Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5222506-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: TNC
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded

Compatibility Considerations: The substitute part must maintain the same electrical impedance (50 Ohms) and termination method (crimp) to ensure signal integrity and mechanical compatibility. The TNC threaded interface and male pin configuration are non-negotiable for connector mating compatibility.

Allowable Variations: Substitute parts may exceed the original specifications in frequency rating, operating temperature range, and dielectric material composition, provided all mandatory parameters remain identical. Cable group compatibility may differ while maintaining 50-ohm impedance.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol SV Microwave M39012/26B0006 serves as a direct functional substitute for the obsolete TE Connectivity 5222506-1. Both connectors maintain identical core specifications: TNC male plug configuration, 50-ohm impedance, crimp termination for center contact and shield, threaded fastening, and free-hanging in-line mounting.

Product Status Advantage: The Amphenol M39012/26B0006 is classified as active, ensuring continued availability and manufacturing support. The TE Connectivity 5222506-1 obsolete status creates supply chain risk for new production and field replacements.

Compliance Status: Both parts meet RoHS requirements. The Amphenol part carries ROHS3 compliance and is REACH affected, indicating current regulatory alignment. The TE Connectivity part is RoHS compliant with undefined REACH status.

Performance Envelope: The Amphenol substitute exceeds the original specifications in frequency rating (11 GHz versus 7 GHz) and operating temperature range (-65°C ~ 165°C versus -55°C ~ 85°C). These enhancements provide design margin without compromising compatibility. The PTFE dielectric material in the Amphenol part offers superior high-frequency performance compared to the polypropylene dielectric in the original.

Cable Compatibility: The original part supports RG-58 series cables. The substitute supports RG-142 and RG-400 cables, both 50-ohm specifications suitable for TNC crimp applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol M39012/26B0006 directly replace the TE Connectivity 5222506-1 in existing assemblies?

A: Yes. Both connectors share identical TNC male plug configuration, 50-ohm impedance, crimp termination method, and threaded fastening. The mechanical and electrical interfaces are fully compatible.

Q: What is the significance of the different dielectric materials (PP versus PTFE)?

A: Polypropylene (PP) and polytetrafluoroethylene (PTFE) are both suitable dielectric materials for 50-ohm TNC connectors. PTFE offers superior performance at higher frequencies and wider temperature ranges. For applications operating within the original 7 GHz and -55°C ~ 85°C specifications, either material is functionally equivalent.

Q: Why does the Amphenol part support different cable groups (RG-142, RG-400 versus RG-58)?

A: Cable group designation reflects the specific cable types for which the connector is optimized. All referenced cable groups (RG-58, RG-142, RG-400) are 50-ohm coaxial specifications compatible with TNC crimp connectors. The substitute part's support for RG-142 and RG-400 does not preclude use with RG-58 cables; it indicates the connector design accommodates a broader range of 50-ohm cable diameters.

Q: What is the impact of the higher frequency rating (11 GHz versus 7 GHz) on system design?

A: The higher frequency rating of the Amphenol part indicates superior performance capability at elevated frequencies. For systems operating at or below 7 GHz, this specification difference has no impact. For future designs or systems requiring operation above 7 GHz, the Amphenol part provides additional design margin.

Q: Are there any packaging differences between these parts?

A: The TE Connectivity part includes 3 pieces per package (1 connector, 1 contact, 1 ferrule). The Amphenol part is supplied in bulk packaging. Procurement quantities and assembly processes should account for this packaging difference.

Q: How do the operating temperature ranges affect component selection?

A: The TE Connectivity part operates from -55°C to 85°C. The Amphenol substitute operates from -65°C to 165°C. For applications within the original temperature range, both parts are suitable. For systems requiring extended temperature operation, the Amphenol part provides additional capability.

Q: Is the difference in body finish (Nickel versus Silver) significant for RF performance?

A: Both nickel and silver finishes on brass bodies provide adequate corrosion resistance and electrical conductivity for TNC connector applications. The finish difference does not affect RF performance or mechanical compatibility. Selection between these finishes is determined by environmental exposure and corrosion resistance requirements specific to the application.
