Equivalent & Substitute Parts for Amphenol ICC 456-717F BNC Connector

Part Overview

The Amphenol ICC 456-717F is a BNC jack straight coaxial connector classified as an RF connector. This component is currently obsolete, which necessitates identification of functionally equivalent substitute parts for ongoing maintenance, repair, and legacy system support. The obsolete status requires engineers to evaluate active alternative components that maintain electrical and mechanical compatibility with existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 456-717F is based on the following critical parameters that define functional equivalence in BNC coaxial connector applications:

Primary Substitution Criteria:

• Connector category: Coaxial Connectors (RF)
• Connector style: BNC
• Connector type: Jack configuration
• Impedance matching: 75 Ohms (standard RF impedance)
• Fastening mechanism: Bayonet Lock (BNC standard)

The substitute part Molex 0731010120 satisfies these core electrical and mechanical requirements. While the 456-717F mounting configuration is not fully specified in available data, the 0731010120 provides a panel mount, through-hole, right-angle configuration with bayonet locking, which represents the standard BNC jack implementation for RF applications.

Engineering Selection Recommendations

For 456-717F Replacement:

The Molex 0731010120 is an active, in-production BNC jack connector suitable for substitution. Selection is based on the following factors:

• Product Status: The 456-717F is obsolete; the 0731010120 is active with 12,852 units in stock, ensuring supply chain continuity.
• Compliance: Both parts are RoHS compliant. The 0731010120 carries ROHS3 compliance, meeting current regulatory requirements.
• Connector Category: Both are BNC coaxial RF connectors with jack (female socket) configuration.
• Electrical Specification: The 0731010120 specifies 75 Ohms impedance, the standard for BNC RF applications.
• Mechanical Interface: The 0731010120 features bayonet locking, the standard BNC fastening mechanism.
• Termination Method: Solder termination on both signal and shield contacts is standard for through-hole PCB mounting.

Qualification Requirement: Physical verification of mounting footprint compatibility is necessary before production implementation, as the 456-717F mounting configuration is not fully documented.

Frequently Asked Questions (FAQ)

Q: Why is the 456-717F obsolete? A: The 456-717F has been discontinued by Amphenol ICC. Obsolete status indicates the manufacturer no longer produces this component. The Molex 0731010120 provides equivalent BNC jack functionality in an active product line.

Q: What does "BNC Jack" mean? A: In BNC connector terminology, "jack" refers to the female socket configuration that receives a male plug. The 456-717F and 0731010120 are both female socket connectors.

Q: Are the impedance specifications compatible? A: The 456-717F impedance is not specified in available documentation. The 0731010120 is rated at 75 Ohms, which is the standard impedance for BNC RF connectors. Compatibility depends on the original 456-717F impedance specification.

Q: What is the difference between straight and right-angle mounting? A: The 456-717F is described as "straight" (axial orientation), while the 0731010120 is "right-angle" (90-degree orientation). These represent different physical mounting configurations. Mounting compatibility must be verified against the PCB layout and mechanical constraints of the target application.

Q: Can I use the 0731010120 as a direct drop-in replacement? A: The 0731010120 is electrically equivalent as a BNC jack connector. However, the mounting orientation difference (straight vs. right-angle) and unspecified mounting features of the 456-717F require physical verification before implementation.

Q: What is the mating cycle rating? A: The 0731010120 is rated for 500 mating cycles. This specification is not provided for the 456-717F. The 500-cycle rating is typical for standard BNC connectors in non-high-cycle applications.

Q: Are there RoHS compliance differences? A: Both parts are RoHS compliant. The 0731010120 carries ROHS3 certification, which represents the current RoHS directive standard. Both parts meet environmental compliance requirements.

Q: What packaging is provided? A: The 456-717F packaging is not specified. The 0731010120 is supplied in bag packaging, standard for individual connector components.
