N Type Connector Plug 73052 - Equivalent & Substitute Parts

Part Overview

The Pomona Electronics 73052 is an N Type Connector Plug, Male Pin rated at 50 Ohms for free hanging (in-line) crimp termination applications. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The 73052 operates at frequencies up to 11 GHz and is designed for RG-402 semi-rigid cable applications with a 0.141" diameter specification.

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 73052 is determined by the following mandatory parameters:

Connector Style & Type: N Type Plug, Male Pin configuration
Impedance: 50 Ohms
Contact Termination: Crimp
Mounting Type: Free Hanging (In-Line)
Frequency Rating: 11 GHz maximum
Fastening Type: Threaded
Material Composition: Brass body with PTFE dielectric
Mating Cycles: 500 cycles minimum

Two active Amphenol RF equivalents meet these core substitution criteria: the 082-5375-RFX and 082-61. Both maintain identical connector geometry, electrical ratings, and core material specifications. Differentiation between these substitutes is based on cable group compatibility and shield termination methodology, which determine their application scope within specific cable configurations.

Engineering Selection Recommendations

Both Amphenol RF substitutes (082-5375-RFX and 082-61) are active products with ROHS3 compliance and REACH affected status, providing long-term procurement viability compared to the obsolete Pomona 73052.

Amphenol 082-5375-RFX is suitable for applications utilizing RG-58 series cables, RG-141, RG-303, LMR-195, or equivalent flexible cable configurations. This variant employs crimp shield termination and includes a ferrule component.

Amphenol 082-61 is suitable for applications utilizing larger diameter RG-8 series cables, RG-9 series, RG-213, RG-214, or equivalent cables. This variant employs clamp shield termination, includes a braid clamp and gasket, and provides weatherproof ingress protection.

Selection between these two substitutes is determined by the cable type specified in the original system design. The shield termination method (crimp versus clamp) and included accessory components are engineered for their respective cable group specifications and cannot be interchanged without cable reconfiguration.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol 082-5375-RFX directly replace the Pomona 73052 in all applications?

A: The 082-5375-RFX maintains electrical and mechanical compatibility with the 73052 for applications using RG-58, RG-141, RG-303, LMR-195, or equivalent flexible cables. Cable group compatibility must be verified against the original system specification.

Q: What is the difference between the 082-5375-RFX and 082-61 substitutes?

A: Both are N Type 50 Ohm crimp connectors with identical electrical ratings. The primary differences are cable group compatibility (082-5375-RFX for RG-58 series; 082-61 for RG-8 series), shield termination method (crimp versus clamp), and included accessories. Selection depends on the cable type in your application.

Q: Are both Amphenol substitutes RoHS compliant?

A: Yes, both the 082-5375-RFX and 082-61 are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements.

Q: What is the operational temperature range for the substitute parts?

A: Both Amphenol substitutes operate across -65°C to 165°C, providing extended temperature performance compared to the unspecified range of the original 73052.

Q: Do the substitute connectors support the same frequency range?

A: Yes, both Amphenol substitutes maintain the 11 GHz maximum frequency rating of the original Pomona 73052, ensuring RF performance compatibility in equivalent applications.

Q: What packaging is available for the substitute parts?

A: Both Amphenol substitutes are supplied in bulk packaging with current inventory availability (12,700 pcs for 082-5375-RFX; 1,245 pcs for 082-61).
