Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 901-9804-1 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector Style: SMA
• Connector Type: Receptacle, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Threaded
• Center Contact Material: Beryllium Copper
• Center Contact Plating: Gold
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Body Material: Stainless Steel
• Number of Ports: 1
• Mating Cycles: 500

The substitute parts identified—Hirose Electric HRM(V)-301S, HRM(V)-304S, and HRM(V)-306S—maintain all critical electrical and mechanical parameters. These parts are functionally equivalent for panel-mount SMA receptacle applications with solder termination and identical impedance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Amphenol RF 901-9804-1 (Primary Selection)

The Amphenol RF 901-9804-1 is the recommended primary selection for new designs. This part maintains Active product status with ROHS3 compliance and provides the widest operating temperature range (-65°C to 165°C), making it suitable for demanding thermal environments. The part is currently in stock with 689 units available.

Hirose Electric HRM(V)-301S (Preferred Substitute)

The Hirose HRM(V)-301S is the preferred substitute option. This part maintains Active product status with ROHS3 compliance, matching the primary part's regulatory standing. It provides higher frequency capability (18 GHz versus 12.4 GHz) and maintains all critical electrical and mechanical parameters. Inventory availability is strong at 1923 units.

Hirose Electric HRM(V)-304S and HRM(V)-306S (Secondary Substitutes)

Both HRM(V)-304S and HRM(V)-306S are classified as Obsolete products. While they maintain electrical and mechanical compatibility with the primary part, their obsolete status limits their suitability for new designs or long-term production requirements. These parts should be considered only when primary and preferred substitute options are unavailable. HRM(V)-306S includes Extended Insulation features matching the primary part.

Regulatory and Compliance Considerations

All parts maintain MSL 1 (Unlimited) moisture sensitivity rating and EAR99 export classification. The primary part and HRM(V)-301S both carry ROHS3 compliance, while the secondary substitutes carry standard RoHS compliance. For applications requiring ROHS3 certification, HRM(V)-301S is the only substitute option.

Frequently Asked Questions (FAQ)

Q: Can the Hirose HRM(V)-301S directly replace the Amphenol RF 901-9804-1?

A: Yes. Both parts maintain identical electrical parameters (50 Ohms impedance, SMA connector style, female socket configuration) and mechanical parameters (panel mount, flange mounting feature, threaded fastening, solder termination). The HRM(V)-301S provides higher frequency capability (18 GHz) and maintains Active product status with ROHS3 compliance.

Q: What is the difference between "Receptacle" and "Jack" terminology in the connector type field?

A: Within the SMA connector family, both terms refer to female socket configurations. The terminology difference reflects manufacturer nomenclature conventions. Electrically and mechanically, these parts are functionally equivalent for mating with standard SMA male connectors.

Q: Why do the Hirose substitutes have a lower maximum operating temperature than the Amphenol part?

A: The Amphenol RF 901-9804-1 operates from -65°C to 165°C, while Hirose parts operate from -55°C to 85°C. This difference reflects design specifications for each manufacturer's product line. For applications requiring the full -65°C to 165°C range, the Amphenol part is the only option among these four parts.

Q: Are the obsolete Hirose parts suitable for production use?

A: The HRM(V)-304S and HRM(V)-306S are classified as Obsolete. While they maintain electrical and mechanical compatibility, obsolete status indicates discontinued manufacturing. These parts should be used only when primary and preferred substitute options are unavailable, and only for applications where long-term supply is not required.

Q: What is the significance of "Extended Insulation" listed for HRM(V)-306S?

A: Extended Insulation is a feature also present on the primary Amphenol RF 901-9804-1 part. The HRM(V)-306S matches this feature specification, while HRM(V)-301S and HRM(V)-304S do not list this feature. For applications requiring Extended Insulation, HRM(V)-306S provides feature parity with the primary part.

Q: Do all these parts share the same packaging specifications?

A: The Amphenol RF 901-9804-1 packaging is listed as unspecified in the provided data. Hirose parts are supplied in Bulk packaging. Packaging specifications should be verified against specific procurement requirements and assembly processes.

Q: What compliance certifications apply to all substitute options?

A: All four parts maintain MSL 1 (Unlimited) moisture sensitivity rating, EAR99 export classification, and REACH Affected status. The Amphenol RF 901-9804-1 and Hirose HRM(V)-301S both carry ROHS3 compliance. The Hirose HRM(V)-304S and HRM(V)-306S carry standard RoHS compliance. For applications requiring ROHS3 certification, only the primary part and HRM(V)-301S are suitable.
