MMCX-6105 Equivalent & Substitute Parts

Part Overview

The MMCX-6105 is a MMCX Connector Plug with male pin configuration, 50 ohm impedance, and crimp termination for free hanging (in-line) applications. Manufactured by Harwin Inc., this component is rated for RF applications up to 6 GHz and is compatible with RG-174, RG-188, and RG-316 cable groups. The part is currently obsolete, making identification of equivalent and substitute components essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMCX-6105 is determined by strict equivalence across the following critical parameters:

• Connector Style & Type: MMCX Plug, Male Pin configuration
• Electrical Specifications: 50 ohm impedance, 170 V voltage rating, 6 GHz maximum frequency
• Termination Method: Crimp contact and shield termination
• Mounting Configuration: Free hanging (in-line) with snap-on fastening
• Cable Compatibility: RG-174, RG-188, RG-316 cable groups
• Material & Finish: Brass body with gold finish, gold-plated center contact
• Dielectric Material: PTFE or equivalent (PFA/PTFE combinations acceptable)
• Compliance: RoHS3 compliance and REACH unaffected status

Three substitute parts meet these criteria: 1310A204M (Winchester Interconnect), 11_MMCX-50-2-3/111_OE (Huber+Suhner), and 11_MMCX-50-2-3/111_OH (Huber+Suhner). All three maintain functional and electrical equivalence to the original MMCX-6105 specification.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the MMCX-6105 across core RF and mechanical specifications. Selection should be based on product availability and compliance requirements:

1310A204M (Winchester Interconnect) is an active product with immediate availability (990 pcs in stock). This part maintains full electrical and mechanical equivalence. The operating temperature range (-40°C to 65°C) is narrower than the original MMCX-6105, which should be evaluated against application requirements.

11_MMCX-50-2-3/111_OE and 11_MMCX-50-2-3/111_OH (Huber+Suhner) are both active products with strong inventory levels (720 and 917 pcs respectively). Both parts feature beryllium copper center contacts, which provide enhanced durability compared to the brass center contact of the original part. Operating temperature range (-55°C to 155°C) is comparable to the MMCX-6105. Both parts carry ROHS3 compliance and REACH unaffected status, matching the original specification.

All three substitutes are ECCN EAR99 classified and share the same HTSUS code (8536.69.4010) as the original part.

Frequently Asked Questions (FAQ)

Q: Can the 1310A204M be used in applications requiring the full -65°C to 165°C temperature range of the MMCX-6105?

A: The 1310A204M operates within -40°C to 65°C. Applications requiring the full original temperature range should use the Huber+Suhner equivalents (11_MMCX-50-2-3/111_OE or 11_MMCX-50-2-3/111_OH), which support -55°C to 155°C operation.

Q: What is the difference between the two Huber+Suhner parts (11_MMCX-50-2-3/111_OE and 11_MMCX-50-2-3/111_OH)?

A: Both parts are electrically and mechanically identical. The designation difference reflects internal Huber+Suhner product coding. Either part is suitable for substitution.

Q: Are the substitute parts compatible with RG-174, RG-188, and RG-316 cables?

A: Yes. All three substitute parts are rated for the same cable groups as the MMCX-6105 and use identical crimp termination methods.

Q: Does the beryllium copper center contact in the Huber+Suhner parts affect compatibility?

A: No. Beryllium copper is a standard material for MMCX connector center contacts and provides equivalent electrical performance with enhanced mechanical durability. The parts remain fully compatible with existing mating connectors.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1310A204M is RoHS compliant. The Huber+Suhner parts (11_MMCX-50-2-3/111_OE and 11_MMCX-50-2-3/111_OH) are ROHS3 compliant, matching the original MMCX-6105 specification.

Q: What is the insertion loss specification for the substitute parts?

A: Insertion loss data is not provided for the 1310A204M or Huber+Suhner parts. The original MMCX-6105 specifies 0.2 dB insertion loss. For applications with strict insertion loss requirements, contact the respective manufacturers for detailed RF performance data.
