3M 4626-7301 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4626-7301 is a 26-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, a closed-end design, and latch lock/eject hook fastening for secure in-line mounting. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, making it suitable for standard industrial and commercial applications requiring reliable signal and power distribution.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the 3M 4600 series, allowing for interchangeability based on specific application requirements and design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3M 4626-7301 are qualified based on strict equivalence of the following critical parameters:

• Number of positions: 26
• Connector type: Plug with male pin contacts
• Pitch and row spacing: 0.100" (2.54mm)
• Cable termination method: IDC
• Wire gauge compatibility: 26-28 AWG, stranded or solid
• Contact finish: Gold at 30.0µin (0.76µm) thickness
• Series membership: 3M 4600 series
• Compliance: ROHS3 compliant, MSL 1 rating
• Product status: Active

The identified substitutes (4626-6001 and 4626-6301) maintain all core electrical and mechanical parameters. Differences exist only in fastening type and end configuration (closed end versus feed through), which are application-specific design choices rather than functional limitations.

Parameter Comparison

Engineering Selection Recommendations

All three parts (4626-7301, 4626-6001, and 4626-6301) maintain Active product status within the 3M 4600 series and satisfy ROHS3 compliance with MSL 1 rating. Selection between these parts depends on application-specific requirements:

The 4626-7301 features a closed-end design with latch lock/eject hook fastening, suitable for applications requiring sealed connector ends and positive mechanical retention.

The 4626-6001 provides a feed-through configuration without specified fastening type, offering flexibility for applications where connector end accessibility is required.

The 4626-6301 combines feed-through end configuration with latch lock/eject hook fastening, providing both end accessibility and positive mechanical retention.

All parts support identical electrical parameters: 26-position IDC termination, gold contact finish at 30.0µin thickness, and 26-28 AWG wire gauge compatibility. Interchangeability is determined by mechanical design requirements rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can 4626-6001 and 4626-6301 be used interchangeably with 4626-7301?

A: Electrical and contact parameters are equivalent across all three parts. Mechanical compatibility depends on application requirements. The 4626-7301 closed-end design differs from the feed-through designs of 4626-6001 and 4626-6301. Verify that the end configuration and fastening type match your application's mechanical constraints before substitution.

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

A: Closed-end connectors (4626-7301) seal the connector end, while feed-through connectors (4626-6001, 4626-6301) allow passage through the connector body. Selection depends on whether your application requires sealed ends or through-connector routing.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts maintain ROHS3 compliance and MSL 1 rating, meeting environmental and moisture sensitivity requirements for standard industrial applications.

Q: What wire gauges are supported by these connectors?

A: All three parts support 26-28 AWG wire, accommodating both stranded and solid conductor types through IDC termination.

Q: Do these connectors require specific fastening procedures?

A: The 4626-7301 and 4626-6301 feature latch lock/eject hook fastening for positive mechanical retention. The 4626-6001 does not specify fastening type. Consult application documentation to confirm fastening compatibility with your mating connector.

Q: What is the contact finish specification?

A: All three parts feature gold-plated contacts with 30.0µin (0.76µm) thickness, providing corrosion resistance and reliable electrical contact across all positions.
