Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1478238-0 with the Amphenol RF 112438 is based on functional and electrical equivalence across the following critical parameters:

Matching Parameters:

• Adapter type: Jack to jack configuration
• Adapter series: BNC to BNC
• Center gender: Female to female
• Impedance: 75 ohms
• Style: Straight
• Mounting type: Panel mount with bulkhead feature
• Fastening type: Bayonet lock mechanism
• Center contact plating: Gold
• Body material: Brass with nickel finish
• Dielectric material: PTFE/POM acetal
• Moisture sensitivity level: 1 (Unlimited)
• REACH and ECCN compliance: Both REACH Affected and EAR99

Operational Differences: The Amphenol RF 112438 operates at a maximum frequency of 2 GHz compared to the TE Connectivity part's 1 GHz specification, and supports an extended operating temperature range of -40°C to 85°C versus -40°C to 60°C. The substitute part is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 112438 serves as a direct functional equivalent to the obsolete TE Connectivity 1-1478238-0 for BNC jack-to-jack 75-ohm coaxial adapter applications. Both components meet identical mechanical and electrical interface requirements, including adapter type, impedance, mounting configuration, and fastening mechanism.

The Amphenol RF 112438 is the recommended selection for new designs and ongoing production due to its active product status, ensuring sustained component availability and manufacturer support. The substitute part maintains full compliance with REACH and RoHS3 regulations, meeting current regulatory requirements for electronic component procurement.

The extended frequency capability (2 GHz versus 1 GHz) and broader operating temperature range (-40°C to 85°C versus -40°C to 60°C) of the Amphenol RF part provide additional operational margin for applications within the original 1 GHz specification envelope. The dielectric material difference (POM acetal versus PTFE) does not affect functional compatibility for the specified 75-ohm impedance and frequency range.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112438 directly replace the TE Connectivity 1-1478238-0 in existing installations?

A: Yes. Both components share identical adapter type, impedance, mounting configuration, and fastening mechanism specifications. The Amphenol RF part is mechanically and electrically compatible for direct substitution in panel mount bulkhead applications requiring BNC jack-to-jack female-to-female connection.

Q: What is the significance of the product status difference between these parts?

A: The TE Connectivity 1-1478238-0 is classified as obsolete, indicating discontinued manufacturing and limited future availability. The Amphenol RF 112438 maintains active product status, ensuring ongoing production, inventory availability, and manufacturer technical support for component selection and procurement.

Q: Are there compliance differences between the two parts?

A: Both components are REACH Affected and classified as EAR99 for export control purposes. The Amphenol RF 112438 carries ROHS3 certification, while the TE Connectivity part carries RoHS Compliant status. Both meet current regulatory requirements for electronic component applications.

Q: How do the frequency specifications affect substitution suitability?

A: The TE Connectivity part specifies 1 GHz maximum frequency, while the Amphenol RF substitute operates to 2 GHz. For applications operating within the original 1 GHz specification, the higher frequency rating of the substitute part does not introduce compatibility issues and provides additional operational margin.

Q: What is the impact of the different dielectric materials?

A: The TE Connectivity part uses PTFE dielectric material, while the Amphenol RF substitute uses POM acetal. Both materials are suitable for 75-ohm impedance coaxial applications at the specified frequency ranges. The material difference does not affect functional compatibility for the intended application.

Q: Are there packaging considerations for component procurement?

A: The Amphenol RF 112438 is supplied in bag packaging. The TE Connectivity part packaging specification is not provided. Verify packaging requirements with procurement specifications to ensure compatibility with assembly and inventory management processes.

Q: What is the mating cycle rating for the Amphenol RF substitute?

A: The mating cycle specification for the Amphenol RF 112438 is not provided in the available technical data. The TE Connectivity part specifies 500 mating cycles. Contact the manufacturer for detailed mechanical durability specifications if mating cycle performance is a critical design parameter.
