SBC89248 BNC Connector Plug 75 Ohm Crimp - Equivalent & Substitute Parts

Part Overview

The SBC89248 is a BNC connector plug manufactured by Winchester Interconnect, designed for coaxial RF applications requiring 75 ohm impedance. This male pin connector features crimp termination for both center contact and shield, with bayonet lock fastening and free hanging (in-line) mounting configuration. The part is Active status and RoHS Compliant, with 978 pieces currently in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are met, enabling component selection flexibility for procurement, inventory management, or design revision purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SBC89248 are identified based on strict equivalence of the following critical parameters:

Electrical Equivalence Criteria:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 75 Ohms
• Voltage Rating: 500 V
• Mating Cycles: 500

Mechanical Equivalence Criteria:

• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Number of Ports: 1

Compliance Criteria:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• ECCN: EAR99
• HTSUS: 8536.69.4010

The substitute part Amphenol RF 112508 meets all critical electrical and mechanical parameters. Both parts are active status components with equivalent functional performance in 75 ohm coaxial RF applications.

Parameter Comparison

Engineering Selection Recommendations

SBC89248 (Winchester Interconnect) is the primary component specification. Selection of this part is appropriate when:

• Winchester Interconnect supply chain or qualification is required
• Insertion loss specification of 0.2 dB is a documented design requirement
• Existing inventory of 978 pieces supports immediate availability needs

112508 (Amphenol RF) is an equivalent substitute when:

• Amphenol RF supply chain or qualification is established
• The higher maximum frequency rating of 4 GHz provides operational margin beyond the 1 GHz specification of SBC89248
• Inventory availability of 1440 pieces supports procurement requirements
• ROHS3 compliance status meets current regulatory requirements
• Cable group compatibility includes Belden 89248, confirming mechanical and electrical interchangeability

Both parts are Active status components with equivalent 75 ohm BNC plug crimp termination, bayonet lock fastening, and 500 V / 500 cycle ratings. Selection between these parts is based on supply chain, inventory, and manufacturer qualification criteria rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112508 be used as a direct replacement for the Winchester Interconnect SBC89248?

A: Yes. Both parts meet identical electrical and mechanical specifications for 75 ohm BNC plug crimp connectors with bayonet lock fastening and free hanging mounting. All critical parameters including impedance, voltage rating, mating cycles, contact termination, and shield termination are equivalent.

Q: What is the difference between the 1 GHz maximum frequency of SBC89248 and the 4 GHz maximum frequency of 112508?

A: The 112508 has a higher maximum frequency rating, indicating broader operational bandwidth capability. For applications operating at or below 1 GHz, both parts are functionally equivalent. The 112508 provides additional frequency margin for future design flexibility.

Q: Are there packaging differences between these parts?

A: SBC89248 packaging is not specified in the provided data. The 112508 is supplied in Bag packaging and includes 3 pieces per connector: 1 Connector, 1 Contact, and 1 Ferrule. Verify packaging requirements for your assembly process.

Q: What cable types are compatible with the 112508?

A: The 112508 is compatible with RG-6, 6A, 54, 143, 212, Belden 1152A, Belden 89248, and 9290 cable groups. The SBC89248 is specified for Belden 89248 cable group. Confirm cable compatibility with your application requirements.

Q: Are both parts RoHS compliant?

A: Yes. The SBC89248 is RoHS Compliant. The 112508 is ROHS3 Compliant, meeting current regulatory requirements. Both parts carry EAR99 ECCN classification and 8536.69.4010 HTSUS code.

Q: What is the insertion loss specification for the 112508?

A: Insertion loss data is not provided for the 112508 in the available specifications. The SBC89248 specifies 0.2 dB insertion loss. If insertion loss is a critical design parameter, confirm this specification with the manufacturer or use the SBC89248.
