3M 4640-6301 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4640-6301 is a 40-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications. This connector features gold-plated contacts rated for 26-28 AWG wire gauges and employs latch lock/eject hook fastening. The part maintains Active product status and is RoHS3 compliant, making it suitable for industrial and commercial applications requiring reliable in-line connectivity.

Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative components that maintain electrical and mechanical compatibility within the 3M 4600 series connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4640-6301 is determined by strict adherence to the following critical parameters:

• Connector Configuration: 40-position plug with 2-row arrangement at 0.100" (2.54mm) pitch and row spacing
• Termination Method: IDC contact technology for 26-28 AWG wire compatibility
• Contact Material: Gold plating at 30.0µin (0.76µm) thickness
• Mounting Orientation: Free hanging in-line configuration
• Compliance: RoHS3 certification and EAR99 export classification

The substitute part 4640-6001 maintains identical electrical and mechanical specifications across all critical parameters. Variations in fastening type designation and moisture sensitivity level do not affect functional interchangeability within the 3M 4600 series connector platform.

Parameter Comparison

Engineering Selection Recommendations

Both the 4640-6301 and 4640-6001 maintain Active product status within the 3M 4600 series connector family, ensuring long-term availability and manufacturing consistency. Both components satisfy RoHS3 compliance requirements and carry identical EAR99 export classification, supporting global supply chain deployment.

Selection between these parts should be based on inventory availability and lead time requirements. The 4640-6001 currently maintains higher stock levels (1427 units) compared to the 4640-6301 (632 units), making it the preferred choice for applications with immediate procurement needs. Both parts are electrically and mechanically interchangeable for 40-position IDC plug connector applications operating within 26-28 AWG wire gauge specifications.

Frequently Asked Questions (FAQ)

Q: Are the 4640-6301 and 4640-6001 electrically interchangeable?

A: Yes. Both connectors feature identical 40-position IDC termination, gold contact finish at 30.0µin thickness, and 26-28 AWG wire gauge compatibility. Electrical performance and signal integrity characteristics are equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are fastening type designation and moisture sensitivity level rating. The 4640-6301 specifies latch lock/eject hooks (long), while the 4640-6001 does not specify fastening type. These variations do not affect mechanical or electrical interchangeability within the 3M 4600 series platform.

Q: Can I use these connectors with both stranded and solid wire?

A: Yes. Both the 4640-6301 and 4640-6001 accommodate 26-28 AWG wire in either stranded or solid configuration through IDC termination technology.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 4640-6301 and 4640-6001 carry RoHS3 compliance certification and are suitable for applications requiring restricted substance compliance.

Q: What is the pitch specification for these connectors?

A: Both connectors feature 0.100" (2.54mm) pitch with 0.100" (2.54mm) row spacing in a 2-row configuration, maintaining standard rectangular connector spacing standards.

Q: Can these connectors be used for ribbon cable applications?

A: Yes. Both the 4640-6301 and 4640-6001 support discrete or ribbon cable termination through IDC contact technology, enabling flexible cable assembly options.
