VB1094-75 Equivalent & Substitute Parts

Part Overview

The VB1094-75 is a BNC connector jack (female socket) manufactured by Cinch Connectivity Solutions, designed for 75 ohm coaxial applications with panel mount solder cup termination. This connector operates at frequencies up to 1 GHz and is rated for 500V with an operating temperature range of -55°C to 85°C. The part is currently in active production status with 907 units in stock.

Substitute parts are identified when equivalent functional performance can be maintained within the allowed electrical and mechanical parameters for BNC coaxial connector applications. Substitution becomes necessary due to supply constraints, end-of-life status of primary components, or design flexibility requirements.

Key Parameters

Substitute Part Grouping Explanation

The BNC-FBR(41) from Hirose Electric Co Ltd is identified as a parametric equivalent based on the following shared electrical and mechanical characteristics:

Matching Parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Contact Termination: Solder Cup
• Shield Termination: Solder Tag
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Rear Side Nut
• Fastening Type: Bayonet Lock
• Frequency - Max: 1 GHz
• Number of Ports: 1
• Operating Temperature: -55°C ~ 85°C
• RoHS Status: RoHS Compliant

The primary difference is impedance specification: VB1094-75 operates at 75 ohms while BNC-FBR(41) operates at 50 ohms. This impedance difference must be evaluated within the context of the specific application circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

VB1094-75 is the primary specification for 75 ohm BNC jack applications and maintains active production status with full inventory availability. This part is recommended for new designs and applications requiring 75 ohm impedance matching.

BNC-FBR(41) is designated as Last Time Buy status, indicating limited future availability. This part operates at 50 ohm impedance and should only be considered for applications where 50 ohm impedance is acceptable or where the circuit design accommodates impedance variation. The BNC-FBR(41) demonstrates superior mating cycle performance (5000 cycles versus 500 cycles) and uses beryllium copper contact material, which may provide enhanced durability in high-cycle applications.

Both parts are RoHS compliant and suitable for industrial applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can BNC-FBR(41) be used as a direct replacement for VB1094-75?

A: Physical and mechanical compatibility exists between these parts due to matching BNC connector geometry, panel mount configuration, and bayonet fastening. However, the impedance difference (50 ohms versus 75 ohms) must be evaluated within the specific circuit application. Direct substitution is only appropriate when the circuit design accommodates 50 ohm impedance or when impedance matching is not critical to system performance.

Q: What is the significance of the impedance difference?

A: VB1094-75 is specified for 75 ohm systems, commonly used in video and broadcast applications. BNC-FBR(41) is specified for 50 ohm systems, commonly used in RF and microwave applications. Impedance mismatch can result in signal reflections and performance degradation in impedance-critical circuits.

Q: Why is BNC-FBR(41) marked as Last Time Buy?

A: Last Time Buy status indicates that Hirose Electric Co Ltd has announced end-of-production for this part number. Existing inventory may be available, but future procurement cannot be guaranteed. New designs should specify VB1094-75 or identify alternative active production parts.

Q: Are there differences in contact material performance?

A: VB1094-75 uses brass center contacts with gold plating. BNC-FBR(41) uses beryllium copper center contacts with silver plating. Beryllium copper provides higher spring force and contact pressure, potentially improving connection reliability in high-cycle applications. Gold plating on VB1094-75 provides superior corrosion resistance compared to silver plating.

Q: What is the difference in mating cycle ratings?

A: VB1094-75 is rated for 500 mating cycles, while BNC-FBR(41) is rated for 5000 mating cycles. This indicates BNC-FBR(41) is designed for applications requiring frequent connector engagement and disengagement. VB1094-75 is suitable for applications with infrequent mating operations.

Q: Are both parts suitable for the same operating temperature range?

A: Yes, both parts operate across the identical temperature range of -55°C to 85°C, making them compatible for applications requiring extended temperature performance.
