3M 4634-7300 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4634-7300 is a 34-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 hooks for secure mechanical fastening. The part is Active status and ROHS3 compliant, making it suitable for applications requiring reliable inline connectivity with standardized 0.100" (2.54mm) pitch spacing.

Substitute parts are necessary when the original part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from equivalent configurations within the same connector series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4634-7300 is determined by strict equivalence across the following critical parameters:

• Manufacturer: 3M
• Series: 4600
• Connector Type: Plug
• Number of Positions: 34
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Gauge: 26-28 AWG, Stranded or Solid
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Color: Gray
• RoHS Status: ROHS3 Compliant

The substitute parts 4634-6000 and 4634-6300 maintain all critical electrical and mechanical parameters. Variations exist only in fastening type and end-of-line features (closed end versus feed through), which do not affect electrical compatibility or contact performance. Both substitutes are Active status products with equivalent contact specifications and wire termination capabilities.

Parameter Comparison

Engineering Selection Recommendations

All three parts—4634-7300, 4634-6000, and 4634-6300—are Active status products manufactured by 3M within the 4600 series. All are ROHS3 compliant and carry identical export classification (EAR99) and tariff codes (8536.69.4051).

The primary distinction between parts lies in mechanical design features:

• 4634-7300: Closed-end design with latch lock/eject hooks, Long fastening type. MSL rating of 1 (Unlimited).
• 4634-6000: Feed-through design without specified fastening type. REACH Unaffected status noted.
• 4634-6300: Feed-through design with latch lock/eject hooks, Long fastening type. MSL rating Not Applicable.

Selection between these parts depends on application requirements for end-of-line configuration (closed versus feed-through) and mechanical fastening preferences. All three maintain identical electrical performance, contact specifications, and wire termination compatibility for 26-28 AWG discrete or ribbon cable applications.

Frequently Asked Questions (FAQ)

Q: Can 4634-6000 and 4634-6300 be used interchangeably with 4634-7300?

A: Yes, from an electrical and contact performance standpoint. All three parts share identical connector geometry, pitch spacing, contact finish, and IDC termination specifications. The differences are mechanical: fastening type and end-of-line features (closed versus feed-through). Application requirements determine which variant is appropriate.

Q: What is the difference between "Closed End" and "Feed Through" features?

A: Closed-end connectors (4634-7300) terminate the connector body at the end of the pin array. Feed-through connectors (4634-6000, 4634-6300) allow signal or power routing through the connector body. Selection depends on circuit board layout and signal routing requirements.

Q: Are all three parts RoHS compliant?

A: Yes. 4634-7300 and 4634-6000 are ROHS3 Compliant. 4634-6300 is also ROHS3 Compliant. All three meet RoHS3 requirements.

Q: What wire gauges are supported by these connectors?

A: All three parts support 26-28 AWG wire, in both stranded and solid configurations. IDC termination accommodates both discrete individual wires and ribbon cable assemblies.

Q: Does fastening type affect electrical performance?

A: No. Fastening type (latch lock/eject hooks versus unspecified) is a mechanical consideration for connector retention and ease of mating/unmating. It does not affect electrical conductivity, contact resistance, or signal integrity.

Q: What is the pitch spacing, and why is it important?

A: All three parts have 0.100" (2.54mm) pitch spacing in both horizontal and vertical directions (2-row configuration). This standardized spacing ensures mechanical and electrical compatibility with mating receptacles and printed circuit board layouts designed for 0.100" grid spacing.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: 4634-7300 (3600 Pcs), 4634-6000 (1068 Pcs), and 4634-6300 (1375 Pcs). Availability may influence selection when immediate delivery is required.
