AFD51-22-55PN Equivalent & Substitute Parts

Part Overview

The AFD51-22-55PN is a 55-position circular connector receptacle manufactured by TE Connectivity Deutsch Connectors. This connector features male pins with crimp termination, bayonet lock fastening, and is designed for applications in aviation, automotive, and military environments. The connector operates across a temperature range of -55°C to 200°C and carries a current rating of 7.5A.

This part is discontinued at DiGi Electronics, making identification of equivalent and substitute components essential for ongoing system maintenance, repair, and new design implementations. The connector's specific configuration—55 positions with gold-plated mating contacts and nickel-finished aluminum shell—defines the substitution criteria for compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AFD51-22-55PN is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector category: Circular Connectors
• Number of positions: 55
• Shell size designation: 22-55
• Connector type: Receptacle with male pins
• Termination method: Crimp
• Fastening mechanism: Bayonet lock
• Contact finish: Gold plating on mating surfaces
• Current capacity: 7.5A minimum
• Operating temperature range: -55°C to 200°C minimum
• Environmental resistance classification
• RoHS compliance status: Non-compliant (matching legacy military/aerospace applications)
• Regulatory classification: EAR99 and HTSUS 8536.69.4020

The substitute part PV71W22-55P, manufactured by ITT Cannon, LLC, is identified as functionally equivalent based on shared category classification and regulatory coding. Both components are designated for circular connector applications within the same tariff and export control classifications, indicating compatibility within the same application domain.

Parameter Comparison

Engineering Selection Recommendations

For Discontinued Part Replacement:

The AFD51-22-55PN is discontinued at DiGi Electronics. The PV71W22-55P from ITT Cannon, LLC is classified as an active substitute based on matching regulatory classifications (EAR99, HTSUS 8536.69.4020), identical RoHS non-compliance status, and shared MSL rating of 1 (Unlimited). Both components are designated for circular connector applications and maintain equivalent environmental and regulatory profiles.

Compliance Considerations:

Both the original AFD51-22-55PN and substitute PV71W22-55P are RoHS non-compliant, which is consistent with military and aerospace-grade connector specifications. This non-compliance status is intentional for applications requiring extended operating temperature ranges and specialized material compositions. The matching ECCN and HTSUS classifications confirm regulatory equivalence for export and tariff purposes.

Inventory and Availability:

The AFD51-22-55PN maintains 1066 pieces in new original stock, while the PV71W22-55P substitute has 807 pieces available. Both components are currently in stock, providing options for immediate procurement.

Selection Basis:

Component selection should be based on application requirements for the 55-position circular connector configuration, crimp termination compatibility with existing harness assemblies, and bayonet lock fastening requirements. The matching regulatory classifications and RoHS status ensure that either component meets the same compliance framework for the intended application domain.

Frequently Asked Questions (FAQ)

Q: What makes PV71W22-55P a valid substitute for AFD51-22-55PN?

A: Both components are classified as circular connectors with matching regulatory designations (EAR99, HTSUS 8536.69.4020), identical RoHS non-compliance status, and equivalent MSL ratings. The substitute is manufactured by ITT Cannon, LLC and maintains active product status, addressing the discontinuation of the original TE Connectivity part.

Q: Are there mechanical compatibility concerns when substituting AFD51-22-55PN with PV71W22-55P?

A: Mechanical compatibility depends on the specific connector configuration parameters. The provided data confirms both components are 55-position circular connectors with shell size designation 22-55. Physical verification of mating interface geometry, pin arrangement, and fastening mechanism alignment is required before implementation in existing assemblies.

Q: Does the substitute part meet the same environmental specifications?

A: Both components are classified as RoHS non-compliant with MSL rating 1 (Unlimited), indicating equivalent environmental handling and storage requirements. The matching regulatory classifications confirm alignment with the same compliance framework for military and aerospace applications.

Q: What is the significance of the matching HTSUS and ECCN codes?

A: The identical HTSUS code (8536.69.4020) and ECCN classification (EAR99) indicate that both components fall under the same tariff classification and export control category. This ensures regulatory equivalence for procurement, import, and export purposes.

Q: Can I use PV71W22-55P as a direct replacement in existing designs?

A: The substitute part shares the same category, regulatory classification, and environmental rating as the original AFD51-22-55PN. However, detailed verification of connector pin configuration, contact arrangement, and mating interface specifications is necessary to confirm direct interchangeability in specific circuit designs and harness assemblies.

Q: What is the difference in packaging between the two parts?

A: The AFD51-22-55PN packaging specification is not provided in the available data. The PV71W22-55P is supplied in bulk packaging. Packaging differences may affect handling, storage, and integration into assembly processes but do not impact functional compatibility.

Q: Are both parts currently available for procurement?

A: Yes. The AFD51-22-55PN has 1066 pieces in new original stock, while the PV71W22-55P substitute has 807 pieces available. Both components are in stock for immediate procurement.
