Key Parameters

Substitute Part Grouping Explanation

The SS-668804S-A-NF qualifies as a direct substitute for the SS66800-022F based on the following critical parameters:

• Identical connector type, contact configuration (8p8c RJ45), and port count (4)
• Matching orientation (90° right-angle) and mounting method (through-hole solder)
• Equivalent shielding, contact material (copper alloy), and contact finish (gold)
• Identical operating temperature range (-40°C to 85°C)
• Matching mechanical features (board guide, tab direction down)
• Same series designation (Stewart Connector Series 66)

The primary distinction is product status: SS66800-022F is obsolete, while SS-668804S-A-NF is active with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The SS-668804S-A-NF is the designated manufacturer substitute for the obsolete SS66800-022F. Selection of the active part is supported by:

• Identical electrical and mechanical specifications across all functional parameters
• Active product status with confirmed inventory availability (951 pcs in stock)
• ROHS3 compliance certification on the substitute part
• Maintained regulatory compliance (REACH Unaffected, ECCN EAR99)
• Same series lineage and manufacturer support

For applications currently using SS66800-022F, transition to SS-668804S-A-NF requires no design modifications.
