Substitute Part Grouping Explanation

The FSNS6U-25 is identified as the manufacturer-recommended substitute for the DB6U-50. Substitution is based on the following critical parameters that remain consistent between both parts:

• Cable Compatibility: Both connectors are designed for RG6 coaxial cable
• Connector Type: Both feature universal F-type termination
• Manufacturer: Both are manufactured by Belden Inc.
• Product Category: Both are classified as Coaxial Connectors (RF)
• Regulatory Compliance: Both maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99)
• Tariff Classification: Both share the same HTSUS code (8536.69.4010)

The primary difference between these parts is packaging quantity (50-pack versus 25-pack) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The FSNS6U-25 is the direct substitute for the DB6U-50 based on manufacturer designation. Both connectors maintain identical regulatory compliance profiles, with REACH Unaffected status and EAR99 ECCN classification, ensuring no additional compliance barriers for substitution. The FSNS6U-25 is currently in active production status, providing assured long-term availability compared to the obsolete DB6U-50. Component selection should prioritize the FSNS6U-25 for new designs and ongoing procurement requirements where RG6 coaxial connector applications are specified.

Frequently Asked Questions (FAQ)

Q: Can the FSNS6U-25 be used as a direct replacement for the DB6U-50?

A: Yes. Both connectors are manufactured by Belden Inc., designed for RG6 cable, feature universal F-type termination, and maintain identical regulatory compliance classifications. The FSNS6U-25 is the manufacturer-recommended substitute.

Q: What is the difference between the DB6U-50 and FSNS6U-25?

A: The primary differences are packaging quantity (50-pack versus 25-pack) and product status (obsolete versus active). The functional connector specifications and electrical/mechanical parameters remain equivalent.

Q: Are there any compliance concerns when substituting the FSNS6U-25 for the DB6U-50?

A: No. Both parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99), eliminating compliance barriers for substitution.

Q: Why is the DB6U-50 obsolete?

A: The DB6U-50 has been discontinued by the manufacturer. The FSNS6U-25 represents the active equivalent product for ongoing sourcing.

Q: Does packaging quantity affect connector performance?

A: No. Packaging quantity (50-pack versus 25-pack) is a supply consideration only and does not affect the electrical or mechanical performance of individual connectors.
