Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Compatibility):

The following parts are recommended as primary substitutes based on active product status, full ROHS3 compliance, and matching or exceeding all electrical specifications:

• Rosenberger 29K10H-40ML5: Active status, ROHS3 compliant, identical operating temperature and voltage ratings. Dielectric material differs (LCP vs. PTFE) but maintains electrical performance within specification.
• Cinch Connectivity Solutions 133-3711-202: Active status, ROHS3 compliant, exceeds operating temperature range (-65°C to 165°C), identical voltage rating, PTFE dielectric.
• Würth Elektronik 60612102111406: Active status, ROHS3 compliant, identical operating temperature and voltage ratings, PTFE dielectric, includes insertion loss specification (0.25 dB).
• Amphenol RF 919-384J-51PT: Active status, ROHS3 compliant, exceeds operating temperature range (-65°C to 165°C), PTFE dielectric.
• Samtec Inc. MCX-J-P-H-ST-SM1-TR: Active status, ROHS3 compliant, identical voltage rating, PTFE dielectric, operates to -65°C to 125°C.

Secondary Substitutes (Conditional Use):

• Huber+Suhner 82_MCX-S50-0-29/111_NM: Active status, ROHS3 compliant, but voltage rating (170 V) is below the original specification (335 V). Use only in applications where voltage requirements do not exceed 170 V. Available in Cut Tape packaging.
• IMS Connector Systems 2017.01.2510.003: Active status, but voltage rating (250 V) is below the original specification (335 V) and operating temperature maximum is limited to 125°C. Use only in applications where these reduced specifications are acceptable.

Not Recommended:

• TE Connectivity 966851-1: Product status is obsolete. While electrical specifications are compatible, obsolete status indicates discontinued production and potential supply chain limitations.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Rosenberger 162788 with any MCX connector jack?

A: No. Substitution requires matching specific parameters: 50 ohm impedance, female socket jack configuration, surface mount solder termination, snap-on fastening, and 6 GHz frequency rating. The connector style, type, and termination method must be identical.

Q: What is the difference between PTFE and LCP dielectric materials in these connectors?

A: Both PTFE and LCP are acceptable dielectric materials for MCX connectors operating at 6 GHz. PTFE (polytetrafluoroethylene) is the traditional material, while LCP (liquid crystal polymer) offers similar electrical performance. The choice depends on application-specific requirements not specified in this reference.

Q: Why do some substitute parts have lower voltage ratings?

A: The Huber+Suhner 82_MCX-S50-0-29/111_NM (170 V) and IMS Connector Systems 2017.01.2510.003 (250 V) have reduced voltage ratings compared to the original 335 V specification. These parts are suitable only for applications where the actual operating voltage does not exceed their rated values. Verify application requirements before selection.

Q: What is the significance of product status (Active vs. Obsolete)?

A: Active status indicates the part is currently in production and available from the manufacturer. Obsolete status indicates production has been discontinued. The TE Connectivity 966851-1 is obsolete, meaning future availability cannot be guaranteed. Active parts are preferred for new designs and long-term supply assurance.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats do not affect electrical or mechanical performance. The choice depends on assembly process requirements and quantity needs. Tape & Reel is standard for automated assembly, while Cut Tape is used for smaller quantities or manual assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Most substitute parts are ROHS3 compliant. The IMS Connector Systems 2017.01.2510.003 does not specify RoHS status in the provided data. Verify compliance requirements for your specific application before selection.

Q: Can I use the TE Connectivity 966851-1 despite its obsolete status?

A: The TE Connectivity 966851-1 meets all electrical and mechanical specifications and is currently in stock (15,701 units). However, obsolete status indicates no future production. Use this part only if immediate availability is critical and long-term supply is not required.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 indicates unlimited shelf life without moisture control requirements. All listed parts have MSL 1 rating, meaning they can be stored without special humidity or temperature controls.

Q: How do I verify compatibility before ordering a substitute part?

A: Confirm that the substitute part matches all mandatory parameters: MCX connector style, jack female socket type, 50 ohm impedance, surface mount solder termination, snap-on fastening, and 6 GHz frequency rating. Verify that operating temperature range and voltage rating meet or exceed your application requirements.
