Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB6U-25 is determined by the following critical parameters:

• Connector Type & Cable Compatibility: RG6 universal F-type connector specification
• Packaging Configuration: 25-pack quantity
• Regulatory Compliance: REACH Unaffected status and EAR99 ECCN classification
• Tariff Classification: HTSUS code 8536.69.4010 alignment

The FSNS6U-25 qualifies as a direct substitute based on identical electrical specifications, matching cable compatibility (RG6 universal), equivalent regulatory status, and identical packaging quantity. Both components share the same HTSUS classification and REACH compliance profile.

Parameter Comparison

Engineering Selection Recommendations

The FSNS6U-25 is the designated manufacturer-recommended substitute for the obsolete DB6U-25. Selection of this substitute is supported by:

• Product Status Alignment: The FSNS6U-25 maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Equivalence: Both components share identical REACH compliance and ECCN classification, eliminating regulatory re-qualification requirements
• Tariff Consistency: Matching HTSUS codes confirm equivalent product classification for import/export and procurement purposes
• Electrical & Mechanical Compatibility: Identical RG6 universal F-type specifications ensure direct form, fit, and function compatibility

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors meet identical electrical and mechanical specifications for RG6 universal F-type applications. The FSNS6U-25 is the manufacturer-recommended substitute and provides equivalent performance characteristics.

Q: What is the primary reason for substitution?

A: The DB6U-25 is classified as obsolete. The FSNS6U-25 is the active production equivalent from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components share identical REACH status (REACH Unaffected) and ECCN classification (EAR99), eliminating the need for additional compliance documentation or re-qualification.

Q: Does packaging differ between the original and substitute?

A: Both are supplied in 25-pack configurations. The FSNS6U-25 is designated as bulk packaging, which is standard for active production inventory.

Q: Are there any electrical performance differences?

A: No. Both components are specified for identical RG6 universal F-type connector applications and share the same HTSUS tariff classification, confirming functional equivalence.
