CONSMA014-R58 SMA Connector Receptacle Equivalent & Substitute Parts

Part Overview

The CONSMA014-R58 is an SMA connector receptacle manufactured by TE Connectivity Linx, designed for 50 Ohm coaxial RF applications. This female socket connector features solder contact termination and panel mount installation with bulkhead front side nut fastening. The part is actively produced and RoHS compliant, with 1121 units currently in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in the same application circuit. Substitution eligibility is determined by matching impedance, connector style, contact termination method, mounting configuration, and operating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CONSMA014-R58 are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Connector Style: SMA
• Connector Type: Receptacle, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Crimp
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Front Side Nut
• Frequency - Max: 12.4 GHz or higher
• Operating Temperature Range: -65°C ~ 165°C or wider
• Mating Cycles: 500 or higher

Allowable Variations:

• Cable Group: RG-58, RG-174, or RG-178 (different cable compatibility)
• Center Contact Material: Brass or Beryllium Copper
• Voltage Rating: Equal to or greater than 250 V
• Included accessories: May vary in quantity and type

The CONSMA005 and CONSMA014-R178 meet all mandatory matching parameters and are therefore qualified as parametric equivalents for the CONSMA014-R58.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CONSMA014-R58, CONSMA005, and CONSMA014-R178—are active products manufactured by TE Connectivity Linx and carry RoHS compliance certification. Selection between these equivalents is determined by cable group compatibility and voltage rating requirements for the specific application.

CONSMA014-R58 is specified for RG-58 cable applications and provides the highest voltage rating at 500 V with brass center contact material.

CONSMA005 is specified for RG-174 cable applications with a voltage rating of 335 V and beryllium copper center contact material, suitable for applications requiring smaller diameter cable.

CONSMA014-R178 is specified for RG-178 cable applications with a voltage rating of 250 V and beryllium copper center contact material, suitable for applications requiring the smallest diameter cable with additional accessory support.

Selection must be based on the cable group specified in the circuit design. All three parts maintain identical RF performance characteristics at 12.4 GHz maximum frequency and support the full operating temperature range of -65°C to 165°C.

Frequently Asked Questions (FAQ)

Q: Can CONSMA005 be used as a direct replacement for CONSMA014-R58?

A: CONSMA005 is a parametric equivalent only when the application circuit specifies RG-174 cable. The connector electrical and mechanical specifications are identical, but the cable group designation differs. Substitution is valid only if the PCB layout and cable routing accommodate RG-174 instead of RG-58.

Q: What is the difference between the three substitute parts?

A: The primary differences are cable group compatibility (RG-58, RG-174, or RG-178) and voltage rating (500 V, 335 V, or 250 V respectively). All three connectors maintain identical RF impedance, frequency response, and operating temperature specifications. The cable group determines the connector's internal geometry and contact sizing.

Q: Is CONSMA014-R178 suitable for high-voltage applications?

A: CONSMA014-R178 has a voltage rating of 250 V, which is lower than both CONSMA014-R58 (500 V) and CONSMA005 (335 V). Selection must be based on the maximum voltage present in the application circuit.

Q: Do all three parts have the same mating cycle rating?

A: Yes, all three parts support 500 mating cycles, indicating equivalent mechanical durability and connector longevity.

Q: What are the packaging considerations for these connectors?

A: All three parts are supplied in bag packaging and include various accessories. CONSMA014-R58 includes 7 pieces per connector unit, while CONSMA014-R178 includes 8 pieces per connector unit. Verify accessory requirements for your assembly process before substitution.

Q: Are all three parts RoHS compliant?

A: Yes, CONSMA014-R58, CONSMA005, and CONSMA014-R178 are all RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements.
