Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 456-107 is constrained by the following critical parameters:

Connector Interface Requirements: The substitute must maintain BNC connector style with female socket (jack) configuration to ensure mechanical and electrical compatibility with existing mating connectors.

Termination Method: Solder termination is required for direct replacement in applications utilizing solder-based assembly processes.

Mounting Configuration: Panel mount, right angle orientation is essential for applications where the connector must be mounted perpendicular to the circuit board or panel surface.

Fastening Mechanism: Bayonet lock fastening must be preserved to maintain compatibility with standard BNC cable assemblies.

Impedance Consideration: The 75 Ohms impedance specification is application-specific. Substitutes with different impedance values (such as 50 Ohms) represent functional alternatives only for systems where impedance matching can be accommodated or where the application permits impedance variation.

Electrical and Environmental Ratings: Operating temperature range, mating cycle rating, and voltage rating establish minimum performance thresholds for substitute selection.

Compliance Status: Active product status with current RoHS certification ensures long-term availability and regulatory compliance.

Engineering Selection Recommendations

Primary Substitute: Molex 0731000166

The Molex 0731000166 serves as a functional equivalent for the obsolete Amphenol ICC 456-107 based on the following engineering criteria:

Mechanical Compatibility: Both connectors employ BNC female socket configuration with bayonet lock fastening, ensuring compatibility with standard BNC male connectors and cable assemblies. The right angle panel mount orientation is preserved in both designs.

Electrical Interface: Solder termination for both center contact and shield is maintained, supporting direct integration into existing PCB assembly processes. Gold-plated phosphor bronze center contacts in both connectors provide equivalent contact reliability and signal integrity.

Regulatory Compliance: The Molex 0731000166 maintains active product status with ROHS3 compliance, ensuring continued availability and adherence to current environmental regulations. The Amphenol ICC 456-107, classified as obsolete, presents supply chain risk and potential regulatory obsolescence.

Performance Ratings: Both connectors specify 500 mating cycles, establishing equivalent mechanical durability for typical application environments.

Critical Difference - Impedance: The Molex 0731000166 operates at 50 Ohms impedance, compared to the 75 Ohms specification of the Amphenol ICC 456-107. This impedance difference is application-dependent. Substitution is appropriate for systems designed to accommodate 50 Ohms impedance or where impedance matching networks are implemented. For applications requiring strict 75 Ohms impedance matching without compensation, alternative 75 Ohms BNC connectors must be evaluated.

Mounting Variation: The Molex 0731000166 incorporates through-hole mounting capability in addition to panel mount configuration, providing enhanced mechanical stability in PCB assembly applications compared to the rear-side nut mounting of the Amphenol ICC 456-107.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0731000166 directly replace the Amphenol ICC 456-107 in all applications?

A: Direct replacement is possible for mechanical and electrical interface compatibility. The primary consideration is impedance: the Molex part operates at 50 Ohms versus the original 75 Ohms specification. Substitution is appropriate where the system design accommodates 50 Ohms impedance or where impedance matching is implemented. For applications requiring uncompensated 75 Ohms impedance, alternative suppliers must be consulted.

Q: What are the key mechanical compatibility factors?

A: Both connectors share BNC female socket configuration, bayonet lock fastening, right angle panel mount orientation, and solder termination. These parameters ensure mechanical interchangeability with standard BNC male connectors and existing cable assemblies.

Q: Why is the Amphenol ICC 456-107 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. This classification necessitates identification of active alternatives to ensure supply chain continuity and regulatory compliance for ongoing system support.

Q: Does the Molex 0731000166 offer any advantages over the original part?

A: The Molex 0731000166 provides active product status with current ROHS3 compliance, ensuring long-term availability and regulatory alignment. The through-hole mounting option provides enhanced mechanical stability in PCB assembly compared to rear-side nut mounting.

Q: Are there packaging differences between these connectors?

A: The Amphenol ICC 456-107 includes mounting hardware (lockwasher and nut) in the package. The Molex 0731000166 is supplied in bag packaging without additional hardware. Assembly requirements should be evaluated based on specific application needs.

Q: What is the significance of the 50 Ohms versus 75 Ohms impedance difference?

A: Impedance specification determines signal transmission characteristics in RF applications. 75 Ohms is standard for video and certain RF applications, while 50 Ohms is standard for general RF and microwave applications. Substitution requires confirmation that the system design accommodates the 50 Ohms impedance or that impedance matching is implemented.

Q: Are the electrical performance ratings equivalent?

A: Both connectors specify 500 mating cycles and equivalent contact materials (phosphor bronze with gold plating). Operating temperature ranges and voltage ratings are comparable, establishing equivalent electrical performance for standard applications.
