3M 4640-7301 Equivalent & Substitute Parts

Part Overview

The 3M 4640-7301 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 male pins rated for 26-28 AWG wire gauges and is configured with a latch lock/eject hook fastening mechanism. The part is Active status and ROHS3 compliant, making it suitable for current production environments. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative connector configurations that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4640-7301 is determined by strict adherence to the following critical parameters:

• Connector Series & Manufacturer: Must be 3M 4600 series to ensure mechanical and electrical compatibility
• Position Count & Configuration: 40 positions, 2-row layout with 0.100" (2.54mm) pitch and row spacing
• Connector Type & Contact Gender: Plug configuration with male pin contacts
• Cable Termination Method: IDC termination for compatibility with ribbon and discrete cable applications
• Wire Gauge Compatibility: 26-28 AWG rated for both stranded and solid wire types
• Contact Finish Specification: Gold plating at 30.0µin (0.76µm) thickness for electrical performance and corrosion resistance
• Compliance & Status: Active product status with ROHS3 compliance

The substitute part 4640-6001 maintains all critical electrical and mechanical parameters. The primary difference is the fastening mechanism: the main part features latch lock/eject hooks, while the substitute features feed-through configuration. Both parts are mechanically and electrically interchangeable within the 3M 4600 series connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the 4640-7301 and 4640-6001 are Active status products with ROHS3 compliance, qualifying them for current production use. Selection between these parts depends on application-specific fastening requirements:

• 4640-7301: Select when latch lock/eject hook fastening and closed-end configuration are required for secure mating and unmating operations
• 4640-6001: Select when feed-through configuration is acceptable and inventory availability or lead time considerations favor this variant

Both parts maintain identical electrical specifications, contact finish, wire gauge compatibility, and IDC termination characteristics. The choice between them is determined by mechanical interface requirements within the connector assembly, not electrical performance.

Frequently Asked Questions (FAQ)

Q: Are 4640-7301 and 4640-6001 electrically interchangeable?

A: Yes. Both connectors feature identical contact finish (gold, 30.0µin thickness), wire gauge ratings (26-28 AWG), and IDC termination. Electrical performance is equivalent.

Q: What is the primary difference between these two parts?

A: The fastening mechanism differs. The 4640-7301 includes latch lock/eject hooks with closed-end configuration, while the 4640-6001 features feed-through configuration without latch mechanisms. Both are mechanically compatible within the 3M 4600 series.

Q: Can I use 4640-6001 as a direct replacement for 4640-7301 in existing designs?

A: Compatibility depends on your mating connector and assembly design. If your design requires latch lock/eject hook engagement, the 4640-6001 feed-through configuration will not provide the same mechanical retention. Verify mating connector compatibility before substitution.

Q: Are both parts suitable for production environments?

A: Yes. Both parts are Active status and ROHS3 compliant, meeting current regulatory and manufacturing standards.

Q: What wire types are compatible with both connectors?

A: Both connectors accept 26-28 AWG wire in stranded or solid configuration via IDC termination.

Q: Do these connectors have moisture sensitivity concerns?

A: No. Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity limitations for storage or handling.
