MMCX Connector Plug R110081020 Equivalent & Substitute Parts

Part Overview

The Radiall USA R110081020 is an MMCX connector plug featuring a male pin configuration with 50 ohms impedance, designed for free hanging (in-line) crimp termination applications. This component is classified as an active product and is utilized in RF coaxial cable assemblies requiring snap-on fastening and high-frequency signal transmission up to 6 GHz. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate multiple qualified suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R110081020 are qualified based on strict parametric equivalence across all critical RF and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

Connector style (MMCX), connector type (plug, male pin), impedance (50 ohms), mounting type (free hanging in-line), contact and shield termination method (crimp), fastening type (snap-on), maximum frequency (6 GHz), compatible cable groups (RG-178, 196), operating temperature range (-55°C to 155°C), voltage rating (170 V), and mating cycle rating (500 cycles).

The identified substitute part maintains all these parameters, ensuring direct functional and mechanical compatibility within RF coaxial cable assembly applications. Variations in center contact material and dielectric composition do not affect substitution eligibility when all electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the R110081020 and the 11_MMCX-50-1-1/111_OH are active products with ROHS3 compliance and EAR99 export classification. Selection between these parts is based on availability and supply chain requirements rather than technical performance differentiation, as all critical electrical and mechanical parameters are equivalent.

The R110081020 from Radiall USA features a brass center contact material, while the 11_MMCX-50-1-1/111_OH from Huber+Suhner utilizes beryllium copper for the center contact. Both configurations meet the specified impedance, frequency, temperature, and voltage requirements. The dielectric material composition differs slightly (PTFE in the Radiall part versus PFA and PTFE in the Huber+Suhner part), but both materials satisfy the electrical performance specifications for this connector class.

Current inventory levels show 854 pieces of the R110081020 and 1573 pieces of the 11_MMCX-50-1-1/111_OH available as new original stock. Both parts carry identical HTSUS and ECCN classifications, supporting equivalent regulatory and compliance status.

Frequently Asked Questions (FAQ)
