Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4664-6301 is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Must be a 64-position plug connector
• Pitch & Row Configuration: 0.100" (2.54mm) pitch with 2-row layout and 0.100" row spacing
• Termination Method: IDC cable termination capability
• Wire Gauge Compatibility: Support for 26-28 AWG wire in both stranded and solid forms
• Contact Specifications: Gold plating with 30.0µin (0.76µm) finish thickness
• Mounting & Features: Free hanging in-line mounting with feed-through capability
• Compliance: ROHS3 compliance and MSL 1 rating

The 3M 4664-6001 meets all these criteria and qualifies as a direct substitute for the obsolete 4664-6301.

Parameter Comparison

Engineering Selection Recommendations

The 3M 4664-6001 is the recommended substitute for the obsolete 4664-6301. Both connectors are manufactured by 3M within the same 4600 series and maintain identical electrical and mechanical specifications across all critical parameters.

The 4664-6001 carries an active product status, ensuring ongoing availability and supply chain support. Both parts maintain ROHS3 compliance and MSL 1 ratings, confirming suitability for standard storage and handling conditions without moisture sensitivity constraints.

The transition from 4664-6301 to 4664-6001 requires no design modifications, as all contact configurations, termination methods, wire gauge compatibility, and mounting characteristics remain unchanged.
