Amphenol RF 901-10024-RFX SMA Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 901-10024-RFX is an SMA connector plug designed for RF coaxial applications requiring 50-ohm impedance. This male pin connector features solder termination for the center contact and crimp termination for the shield, operating across a frequency range up to 12.4 GHz. The connector is rated for free-hanging (in-line) mounting with a threaded fastening mechanism. As an active product with ROHS3 compliance and REACH affected status, equivalent substitute parts may be required for supply chain continuity, design flexibility, or specific application requirements where alternative termination methods or cable compatibility profiles are beneficial.

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 901-10024-RFX with the Cinch Connectivity Solutions Johnson 142-0404-016 is based on electrical and mechanical parameter alignment within the SMA connector plug category. Both parts share identical core specifications: SMA connector style, male pin configuration, 50-ohm impedance, free-hanging in-line mounting, threaded fastening, 12.4 GHz maximum frequency, -65°C to 165°C operating temperature range, and 500 mating cycles. Both connectors feature brass bodies with nickel finish, gold-plated brass center contacts, and PTFE dielectric material. Both are ROHS3 compliant, REACH affected, and classified under EAR99 export control.

The primary distinction between these parts lies in center contact termination methodology and cable group compatibility. The main part (901-10024-RFX) specifies solder termination for the center contact and is compatible with RG-179, 188, 316 double braid, and M17/152-RD316 cable groups. The substitute part (142-0404-016) offers crimp or solder termination flexibility for the center contact and is compatible with RG-188DS and 316DS cable groups. Both parts employ crimp termination for the shield. The voltage rating differs: the main part is rated at 375 V, while the substitute is rated at 250 V. The substitute part includes 3 pieces (connector, contact, sleeve) compared to the main part's 4 pieces (connector, contact, ferrule, heat shrink).

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 901-10024-RFX and Cinch Connectivity Solutions Johnson 142-0404-016 are active products with identical ROHS3 compliance and REACH affected status, making them suitable for applications requiring regulatory adherence. Selection between these parts should be based on termination methodology requirements and cable group compatibility.

The Amphenol RF 901-10024-RFX is specified for solder termination of the center contact and is compatible with RG-179, 188, 316 double braid, and M17/152-RD316 cable groups. This configuration is appropriate for applications where solder termination is the preferred assembly method and where compatibility with these specific cable types is required.

The Cinch Connectivity Solutions Johnson 142-0404-016 offers flexibility through crimp or solder termination options for the center contact and is compatible with RG-188DS and 316DS cable groups. This part is suitable for applications where either termination method is acceptable or where the specific cable group compatibility profile aligns with system requirements.

The voltage rating differential (375 V for the main part versus 250 V for the substitute) must be evaluated against application voltage specifications. Applications requiring the higher 375 V rating necessitate the Amphenol RF part. Applications operating at or below 250 V can utilize either part.

Both parts maintain identical electrical performance characteristics across frequency, impedance, operating temperature, and mating cycle specifications, ensuring functional equivalence within their respective application scopes.

Frequently Asked Questions (FAQ)

Q: Can the Cinch Connectivity Solutions Johnson 142-0404-016 directly replace the Amphenol RF 901-10024-RFX in all applications?

A: Direct replacement is possible when application requirements align with the substitute part's specifications. The 250 V voltage rating of the substitute part must not exceed application voltage specifications. Cable group compatibility must be verified: the substitute part supports RG-188DS and 316DS, while the main part supports RG-179, 188, 316 double braid, and M17/152-RD316. Termination method flexibility in the substitute part (crimp or solder) accommodates both assembly approaches.

Q: What is the significance of the termination method difference between these parts?

A: The Amphenol RF 901-10024-RFX specifies solder termination for the center contact, requiring soldering equipment and processes. The Cinch Connectivity Solutions Johnson 142-0404-016 offers crimp or solder termination, providing assembly methodology flexibility. Selection depends on manufacturing capabilities, assembly process requirements, and design specifications.

Q: Are there differences in the included components between these parts?

A: Yes. The Amphenol RF 901-10024-RFX includes 4 pieces: connector, contact, ferrule, and heat shrink. The Cinch Connectivity Solutions Johnson 142-0404-016 includes 3 pieces: connector, contact, and sleeve. Assembly requirements and cable preparation procedures may differ based on these component variations.

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

A: Both parts are ROHS3 compliant and REACH affected. Both are classified under EAR99 export control. Both have MSL rating of 1 (Unlimited). Regulatory and compliance profiles are equivalent.

Q: What cable groups are compatible with each part?

A: The Amphenol RF 901-10024-RFX is compatible with RG-179, 188, 316 double braid, and M17/152-RD316 cable groups. The Cinch Connectivity Solutions Johnson 142-0404-016 is compatible with RG-188DS and 316DS cable groups. Cable selection must align with the chosen connector part number.

Q: Is the voltage rating difference a critical factor in part selection?

A: The voltage rating difference is critical only if application specifications require the higher 375 V rating. Applications operating at 250 V or below can utilize either part. Applications requiring voltage ratings above 250 V must use the Amphenol RF 901-10024-RFX.

Q: Do both parts support the same frequency range and impedance?

A: Yes. Both parts operate at 12.4 GHz maximum frequency and maintain 50-ohm impedance. Electrical performance characteristics are equivalent across RF specifications.
