Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0553390608 is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug configuration with outer shroud contacts
• Electrical Interface: 60 positions with 0.40mm pitch across 2 rows
• Mounting Technology: Surface mount assembly compatibility
• Contact System: Gold plating at 10.0µin thickness
• Physical Envelope: 4mm mated stacking height and 0.120" height above board
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The substitute part Molex 5010170608 meets all these parameters and is classified as the manufacturer-recommended equivalent for the obsolete 0553390608.
