CBNRABNF BNC Coaxial Adapter Connector - Equivalent & Substitute Parts

Part Overview

The CBNRABNF is a 50 Ohm coaxial adapter connector manufactured by TE Connectivity Laird. This component functions as a BNC Jack to BNC Plug adapter, converting female socket connections to male pin connections in a right-angle configuration. The part is classified as obsolete, making identification of active equivalent substitutes essential for ongoing system maintenance and new design implementations. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or performance degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CBNRABNF is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Adapter Type: Plug to Jack
• Adapter Series: BNC to BNC
• Center Gender Configuration: Female to Male
• Impedance: 50 Ohms
• Style: Right Angle
• Fastening Type: Bayonet Lock
• Frequency Maximum: 4 GHz or greater
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Plating: Gold
• Dielectric Material: Polyoxymethylene (POM) Acetal

Both identified substitute parts (112451 and 112453, both manufactured by Amphenol RF) satisfy all mandatory matching parameters. These parts are classified as active products, providing long-term availability and supply chain stability compared to the obsolete CBNRABNF.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 112453 (Amphenol RF)

Part 112453 is the preferred substitute for CBNRABNF applications. This part maintains complete electrical and mechanical equivalence across all critical parameters. As an active product with ROHS3 compliance and REACH compliance status, it provides superior supply chain continuity and regulatory alignment for modern manufacturing environments. Packaging in bag format supports flexible inventory management for both prototype and production quantities.

Secondary Recommendation: 112451 (Amphenol RF)

Part 112451 serves as an alternative substitute with identical electrical and mechanical specifications. This part is also active and ROHS3 compliant. The documented mating cycle rating of 500 cycles provides explicit mechanical durability specification. Bulk packaging format is suitable for high-volume production environments. Both 112451 and 112453 are manufactured by Amphenol RF, ensuring consistent quality standards and supply reliability.

Compliance Considerations

Both substitute parts carry ROHS3 and REACH compliance certifications, meeting current environmental and regulatory requirements. The CBNRABNF does not specify these certifications, making the substitutes advantageous for applications subject to modern regulatory frameworks. All three parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, confirming trade compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can 112451 or 112453 be used as direct replacements for CBNRABNF in existing assemblies?

A: Yes. Both parts satisfy all mandatory electrical and mechanical parameters. The adapter type, gender configuration, impedance, frequency rating, and physical construction are identical. Direct substitution is supported without circuit modification or performance impact.

Q: What is the difference between 112451 and 112453?

A: Both parts are electrically and mechanically equivalent. The primary differences are packaging format (112451 supplied in Bulk; 112453 supplied in Bag) and documented mating cycle specification (112451 specifies 500 cycles; 112453 does not specify this parameter). Selection between these parts depends on inventory management requirements and procurement volume.

Q: Why is CBNRABNF classified as obsolete?

A: The CBNRABNF is an obsolete product from TE Connectivity Laird. Amphenol RF 112451 and 112453 are active products offering equivalent functionality with modern compliance certifications and documented reliability specifications.

Q: Are there any frequency limitations when substituting these parts?

A: No. All three parts are rated to 4 GHz maximum frequency. Substitution does not introduce frequency limitations or bandwidth restrictions.

Q: Do the substitute parts support the same impedance specification?

A: Yes. All parts are rated at 50 Ohms impedance. Impedance matching is maintained across all substitutions.

Q: What is the operating temperature range for the substitute parts?

A: Both 112451 and 112453 are rated for -40°C to 85°C operating temperature. The original CBNRABNF does not specify an operating temperature range.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 112451 and 112453 are ROHS3 compliant. The original CBNRABNF does not specify RoHS compliance status.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes. Both substitute parts maintain identical electrical specifications and physical construction. The 112451 provides documented mating cycle specification (500 cycles), supporting reliability assessment for mechanical durability requirements.
