Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 112652 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Front Side Nut
• Fastening Type: Bayonet Lock
• Frequency - Max: 4 GHz
• Voltage Rating: 500 V
• Mating Cycles: 500
• Number of Ports: 1

The TE Connectivity Aerospace, Defense and Marine part number 6-331693-2 meets all mandatory matching parameters and qualifies as a direct substitute. Both parts are ROHS3 compliant and REACH affected, ensuring regulatory alignment. Differences in cable group compatibility, dielectric material, body finish, and center contact material do not preclude substitution when the core electrical and mechanical specifications are identical.

The TE Connectivity part is ROHS3 compliant and REACH affected, ensuring regulatory compliance. However, this part is discontinued at DiGi Electronics, which may affect long-term availability. The TE Connectivity part is suitable for substitution in applications where the Amphenol RF 112652 is unavailable, provided that inventory can be sourced through alternative distribution channels.

Regulatory and Compliance Alignment

Both parts are ROHS3 compliant and REACH affected, confirming suitability for regulated markets and applications requiring environmental compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-331693-2 be used as a direct replacement for the Amphenol RF 112652?

A: Yes. Both parts are BNC jack connectors with identical 50-ohm impedance, crimp termination, panel-mount bulkhead configuration, bayonet fastening, 4 GHz frequency rating, 500-volt rating, and 500 mating cycle specification. The parts are electrically and mechanically equivalent for applications within these parameters.

Q: What are the differences between these two parts?

A: The parts differ in body finish (Amphenol RF uses nickel; TE Connectivity uses silver), center contact material (Amphenol RF uses phosphor bronze; TE Connectivity uses beryllium copper), dielectric material (Amphenol RF uses polyoxymethylene acetal; TE Connectivity uses polytetrafluoroethylene), and compatible cable groups. The Amphenol RF part supports RG-55, 142, 223, and 400 cables, while the TE Connectivity part supports RG-174 and 188 cables. These differences do not affect substitution eligibility when the core electrical and mechanical specifications match.

Q: Why is the TE Connectivity part listed as discontinued?

A: The TE Connectivity 6-331693-2 is discontinued at DiGi Electronics, indicating that this distributor no longer carries the part. However, discontinuation at a single distributor does not mean the part is unavailable from all sources. Alternative distribution channels may still stock this component.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the Amphenol RF 112652 and TE Connectivity 6-331693-2 are ROHS3 compliant and REACH affected, meeting current environmental and hazardous substance regulations.

Q: What cable types are compatible with each connector?

A: The Amphenol RF 112652 is compatible with RG-55, 142, 223, and 400 coaxial cables. The TE Connectivity 6-331693-2 is compatible with RG-174 and 188 coaxial cables. Cable selection depends on application impedance and frequency requirements. Verify cable compatibility with your specific application before final component selection.

Q: What is the operating temperature range for these connectors?

A: The Amphenol RF 112652 does not specify an operating temperature range in the provided data. The TE Connectivity 6-331693-2 operates from -55°C to 85°C. For applications requiring specific temperature performance, consult the detailed technical specifications from each manufacturer.

Q: How many mating cycles are these connectors rated for?

A: Both connectors are rated for 500 mating cycles, indicating the expected number of connect/disconnect operations before performance degradation.
