Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS-6446-NF-50 is determined by strict equivalence across the following critical parameters:

• Connector type (Jack)
• Contact configuration (6p4c / RJ11, RJ14)
• Mounting method (Through Hole)
• Orientation (90° right-angle)
• Termination method (Solder)
• Shielding type (Unshielded)
• Port and row configuration (1 port, 1 row)
• Board lock feature presence
• Contact material and finish (Copper Alloy, Gold)
• Housing material (Thermoplastic)
• Operating temperature range (-40°C ~ 85°C)

Parts meeting all these criteria are considered direct functional equivalents and may be substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

The SS-6446-NF is the manufacturer-recommended substitute for the obsolete SS-6446-NF-50. Both parts share identical functional and mechanical specifications across all critical parameters required for direct substitution in 6p4c modular jack applications.

The SS-6446-NF offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The part is ROHS3 compliant, meeting current regulatory requirements. Both parts maintain REACH unaffected status and identical export classification (EAR99).

The contact finish thickness differs between the two parts (50.0µin versus 30.0µin), with the substitute featuring a thinner gold plating. This difference does not affect functional compatibility or electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SS-6446-NF directly replace SS-6446-NF-50 in existing designs?

A: Yes. The SS-6446-NF meets all functional and mechanical requirements of the SS-6446-NF-50. No design modifications are required for substitution.

Q: What is the difference in contact finish thickness between these parts?

A: The SS-6446-NF-50 features 50.0µin (1.27µm) gold plating, while the SS-6446-NF features 30.0µin (0.76µm) gold plating. Both thicknesses provide adequate contact durability and electrical performance for the specified application.
