TE Connectivity AMP Connectors 413760-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 413760-8 is a BNC Connector Jack with female socket configuration, rated at 75 Ohms impedance for coaxial RF applications. This free-hanging (in-line) connector features crimp termination for both center contact and shield, with a maximum frequency rating of 2 GHz. The part is currently active in production with 1082 pieces in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, allowing for alternative sourcing while preserving circuit performance and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 413760-8 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Connector Style: BNC (bayonet lock mechanism)
• Connector Type: Jack, Female Socket (mating interface)
• Impedance: 75 Ohms (signal integrity)
• Voltage Rating: 500 V (electrical stress tolerance)
• Frequency - Max: 2 GHz or higher (bandwidth capability)

Mechanical Compatibility Requirements:

• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Number of Ports: 1
• Cable Group: RG-179, 179A, 179B, 187, 187A (or compatible subset)

Termination Compatibility: The main part specifies crimp termination for both center contact and shield. Substitute parts with alternative termination methods (such as solder) are functionally equivalent when the connector interface, impedance, and mechanical mounting remain identical, as the termination method affects only the assembly process, not the mating interface or electrical performance.

The identified substitute part 031-71014-RFX from Amphenol RF meets all electrical and mechanical compatibility criteria while offering an alternative termination approach.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 413760-8 Selection Criteria:

• Applications requiring crimp termination assembly methods
• Systems operating across the full temperature range of -55°C to 85°C
• Designs where RoHS non-compliance is acceptable or required by specification
• Existing supply chain or inventory management requirements

Amphenol RF 031-71014-RFX Selection Criteria:

• Applications utilizing solder termination assembly methods
• Systems operating within the -40°C to 80°C temperature range
• Designs requiring ROHS3 compliance certification
• Applications supporting extended cable group compatibility (Belden 9221, M17/94-RG179)
• Designs where REACH compliance is required

Compatibility Considerations: Both parts maintain identical BNC jack female socket configuration with 75 Ohm impedance and bayonet lock fastening. The primary differences are termination method (crimp versus solder), material composition, and regulatory compliance status. Operating temperature range differs by 15°C at the lower limit and 5°C at the upper limit for the Amphenol part. Insertion loss specification shows 0.05 dB difference, with the TE Connectivity part exhibiting lower insertion loss.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 031-71014-RFX directly replace the TE Connectivity 413760-8 in existing assemblies?

A: Direct mechanical and electrical replacement is possible for the mating interface. However, the termination method differs (solder versus crimp), requiring assembly process modification. The operating temperature range is narrower for the Amphenol part (-40°C to 80°C versus -55°C to 85°C), which may restrict use in extreme temperature applications.

Q: What is the significance of the different contact materials (Beryllium Copper versus Phosphor Bronze)?

A: Both materials provide acceptable electrical conductivity and contact reliability for 75 Ohm BNC connectors. Material selection affects mechanical properties and manufacturing processes but does not alter the electrical interface or mating compatibility.

Q: Does the difference in insertion loss (0.15 dB versus 0.2 dB) affect system performance?

A: The 0.05 dB difference is within typical measurement tolerance for coaxial connectors at 2 GHz. System impact depends on total link budget and application requirements. Both values are acceptable for standard RF applications.

Q: Are the different dielectric materials (Polyethylene versus Polyoxymethylene Acetal) interchangeable?

A: Both materials function as insulators in the connector structure. Polyethylene and Polyoxymethylene Acetal have different moisture absorption and temperature stability characteristics, but both are suitable for 75 Ohm RF connectors. Selection depends on environmental exposure and long-term reliability requirements.

Q: What cable types are compatible with each connector?

A: Both connectors support RG-179, 179A, 179B, 187, and 187A cables. The Amphenol part additionally supports Belden 9221 and M17/94-RG179 cables, providing broader cable compatibility.

Q: How does RoHS compliance affect part selection?

A: The TE Connectivity 413760-8 is RoHS non-compliant, while the Amphenol RF 031-71014-RFX is ROHS3 compliant. Applications subject to RoHS regulations or customer requirements must use the compliant Amphenol part. Non-regulated applications may use either part based on other criteria.

Q: What is the difference between crimp and solder termination for this connector?

A: Crimp termination (TE Connectivity) uses mechanical compression to secure the cable conductor and shield. Solder termination (Amphenol) uses molten solder to create the electrical connection. Both methods achieve equivalent electrical performance when properly executed. Assembly method selection depends on manufacturing equipment and process capability.
