FS6BNCUS Equivalent & Substitute Parts

Part Overview

The FS6BNCUS is a BNC coaxial connector manufactured by Belden Inc., designed for RF applications requiring universal nickel-plated connectivity. This connector is classified as obsolete, necessitating identification of active equivalent parts to maintain supply chain continuity and ensure component availability for ongoing applications. The part is REACH unaffected and carries EAR99 export classification, making it suitable for standard commercial distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Two active substitute parts are identified for the obsolete FS6BNCUS based on shared electrical and mechanical parameters:

Substitution Criteria:

• Coaxial connector category (RF applications)
• BNC connector family
• Nickel plating specification
• REACH unaffected compliance status
• EAR99 export classification
• Identical HTSUS tariff code (8536.69.4010)
• Moisture sensitivity level compatibility

Substitute Parts:

1. 1694ABHD1 – Active BNC connector plug with male pin configuration, 75 Ohms impedance, nickel body finish, and PTFE dielectric
2. FSNS6BNCU-25 – Active universal BNC connector in bulk packaging (25-pack), maintaining Belden manufacturing continuity

Parameter Comparison

Engineering Selection Recommendations

Selection between substitute parts is determined by application requirements and packaging specifications:

1694ABHD1 is suitable for applications requiring individual connector units with specified electrical characteristics. This part provides active product status with defined impedance (75 Ohms), connector type (plug, male pin), and dielectric material (PTFE). The free-hanging mounting configuration and bayonet lock fastening type align with standard BNC connector applications.

FSNS6BNCU-25 maintains direct product line continuity as a universal BNC connector from Belden's active catalog. This part is appropriate for bulk procurement scenarios where 25-unit packaging aligns with supply requirements. The universal designation indicates compatibility across standard BNC applications.

Both substitutes maintain compliance with REACH regulations and EAR99 export classification, ensuring regulatory continuity with the obsolete FS6BNCUS.

Frequently Asked Questions (FAQ)

Q: Why is the FS6BNCUS obsolete? A: The FS6BNCUS has been discontinued by Belden Inc. and is no longer in active production. Substitute parts ensure continued access to equivalent BNC connector functionality.

Q: What are the key compatibility factors between FS6BNCUS and its substitutes? A: Compatibility is based on BNC connector family classification, nickel plating specification, RF coaxial connector category, and shared regulatory compliance (REACH unaffected, EAR99 classification).

Q: What is the difference between 1694ABHD1 and FSNS6BNCU-25? A: 1694ABHD1 is supplied as individual units with specified electrical parameters (75 Ohms impedance, PTFE dielectric). FSNS6BNCU-25 is supplied in bulk packaging (25-pack) and maintains universal BNC connector designation. Selection depends on unit quantity requirements and application specifications.

Q: Are both substitutes manufactured by Belden? A: Yes, both substitute parts are manufactured by Belden or Belden Inc., maintaining supply chain consistency with the original part.

Q: What packaging options are available? A: 1694ABHD1 is available in bulk packaging as individual units. FSNS6BNCU-25 is supplied in 25-unit bulk packs. Selection should align with procurement and inventory management requirements.

Q: Do the substitutes maintain the same regulatory compliance as FS6BNCUS? A: Yes, both substitutes are REACH unaffected and classified as EAR99, matching the regulatory status of the obsolete part.
