3M 4634-7201 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4634-7201 is a 34-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications with 26-28 AWG wire gauges. This connector features gold-plated contacts, a gray housing, and latch lock/eject hook fastening. The part is currently obsolete, making identification of active equivalent models essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3M 4634-7201 is determined by strict equivalence across the following critical parameters:

• Connector type (Plug), contact type (Male Pin), and position count (34)
• Pitch and row configuration (0.100" / 2.54mm, 2 rows)
• Cable termination method (IDC)
• Wire gauge compatibility (26-28 AWG)
• Contact finish specification (Gold, 30.0µin thickness)
• Housing color (Gray)
• Compliance certifications (ROHS3, MSL 1)

The substitute parts 4634-6001 and 4634-6201 maintain all critical electrical and mechanical parameters. Differences exist only in fastening type and connector features (feed-through vs. closed-end), which do not affect core substitutability for IDC termination applications.

Parameter Comparison

Engineering Selection Recommendations

Both 4634-6001 and 4634-6201 are active production alternatives to the obsolete 4634-7201. Selection between these substitutes depends on application-specific fastening requirements:

4634-6201 maintains the latch lock/eject hook fastening specification of the original part, making it the preferred direct replacement when fastening type is a design constraint.

4634-6001 omits fastening type specification but is functionally equivalent for IDC termination applications where fastening mechanism is not critical to system performance.

Both substitutes carry identical ROHS3 compliance and MSL 1 ratings, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can 4634-6001 and 4634-6201 be used interchangeably with 4634-7201?

A: Both parts are electrically and mechanically equivalent for IDC termination applications. The primary difference is fastening type: 4634-6201 includes latch lock/eject hooks matching the original design, while 4634-6001 does not specify fastening. Selection depends on whether fastening mechanism is required for your application.

Q: What is the significance of the "Closed End" vs. "Feed Through" feature difference?

A: The closed-end feature of 4634-7201 prevents wire insertion from the rear, while feed-through design in the substitutes allows wire passage. This difference does not affect IDC termination compatibility but may impact mechanical integration in confined spaces.

Q: Are there packaging differences between these parts?

A: The main part (4634-7201) packaging is not specified. Both substitutes are available in bulk packaging, which is standard for production procurement.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory performance.

Q: Why is 4634-7201 listed as obsolete?

A: Product obsolescence typically reflects manufacturing discontinuation. The active substitutes 4634-6001 and 4634-6201 provide continued availability for equivalent connector functionality within the 3M 4600 series.
