SBC8213 BNC Connector Plug 75 Ohm Equivalent & Substitute Parts

Part Overview

The SBC8213 is a BNC connector plug manufactured by Winchester Interconnect, designed for coaxial RF applications requiring 75 ohm impedance. This male pin connector operates at frequencies up to 1 GHz and features a bayonet lock fastening mechanism for secure mating. The component is actively produced and RoHS compliant, making it suitable for modern electronic assemblies. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBC8213 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

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

Allowable Variations:

• Frequency rating may exceed the original specification (higher frequency capability is backward compatible)
• Contact termination method may differ (crimp vs. other termination types)
• Body finish and plating materials may vary while maintaining electrical performance
• Compliance certifications may differ (RoHS vs. ROHS3)

The substitute part Amphenol RF 112606 meets all mandatory matching parameters and is therefore classified as a direct equivalent for the SBC8213.

Parameter Comparison

Engineering Selection Recommendations

SBC8213 (Winchester Interconnect) is the primary component specification. Selection of this part is appropriate when:

• Original design documentation specifies Winchester Interconnect as the manufacturer
• Existing inventory or supply chain relationships favor this source
• The component is available within required lead times

112606 (Amphenol RF) is a direct substitute meeting all mandatory electrical and mechanical parameters. Selection of this part is appropriate when:

• SBC8213 availability is constrained or discontinued
• Design flexibility permits manufacturer substitution
• The higher frequency capability (4 GHz vs. 1 GHz) provides additional performance margin
• ROHS3 compliance is required in place of RoHS compliance
• Crimp termination is compatible with assembly processes

Both parts are active products with current manufacturing status and full compliance certifications. The 112606 offers extended frequency performance while maintaining identical mechanical and electrical core specifications for 75 ohm BNC plug applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112606 be used as a direct replacement for the Winchester Interconnect SBC8213?

A: Yes. The 112606 meets all mandatory electrical and mechanical parameters: BNC connector style, male pin plug type, 75 ohm impedance, free hanging in-line mounting, bayonet lock fastening, 500 V rating, and 500 mating cycles. The higher frequency rating (4 GHz) is backward compatible with 1 GHz applications.

Q: What is the difference in contact termination between these parts?

A: The SBC8213 termination method is not specified in the component data. The 112606 uses crimp termination for both center contact and shield. Crimp termination is a standard method for BNC connectors and is compatible with standard assembly equipment.

Q: Are there compliance differences between these parts?

A: The SBC8213 carries RoHS compliance certification. The 112606 carries ROHS3 compliance certification. Both certifications indicate lead-free construction and compliance with hazardous substance restrictions. ROHS3 represents an updated compliance framework and is fully compatible with RoHS-compliant applications.

Q: Does the 4 GHz frequency rating of the 112606 affect its use in 1 GHz applications?

A: No. Higher frequency capability is backward compatible. A connector rated for 4 GHz operation functions correctly in applications specified for 1 GHz operation. The extended frequency rating provides additional performance margin without affecting compatibility.

Q: What packaging differences exist between these parts?

A: The SBC8213 packaging is not specified. The 112606 is supplied in bag packaging and includes three pieces per connector: the connector body, one contact, and one ferrule. Verify packaging requirements for your assembly process.

Q: Are the insertion loss specifications comparable?

A: The SBC8213 specifies 0.2 dB insertion loss. The 112606 insertion loss is not provided in the component data. For applications where insertion loss is a critical parameter, direct measurement or manufacturer consultation is required.

Q: Can these connectors be used interchangeably in existing cable assemblies?

A: Yes, provided the cable assembly uses standard BNC jack receptacles. Both the SBC8213 and 112606 are BNC male plugs with bayonet lock fastening and will mate with standard BNC female jacks. Verify that the cable group compatibility (Belden 8213 and related cables) matches your assembly requirements.
