Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 456-717 is determined by the following critical parameters:

Mechanical Compatibility:

• Connector style (BNC) and type (Jack, Female Socket) must remain identical
• Mounting configuration (Panel Mount, Through Hole, Right Angle) must match
• Fastening mechanism (Bayonet Lock) must be preserved
• Solder termination for both contact and shield must be maintained

Electrical Compatibility:

• Impedance specification is the primary electrical differentiator
• Voltage rating and mating cycle specifications must meet or exceed original requirements
• Operating temperature range must accommodate application requirements

Regulatory Compliance:

• RoHS compliance status must be verified for the application environment
• REACH status consideration for European market applications

The Molex 0731000223 is identified as a substitute part based on matching mechanical form factor and mounting characteristics. However, the impedance specification differs (50 Ohms versus 75 Ohms), which represents a critical electrical parameter variance requiring application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Impedance Specification

The Amphenol ICC 456-717 operates at 75 Ohms impedance, while the Molex 0731000223 operates at 50 Ohms impedance. This represents a fundamental electrical parameter difference. Selection of the Molex substitute is contingent upon system-level impedance requirements and RF signal integrity specifications.

Compliance Status

The Amphenol ICC 456-717 is classified as obsolete. The Molex 0731000223 maintains active product status with ROHS3 compliance certification, providing long-term supply chain continuity and regulatory alignment for applications requiring RoHS3 compliance.

Physical and Mechanical Alignment

Both components share identical mechanical form factors, mounting configurations, and fastening mechanisms. Solder termination specifications are consistent across both parts, enabling direct PCB integration without layout modifications.

Material and Contact Specifications

The Molex substitute incorporates gold-plated phosphor bronze contacts and polypropylene dielectric material, compared to tin-plated copper alloy contacts and polyester dielectric in the original part. These material differences may influence contact resistance, environmental durability, and long-term reliability characteristics in specific application environments.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0731000223 directly replace the Amphenol ICC 456-717 in all applications?

A: Direct replacement is limited by impedance specification differences. The Amphenol part operates at 75 Ohms while the Molex substitute operates at 50 Ohms. Substitution is valid only for applications where 50 Ohms impedance is acceptable or where impedance matching is not a critical system requirement.

Q: What are the mechanical compatibility considerations?

A: Both components feature identical BNC jack female socket configurations with panel mount, through-hole, right-angle solder termination and bayonet lock fastening. PCB footprints and mounting hole patterns are compatible, eliminating the need for layout redesign.

Q: How do the contact materials differ between these parts?

A: The Amphenol 456-717 uses tin-plated copper alloy contacts, while the Molex 0731000223 uses gold-plated phosphor bronze contacts. Gold plating provides enhanced corrosion resistance and lower contact resistance, potentially improving long-term reliability in high-cycle or harsh environments.

Q: Are there compliance differences between these components?

A: The Amphenol part carries RoHS compliance certification, while the Molex substitute carries ROHS3 compliance certification. ROHS3 represents an updated compliance standard with additional restricted substance requirements. The Molex part is suitable for applications requiring current RoHS3 compliance.

Q: What is the significance of the dielectric material difference?

A: The Amphenol part uses polyester dielectric material while the Molex substitute uses polypropylene (PP). Polypropylene offers superior moisture resistance and lower dielectric loss characteristics, which may provide performance advantages in high-frequency RF applications or humid operating environments.

Q: Does the packaging difference affect component selection?

A: The Molex 0731000223 is supplied in bag packaging and includes three pieces per connector unit (1 connector, 1 lockwasher, 1 nut). The Amphenol part packaging specification is not provided. Verify packaging requirements for your procurement and assembly processes.

Q: What is the operating temperature compatibility?

A: The Amphenol 456-717 specifies an operating temperature range of -20°C to 85°C. The Molex 0731000223 does not provide an operating temperature specification in the available data. Confirm temperature range requirements for your application environment before substitution.
