SBC82259 BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The SBC82259 is a BNC connector plug manufactured by Winchester Interconnect, designed for 75-ohm coaxial cable applications. This male pin connector features crimp termination for both center contact and shield, with a bayonet lock fastening mechanism. The connector is rated for frequencies up to 1 GHz and operates at 500 V with a maximum insertion loss of 0.2 dB. The product is currently active and RoHS compliant, with 704 units in stock. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when procurement requirements necessitate alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBC82259 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 75 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Voltage Rating: 500 V
• Mating Cycles: 500
• Insertion Loss: 0.2 dB
• Number of Ports: 1

The substitute part 031-71008-2000 (Amphenol RF) meets all mandatory matching parameters. This part maintains electrical and mechanical compatibility with the SBC82259 while offering enhanced frequency capability (2 GHz versus 1 GHz) and extended operating temperature range (-65°C to 165°C). Both parts are RoHS compliant and share the same ECCN and HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SBC82259 and 031-71008-2000 are active products with current manufacturing status and full regulatory compliance. The SBC82259 maintains Winchester Interconnect sourcing with 704 units in current inventory. The 031-71008-2000 provides Amphenol RF sourcing with 1,112 units available, offering dual-source capability for supply chain continuity.

The 031-71008-2000 demonstrates enhanced specifications in frequency capability (2 GHz maximum versus 1 GHz) and operating temperature range (-65°C to 165°C versus unspecified for SBC82259). Both parts maintain identical electrical performance at 0.2 dB insertion loss and 500 V rating. The Amphenol RF part includes specified center contact material (Brass with Gold plating) and dielectric material (PTFE), with documented operating temperature limits.

Selection between these parts should be based on manufacturer preference, inventory availability, and application frequency requirements. Both parts satisfy 75-ohm impedance applications with bayonet-lock BNC connectors and crimp termination.

Frequently Asked Questions (FAQ)
