Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0755860103 are identified based on strict equivalence across the following critical parameters:

• Connector type and style (SAS, Mini Receptacle)
• Position count (38 positions)
• Mounting configuration (Surface Mount, Right Angle)
• Termination method (Solder)
• Contact finish specification (Gold, 15.0µin thickness)
• Mechanical features (Board Guide)
• Series designation (iPass PCI Express 75586)
• Compliance certifications (ROHS3, MSL 1)

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

Parameter Comparison
