Substitute Part Grouping Explanation

Substitution of the Greenlee Communications 9512 is based on the following critical parameters:

Primary Compatibility Criteria:

• Connector style must be BNC
• Connector type must be Plug, Male Pin
• Shield termination must be Crimp
• Fastening type must be Bayonet Lock
• Cable group compatibility must include RG-58 and 141

Secondary Compatibility Criteria:

• Active product status for ongoing availability
• RoHS compliance certification
• Equivalent ECCN and HTSUS classifications

The Amphenol RF 31-320-RFX satisfies all primary and secondary criteria, with extended cable group support and active manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 31-320-RFX (part number 31-320-RFX) is the direct equivalent for the obsolete Greenlee Communications 9512. Selection is based on:

Product Status: The 31-320-RFX maintains active manufacturing status, ensuring long-term procurement availability and supply chain continuity.

Compliance Certification: Both parts carry equivalent export classifications (EAR99) and harmonized tariff codes (8536.69.4010). The 31-320-RFX meets ROHS3 compliance, exceeding the RoHS Compliant status of the original part.

Functional Equivalence: The 31-320-RFX supports all cable groups specified for the 9512 (RG-58, 141, 142) with additional compatibility for RG-58A, 58B, 58C, 303, LMR-195, Belden B7806A, and 9907 cables.

Termination Compatibility: Both connectors employ crimp shield termination and bayonet-lock fastening, ensuring mechanical and electrical compatibility in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 31-320-RFX directly replace the Greenlee 9512 in existing assemblies?

A: Yes. Both connectors share identical connector style (BNC), type (Plug, Male Pin), shield termination method (Crimp), and fastening mechanism (Bayonet Lock). The 31-320-RFX supports all cable groups specified for the 9512.

Q: What is the impedance specification for the Amphenol RF 31-320-RFX?

A: The 31-320-RFX is rated at 50 Ohms, consistent with standard BNC connector impedance specifications for RF applications.

Q: Are there packaging differences between the two parts?

A: The Greenlee 9512 packaging specification is not provided in the original documentation. The Amphenol RF 31-320-RFX is supplied in Bulk packaging and includes 3 pieces per connector: 1 Connector, 1 Contact, and 1 Ferrule.

Q: What is the maximum operating frequency of the substitute part?

A: The Amphenol RF 31-320-RFX operates to a maximum frequency of 4 GHz, suitable for standard RF and coaxial cable applications.

Q: Does the substitute part support both crimp and solder termination?

A: The 31-320-RFX contact termination supports both Crimp or Solder methods, providing flexibility beyond the crimp-only specification of the original 9512.

Q: What is the mating cycle rating for the Amphenol RF 31-320-RFX?

A: The 31-320-RFX is rated for 500 mating cycles, indicating durability for repeated connection and disconnection operations.
