Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the Amphenol RF 031-6036 is based on the following critical parameters that determine functional equivalence:

Impedance Matching: Both the main part and substitute must maintain 50-ohm impedance to ensure signal integrity and prevent reflections in RF circuits.

Operating Temperature Range: The substitute must support the full operating temperature range of -65°C to 165°C to ensure reliability across environmental conditions.

Mounting Configuration: The substitute must be configured as a free-hanging (in-line) connector to match the mechanical installation requirements.

Termination Method: The substitute must support crimp termination to align with assembly processes and cable attachment specifications.

Compliance Standards: Both parts must maintain ROHS3 compliance and REACH compliance status for regulatory requirements.

The identified substitute part, Cinch Connectivity Solutions 142-0404-011, differs in connector style (SMA versus RP-BNC), connector type (male pin versus female socket), fastening mechanism (threaded versus bayonet lock), and maximum frequency capability (12.4 GHz versus 4 GHz). These differences indicate that this substitute is not a direct functional equivalent and represents a different connector family with distinct mechanical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The Amphenol RF 031-6036 remains the specified component for applications requiring RP-BNC connector architecture with bayonet locking mechanism and female socket configuration.

Compliance Verification: Both the main part and listed substitute maintain ROHS3 and REACH compliance, satisfying regulatory requirements for restricted substance management.

Inventory Availability: The Amphenol RF 031-6036 maintains active production status with 761 units in current stock inventory, ensuring supply continuity for standard procurement cycles.

Voltage and Temperature Ratings: The main part provides 500V voltage rating and full -65°C to 165°C operating range. The substitute part provides 250V voltage rating, which may be limiting in high-voltage applications.

Frequency Capability: The main part operates to 4 GHz maximum frequency. The substitute part extends to 12.4 GHz, providing additional frequency headroom for future application expansion, though this represents a different connector family.

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity Solutions 142-0404-011 directly replace the Amphenol RF 031-6036?

A: No. These components belong to different connector families. The 031-6036 uses RP-BNC style with bayonet locking and female socket configuration, while the 142-0404-011 uses SMA style with threaded locking and male pin configuration. Direct mechanical and electrical compatibility cannot be established without redesign of mating interfaces.

Q: What are the critical parameters for RP-BNC connector substitution?

A: Critical parameters include connector style (RP-BNC), connector type (female socket), impedance (50 ohms), fastening type (bayonet lock), contact termination (crimp), and operating temperature range (-65°C to 165°C). Any substitute must match all these parameters.

Q: Are both parts suitable for the same cable types?

A: No. The Amphenol RF 031-6036 is specified for RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cable groups. The Cinch Connectivity Solutions 142-0404-011 is specified for RG-188DS and 316DS cable groups. Cable compatibility differs between these connector families.

Q: What is the voltage rating difference between these parts?

A: The Amphenol RF 031-6036 is rated for 500V, while the Cinch Connectivity Solutions 142-0404-011 is rated for 250V. Applications requiring higher voltage ratings must use the main part specification.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH affected, and support the same operating temperature range of -65°C to 165°C. Both maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the maximum frequency difference?

A: The Amphenol RF 031-6036 operates to 4 GHz maximum frequency. The Cinch Connectivity Solutions 142-0404-011 operates to 12.4 GHz maximum frequency. The substitute provides extended frequency capability but represents a different connector architecture.
