Substitute Part Grouping Explanation

Substitution eligibility for the VB334-75 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Jack, Female Socket
• Impedance: 75 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Through Hole
• Fastening Type: Bayonet Lock
• Frequency - Max: 1 GHz
• Number of Ports: 1
• Operating Temperature Range: -65°C ~ 165°C
• Voltage Rating: 500 V
• Mating Cycles: 500
• Insertion Loss: 0.2 dB
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The VB335-75 meets all mandatory matching parameters and qualifies as a parametric equivalent. Variations in body finish (silver versus tin) do not affect electrical performance or mechanical compatibility within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both VB334-75 and VB335-75 are active products manufactured by Cinch Connectivity Solutions and carry RoHS compliance certification. Selection between these parts is based on procurement availability and inventory status rather than electrical or mechanical performance differences.

The VB334-75 features a silver body finish, while the VB335-75 features a tin body finish. Both finishes are applied to identical brass substrates and do not alter the connector's RF performance, impedance characteristics, or mechanical compatibility within the specified operating temperature range of -65°C to 165°C.

Current inventory levels are 1029 units for VB334-75 and 1184 units for VB335-75, supporting supply chain flexibility for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are VB334-75 and VB335-75 electrically interchangeable?

A: Yes. Both connectors meet identical electrical specifications including 75 ohm impedance, 1 GHz maximum frequency, 500 V voltage rating, 0.2 dB insertion loss, and 500 mating cycles. The difference in body finish does not affect electrical performance.

Q: What is the difference between silver and tin body finishes?

A: The VB334-75 uses a silver body finish while the VB335-75 uses a tin body finish. Both are applied to brass bodies and provide equivalent corrosion resistance and electrical conductivity within the specified operating temperature range of -65°C to 165°C.

Q: Can these connectors be used interchangeably in PCB designs?

A: Yes. Both connectors feature identical through-hole mounting configurations, bayonet lock fastening, and solder termination methods. PCB footprints and assembly processes are compatible between VB334-75 and VB335-75.

Q: Are both parts RoHS compliant?

A: Yes. Both VB334-75 and VB335-75 are RoHS compliant with Moisture Sensitivity Level 1 (Unlimited), supporting compliance requirements for regulated applications.

Q: Which part should be selected for new designs?

A: Selection is based on procurement availability and inventory status. Both parts are active products with equivalent performance. Consult current inventory levels and lead times for procurement decisions.
