (11), shell size (18-11), mounting type (free-hanging in-line), fastening type (bayonet lock), orientation (normal), operating temperature range (-55°C to 200°C), and termination method (crimp). All these parameters are identical between the AFD56-18-11PN and PV76W18-11PL.

Q: Why do the shell finishes differ between the main part and substitute?

A: The AFD56-18-11PN features nickel shell finish with gold contact mating finish, while the PV76W18-11PL uses chromate over cadmium shell finish. These finishes do not affect mechanical interchangeability or electrical performance in the connector interface. Selection between finishes depends on corrosion resistance requirements specific to your application environment.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS non-compliant and carry identical ECCN (EAR99) classification. Both maintain Moisture Sensitivity Level 1 (Unlimited). No compliance or certification differences exist that would restrict substitution in regulated applications.

Q: What is the contact size specification for the PV76W18-11PL?

A: The PV76W18-11PL specifies contact size 16. This parameter is provided for the substitute part but is not listed for the AFD56-18-11PN in the available data. Contact size 16 is standard for 11-position MIL-DTL-26482 connectors and is compatible with the AFD56-18-11PN's crimp termination specification.

Q: Does the PV76W18-11PL include contacts?

A: No. The PV76W18-11PL is specified as a plug housing with the note "Contacts Not Included." Male pin contacts must be procured separately and crimped into the housing. The AFD56-18-11PN is a complete plug assembly with integrated male pins.

Q: What applications are these connectors suitable for?

A: Both connectors are rated for aviation, automotive, and military applications. The environment-resistant ingress protection and -55°C to 200°C operating range support deployment in demanding thermal and environmental conditions typical of these industries.
