Amphenol RF 112615 BNC Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 112615 is a BNC connector jack (female socket) rated for 50 ohms impedance, designed for free-hanging in-line solder termination applications. This component operates at frequencies up to 4 GHz and is suitable for semi-rigid coaxial cable assemblies in the RG-405 cable group. The part is currently active in production with 892 units in stock.

Substitute parts are necessary when the original component becomes unavailable, when alternative termination methods (such as crimp) are preferred for manufacturing processes, or when compatibility with different cable groups is required while maintaining electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 112615 is determined by the following core parameters that must remain constant across all equivalent parts:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Frequency - Max: 4 GHz
• Number of Ports: 1
• Voltage Rating: 500 V
• Mating Cycles: 500
• Insertion Loss: 0.2 dB

Variable Parameters (Allowed to Differ):

• Contact Termination: Solder (main part) vs. Crimp (substitutes)
• Cable Group: RG-405 (main part) vs. RG-58/59 series (substitutes)
• Body Material: Brass (main part) vs. Zinc (substitute 5228979-6)
• Body Finish: Nickel or Silver
• Center Contact Material: Phosphor Bronze vs. Beryllium Copper
• Dielectric Material: PTFE vs. Polypropylene

The three identified substitute parts maintain electrical performance and mechanical compatibility while offering alternative termination methods and cable group compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: Amphenol RF 112615

The Amphenol RF 112615 remains the preferred component for applications requiring solder termination with RG-405 semi-rigid cable compatibility. The part is active in production with adequate inventory (892 units) and maintains ROHS3 compliance. Selection of this part is appropriate when solder termination is specified in the design and RG-405 cable group compatibility is required.

Secondary Selection: TE Connectivity 5228979-6

The TE Connectivity 5228979-6 is the recommended substitute when crimp termination is acceptable or preferred. This part is currently active in production with the highest inventory level (1235 units) and maintains ROHS3 compliance. The primary difference is the crimp termination method and compatibility with RG-59/62 cable groups instead of RG-405. Electrical performance (impedance, frequency, insertion loss, voltage rating, mating cycles) is identical to the main part. The dielectric material differs (polypropylene vs. PTFE), which does not affect the specified electrical parameters.

Tertiary Selection: TE Connectivity 2-331351-1

The TE Connectivity 2-331351-1 is available as an alternative substitute with crimp termination and RG-58 cable group compatibility. This part is discontinued at DiGi Electronics but maintains ROHS3 compliance and adequate inventory (1014 units). Selection of this part is appropriate only when RG-58 cable group compatibility is specifically required and crimp termination is acceptable.

Not Recommended: TE Connectivity 5225396-1

The TE Connectivity 5225396-1 is marked as obsolete and should not be selected for new designs or production applications. While it maintains RoHS compliance and adequate inventory (801 units), the obsolete status indicates discontinued manufacturer support and potential future unavailability.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112615 (solder termination) be directly replaced with a crimp termination substitute?

A: Direct mechanical replacement is possible due to identical connector geometry, bayonet lock fastening, and mounting type. However, the termination method differs fundamentally. Solder termination requires soldering equipment and processes, while crimp termination requires crimping tools and dies. Cable preparation and assembly procedures differ between these methods. Selection depends on manufacturing process capability and design requirements.

Q: What is the significance of the cable group difference between the main part and substitutes?

A: The cable group designation indicates the outer diameter and impedance compatibility of the coaxial cable. The main part (112615) is designed for RG-405 semi-rigid cable (.085" to .086" diameter). Substitutes are designed for RG-58 or RG-59 flexible cable groups with different diameters. While the connector electrical specifications remain identical, the physical cable interface differs. Selection must match the cable type specified in the application.

Q: Are the dielectric material differences (PTFE vs. Polypropylene) significant for substitution?

A: Both PTFE and polypropylene are acceptable dielectric materials for 50-ohm RF connectors operating at frequencies up to 4 GHz. The specified electrical parameters (impedance, insertion loss, voltage rating) are maintained with either material. The choice between materials affects cost, temperature stability, and moisture absorption characteristics, but does not impact the core electrical performance at the specified operating conditions.

Q: Why is TE Connectivity 5228979-6 recommended over 2-331351-1 despite both being crimp termination alternatives?

A: The TE Connectivity 5228979-6 is recommended because it maintains active product status with ongoing manufacturer support, while 2-331351-1 is discontinued at DiGi Electronics. Additionally, 5228979-6 has higher inventory availability (1235 units vs. 1014 units) and maintains ROHS3 compliance. Both parts meet the electrical specifications, but 5228979-6 offers superior supply chain reliability and long-term availability.

Q: Can the Amphenol RF 112615 be used in applications originally designed for RG-58 or RG-59 cables?

A: No. The Amphenol RF 112615 is specifically designed for RG-405 semi-rigid cable and is not compatible with flexible RG-58 or RG-59 cables due to physical diameter and termination interface differences. Conversely, substitutes designed for RG-58 or RG-59 are not compatible with RG-405 semi-rigid cable. Cable group compatibility must be maintained for proper mechanical and electrical performance.

Q: What is the significance of the product status designations (Active, Discontinued, Obsolete)?

A: Product status indicates manufacturer support and supply chain availability. Active parts have ongoing production and manufacturer support. Discontinued parts are no longer produced but may have existing inventory. Obsolete parts have reached end-of-life with no manufacturer support or future availability. For new designs and long-term production, active parts are preferred. Discontinued or obsolete parts should only be used when existing inventory is available and supply chain risk is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: The Amphenol RF 112615 and TE Connectivity 5228979-6 are ROHS3 compliant. The TE Connectivity 2-331351-1 is ROHS3 compliant. The TE Connectivity 5225396-1 is RoHS compliant but not specifically designated as ROHS3. For applications requiring ROHS3 compliance, the 5225396-1 should not be selected. Compliance verification with specific regulatory requirements is necessary before final part selection.
