Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 112332 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Clamp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Frequency - Max: 4 GHz
• Voltage Rating: 500 V
• Insertion Loss: 0.2 dB
• Cable Group Compatibility: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907

Both substitute parts (31-2-RFX and 031-3202) meet all mandatory matching parameters. Variations in secondary parameters such as dielectric material, center contact plating, operating temperature specification, and packaging do not affect functional substitution for the specified cable groups and frequency range.

Parameter Comparison

Engineering Selection Recommendations

Part 31-2-RFX is the primary substitute for the Amphenol RF 112332. This part carries Active product status, indicating ongoing manufacturer support and availability. It maintains full electrical and mechanical equivalence across all critical parameters. The 31-2-RFX is supplied in bulk packaging and has higher inventory availability (2070 units). This part is suitable for new installations and ongoing production requirements.

Part 031-3202 is a secondary parametric equivalent. While it meets all mandatory electrical and mechanical specifications, it incorporates PTFE dielectric material and silver center contact plating, differing from the main part's polyoxymethylene dielectric and gold plating. The 031-3202 also carries Active product status and is REACH Affected. This part is suitable for applications where the specified dielectric and plating materials are acceptable.

Both substitute parts are ROHS3 compliant and carry identical compliance certifications (ECCN EAR99, HTSUS 8536.69.4010). Selection between 31-2-RFX and 031-3202 should be based on material specifications required by the application and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 31-2-RFX directly replace the 112332 in existing installations?

A: Yes. The 31-2-RFX meets all mandatory electrical and mechanical parameters: BNC connector style, 50-ohm impedance, solder termination, 4 GHz frequency rating, 500 V voltage rating, and compatibility with the specified cable groups (RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907). Mechanical fit and electrical performance are equivalent.

Q: What is the difference between the 31-2-RFX and 031-3202?

A: Both parts are electrically and mechanically equivalent for the specified application. The 031-3202 differs in dielectric material (PTFE versus polyoxymethylene) and center contact plating (silver versus gold). These material differences do not affect substitution for the specified cable groups and frequency range but may be relevant for specific environmental or performance requirements.

Q: Why is the 112332 marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product line. The 31-2-RFX and 031-3202 are active alternatives. For new designs, selection should prioritize parts with Active product status.

Q: Are there packaging differences between these parts?

A: Yes. The 112332 is supplied in bag packaging, while both 31-2-RFX and 031-3202 are supplied in bulk packaging. Packaging does not affect connector functionality but may influence procurement and handling procedures.

Q: Do all three parts support the same cable types?

A: Yes. All three parts are compatible with RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cable groups.

Q: Are there operating temperature differences?

A: The 112332 does not specify an operating temperature range. Both 31-2-RFX and 031-3202 specify -65°C to 165°C operating temperature. This specification does not affect substitution but provides additional environmental performance data for the active alternatives.

Q: What is the mating cycle rating for these connectors?

A: All three parts are rated for 500 mating cycles.
