SBC8241B BNC Connector Plug 75 Ohm Crimp

Part Overview

The SBC8241B 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 bayonet lock fastening and free hanging (in-line) mounting configuration. The part is currently active in production status with 755 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design requirements permit compatibility with alternative manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SBC8241B 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

Compatible Substitute Identified:

The part 031-71008-1RFX manufactured by Amphenol RF meets all mandatory matching parameters. This substitute maintains electrical equivalence through identical impedance, termination methods, and performance specifications. The substitute supports extended frequency operation (2 GHz maximum versus 1 GHz for the primary part), which does not restrict compatibility in applications designed for the primary part's frequency range.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (SBC8241B): The SBC8241B is recommended for new designs and ongoing production. This part maintains active product status with established supply availability. RoHS compliance is confirmed, meeting environmental regulatory requirements.

Substitute Part Selection (031-71008-1RFX): The 031-71008-1RFX is electrically and mechanically equivalent and may be used in existing designs where the primary part becomes unavailable. However, this substitute carries "Not For New Designs" status, indicating manufacturer discontinuation trajectory. ROHS3 compliance exceeds baseline RoHS requirements. Selection of this substitute should be limited to legacy system support or temporary supply interruptions of the primary part.

Compliance Considerations: Both parts are RoHS compliant and carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can 031-71008-1RFX be used as a direct replacement for SBC8241B in existing assemblies?

A: Yes. Both connectors share identical electrical specifications (75 ohm impedance, 0.2 dB insertion loss, 500 V rating), mechanical configuration (BNC plug, crimp termination, bayonet lock), and performance characteristics (500 mating cycles). Physical compatibility is confirmed through matching connector style, mounting type, and fastening mechanism.

Q: What is the significance of the "Not For New Designs" status on the substitute part?

A: This designation indicates the manufacturer (Amphenol RF) is not recommending the 031-71008-1RFX for incorporation into new product designs. This reflects anticipated discontinuation. The part remains electrically and mechanically suitable for existing designs but should not be selected for new development programs.

Q: Does the higher frequency rating (2 GHz) of the substitute part affect compatibility?

A: No. The substitute's extended frequency capability (2 GHz maximum versus 1 GHz for the primary part) does not restrict its use in applications designed for the primary part. Higher frequency rating represents enhanced performance margin and does not introduce incompatibility.

Q: Are there packaging differences between these parts?

A: Yes. The SBC8241B packaging is not specified in available documentation. The 031-71008-1RFX is supplied in bulk packaging. Packaging differences do not affect electrical or mechanical compatibility but may impact procurement and inventory handling procedures.

Q: What cable types are compatible with the 031-71008-1RFX?

A: The substitute supports RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, and 9209 cable groups. The primary part is specified for Belden 8241B cable. Belden 8241 compatibility is confirmed for the substitute, ensuring cable interchangeability in existing designs.

Q: Are both parts RoHS compliant?

A: Yes. The SBC8241B is RoHS compliant. The 031-71008-1RFX is ROHS3 compliant, which represents an enhanced compliance standard. Both parts meet RoHS environmental requirements.
