Key Parameters

Substitute Part Grouping Explanation

Substitution of coaxial RF connectors is determined by strict equivalence across core electrical and mechanical parameters. The Amphenol RF 901-9758 and identified substitute parts share the following critical parameters that establish substitutability:

Electrical Parameters:

• Connector Style: SMA
• Connector Type: Receptacle, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Center Contact Material: Beryllium Copper
• Center Contact Plating: Gold

Mechanical Parameters:

• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Threaded
• Number of Ports: 1

Environmental & Compliance Parameters:

• Operating Temperature Range: -65°C ~ 165°C
• Mating Cycles: 500
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts meeting all these parameters are electrically and mechanically compatible for direct replacement in applications where the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 901-9758 and Cinch Connectivity Solutions 142-1701-191 are Active product status components with full ROHS3 compliance and REACH compliance status. Both parts satisfy identical electrical and mechanical requirements for 50 Ohm SMA female socket panel mount solder connectors.

The Cinch Connectivity Solutions 142-1701-191 provides extended frequency capability to 18 GHz compared to the Amphenol RF 901-9758 at 12.4 GHz maximum frequency. This extended frequency range does not restrict substitution for applications operating within the 12.4 GHz specification of the primary part.

Both parts maintain identical operating temperature ranges, mating cycle ratings, and environmental compliance classifications. Selection between these parts is based on availability, supply chain requirements, and packaging format (Amphenol RF 901-9758 packaging not specified; Cinch Connectivity Solutions 142-1701-191 supplied in Tray packaging).

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity Solutions 142-1701-191 directly replace the Amphenol RF 901-9758 in existing designs?

A: Yes. Both parts are SMA female socket receptacles with 50 Ohm impedance, solder termination, panel mount flange configuration, and threaded fastening. Electrical and mechanical parameters are equivalent. The substitute part supports extended frequency operation to 18 GHz, which does not restrict its use in applications specified for 12.4 GHz maximum.

Q: What is the difference between "Receptacle" and "Jack" connector terminology for these parts?

A: Both designations refer to female socket connectors in SMA connector families. The terminology difference reflects manufacturer nomenclature conventions and does not indicate functional or electrical differences. Both parts are mechanically and electrically compatible for mating with standard SMA male plugs.

Q: Are there packaging differences between the main part and substitute?

A: The Amphenol RF 901-9758 packaging format is not specified in available documentation. The Cinch Connectivity Solutions 142-1701-191 is supplied in Tray packaging. Packaging format does not affect electrical or mechanical compatibility for component-level applications.

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

A: Yes. Both parts are ROHS3 compliant, REACH affected, classified under ECCN EAR99, and carry identical HTSUS classification 8536.69.4010. Both operate across -65°C to 165°C temperature range with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the maximum frequency difference between these parts?

A: The Amphenol RF 901-9758 is rated to 12.4 GHz maximum frequency. The Cinch Connectivity Solutions 142-1701-191 is rated to 18 GHz maximum frequency. For applications operating at or below 12.4 GHz, the extended frequency rating of the substitute part does not create incompatibility.

Q: Are the solder termination specifications identical?

A: Yes. Both parts feature solder termination for both contact and shield connections. Both use Beryllium Copper center contacts with gold plating and PTFE dielectric material, ensuring equivalent electrical performance and solderability characteristics.
