Amphenol RF 172270 N Type Coaxial Connector Jack – Equivalent & Substitute Parts

Part Overview

The Amphenol RF 172270 is an N Type connector jack (female socket) rated for 50 ohms impedance, designed for panel mount applications with solder cup termination. This connector operates across a frequency range up to 11 GHz and is suitable for RF/microwave applications requiring bulkhead rear-side nut mounting. The part is Active status and ROHS3 compliant, making it suitable for current production and procurement cycles. Substitute parts are identified to provide alternative sourcing options from RF Industries, maintaining electrical and mechanical compatibility within specified parameter tolerances.

• Impedance: 50 Ohms (identical)
• Contact Termination: Solder Cup (identical)
• Shield Termination: Solder (identical)
• Mounting Type: Panel Mount (identical)
• Mounting Feature: Bulkhead – Rear Side Nut (identical)
• Fastening Type: Threaded (identical)
• Frequency – Max: 11 GHz (identical)
• Number of Ports: 1 (identical)
• Dielectric Material: Polytetrafluoroethylene (PTFE) (identical)
• Center Contact Plating: Gold (identical)
• RoHS Status: ROHS3 Compliant (identical)
• MSL: 1 (Unlimited) (identical)

Substitute parts are sourced from RF Industries and are designated as RFN-1022, RFN-1022-1, RFN-1022-3, and RFN-1022-5. These parts differ in specific material finishes and operating temperature ranges, which are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (RFN-1022, RFN-1022-1, RFN-1022-3, RFN-1022-5) maintain Active product status and ROHS3 compliance, qualifying them for current production applications. The primary electrical parameters—impedance, frequency response, connector type, and termination method—are identical across all parts, ensuring functional interchangeability in RF/microwave circuit applications.

Differences in body finish material (White Bronze versus Silver or Nickel) and center contact material (Phosphor Bronze versus Brass) do not affect electrical performance within the specified frequency and impedance parameters. The RF Industries RFN-1022-5 variant operates within a reduced temperature range (-65°C ~ 85°C) compared to the Amphenol RF 172270 (-65°C ~ 165°C); this variant is suitable for applications not requiring the extended upper temperature limit.

The Amphenol RF 172270 specifies a higher voltage rating (1500 V) and documented insertion loss (0.15 dB) compared to RF Industries substitutes (1000 V, insertion loss not specified). Applications requiring these specific performance metrics should retain the Amphenol RF 172270. For general RF/microwave panel mount applications within the specified frequency and impedance parameters, all substitute parts provide equivalent electrical functionality.

Frequently Asked Questions (FAQ)

Q: Can RF Industries RFN-1022 series parts directly replace the Amphenol RF 172270 in all applications?

A: RF Industries RFN-1022, RFN-1022-1, and RFN-1022-3 are electrically equivalent for RF/microwave applications operating at 50 ohms impedance up to 11 GHz. The RFN-1022-5 variant operates within a reduced temperature range (-65°C ~ 85°C) and is suitable only for applications not requiring operation above 85°C. Applications requiring the full temperature range of the Amphenol RF 172270 (-65°C ~ 165°C) should not use RFN-1022-5.

Q: What are the key differences between the substitute parts?

A: The primary differences are body finish material and operating temperature range. RFN-1022, RFN-1022-1, and RFN-1022-3 feature Silver body finish, while RFN-1022-5 features Nickel body finish. RFN-1022-5 is rated for -65°C ~ 85°C operation, whereas the other variants do not specify operating temperature limits. All variants maintain identical electrical parameters: 50 ohms impedance, N Type connector, female socket, solder cup termination, and 11 GHz maximum frequency.

Q: Does the difference in center contact material (Phosphor Bronze versus Brass) affect performance?

A: The center contact material difference does not affect electrical performance within the specified RF parameters. Both materials provide adequate conductivity and contact reliability for 50 ohm N Type connectors operating up to 11 GHz. The choice between materials is a manufacturing specification that does not impact impedance, frequency response, or insertion loss characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The Amphenol RF 172270 and all RF Industries substitute parts (RFN-1022, RFN-1022-1, RFN-1022-3, RFN-1022-5) are ROHS3 compliant with MSL rating of 1 (Unlimited), qualifying them for current production and procurement cycles.

Q: What is the significance of the voltage rating difference (1500 V versus 1000 V)?

A: The Amphenol RF 172270 is rated for 1500 V, while RF Industries substitutes are rated for 1000 V. Applications requiring high-voltage isolation or operating near the 1500 V specification should retain the Amphenol RF 172270. For standard RF/microwave signal applications, the 1000 V rating of substitute parts is typically sufficient.

Q: Are the packaging and included components identical?

A: The Amphenol RF 172270 includes 3 pieces (1 Connector, 1 Lockwasher, 1 Nut). RF Industries substitute parts do not specify included components. Verify component kit requirements for your application before substitution.

Q: Can RFN-1022-5 be used in applications requiring the full -65°C ~ 165°C temperature range?

A: No. RFN-1022-5 is rated for -65°C ~ 85°C operation only. Applications requiring operation above 85°C must use the Amphenol RF 172270 or RF Industries RFN-1022, RFN-1022-1, or RFN-1022-3 variants.
