Amphenol RF 82-5588 Equivalent & Substitute Parts

Part Overview

The Amphenol RF 82-5588 is a twinaxial coaxial connector adapter designed for jack-to-jack female socket connections. This adapter operates at frequencies up to 11 GHz with a non-constant impedance characteristic and supports operating temperatures from -65°C to 165°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 82-5588 is determined by the following critical parameters:

Mechanical Compatibility:

• Adapter type (jack to jack)
• Adapter series (twinaxial to twinaxial)
• Center gender configuration (female to female)
• Connector style (straight)
• Mounting type (free hanging, in-line)
• Fastening mechanism (threaded connections)

Material Specifications:

• Body material (brass)
• Body finish (nickel)
• Center contact material (phosphor bronze)
• Center contact plating (gold)

Environmental Specifications:

• Operating temperature range (-65°C to 165°C)

The Amphenol RF 082-5588-RFX satisfies all mechanical and material compatibility requirements. However, differences in impedance specification, frequency rating, dielectric material, and regulatory compliance status create distinct operational contexts for each part.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The Amphenol RF 082-5588-RFX is the active equivalent substitute for the 82-5588. Both parts share identical mechanical interfaces, material compositions, and environmental operating ranges. The 082-5588-RFX is currently in active production status with ROHS3 compliance certification, making it suitable for new designs and legacy system upgrades.

Operational Differences:

The 082-5588-RFX operates at a maximum frequency of 500 MHz with a defined 50-ohm impedance specification, compared to the 82-5588's 11 GHz capability with non-constant impedance. Applications requiring frequencies above 500 MHz or non-constant impedance characteristics require evaluation of the frequency and impedance requirements against the substitute part's specifications.

Regulatory Compliance:

The 082-5588-RFX carries ROHS3 compliance and REACH-affected status, whereas the 82-5588 is RoHS non-compliant and REACH unaffected. Systems subject to RoHS or REACH regulatory requirements must use the 082-5588-RFX.

Frequently Asked Questions (FAQ)

Q: Can the 082-5588-RFX directly replace the 82-5588 in existing assemblies?

A: Mechanical and material compatibility is complete. The 082-5588-RFX connects identically to twinaxial jack female sockets and operates across the same temperature range. Substitution is valid for applications operating at frequencies up to 500 MHz. Applications exceeding 500 MHz require frequency performance evaluation.

Q: What is the primary difference between these two parts?

A: The 82-5588 supports frequencies to 11 GHz with non-constant impedance. The 082-5588-RFX operates to 500 MHz with 50-ohm impedance. The 082-5588-RFX is the active production equivalent with current regulatory compliance.

Q: Are there packaging differences between the 82-5588 and 082-5588-RFX?

A: Packaging information is not specified for either part. Both are classified as free-hanging, in-line connectors with identical mechanical form factors.

Q: Which part should be selected for new designs?

A: The 082-5588-RFX is the active production part with ROHS3 compliance and is the appropriate selection for new designs. The 82-5588 is obsolete and should not be specified for new applications.

Q: Does the dielectric material difference affect substitution?

A: The 82-5588 uses PTFE dielectric material, while the 082-5588-RFX uses PBT and polyester. Both materials are suitable for the operating temperature range and mechanical requirements. The dielectric material difference contributes to the frequency rating difference between the parts.

Q: What is the impedance specification of the 82-5588?

A: The 82-5588 has non-constant impedance. The 082-5588-RFX has a defined 50-ohm impedance specification. Applications requiring non-constant impedance characteristics must retain the 82-5588 if available or identify alternative parts with matching impedance specifications.
