Pomona Electronics 6719 BNC Connector Jack - Equivalent & Substitute Parts

Part Overview

The Pomona Electronics 6719 is a BNC connector jack (female socket) rated for 50 ohms impedance, designed for panel mount through-hole applications with right-angle solder termination. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing procurement and system maintenance. The connector features a bayonet lock fastening mechanism and board lock capability, suitable for RF applications up to 4 GHz.

Substitute Part Grouping Explanation

Substitute parts for the Pomona Electronics 6719 are qualified based on the following critical parameters that determine functional equivalence:

Connector style (BNC) and type (Jack, Female Socket)
Impedance rating (50 Ohms)
Mounting configuration (Panel Mount, Through Hole, Right Angle)
Termination method (Solder)
Fastening mechanism (Bayonet Lock)
Frequency capability (minimum 4 GHz)
Voltage rating (minimum 500 V)
Operating temperature range compatibility (-40°C ~ 85°C minimum)

Three substitute parts meet these criteria: Pomona Electronics 6717, Winchester Interconnect 364M2595, and Cinch Connectivity Solutions VBM211C. Each maintains the core electrical and mechanical specifications required for direct substitution in the original application.

Engineering Selection Recommendations

Pomona Electronics 6717 is the primary substitute for the obsolete Pomona 6719. Both parts are manufactured by Pomona Electronics and share identical electrical and mechanical specifications, including 4 GHz frequency capability and ROHS3 compliance. The 6717 is currently in active production status with higher inventory availability (1470 pcs vs. 1146 pcs for the original part).

Winchester Interconnect 364M2595 provides an alternative from a different manufacturer with equivalent core specifications. This part operates at a reduced maximum frequency of 1 GHz, which limits its application to lower-frequency RF systems. The extended operating temperature range (-40°C ~ 165°C) and weatherproof ingress protection offer advantages for harsh environment applications. RoHS compliance is confirmed.

Cinch Connectivity Solutions VBM211C meets all critical substitution parameters with 4 GHz frequency capability matching the original part. This connector includes mounting hardware (lockwasher and nut) as standard inclusions. The extended lower operating temperature limit (-55°C) provides additional thermal margin for cold environment applications. Compliance certifications are not fully specified in available data.

For applications requiring strict frequency performance at 4 GHz, Pomona 6717 or Cinch VBM211C are recommended. For applications operating below 1 GHz with environmental protection requirements, Winchester 364M2595 is suitable.

Frequently Asked Questions (FAQ)

Q: Can the Pomona 6717 directly replace the obsolete 6719 in existing designs?

A: Yes. The Pomona 6717 maintains identical electrical specifications (50 ohms, 4 GHz, 500 V), mechanical configuration (panel mount, through-hole, right-angle), and termination method (solder). Both parts are ROHS3 compliant and rated for the same operating temperature range and mating cycles.

Q: What is the frequency limitation of the Winchester 364M2595?

A: The Winchester 364M2595 is rated to a maximum frequency of 1 GHz, compared to 4 GHz for the Pomona 6719 and 6717. This part is suitable only for applications operating below 1 GHz. For RF systems requiring 4 GHz capability, this substitute is not appropriate.

Q: Does the Cinch VBM211C include mounting hardware?

A: Yes. The Cinch VBM211C is supplied with three components: the connector, one lockwasher, and one nut. This differs from the base connector-only specification of other substitutes and may affect assembly procedures.

Q: Are all substitute parts RoHS compliant?

A: Pomona 6717 and Winchester 364M2595 are confirmed RoHS compliant (ROHS3 and RoHS respectively). Compliance certification for the Cinch VBM211C is not specified in the provided technical data.

Q: What is the difference in packaging between these parts?

A: Pomona 6719 is supplied in unspecified packaging; Pomona 6717 in bulk; Winchester 364M2595 in trays; Cinch VBM211C in bulk. Packaging differences do not affect electrical or mechanical compatibility.

Q: Can these connectors be used interchangeably in the same PCB layout?

A: Yes, provided the application frequency does not exceed the rated maximum of the selected substitute. All four parts share identical mounting configurations (panel mount, through-hole, right-angle) and fastening mechanisms (bayonet lock), allowing direct PCB footprint compatibility.
