Amphenol RF 112706 BNC Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 112706 is an active BNC connector jack designed for RF coaxial applications requiring 50 ohm impedance. This female socket connector features right-angle panel mount configuration with through-hole solder termination and bulkhead mounting capability. The connector is rated for 4 GHz maximum frequency and 500 mating cycles, making it suitable for PCB-integrated RF signal transmission in industrial and telecommunications equipment. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component flexibility.

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 112706 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Mounting Type: Panel Mount, Through Hole, Right Angle
• Contact Termination: Solder
• Shield Termination: Solder
• Frequency - Max: 4 GHz
• Voltage Rating: 500 V
• Fastening Type: Bayonet Lock
• Body Material: Zinc Die Cast
• Body Finish: Nickel
• Center Contact Plating: Gold
• Dielectric Material: Polypropylene (PP)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Affected

The Amphenol RF 112487 meets all mandatory matching parameters and qualifies as a parametric equivalent substitute for the 112706. Both connectors maintain identical electrical and mechanical specifications across RF performance, termination methods, and environmental compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 112706 and Amphenol RF 112487 are active products with identical compliance certifications (ROHS3 Compliant, REACH Affected). Selection between these parts is based on the following engineering considerations:

Primary Part (112706): Current inventory of 881 pieces. Beryllium copper center contact material. Two-port configuration. Suitable for applications where beryllium copper contact properties are specified or preferred.

Substitute Part (112487): Higher inventory availability of 1550 pieces. Phosphor bronze center contact material. Single-port configuration. Documented insertion loss specification of 0.2 dB. Suitable for applications where phosphor bronze contact material is acceptable and insertion loss documentation is required.

Both connectors maintain identical electrical performance at 50 ohms impedance, 4 GHz maximum frequency, and 500 volt rating. The center contact material difference (beryllium copper versus phosphor bronze) represents the primary technical distinction. Both materials are established contact materials in RF connector applications and provide equivalent performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112487 be used as a direct replacement for the 112706 in existing PCB designs?

A: The 112487 is electrically and mechanically equivalent to the 112706 across all critical RF and mechanical parameters. Both connectors feature identical 50 ohm impedance, 4 GHz frequency rating, right-angle panel mount through-hole configuration, and solder termination. The primary difference is the center contact material (phosphor bronze versus beryllium copper) and port count (1 versus 2). PCB footprints and mounting hole patterns are identical, allowing direct substitution in board layouts.

Q: What is the significance of the different center contact materials?

A: The 112706 uses beryllium copper center contacts, while the 112487 uses phosphor bronze. Both materials are standard in RF connector applications and provide equivalent electrical performance within the specified 50 ohm, 4 GHz operating range. Material selection is typically driven by application-specific requirements such as contact wear resistance, spring force characteristics, or material availability. Either material is suitable for standard RF signal transmission applications.

Q: Why do the part numbers show different port counts (2 versus 1)?

A: The port count specification reflects the connector configuration. The 112706 is specified with 2 ports, while the 112487 is specified with 1 port. Both are single BNC jack connectors with identical mechanical and electrical interfaces. This difference in port count designation does not affect substitution eligibility or functional compatibility in applications requiring a single BNC jack connector.

Q: Is insertion loss a critical factor in selecting between these connectors?

A: The 112487 specifies insertion loss of 0.2 dB, while the 112706 does not provide an insertion loss specification. For applications where insertion loss documentation is required for compliance or performance verification, the 112487 provides this specification. Both connectors operate at identical impedance and frequency ratings, and the specified 0.2 dB insertion loss for the 112487 is typical for BNC connectors in this class.

Q: Are both connectors RoHS and REACH compliant?

A: Both the Amphenol RF 112706 and 112487 are ROHS3 Compliant and REACH Affected. Both connectors meet current environmental and regulatory compliance requirements for electronic components in industrial and commercial applications.

Q: What is the difference in inventory availability?

A: The 112706 has 881 pieces in stock, while the 112487 has 1550 pieces in stock. Higher inventory availability of the 112487 may provide supply chain advantages for applications requiring larger quantities or extended delivery schedules.
