Pomona Electronics 4787 N Type Coaxial Connector Plug - Equivalent & Substitute Parts

Part Overview

The Pomona Electronics 4787 is an N Type connector plug designed for 50 ohm RF coaxial cable applications. This male pin connector features solder termination and is configured as a free hanging (in-line) component suitable for direct cable attachment. The part is currently active in production and maintains ROHS3 compliance with REACH unaffected status, making it suitable for modern electronic assembly requirements.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters including connector style, impedance rating, mounting configuration, and termination method compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 4787 is determined by strict alignment with the following critical parameters:

• Connector Style & Type: Must be N Type plug with male pin configuration
• Impedance Rating: Must maintain 50 ohm impedance
• Mounting Configuration: Must be free hanging (in-line) design
• Termination Compatibility: Contact termination must support solder connection; shield termination must be compatible with clamp-based attachment
• Fastening Method: Must use threaded fastening
• Electrical Properties: Center contact material (brass), plating (gold), and dielectric material (PTFE) must be maintained
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The Amphenol RF 82-5370 qualifies as a substitute part because it maintains all critical parameters while offering extended operational specifications and alternative termination flexibility.

Parameter Comparison

Engineering Selection Recommendations

Both the Pomona Electronics 4787 and Amphenol RF 82-5370 maintain ROHS3 compliance and are suitable for applications requiring N Type 50 ohm coaxial connectors in free hanging configurations.

The Pomona Electronics 4787 is the primary specification part and remains the preferred selection when solder termination with clamp-based shield attachment is the required assembly method.

The Amphenol RF 82-5370 serves as a functional substitute when either of the following conditions apply:

• Assembly processes require crimp termination capability in addition to solder termination
• Applications benefit from extended operational temperature range (-65°C to 165°C) or specified frequency performance (11 GHz maximum)
• Higher mating cycle durability (500 cycles) is required

Both parts are compatible with RG-142 and RG-223 cable groups, providing overlap in typical RF coaxial cable applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 82-5370 be used as a direct replacement for the Pomona Electronics 4787?

A: The Amphenol RF 82-5370 qualifies as a functional substitute for the Pomona Electronics 4787 in applications where the core electrical and mechanical requirements are met. Both parts maintain N Type connector style, 50 ohm impedance, male pin configuration, free hanging mounting, and threaded fastening. The primary difference is termination method flexibility: the 82-5370 supports both crimp and solder termination, while the 4787 is specified for solder only. Assembly process compatibility must be confirmed before substitution.

Q: What are the cable compatibility differences between these parts?

A: The Pomona Electronics 4787 is specified for RG-58, RG-141, RG-142, and RG-223 cable groups. The Amphenol RF 82-5370 is specified for RG-55, RG-142, RG-223, and RG-400 cable groups. Both parts share compatibility with RG-142 and RG-223 cables. Application-specific cable selection must be confirmed based on system impedance and frequency requirements.

Q: Are there packaging or quantity differences between these parts?

A: Both parts are supplied in bulk packaging. The Pomona Electronics 4787 includes 6 pieces per connector unit (connector, braid clamp, clamp, contact, gasket, washer). The Amphenol RF 82-5370 includes 3 pieces per connector unit (connector, contact, ferrule). Assembly kit contents differ and must be verified against assembly requirements.

Q: What compliance certifications apply to both parts?

A: Both the Pomona Electronics 4787 and Amphenol RF 82-5370 maintain ROHS3 compliance. Both are classified under ECCN EAR99 and HTSUS 8536.69.4010. The Pomona Electronics 4787 is specified as REACH Unaffected. REACH status for the Amphenol RF 82-5370 is not provided in the available data and must be confirmed through the manufacturer if required for your application.
