3M 4640-7005 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4640-7005 is a 40-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications with wire gauges of 26-28 AWG. This connector features gold-plated contacts and is configured as a free-hanging, in-line plug with a 0.100" (2.54mm) pitch in a 2-row arrangement.

The 4640-7005 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4640-7005 is determined by the following critical parameters:

• Connector Type & Position Count: Must be a plug connector with 40 positions
• Pitch & Row Configuration: Must maintain 0.100" (2.54mm) pitch with 2-row arrangement and 0.100" (2.54mm) row spacing
• Cable Termination Method: Must support IDC termination
• Wire Gauge Compatibility: Must accommodate 26-28 AWG wire, stranded or solid
• Contact Finish: Must feature gold plating at 30.0µin (0.76µm) thickness
• Electrical & Mechanical Compliance: Must meet ROHS3 compliance and MSL 1 rating

The 3M 4640-6000 satisfies all substitution criteria. While the 4640-6000 is classified as active (versus obsolete) and features a feed-through design (versus closed-end), these differences do not affect functional compatibility for IDC-terminated ribbon or discrete cable applications within the specified wire gauge range.

Parameter Comparison

Engineering Selection Recommendations

The 3M 4640-6000 is the direct substitute for the obsolete 4640-7005. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 40-position configuration, 0.100" pitch, 2-row layout, IDC termination capability, 26-28 AWG wire compatibility, and gold contact finish.

The 4640-6000 carries active product status and is ROHS3 compliant with MSL 1 rating, ensuring regulatory compliance and supply chain continuity. The transition from the 4640-7005 to the 4640-6000 presents no functional impedance to existing designs or applications.

Frequently Asked Questions (FAQ)

Q: Can the 4640-6000 directly replace the 4640-7005 in existing assemblies?

A: Yes. Both connectors share identical pitch, position count, row configuration, wire gauge compatibility, and contact finish specifications. The 4640-6000 is functionally equivalent for all IDC-terminated ribbon and discrete cable applications.

Q: What is the difference between the closed-end and feed-through features?

A: The 4640-7005 features a closed-end design, while the 4640-6000 features a feed-through design. This distinction relates to connector housing geometry but does not affect electrical performance or mechanical compatibility with mating connectors or cable termination methods.

Q: Are both connectors RoHS compliant?

A: Yes. Both the 4640-7005 and 4640-6000 are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) ratings.

Q: What wire gauges are supported by the 4640-6000?

A: The 4640-6000 supports 26-28 AWG wire in both stranded and solid configurations, identical to the 4640-7005.

Q: Is the 4640-6000 available in bulk packaging?

A: Yes. The 4640-6000 is available in bulk packaging with current inventory of 1236 pieces in stock.
