Amphenol RF 901-9704 SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 901-9704 is an SMA connector jack, female socket configuration rated for 50 ohms impedance. This coaxial RF connector is designed for free hanging (in-line) solder termination applications with RG-402 semi-rigid cable (.141" diameter). The part is currently active in production with 672 units in stock inventory. Alternative equivalent parts are necessary to support supply chain flexibility, procurement options from multiple manufacturers, and inventory management across distributed sourcing channels.

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 901-9704 are qualified based on strict parametric equivalence across the following critical specifications:

Mandatory Matching Parameters:

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Free Hanging (In-Line)
• Cable Group: RG-402 (.141" Semi Rigid)
• Fastening Type: Threaded
• Frequency - Max: 18 GHz
• Number of Ports: 1
• Center Contact Material: Beryllium Copper
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Mating Cycles: 500
• RoHS Status: ROHS3 Compliant

All identified substitute parts meet these mandatory parameters. Variations in body material composition, body finish specifications, operating temperature ranges, and voltage ratings do not disqualify substitution eligibility when all core RF and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts—Amphenol RF 901-9704, Cinch Connectivity Solutions 142-0594-001, and Radiall USA, Inc. R125225000—are active production components with ROHS3 compliance and REACH affected status. Selection between these parts is determined by application-specific operating temperature requirements and inventory availability.

Amphenol RF 901-9704 and Cinch 142-0594-001 both support the full operating temperature range of -65°C to 165°C. The Cinch part offers higher inventory availability (886 units) compared to the Amphenol part (672 units).

Radiall R125225000 operates within a reduced temperature range of -65°C to 105°C. This part is suitable for applications that do not require operation above 105°C. The Radiall part provides the highest inventory availability at 994 units.

All three parts carry identical RF performance specifications, mechanical compatibility, and regulatory compliance certifications. Selection should be based on temperature operating envelope requirements and procurement lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can Cinch 142-0594-001 directly replace Amphenol RF 901-9704 in all applications?

A: Yes, the Cinch 142-0594-001 is a parametric equivalent across all critical RF and mechanical specifications. Both parts support identical frequency response (18 GHz maximum), impedance (50 ohms), and operating temperature range (-65°C to 165°C). The primary difference is body material composition (brass versus stainless steel), which does not affect electrical performance or mechanical compatibility.

Q: What is the operating temperature limitation of the Radiall R125225000?

A: The Radiall R125225000 operates within the temperature range of -65°C to 105°C. This part is not suitable for applications requiring sustained operation above 105°C. The Amphenol RF 901-9704 and Cinch 142-0594-001 both support extended temperature operation up to 165°C.

Q: Are all three parts RoHS3 compliant?

A: Yes. The Amphenol RF 901-9704, Cinch 142-0594-001, and Radiall R125225000 are all ROHS3 compliant and REACH affected. All parts meet current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference in packaging between these parts?

A: Amphenol RF 901-9704 is supplied in standard packaging. Cinch 142-0594-001 is supplied in bulk packaging and includes 2 pieces per package (1 connector and 1 contact). Radiall R125225000 is supplied in box packaging. Packaging format does not affect connector performance or compatibility.

Q: Do all three parts support the same mating cycle rating?

A: Yes. All three parts are rated for 500 mating cycles, indicating equivalent mechanical durability and connector longevity under normal use conditions.

Q: Which part should be selected for high-temperature applications?

A: For applications requiring operation above 105°C, select either the Amphenol RF 901-9704 or Cinch 142-0594-001, both rated to 165°C. The Radiall R125225000 is limited to 105°C maximum operating temperature.

Q: Are the center contact materials identical across all three parts?

A: Yes. All three parts use beryllium copper center contact material with gold plating, ensuring consistent electrical performance and contact reliability.
