Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 132144 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain constant:

Connector style (SMA), connector type (Plug, Male Pin), impedance (50 Ohms), contact and shield termination method (Solder), mounting configuration (Panel Mount with Flange), fastening mechanism (Threaded), maximum frequency (12.4 GHz), operating temperature range (-65°C ~ 165°C), dielectric material (PTFE), body material (Brass), body finish (Gold), center contact plating (Gold), mating cycle rating (500), and port count (1).

The Amphenol RF 132145 qualifies as a parametric equivalent substitute. Both parts maintain identical specifications across all critical RF, mechanical, and environmental parameters. The only documented difference is the center contact material composition, which does not affect functional interchangeability within the specified electrical and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 132144 and Amphenol RF 132145 are Active product status components with full RoHS3 compliance and REACH affected status. Selection between these parts is based on inventory availability and application-specific requirements related to center contact material composition.

The 132144 features a beryllium copper center contact, while the 132145 uses a brass center contact. Both materials are suitable for 50-ohm SMA connector applications within the specified frequency range of 12.4 GHz and operating temperature envelope of -65°C to 165°C. The choice between these materials does not affect RF performance, impedance matching, or environmental compliance within the stated parameters.

Current inventory levels show 1612 pieces of the 132145 available compared to 1069 pieces of the 132144. Both parts carry identical electrical specifications, mechanical dimensions, and regulatory certifications. Selection should be based on supply chain requirements and material preference for the specific application.
