Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4650-6700 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Plug connector with male pin contacts
• Position Count & Pitch: 50 positions at 0.100" (2.54mm) pitch in a 2-row configuration
• Termination Method: IDC (Insulation Displacement Contact) technology
• Wire Compatibility: 26-28 AWG wire gauge support for both stranded and solid conductors
• Contact Material & Finish: Gold plating at 30.0µin (0.76µm) thickness
• Mechanical Features: Feed-through capability with gray housing
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The substitute part 3M 4650-6000 meets all these criteria and belongs to the same 4600 series family, ensuring functional and mechanical compatibility.
