SBC9100 BNC Connector Plug 75 Ohm Crimp - Equivalent & Substitute Parts

Part Overview

The SBC9100 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 free hanging (in-line) mounting configuration and bayonet lock fastening. The part is currently active in production with 1084 pieces in stock inventory. Equivalent and substitute parts are identified when component availability changes, supply chain disruptions occur, or design flexibility permits alternative qualified sources meeting identical or superior electrical and mechanical specifications.

• 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
• Body Material: Brass
• Body Finish: Nickel
• Number of Ports: 1
• RoHS Compliance: Both parts meet RoHS requirements
• MSL Rating: 1 (Unlimited)

The substitute part 112507 is compatible with cable groups including Belden 9100, which is the primary cable group for the SBC9100, confirming mechanical and electrical compatibility for standard RF coaxial applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: SBC9100 (Winchester Interconnect)

The SBC9100 remains the specified component for applications requiring the documented 0.2 dB insertion loss specification and primary compatibility with Belden 9100 cable. This part is active in production with adequate inventory (1084 pieces) and holds RoHS compliance certification.

Substitute Part: 112507 (Amphenol RF)

The 112507 qualifies as a direct substitute when SBC9100 availability is constrained. This part meets or exceeds all critical electrical and mechanical parameters:

• Frequency capability of 4 GHz exceeds the 1 GHz requirement of SBC9100
• Gold-plated center contact provides enhanced corrosion resistance compared to unspecified plating on SBC9100
• Specified dielectric material (POM Acetal) ensures consistent electrical performance
• ROHS3 compliance exceeds RoHS Compliant status
• Broader cable group compatibility (includes Belden 9100 plus additional cable types)
• Higher inventory availability (1484 pieces)

Both parts carry identical voltage rating (500 V), mating cycle rating (500), and MSL rating (1 - Unlimited), confirming suitability for equivalent applications in RF coaxial systems operating at 75 ohm impedance.

Frequently Asked Questions (FAQ)

Q: Can 112507 be used as a direct replacement for SBC9100 in existing designs?

A: Yes. Both connectors share identical BNC plug configuration, 75 ohm impedance, crimp termination, bayonet lock fastening, and voltage/mating cycle ratings. The 112507 meets or exceeds all specified parameters of the SBC9100.

Q: What is the difference in frequency capability between these parts?

A: The SBC9100 is rated to 1 GHz maximum frequency. The 112507 is rated to 4 GHz maximum frequency. For applications operating below 1 GHz, both parts perform equivalently. For applications requiring frequencies between 1 GHz and 4 GHz, only the 112507 is suitable.

Q: Are there packaging differences between SBC9100 and 112507?

A: Yes. The SBC9100 packaging format is not specified in available documentation. The 112507 is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes before substitution.

Q: Does the gold plating on 112507 affect compatibility?

A: No. Gold plating on the center contact of 112507 is a material enhancement that improves corrosion resistance and contact reliability. It does not affect electrical or mechanical compatibility with standard BNC receptacles or mating components.

Q: Which cables are compatible with each connector?

A: The SBC9100 is specified for Belden 9100 cable. The 112507 supports a broader range including RG-59, Belden 1426A, 1505A, 8281, 9100, and 9278. Both connectors are compatible with Belden 9100, confirming interchangeability for this primary cable type.

Q: What is the insertion loss specification for 112507?

A: Insertion loss for 112507 is not provided in available technical documentation. The SBC9100 specifies 0.2 dB insertion loss. For applications with strict insertion loss requirements, verify 112507 performance data with the manufacturer before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The SBC9100 is RoHS Compliant. The 112507 is ROHS3 Compliant, which represents a more current compliance standard. Both parts meet RoHS requirements for lead-free and restricted substance compliance.
