TE Connectivity AMP Connectors 222165-2 BNC Coaxial Adapter Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 222165-2 is a coaxial adapter connector designed to convert BNC plug (male pin) connections to BNC jack (female socket) connections. This right-angle, free-hanging adapter operates at 50 ohms impedance and utilizes bayonet lock fastening. The part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity AMP Connectors 222165-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter type: Plug to Jack
• Adapter series: BNC to BNC
• Center gender: Female to Male
• Impedance: 50 Ohms
• Style: Right Angle
• Mounting type: Free Hanging (In-Line), Right Angle
• Fastening type: Bayonet Lock
• Dielectric material: Polytetrafluoroethylene (PTFE)

Both identified substitute parts (Amphenol RF 31-9 and TE Connectivity AMP Connectors 5-1634526-1) satisfy all mandatory matching parameters. Variations in body material, center contact plating, and compliance certifications do not affect functional interchangeability within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

Primary Substitute: Amphenol RF 31-9

The Amphenol RF 31-9 is the preferred substitute for the obsolete TE Connectivity AMP Connectors 222165-2. This part maintains full electrical and mechanical compatibility across all critical parameters. The 31-9 holds active product status, ensuring continued availability and supply chain reliability. The part is ROHS3 compliant, meeting current environmental and regulatory standards. Specified operating temperature range (-65°C ~ 165°C) and maximum frequency (4 GHz) provide documented performance boundaries. Bulk packaging availability supports both prototype and production-level requirements.

Secondary Substitute: TE Connectivity AMP Connectors 5-1634526-1

The TE Connectivity AMP Connectors 5-1634526-1 provides functional equivalence and maintains the same manufacturer ecosystem. This part is RoHS compliant and shares identical adapter geometry and fastening characteristics. However, the dielectric material differs (polyethylene versus polytetrafluoroethylene), which may affect high-frequency performance characteristics. The part is classified as obsolete, limiting long-term supply assurance. This substitute is suitable for legacy system maintenance where original manufacturer continuity is prioritized.

Compliance Considerations

The original 222165-2 is RoHS non-compliant. Both substitute parts address this compliance gap: the Amphenol RF 31-9 achieves ROHS3 compliance, while the TE Connectivity 5-1634526-1 achieves RoHS compliance. Selection should align with applicable regulatory requirements for the target application and market.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 31-9 directly replace the TE Connectivity AMP Connectors 222165-2 in existing installations?

A: Yes. Both parts are BNC plug-to-jack adapters with identical 50-ohm impedance, right-angle configuration, bayonet lock fastening, and PTFE dielectric material. The electrical and mechanical interfaces are fully compatible.

Q: What is the significance of the dielectric material difference between 222165-2 and 5-1634526-1?

A: The original 222165-2 uses polytetrafluoroethylene (PTFE) dielectric, while the 5-1634526-1 uses polyethylene (PE). PTFE provides superior high-frequency performance and lower dielectric loss. For applications operating above 1 GHz, the PTFE-based Amphenol RF 31-9 is the preferred selection.

Q: Does the center contact plating material affect substitution compatibility?

A: Center contact plating (gold, silver, or combinations thereof) does not affect functional interchangeability. All three parts maintain beryllium copper or equivalent contact materials with appropriate plating for corrosion resistance and electrical conductivity.

Q: Why is the Amphenol RF 31-9 recommended over the TE Connectivity 5-1634526-1?

A: The Amphenol RF 31-9 holds active product status, ensuring ongoing availability and supply chain continuity. The 5-1634526-1 is obsolete, presenting potential future sourcing challenges. Additionally, the 31-9 provides documented operating temperature range and maximum frequency specifications.

Q: Are there packaging differences between the substitute parts?

A: The Amphenol RF 31-9 is available in bulk packaging. The original 222165-2 and TE Connectivity 5-1634526-1 packaging specifications are not detailed in the provided data. Bulk packaging from the 31-9 supports both small-quantity and production-volume requirements.

Q: What is the moisture sensitivity level for these adapters?

A: All three parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints. These components do not require special moisture-controlled storage or handling procedures.

Q: How do the RoHS compliance statuses affect part selection?

A: The original 222165-2 is RoHS non-compliant. For applications subject to RoHS regulations (EU and equivalent markets), the Amphenol RF 31-9 (ROHS3 compliant) or TE Connectivity 5-1634526-1 (RoHS compliant) must be selected. For legacy or non-regulated applications, the original part remains functionally viable.
