Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Radiall 9101-9573-003 are qualified based on the following critical parameters that must remain constant:

Electrical Compatibility Requirements:

• Connector style: SMA
• Connector type: Plug, Male Pin
• Impedance: 50 Ohms
• Frequency maximum: 12.4 GHz or greater
• Operating temperature range: -65°C ~ 165°C or greater
• Voltage rating: Equal to or greater than 335 V
• Mating cycles: 500 or greater

Mechanical Compatibility Requirements:

• Mounting type: Free Hanging (In-Line)
• Fastening type: Threaded
• Number of ports: 1
• Center contact material: Beryllium Copper
• Center contact plating: Gold
• Body material: Stainless Steel
• Dielectric material: Polytetrafluoroethylene (PTFE)

Termination Consideration: The primary difference between the main part and identified substitutes is the contact termination method. The Radiall 9101-9573-003 uses crimp termination, while substitute parts may employ solder termination. Both termination methods are acceptable for equivalent electrical performance when applied to compatible cable groups.

Parameter Comparison

Engineering Selection Recommendations

Radiall 9101-9573-003 Selection Criteria: The Radiall 9101-9573-003 is the primary choice when crimp termination is specified in the application design. This connector is active in production with established supply availability. The part meets all standard RF coaxial connector requirements for 50-ohm systems operating to 12.4 GHz.

Amphenol RF 901-9601-3SF Selection Criteria: The Amphenol RF 901-9601-3SF serves as an equivalent substitute when solder termination is required or preferred. This part maintains identical electrical performance and mechanical compatibility while offering a higher voltage rating of 375 V compared to the 335 V rating of the Radiall connector. The Amphenol part is RoHS3 compliant and REACH affected, providing additional regulatory compliance documentation. Both parts are classified under the same HTSUS code and ECCN designation, confirming their functional equivalence.

Compliance Status: Both connectors are active products with established production status. The Amphenol RF 901-9601-3SF includes documented RoHS3 compliance and REACH status information, which may be required for specific end-use applications or regional markets.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 901-9601-3SF replace the Radiall 9101-9573-003 in existing designs?

A: The Amphenol RF 901-9601-3SF is electrically and mechanically equivalent to the Radiall 9101-9573-003. The primary difference is the contact termination method: solder versus crimp. Substitution is valid when the application design accommodates solder termination or when solder termination is preferred. Both connectors maintain identical impedance, frequency response, operating temperature range, and mating cycle specifications.

Q: What cable types are compatible with these connectors?

A: The Radiall 9101-9573-003 accommodates RG-174, RG-179, RG-316, M17/113, M17/119, M17/172, and M17/189 cable types. The Amphenol RF 901-9601-3SF is compatible with RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 cables. Cable compatibility should be verified against specific application requirements.

Q: Are there differences in voltage rating between these connectors?

A: Yes. The Radiall 9101-9573-003 has a voltage rating of 335 V, while the Amphenol RF 901-9601-3SF has a voltage rating of 375 V. The Amphenol connector provides a higher voltage margin and is suitable for applications requiring the increased rating.

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

A: Crimp termination (Radiall 9101-9573-003) and solder termination (Amphenol RF 901-9601-3SF) are two distinct assembly methods. Crimp termination uses mechanical pressure to secure the cable to the connector contact. Solder termination uses heat and solder material to create the connection. Both methods produce equivalent electrical performance when properly executed. Selection depends on assembly equipment availability, process capability, and application requirements.

Q: Do these connectors have environmental protection ratings?

A: The Radiall 9101-9573-003 does not specify an ingress protection rating. The Amphenol RF 901-9601-3SF is rated as weatherproof, providing enhanced environmental protection for outdoor or harsh environment applications.

Q: What is the mating cycle specification?

A: Both connectors are rated for 500 mating cycles, indicating the number of times the connector can be mated and unmated while maintaining electrical and mechanical specifications.

Q: Are regulatory compliance documents available for these parts?

A: Both connectors are classified under ECCN EAR99 and HTSUS code 8536.69.4010. The Amphenol RF 901-9601-3SF includes RoHS3 compliance certification and REACH status documentation. The Radiall 9101-9573-003 has a moisture sensitivity level designation of Not Applicable.
