Amphenol RF 262125 MMCX Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 262125 is an MMCX connector jack designed as a female socket with 50 ohm impedance for RF applications. This component features solder termination for both center contact and shield, operates at frequencies up to 6 GHz, and is rated for 170 V with 500 mating cycles. The part is Active status and RoHS3 compliant, making it suitable for modern electronic assemblies requiring miniature coaxial connectivity in free-hanging (in-line) configurations.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across alternative manufacturers, even when termination methods or packaging configurations differ.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for MMCX connector jacks is determined by strict equivalence in the following core parameters:

Electrical Equivalence Requirements:

• Connector style must be MMCX
• Connector type must be Jack, Female Socket
• Impedance must be 50 Ohms
• Frequency maximum must be 6 GHz or greater
• Voltage rating must be 170 V or greater
• Mating cycles must be 500 or greater

Mechanical Equivalence Requirements:

• Mounting type must be Free Hanging (In-Line)
• Fastening type must be Snap-On
• Center contact material must be Beryllium Copper
• Body material must be Brass
• Dielectric material must be Polytetrafluoroethylene (PTFE)

Compliance Requirements:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

Termination Flexibility: Contact termination methods (solder, crimp, or solder/crimp combination) are interchangeable when the electrical and mechanical parameters remain equivalent. Shield termination variations are acceptable when core RF performance is maintained.

Engineering Selection Recommendations

Amphenol RF 262125 Selection Criteria:

• Primary choice when solder termination for both center contact and shield is required by assembly process specifications
• Suitable for applications where bag packaging is preferred for component handling and traceability
• Active product status with established supply chain and 956 pcs inventory availability

Cinch Connectivity Solutions 135-3336-001 Selection Criteria:

• Equivalent electrical and mechanical performance with documented insertion loss specification of 0.1 dB
• Flexible termination options (crimp or solder) accommodate varied assembly methodologies
• Crimp shield termination may be preferred in high-volume automated assembly environments
• Operating temperature range explicitly specified (-55°C ~ 155°C) for applications requiring temperature performance documentation
• Bulk packaging suitable for high-volume procurement with 1107 pcs inventory availability
• Active product status with RoHS3 and REACH compliance maintained

Compliance Verification: Both parts maintain ROHS3 compliance, REACH affected status, and identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications, confirming regulatory equivalence for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can Cinch 135-3336-001 directly replace Amphenol RF 262125 in existing assemblies?

A: Electrical and mechanical compatibility is confirmed across all core parameters. The primary difference is shield termination method (crimp versus solder). Assembly process compatibility depends on whether the existing process accommodates crimp termination. Contact termination remains compatible via the solder option on the Cinch part.

Q: What is the significance of the different packaging (Bag versus Bulk)?

A: Packaging affects component handling, traceability, and procurement logistics but does not impact electrical or mechanical performance. Bag packaging typically supports smaller order quantities and individual component tracking. Bulk packaging is optimized for high-volume production environments.

Q: Are the cable group specifications interchangeable?

A: Amphenol RF 262125 specifies 0.047" semi-rigid cable compatibility. Cinch 135-3336-001 lists compatible cables as Axon P512479A 0.047" diameter flexible and Huber K01152-07. Cable compatibility must be verified against specific assembly requirements, as semi-rigid versus flexible cable properties differ mechanically.

Q: Does the insertion loss specification of 0.1 dB on the Cinch part indicate superior performance?

A: The Cinch part provides explicit insertion loss documentation at 0.1 dB. The Amphenol part does not specify this parameter in the provided data. Both parts operate at identical frequency (6 GHz maximum) and impedance (50 Ohms), indicating equivalent RF performance characteristics. The documented specification on the Cinch part provides additional design verification data.

Q: What is the impact of different mating cycle ratings if both are rated at 500?

A: Both parts are rated for 500 mating cycles, indicating equivalent mechanical durability and connector life expectancy under normal operating conditions.

Q: Are RoHS3 and REACH compliance identical between both parts?

A: Both parts are ROHS3 compliant and REACH affected, confirming equivalent environmental and regulatory compliance status for procurement and assembly in regulated markets.
