Amphenol RF 112714 BNC Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 112714 is a BNC connector jack (female socket) rated for 50 ohms impedance with panel mount bulkhead configuration and solder termination. This component is classified as Active product status with 887 pieces currently in stock. The need to identify equivalent and substitute parts arises from supply chain considerations, design flexibility, and component availability across different procurement channels. Substitute parts must maintain electrical compatibility through matching impedance, frequency rating, connector style, and termination method while accommodating mechanical variations in mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 112714 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Connector style must be BNC
• Connector type must be Jack, Female Socket
• Impedance must be 50 Ohms
• Fastening type must be Bayonet Lock
• Maximum frequency must be 4 GHz or greater
• Dielectric material must be Polytetrafluoroethylene (PTFE)

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount
• Termination method must be solder-based (Solder or Solder Cup acceptable)
• Body material must be Brass with Nickel finish
• Number of ports must be 1

Regulatory Compliance Requirements:

• RoHS3 Compliant status required
• REACH Affected status acceptable

The Hirose Electric Co Ltd UG-625/U-4(40) meets all electrical and mechanical compatibility criteria, with the exception of mounting feature configuration (Bulkhead - Rear Side Nut versus Bulkhead - Front Side Nut) and contact termination method variation (Solder Cup versus Solder). These differences do not prevent functional substitution in applications where rear-side mounting is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Amphenol RF 112714 (Primary Selection)

The Amphenol RF 112714 maintains Active product status, indicating ongoing manufacturer support and availability. This component is ROHS3 compliant and REACH affected, meeting current regulatory requirements. The part carries a 500 V voltage rating and 0.2 dB insertion loss specification. With 887 pieces in current inventory, supply continuity is established. The front-side bulkhead mounting configuration and direct solder termination provide straightforward PCB integration. This part is the preferred selection for new designs and applications requiring long-term component availability.

Hirose Electric Co Ltd UG-625/U-4(40) (Substitute Selection)

The Hirose UG-625/U-4(40) is classified as Last Time Buy, indicating limited future availability. This substitute maintains electrical compatibility through matching 50 ohm impedance, 4 GHz frequency rating, BNC connector style, and bayonet lock fastening. The component is ROHS3 compliant and REACH affected. The primary mechanical difference is rear-side bulkhead mounting versus front-side mounting on the primary part. The solder cup termination method differs from direct solder termination. The Hirose part demonstrates superior mating cycle rating (5000 cycles versus 500 cycles), indicating enhanced durability for high-cycle applications. This substitute is suitable for applications where rear-side mounting is mechanically acceptable and where extended mating cycle performance is beneficial. However, the Last Time Buy status restricts this part to existing designs or applications with established supply agreements.

Frequently Asked Questions (FAQ)

Q: Can the Hirose UG-625/U-4(40) directly replace the Amphenol RF 112714 in all applications?

A: Electrical substitution is valid. Both parts maintain 50 ohm impedance, 4 GHz frequency rating, BNC connector style, and bayonet lock fastening. The mechanical difference in mounting feature (rear-side versus front-side bulkhead) requires panel design verification. The solder cup termination method differs from direct solder termination, requiring PCB layout adjustment. Functional compatibility is confirmed; mechanical integration must be validated for specific panel configurations.

Q: What is the significance of the Last Time Buy status for the Hirose part?

A: Last Time Buy designation indicates the manufacturer has announced end-of-life for this component. Future availability is limited to existing inventory. New designs should not incorporate this part. Existing designs currently using this part should establish supply agreements or transition to alternative components. The Amphenol RF 112714 (Active status) is the recommended selection for new applications.

Q: Are there differences in contact material that affect performance?

A: The Amphenol RF 112714 uses Phosphor Bronze center contact with Gold plating. The Hirose UG-625/U-4(40) uses Beryllium Copper center contact with Silver plating. Both material combinations are suitable for 50 ohm RF applications at 4 GHz. Contact material selection does not prevent functional substitution. Material differences may affect contact resistance and long-term reliability characteristics; however, both combinations meet standard RF connector performance requirements.

Q: What is the practical difference between Solder and Solder Cup termination?

A: Solder termination requires direct solder connection to PCB pads. Solder Cup termination uses a cup-shaped contact that accepts wire or cable termination through solder. The Amphenol part (Solder) integrates directly to PCB traces. The Hirose part (Solder Cup) accommodates wire termination. Application requirements determine which termination method is appropriate. PCB-mounted applications require Solder termination; wire-terminated applications require Solder Cup termination.

Q: Why does the Hirose part have a higher mating cycle rating?

A: The Hirose UG-625/U-4(40) specifies 5000 mating cycles compared to 500 cycles for the Amphenol RF 112714. This difference reflects design and material selection choices by each manufacturer. Higher mating cycle ratings indicate enhanced durability for applications requiring frequent connector engagement and disengagement. Applications with low mating cycle requirements (under 500 cycles) are satisfied by either part. Applications exceeding 500 mating cycles benefit from the Hirose part's extended cycle rating.

Q: Are both parts compliant with current regulatory requirements?

A: Both the Amphenol RF 112714 and Hirose UG-625/U-4(40) are ROHS3 compliant and REACH affected. Current regulatory compliance is confirmed for both parts. No regulatory barriers prevent substitution from a compliance perspective.
