Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS71800-005F is determined by strict alignment across the following critical parameters:

• Connector type and contact configuration (8p8c/RJ45 Ethernet jack)
• Mounting method (through-hole solder termination)
• Physical orientation (90° right-angle)
• Shielding specification (shielded)
• Electrical rating (Cat5e)
• Contact material and finish (copper alloy with gold plating at 30.0µin thickness)
• Operating temperature range (-40°C to 85°C)
• Mechanical features (board lock and panel stops)

The substitute part SS-7188S-A-FLS meets all these criteria and is classified as a direct equivalent within the Stewart Connector 71 series.

Parameter Comparison

Engineering Selection Recommendations

The SS-7188S-A-FLS is a direct functional equivalent to the SS71800-005F. Both parts share identical electrical, mechanical, and environmental specifications within the Stewart Connector 71 series. The primary distinction is product lifecycle status: the SS71800-005F is obsolete, while the SS-7188S-A-FLS maintains active production status.

The SS-7188S-A-FLS carries ROHS3 compliance certification, providing enhanced regulatory alignment for new designs and procurement cycles. Both parts meet REACH requirements and carry identical export classification (EAR99). The substitute part is available in tray packaging, supporting standard component handling and assembly workflows.

Selection of the SS-7188S-A-FLS is appropriate for direct replacement applications where the SS71800-005F is no longer procurable, with no design modifications or board-level changes required.
