Key Parameters

Substitute Part Grouping Explanation

Substitution of the 031-6005-RFX is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Parameters: Impedance (50 Ohms), frequency rating (4 GHz maximum), voltage rating (500 V), and insertion loss (0.2 dB) must remain constant.

Mechanical Parameters: Connector style (BNC), connector type (Plug, Male Pin), mounting configuration (Free Hanging, Right Angle), contact termination method (Solder), and shield termination method (Crimp) must be identical.

Material and Environmental Parameters: Center contact material (Brass), body material (Brass), body finish (Nickel), center contact plating (Gold), dielectric material (Polyoxymethylene/POM Acetal), and mating cycle rating (500) must match.

Compliance Parameters: RoHS3 compliance and REACH affected status must be maintained.

The substitute part Amphenol RF 112601 satisfies all these requirements and is classified as an active product, making it suitable for new applications and ongoing support.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 112601 is the direct substitute for the 031-6005-RFX. All electrical, mechanical, and material specifications are identical. The primary distinction is product status: the 031-6005-RFX is classified as "Not For New Designs," while the 112601 is an active product.

For new designs and applications requiring long-term support, the 112601 is the appropriate selection. The 112601 maintains full compatibility with the same cable groups (Belden 9258 and LMR-240) and adds support for RG-8X cable. Both parts carry ROHS3 compliance and REACH affected status, ensuring regulatory alignment.

Packaging differs between the two parts: the 031-6005-RFX is supplied in bulk, while the 112601 is supplied in bag packaging. This distinction affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 112601 be used as a direct replacement for the 031-6005-RFX in existing assemblies?

A: Yes. The 112601 is electrically and mechanically identical to the 031-6005-RFX. All critical parameters including impedance, frequency rating, termination methods, and material specifications match exactly. The connector will function identically in existing cable assemblies and applications.

Q: What is the difference between bulk and bag packaging?

A: Bulk packaging (031-6005-RFX) typically refers to loose components supplied in larger quantities without individual packaging. Bag packaging (112601) indicates components are supplied in protective bags. This affects handling, storage, and inventory management but does not alter the connector's electrical or mechanical properties.

Q: Why is the 031-6005-RFX marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product line. The 112601 is the active equivalent and is recommended for all new applications. Existing inventory of the 031-6005-RFX may continue to be used for maintenance and repair of legacy systems.

Q: Are there cable compatibility differences between the two parts?

A: The 112601 supports an additional cable group (RG-8X) beyond those supported by the 031-6005-RFX. Both parts are compatible with Belden 9258 and LMR-240 cables. The expanded cable compatibility of the 112601 provides greater flexibility in cable selection.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 031-6005-RFX and 112601 are ROHS3 compliant and REACH affected. They carry identical compliance certifications and are suitable for applications with equivalent regulatory requirements.

Q: What is the maximum frequency rating for these connectors?

A: Both connectors are rated for frequencies up to 4 GHz, making them suitable for RF and microwave applications within this frequency range.

Q: How many mating cycles are these connectors rated for?

A: Both connectors are rated for 500 mating cycles, indicating the expected number of connect/disconnect operations before performance degradation.
