SBC9209 BNC Connector Plug 75 Ohm Crimp - Equivalent & Substitute Parts

Part Overview

The SBC9209 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 part is classified as Active status and is suitable for RF applications up to 1 GHz. Substitute parts may be required due to inventory availability, supply chain considerations, or specific application requirements where alternative manufacturers' components meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBC9209 is determined by strict equivalence across the following critical parameters:

Mandatory Matching 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
• Number of Ports: 1
• Voltage Rating: 500 V
• Mating Cycles: 500
• Insertion Loss: 0.2 dB

The substitute part 031-71008-1RFX manufactured by Amphenol RF meets all mandatory matching parameters. This part maintains identical electrical performance characteristics and mechanical interface requirements, enabling direct substitution in applications where the SBC9209 is specified.

Engineering Selection Recommendations

SBC9209 (Winchester Interconnect):

• Product Status: Active
• RoHS Compliance: RoHS Compliant
• Current Inventory: 772 Pcs New Original In Stock
• Selection Basis: Primary component with active status and established supply availability

031-71008-1RFX (Amphenol RF):

• Product Status: Not For New Designs
• RoHS Compliance: ROHS3 Compliant
• Current Inventory: 1283 Pcs New Original In Stock
• Selection Basis: Functionally equivalent substitute; however, product status indicates this part is not recommended for new design implementations. Use only when SBC9209 is unavailable or for legacy system maintenance

Both parts satisfy identical electrical and mechanical requirements for 75-ohm BNC plug applications. The 031-71008-1RFX provides higher frequency capability (2 GHz vs. 1 GHz), which does not compromise compatibility with 1 GHz applications. Compliance certifications are equivalent across both parts.

Frequently Asked Questions (FAQ)

Q: Can 031-71008-1RFX be used as a direct replacement for SBC9209?

A: Yes. Both connectors meet identical specifications for connector style, impedance, termination method, mounting configuration, and electrical performance. The 031-71008-1RFX is electrically and mechanically compatible for all applications where SBC9209 is specified.

Q: What is the significance of the "Not For New Designs" status on 031-71008-1RFX?

A: This designation indicates that Amphenol RF does not recommend this part for new product development. For new designs, SBC9209 should be the primary selection. The substitute may be used for replacement, repair, or legacy system support where the original part is unavailable.

Q: Are there packaging differences between these parts?

A: SBC9209 packaging is not specified in available documentation. 031-71008-1RFX is supplied in Bulk packaging and includes 3 pcs per connector unit (1 Connector, 1 Contact, 1 Ferrule). Verify packaging requirements for your application before selection.

Q: Do both parts support the same cable types?

A: SBC9209 is specified for Belden 9209 cable. 031-71008-1RFX supports a broader cable compatibility range including RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, and 9209. Both parts are compatible with Belden 9209 applications.

Q: What is the frequency difference between these parts?

A: SBC9209 operates to 1 GHz maximum frequency. 031-71008-1RFX operates to 2 GHz maximum frequency. For applications operating at or below 1 GHz, both parts perform identically. The higher frequency rating of 031-71008-1RFX does not create incompatibility.

Q: Are compliance certifications equivalent?

A: Both parts are EAR99 classified and carry MSL 1 (Unlimited) ratings. SBC9209 is RoHS Compliant. 031-71008-1RFX is ROHS3 Compliant, which represents a more recent compliance standard. Both meet regulatory requirements for their respective applications.
