SBC1426A BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The SBC1426A is an active 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 500V operation and supports up to 500 mating cycles. The SBC1426A is specified for use with Belden 1426A cable and operates at frequencies up to 1 GHz with an insertion loss of 0.2dB. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit component flexibility within established electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SBC1426A are identified based on strict equivalence of core electrical and mechanical parameters. The substitution criteria are:

Primary Equivalence 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
• Number of Ports: 1

The Amphenol RF part number 112507 meets all primary equivalence parameters and is therefore classified as a direct substitute. Both connectors are BNC male plug configurations with 75-ohm impedance, crimp termination for center contact and shield, bayonet lock fastening, and identical voltage and mating cycle ratings. Both parts are active products with RoHS compliance and unlimited moisture sensitivity level (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Both the SBC1426A and 112507 are active products with full regulatory compliance. The SBC1426A carries RoHS Compliant certification, while the 112507 carries ROHS3 Compliant certification, indicating enhanced compliance standards for the Amphenol RF part. Both connectors are classified under the same ECCN (EAR99) and HTSUS code (8536.69.4010), confirming equivalent regulatory treatment.

The Amphenol RF 112507 supports a maximum frequency of 4 GHz, which exceeds the SBC1426A specification of 1 GHz. This higher frequency capability does not create incompatibility; rather, it indicates the 112507 is suitable for applications requiring extended frequency performance. The 112507 includes additional documentation specifying compatibility with multiple cable groups (RG-59, Belden 1426A, 1505A, 8281, 9100, 9278), whereas the SBC1426A is specified for Belden 1426A cable.

Both parts maintain identical electrical performance at the specified 75-ohm impedance, 500V voltage rating, and 500 mating cycle endurance. The substitution is valid for applications operating within the SBC1426A frequency range (up to 1 GHz) and for all cable types supported by both connectors.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112507 be used as a direct replacement for the SBC1426A?

A: Yes. Both connectors meet identical specifications for BNC male plug configuration, 75-ohm impedance, crimp termination, bayonet lock fastening, 500V rating, and 500 mating cycles. Both are active products with RoHS compliance and unlimited moisture sensitivity level.

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

A: The SBC1426A is specified for operation up to 1 GHz, while the 112507 is specified for operation up to 4 GHz. The 112507 has extended frequency capability but is fully compatible with applications limited to 1 GHz operation.

Q: Are there differences in cable compatibility?

A: The SBC1426A is specified for Belden 1426A cable. The 112507 is compatible with multiple cable types including RG-59, Belden 1426A, 1505A, 8281, 9100, and 9278. Both connectors are compatible with Belden 1426A cable.

Q: What is the difference in insertion loss between these connectors?

A: The SBC1426A specifies an insertion loss of 0.2dB. Insertion loss data is not provided for the 112507 in the available specifications.

Q: Are both connectors RoHS compliant?

A: Yes. The SBC1426A carries RoHS Compliant certification. The 112507 carries ROHS3 Compliant certification, which represents an enhanced compliance standard. Both meet RoHS requirements.

Q: What packaging is provided for each connector?

A: The SBC1426A packaging type is not specified. The 112507 is supplied in bag packaging and includes 3 pieces per connector: 1 connector, 1 contact, and 1 ferrule.

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

A: Yes, within the electrical and mechanical parameters specified. Both connectors are BNC male plugs with 75-ohm impedance, crimp termination, and identical voltage and mating cycle ratings. The 112507 offers extended frequency capability and broader cable compatibility without compromising performance in applications designed for the SBC1426A.
