Amphenol ICC 456-915 BNC Coaxial Connector Adapter Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 456-915 is a coaxial connector adapter designed for RF applications requiring BNC Jack to BNC Jack (Female to Female) conversion at 50 Ohms impedance. This component functions as a straight-through adapter with panel mount bulkhead configuration and bayonet locking mechanism.

The 456-915 carries an Obsolete product status, necessitating identification of functionally equivalent alternatives for ongoing system support and new design implementations. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure seamless integration into existing or new RF circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 456-915 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Jack to Jack configuration
• Adapter Series: BNC to BNC conversion
• Center Gender: Female to Female socket orientation
• Impedance: 50 Ohms characteristic impedance
• Style: Straight connector orientation
• Fastening Mechanism: Bayonet Lock engagement

Acceptable Variation Parameters:

• Mounting Type: Panel Mount (main part) versus Free Hanging In-Line (substitute) represents a functional difference in installation method but maintains electrical compatibility
• Dielectric Material: Thermoplastic versus PTFE represents material substitution with equivalent RF performance characteristics
• Center Contact Material: Phosphor Bronze versus Beryllium Copper represents material substitution with equivalent electrical performance

The Pomona Electronics 3283 satisfies all mandatory matching parameters and provides functional equivalence for RF signal transmission applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Pomona Electronics 3283

The Pomona Electronics 3283 serves as the functional equivalent for the obsolete Amphenol ICC 456-915. Both components provide identical RF electrical performance through matching impedance (50 Ohms), connector gender configuration (Female to Female), and bayonet locking mechanism.

The 3283 maintains Active product status with current manufacturing availability, ensuring supply chain continuity. The component carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component procurement. The specified operating temperature range of -65°C to 165°C provides defined thermal performance boundaries for system integration.

The primary distinction between these components is mounting configuration: the 456-915 provides panel mount bulkhead installation, while the 3283 offers free-hanging in-line mounting. This difference requires mechanical redesign consideration in applications where bulkhead panel mounting is the original design requirement. For applications permitting in-line adapter placement, the 3283 provides direct electrical substitution without performance degradation.

Material composition differences (Thermoplastic versus PTFE dielectric; Phosphor Bronze versus Beryllium Copper contact material) do not introduce electrical incompatibility. Both material sets maintain 50 Ohm impedance characteristics and gold-plated contact surfaces for reliable RF signal transmission.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 3283 replace the Amphenol ICC 456-915 in all applications?

A: The 3283 provides electrical equivalence for all RF signal transmission requirements. The primary consideration is mounting configuration: the 456-915 is designed for panel mount bulkhead installation, while the 3283 is configured for free-hanging in-line use. Applications requiring bulkhead panel mounting require mechanical redesign to accommodate the 3283's in-line configuration.

Q: What are the critical parameters that must match between the main part and substitute?

A: Substitution requires matching of adapter type (Jack to Jack), adapter series (BNC to BNC), center gender configuration (Female to Female), impedance (50 Ohms), style (Straight), and fastening mechanism (Bayonet Lock). These parameters ensure RF signal path continuity and mechanical connector compatibility.

Q: Does the dielectric material difference between Thermoplastic and PTFE affect RF performance?

A: Both dielectric materials maintain the specified 50 Ohm impedance characteristic. Material selection represents manufacturing variation without electrical performance impact for the specified RF frequency range.

Q: Are there compliance or certification differences between these components?

A: The 456-915 carries RoHS Compliant certification. The 3283 carries ROHS3 Compliant certification, representing a more current regulatory standard. Both components meet environmental compliance requirements for electronic component procurement.

Q: What is the significance of the mounting type difference?

A: The 456-915 provides panel mount bulkhead configuration for fixed installation through a panel or enclosure wall. The 3283 provides free-hanging in-line configuration for cable-to-cable adapter applications. Selection depends on the mechanical installation method required by the application.

Q: Does the center contact material difference affect electrical performance?

A: Both Phosphor Bronze and Beryllium Copper contact materials with gold plating provide equivalent electrical conductivity and contact reliability for RF applications. Material selection represents manufacturing variation without performance impact.

Q: Is the operating temperature range specification critical for substitution?

A: The 3283 specifies an operating temperature range of -65°C to 165°C. The 456-915 does not provide a specified operating temperature range. Applications requiring operation within the 3283's specified range can proceed with substitution. Applications with temperature requirements outside this range require verification against the original 456-915 specifications or alternative component evaluation.
