Pomona Electronics 6718 BNC Connector Jack - Equivalent & Substitute Parts

Part Overview

The Pomona Electronics 6718 is an active BNC connector jack designed for RF coaxial applications requiring 75-ohm impedance. This right-angle, panel-mount through-hole component features solder termination and bayonet locking for secure mating. The connector is suitable for applications operating up to 1 GHz with a rated voltage of 500 V and supports 500 mating cycles. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize procurement costs, and maintain design compatibility across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 6718 is determined by strict adherence to the following critical parameters:

• Connector Style & Type: Must be BNC jack, female socket configuration
• Impedance: Must be 75 ohms
• Mounting Configuration: Must be panel mount, through-hole, right-angle orientation
• Termination Method: Must be solder contact and shield termination
• Fastening Mechanism: Must use bayonet lock
• Electrical Ratings: Must support minimum 1 GHz frequency and 500 V voltage rating
• Port Count: Must have 2 ports
• Mating Cycles: Must support minimum 500 cycles

The Winchester Interconnect 364A2795 meets all these substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Pomona Electronics 6718 and Winchester Interconnect 364A2795 are active products with full regulatory compliance. The Pomona 6718 carries ROHS3 compliance, while the Winchester 364A2795 carries RoHS compliance. Both connectors are classified under identical ECCN and HTSUS codes, confirming their functional equivalence for export and tariff purposes.

The Winchester 364A2795 offers an extended operating temperature range (-55°C to 105°C versus -40°C to 85°C) and includes weatherproof ingress protection, making it suitable for applications requiring enhanced environmental resilience. The Pomona 6718 remains the primary specification when operating temperature constraints fall within -40°C to 85°C and weatherproofing is not required.

Selection between these parts should be based on application-specific environmental requirements and supply chain availability rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the Winchester Interconnect 364A2795 be used as a direct replacement for the Pomona Electronics 6718?

A: Yes. Both connectors share identical BNC jack configuration, 75-ohm impedance, solder termination, bayonet fastening, and electrical ratings (1 GHz maximum frequency, 500 V voltage rating, 500 mating cycles). They are mechanically and electrically interchangeable for standard applications.

Q: What is the primary difference between these two connectors?

A: The Winchester 364A2795 provides an extended operating temperature range (-55°C to 105°C versus -40°C to 85°C) and includes weatherproof ingress protection. The Pomona 6718 operates within a narrower temperature band without weatherproofing features.

Q: Are there packaging differences between these parts?

A: Yes. The Pomona 6718 is supplied in bulk packaging, while the Winchester 364A2795 is supplied in tray packaging. Packaging format does not affect connector performance or compatibility.

Q: Do both connectors meet RoHS requirements?

A: Yes. The Pomona 6718 is ROHS3 compliant, and the Winchester 364A2795 is RoHS compliant. Both meet current environmental and hazardous substance restrictions.

Q: What determines whether a connector can substitute for the Pomona 6718?

A: A substitute connector must maintain identical BNC jack configuration, 75-ohm impedance, panel-mount through-hole right-angle orientation, solder termination, bayonet locking, 1 GHz minimum frequency rating, 500 V voltage rating, and 500 mating cycle minimum. Deviations in any of these parameters disqualify a connector from direct substitution.
