N Type Connector Plug 73050 - Equivalent & Substitute Parts

Part Overview

The Pomona Electronics 73050 is an N Type Connector Plug designed for 50 Ohm coaxial cable applications. This male pin connector features push-on contact termination and is rated for operation up to 6 GHz. The component is actively manufactured and maintains full RoHS3 compliance, making it suitable for modern RF and microwave applications requiring reliable coaxial connections in free-hanging inline configurations.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the critical parameters that define connector interchangeability: impedance rating, connector style, contact type, mounting configuration, and cable compatibility specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 73050 is determined by strict alignment with the following core parameters:

Primary Compatibility Criteria:

• Connector Style: N Type (mandatory match)
• Connector Type: Plug, Male Pin (mandatory match)
• Impedance: 50 Ohms (mandatory match)
• Mounting Type: Free Hanging (In-Line) (mandatory match)
• Fastening Type: Threaded (mandatory match)
• Number of Ports: 1 (mandatory match)

Secondary Compatibility Criteria:

• Body Material: Brass
• Body Finish: Nickel
• Center Contact Plating: Gold
• Dielectric Material: PTFE
• Mating Cycles: 500 minimum

The Amphenol RF 082-61 qualifies as a substitute part because it maintains all primary compatibility criteria. Differences in contact termination method (push-on versus crimp), shield termination approach (crimp versus clamp), and cable group specifications do not preclude substitution when the mechanical and electrical interface parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Pomona 73050 and Amphenol RF 082-61 maintain active product status and full ROHS3 compliance. Selection between these parts should be based on application-specific requirements:

The Pomona 73050 employs push-on contact termination, which simplifies field assembly without specialized crimping tools. This configuration is suitable for applications where rapid connector assembly is prioritized.

The Amphenol RF 082-61 utilizes crimp contact termination with clamp-based shield attachment, providing enhanced mechanical retention in high-vibration or demanding environmental conditions. The extended frequency rating to 11 GHz and weatherproof ingress protection rating provide additional performance margin for applications operating near the upper frequency limits of the 50 Ohm N Type connector specification.

Both connectors are compatible with standard N Type mating interfaces and maintain equivalent electrical performance within their respective frequency ratings.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 082-61 be used as a direct replacement for the Pomona 73050?

A: Yes, within the constraints of your assembly process. Both connectors share identical N Type plug geometry, 50 Ohm impedance, and threaded mating interface. The primary difference is termination method: the 73050 uses push-on contacts while the 082-61 requires crimping. Your assembly capability must accommodate the crimp termination process.

Q: What cable types are compatible with each connector?

A: The Pomona 73050 is specified for RG-58 and RG-141 cable groups. The Amphenol RF 082-61 accommodates a broader cable range including RG-8, 8A, 9, 9A, 9B, 87, 213, 214, 225, 302, and 393. Cable compatibility is determined by the connector's internal geometry and contact sizing. Verify your specific cable type against the manufacturer's compatibility matrix before substitution.

Q: Does the higher frequency rating of the 082-61 affect compatibility?

A: No. The 082-61's 11 GHz maximum frequency rating exceeds the 73050's 6 GHz specification. This represents additional performance capability, not a compatibility issue. Both connectors will function correctly in applications operating at or below 6 GHz.

Q: Are there differences in environmental performance between these connectors?

A: The Amphenol RF 082-61 includes weatherproof ingress protection and an operating temperature range of -65°C to 165°C. The Pomona 73050 does not specify these environmental parameters. For applications requiring weatherproof sealing or extended temperature operation, the 082-61 provides documented environmental protection.

Q: What is the significance of the different shield termination methods?

A: The Pomona 73050 uses crimp shield termination; the Amphenol RF 082-61 uses clamp-based termination. Both methods provide equivalent shielding effectiveness when properly executed. Selection depends on your assembly equipment and process capability. Crimp termination requires specialized crimping tools; clamp termination typically uses mechanical fastening.
