SBC8241F BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The SBC8241F 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 frequencies up to 1 GHz and operates at 500 volts with an insertion loss of 0.2 dB.

The SBC8241F is classified as an active product with 711 units currently in stock. Due to supply chain considerations, design evolution, or application-specific requirements, equivalent substitute parts may be necessary for procurement or design flexibility.

Substitute Part Grouping Explanation

Substitution of the SBC8241F 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
  • Voltage Rating: 500 V
  • Insertion Loss: 0.2 dB
  • Mating Cycles: 500

Allowable Variations:

  • Frequency rating may exceed the minimum requirement (1 GHz)
  • Manufacturer and part number differ
  • Product status may vary
  • Packaging format may differ
  • Compliance certifications may differ

The substitute part 031-71008-1RFX manufactured by Amphenol RF meets all mandatory matching parameters and is therefore electrically and mechanically equivalent to the SBC8241F for 75-ohm coaxial connector applications.

Engineering Selection Recommendations

SBC8241F (Winchester Interconnect):

  • Recommended for new designs and long-term production applications
  • Active product status ensures continued availability and manufacturer support
  • RoHS Compliant certification meets environmental regulatory requirements
  • Suitable for applications requiring 1 GHz maximum frequency operation

031-71008-1RFX (Amphenol RF):

  • Classified as "Not For New Designs," indicating this part is in end-of-life or transition phase
  • ROHS3 Compliant certification provides enhanced environmental compliance
  • Offers higher frequency capability (2 GHz) for applications exceeding 1 GHz requirements
  • Suitable for legacy system maintenance or retrofit applications where Amphenol RF sourcing is established
  • Compatible with multiple cable groups including Belden 8241, 8263, 8279, and 9209

Both parts maintain identical electrical performance at 500 volts, 0.2 dB insertion loss, and 500 mating cycles. Selection between these parts should be based on design phase (new versus legacy), supply chain preferences, and frequency headroom requirements.

Frequently Asked Questions (FAQ)

Q: Can the 031-71008-1RFX substitute for the SBC8241F in existing designs?

A: Yes. Both connectors are electrically and mechanically equivalent for 75-ohm coaxial applications. They share identical impedance, termination methods, voltage rating, insertion loss, and mating cycle specifications. The 031-71008-1RFX provides additional frequency capability (2 GHz versus 1 GHz) without compromising performance at lower frequencies.

Q: What does "Not For New Designs" mean for the 031-71008-1RFX?

A: This product status indicates the part is in end-of-life or transition phase. While the part remains functionally equivalent and available in inventory, the manufacturer recommends using alternative parts for new product development. This part is suitable for maintenance, repair, or retrofit applications.

Q: Are there packaging differences between these parts?

A: Yes. The SBC8241F is supplied in standard packaging, while the 031-71008-1RFX is supplied in bulk packaging. The 031-71008-1RFX includes 3 pieces per connector: 1 connector body, 1 contact, and 1 ferrule. Verify packaging requirements for your assembly process.

Q: Do both parts meet RoHS requirements?

A: Yes. The SBC8241F is RoHS Compliant. The 031-71008-1RFX is ROHS3 Compliant, which represents a more recent version of the RoHS directive. Both parts meet current environmental compliance standards.

Q: What cable types are compatible with these connectors?

A: The SBC8241F is specified for Belden 8241F cable. The 031-71008-1RFX is compatible with a broader range of cables including RG-59, 59B, 62, 140, 210, and Belden 8241, 8263, 8279, and 9209. Verify cable compatibility with your specific application requirements.

Q: Can the 031-71008-1RFX be used in applications requiring 1 GHz operation?

A: Yes. The 031-71008-1RFX is rated for 2 GHz maximum frequency, which exceeds the 1 GHz requirement. It operates within specification at all frequencies up to 2 GHz, including 1 GHz applications.

Q: What is the difference in center contact material between these parts?

A: The SBC8241F center contact material is not specified in the documentation. The 031-71008-1RFX uses brass center contacts with gold plating, providing enhanced corrosion resistance and electrical conductivity.
