SBC1506A Equivalent & Substitute Parts

Part Overview

The SBC1506A 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 operation up to 1 GHz and is compatible with RG-59 plenum cable assemblies. As an active product with RoHS compliance and weatherproof ingress protection, the SBC1506A serves applications requiring reliable RF signal transmission in standard and plenum-rated installations. Equivalent and substitute parts are identified for applications where alternative manufacturers' components meet the same electrical and mechanical specifications, or where enhanced performance parameters are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SBC1506A are identified based on strict equivalence of core electrical and mechanical parameters. The primary substitution criteria are:

Mandatory Matching Parameters:

• Connector Style: BNC (or BNC, HD variant)
• Connector Type: Plug, Male Pin
• Impedance: 75 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Number of Ports: 1

Compatible Electrical Specifications:

• Voltage Rating: 500 V minimum
• Mating Cycles: 500 minimum
• Insertion Loss: 0.2 dB or lower

Compliance Requirements:

• RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN: EAR99

Substitute parts may exceed the maximum frequency specification of the main part while maintaining all other parameters. Substitute parts may include additional components in packaging (contact and ferrule inclusions) without affecting substitution validity. Substitute parts may feature enhanced materials (such as phosphor bronze center contacts with gold plating or PTFE dielectric) while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

VB10-2031 (Cinch Connectivity Solutions) is a direct functional equivalent to the SBC1506A. Both connectors share identical electrical specifications including 75-ohm impedance, 1 GHz maximum frequency, 500 V voltage rating, and 0.2 dB insertion loss. Both are RoHS compliant with MSL 1 rating. The VB10-2031 includes additional components (contact and ferrule) in its packaging and features enhanced materials with gold-plated center contact and PTFE dielectric. Operating temperature range extends to -65°C to 165°C. This part is suitable for direct substitution in applications requiring standard BNC 75-ohm crimp connectors.

034-1026 (Amphenol RF) is a BNC HD variant that exceeds the frequency specification of the SBC1506A, supporting operation up to 4 GHz while maintaining 75-ohm impedance and crimp termination. This connector is ROHS3 compliant and includes REACH compliance documentation. The 034-1026 features phosphor bronze center contact with gold plating and PTFE dielectric material. This part is suitable for applications requiring enhanced frequency performance or where HD BNC connector compatibility is specified, while maintaining backward compatibility with standard 75-ohm BNC applications up to 1 GHz.

All three connectors are active products with current manufacturing status and established supply availability.
