Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 262127 with the Cinch Connectivity Solutions 135-3436-001 is based on equivalence across the following critical parameters:

Electrical Compatibility:

• Both connectors maintain 50-ohm impedance specification
• Identical frequency maximum rating of 6 GHz
• Matching voltage rating of 170 V
• Equivalent mating cycle rating of 500 cycles

Mechanical Compatibility:

• Both utilize MMCX connector style with male pin configuration
• Identical snap-on fastening mechanism
• Free-hanging in-line mounting type
• Single port configuration

Material and Environmental Compliance:

• Brass body with gold finish on both parts
• PTFE dielectric material in both connectors
• Both achieve RoHS3 compliance
• Both are REACH affected

Termination Flexibility: The Cinch 135-3436-001 offers crimp or solder contact termination, whereas the Amphenol 262127 specifies solder-only termination. This provides design flexibility for applications where crimp termination may be preferred or required. The shield termination differs (solder on Amphenol versus crimp on Cinch), requiring evaluation based on specific assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 262127 and Cinch Connectivity Solutions 135-3436-001 are active production parts with full RoHS3 and REACH compliance, qualifying them for use in regulated applications and modern electronic assemblies.

Selection based on termination method:

• Choose Amphenol RF 262127 when solder termination for both contact and shield is specified in assembly procedures or when solder-only processes are mandated.
• Choose Cinch 135-3436-001 when crimp termination for the shield is preferred or when contact termination flexibility (crimp or solder) is required.

Selection based on contact material:

• Amphenol RF 262127 uses brass center contact material.
• Cinch 135-3436-001 uses beryllium copper center contact material, which may provide enhanced electrical performance characteristics in specific RF applications.

Selection based on environmental specifications:

• Cinch 135-3436-001 provides explicit operating temperature range of -55°C to 155°C and specified insertion loss of 0.1 dB, offering documented performance parameters for temperature-critical or high-precision RF applications.

Both parts maintain electrical equivalence at 50 ohms, 6 GHz maximum frequency, 170 V voltage rating, and 500 mating cycles, ensuring functional interchangeability in standard RF coaxial connector applications.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 135-3436-001 be used as a direct replacement for the Amphenol RF 262127?

A: The Cinch 135-3436-001 is electrically and mechanically equivalent for RF coaxial applications. Both maintain 50-ohm impedance, 6 GHz frequency rating, and identical mechanical mounting. The primary difference is termination method: Amphenol specifies solder-only termination, while Cinch offers crimp or solder flexibility. Substitution is valid when assembly procedures accommodate the Cinch termination options.

Q: What is the difference in center contact material between these connectors?

A: The Amphenol RF 262127 uses brass center contact material, while the Cinch 135-3436-001 uses beryllium copper. Both are gold-plated. Beryllium copper offers different mechanical and electrical properties that may be beneficial in specific RF applications, though both materials are suitable for 50-ohm RF coaxial connections.

Q: Are both connectors compliant with environmental regulations?

A: Yes. Both the Amphenol RF 262127 and Cinch 135-3436-001 are RoHS3 compliant and REACH affected, meeting current environmental and regulatory requirements for electronic components in regulated markets.

Q: What is the significance of the shield termination difference?

A: The Amphenol RF 262127 specifies solder shield termination, while the Cinch 135-3436-001 specifies crimp shield termination. The selection between these depends on assembly process capabilities and design requirements. Solder termination requires soldering equipment and procedures, while crimp termination requires crimp tooling and dies. Both methods achieve equivalent electrical shielding when properly executed.

Q: Does the Cinch connector provide any performance advantages?

A: The Cinch 135-3436-001 provides documented specifications for operating temperature range (-55°C to 155°C) and insertion loss (0.1 dB), which are not specified for the Amphenol RF 262127. These documented parameters may be advantageous for applications requiring explicit performance verification or operation in temperature-extreme environments.

Q: Are the mating cycles equivalent between these connectors?

A: Yes. Both connectors are rated for 500 mating cycles, indicating equivalent mechanical durability and expected service life in applications involving repeated connection and disconnection.

Q: What packaging differences exist between these parts?

A: The Amphenol RF 262127 is supplied in bag packaging, while the Cinch 135-3436-001 is supplied in bulk packaging. Packaging selection may affect inventory management, handling procedures, and cost considerations but does not impact electrical or mechanical performance.
