MMCX-6005 Equivalent & Substitute Parts

Part Overview

The Harwin Inc. MMCX-6005 is a 50 Ohm MMCX connector plug with male pin configuration, designed for free hanging (in-line) applications using crimp termination. This component operates across a frequency range up to 6 GHz and supports RG-178 and RG-196 cable groups with snap-on fastening. The MMCX-6005 is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitute parts for the MMCX-6005 are identified based on strict parameter alignment across the following critical criteria:

Core Electrical Parameters: Connector style (MMCX), connector type (plug, male pin), impedance (50 Ohms), frequency maximum (6 GHz), voltage rating (170 V), and mating cycles (500).

Mechanical Parameters: Mounting type (free hanging/in-line), fastening type (snap-on), cable group compatibility (RG-178, 196), body material (brass), body finish (gold), and dielectric material (PTFE or compatible alternatives).

Termination Parameters: Contact termination method and shield termination method must be compatible with the application requirements.

Compliance Parameters: RoHS3 compliance and MSL rating (1 - Unlimited) are maintained across all substitutes.

Substitutes are grouped into two categories:

Direct Manufacturer Recommended: Parts with identical or superior specifications from active manufacturers, including alternative termination methods where electrically and mechanically compatible.

Parametric Equivalents: Parts meeting all core electrical and mechanical parameters with minor variations in center contact material or dielectric composition that do not affect functional performance within specified operating ranges.

Engineering Selection Recommendations

For Crimp Termination Applications:

The Huber+Suhner parts (11_MMCX-50-1-1/111_OE and 11_MMCX-50-1-1/111_OH) and Radiall parts (R110081020 and R110081020W) are direct parametric equivalents with active product status. These parts maintain crimp contact and shield termination identical to the MMCX-6005. The Huber+Suhner and Radiall options are suitable for designs requiring crimp-only termination methods.

For Flexible Termination Applications:

The Cinch Connectivity Solutions part 135-3402-001 offers both crimp and solder contact termination options within a single part number, providing design flexibility. This part is manufacturer-recommended and maintains active product status with ROHS3 compliance.

For Solder Termination Applications:

The Molex part 0734150971 provides solder contact termination with crimp shield termination. This option is suitable for applications where solder assembly is preferred over crimp methods.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL rating 1 (Unlimited). The Cinch and Molex parts carry REACH Affected status, while Huber+Suhner and Radiall parts are REACH Unaffected. Selection should account for supply chain compliance requirements specific to the end application region.

Temperature Range Considerations:

The MMCX-6005 specifies an operating temperature range of -65°C to 165°C. All substitute parts operate within -55°C to 165°C or -55°C to 155°C ranges. Applications requiring operation below -55°C should evaluate the original part's extended lower temperature specification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0734150971 replace the MMCX-6005 in a crimp-only assembly?

A: No. The Molex 0734150971 features solder contact termination, not crimp. For crimp-only applications, select from the Huber+Suhner (11_MMCX-50-1-1/111_OE or 11_MMCX-50-1-1/111_OH), Radiall (R110081020 or R110081020W), or Cinch (135-3402-001) options.

Q: What is the difference between the Huber+Suhner 11_MMCX-50-1-1/111_OE and 11_MMCX-50-1-1/111_OH?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is the MSL rating: 11_MMCX-50-1-1/111_OE carries MSL 1 (Unlimited), while 11_MMCX-50-1-1/111_OH carries MSL Not Applicable. Selection depends on moisture sensitivity requirements for your assembly process.

Q: Are the Radiall R110081020 and R110081020W interchangeable?

A: Yes. Both parts are parametric equivalents with identical specifications. The designation difference (with and without "W") does not reflect functional or electrical differences relevant to substitution.

Q: Does the Cinch 135-3402-001 support both crimp and solder termination simultaneously?

A: The Cinch part supports crimp or solder contact termination. The specific termination method is selected during assembly based on application requirements, not both simultaneously on a single connector.

Q: What is the impact of center contact material differences between brass and beryllium copper?

A: Both materials meet the specified electrical and mechanical parameters for 50 Ohm MMCX connectors. The material difference does not affect impedance, frequency response, or mating cycle performance within the specified operating ranges.

Q: Can I use a substitute part if my application requires operation below -55°C?

A: The MMCX-6005 specifies -65°C minimum operating temperature, while all substitute parts specify -55°C minimum. Applications requiring operation below -55°C should evaluate alternative sourcing or design modifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification. However, Cinch and Molex parts are REACH Affected, while Huber+Suhner and Radiall parts are REACH Unaffected. Verify REACH compliance requirements for your specific supply chain and end-use region.

Q: What does "Free Hanging (In-Line)" mounting mean?

A: Free hanging (in-line) indicates the connector is designed for direct cable attachment without panel or PCB mounting. The connector terminates directly to the cable conductor and shield without additional mounting hardware or brackets.
