3M 4634-6301 Equivalent & Substitute Parts

Part Overview

The 3M 4634-6301 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, feed-through capability, and latch lock/eject hook fastening. The part is currently active in production with 833 units in stock. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

The 3M 4634-6001 is identified as a manufacturer-recommended substitute for the 4634-6301. Substitution eligibility is determined by the following critical parameters:

• Connector Type & Position Count: Both parts are 34-position plugs, ensuring mechanical and electrical compatibility with mating receptacles
• Pitch & Row Configuration: Identical 0.100" (2.54mm) pitch and 2-row spacing guarantee proper alignment and contact engagement
• Cable Termination Method: Both utilize IDC termination for 26-28 AWG wire, maintaining compatibility with existing cable assemblies
• Contact Material & Finish: Gold plating at 30.0µin thickness is consistent across both parts, ensuring equivalent electrical performance and corrosion resistance
• Compliance & Environmental Rating: Both parts meet ROHS3 compliance and carry MSL 1 rating, suitable for identical application environments

The primary difference is the fastening mechanism: the 4634-6301 includes latch lock/eject hooks, while the 4634-6001 does not specify this feature. This distinction does not affect electrical compatibility but may impact mechanical installation preferences.

Parameter Comparison

Engineering Selection Recommendations

Both the 4634-6301 and 4634-6001 are active production parts within the 3M 4600 series, meeting identical ROHS3 compliance and MSL 1 environmental requirements. Selection between these parts should be based on:

• Fastening Mechanism Requirements: The 4634-6301 provides latch lock/eject hooks for positive mechanical retention, while the 4634-6001 omits this feature. Applications requiring positive locking should specify the 4634-6301.
• Inventory Availability: The 4634-6001 maintains higher stock levels (1554 units) compared to the 4634-6301 (833 units), making it suitable for applications where fastening type is not a critical requirement.
• Electrical Equivalence: Both parts deliver identical electrical performance through matching contact finish, pitch, and IDC termination specifications.

Frequently Asked Questions (FAQ)

Q: Can the 4634-6001 directly replace the 4634-6301 in existing assemblies?

A: Electrical and mechanical compatibility is maintained. The primary difference is the absence of latch lock/eject hooks on the 4634-6001. If your application does not require positive mechanical locking, direct substitution is permissible. If latch retention is specified in your design, the 4634-6301 must be used.

Q: Are the contact specifications identical between these two parts?

A: Yes. Both parts feature 34 gold-plated contacts with 30.0µin (0.76µm) finish thickness, 0.100" (2.54mm) pitch, and 2-row configuration. IDC termination for 26-28 AWG wire is identical across both parts.

Q: What is the significance of the fastening type difference?

A: The 4634-6301 includes latch lock/eject hooks for positive mechanical engagement with mating receptacles. The 4634-6001 does not specify this feature. This affects installation method and mechanical retention but does not impact electrical signal integrity.

Q: Are both parts suitable for the same environmental conditions?

A: Yes. Both parts carry MSL 1 (Unlimited) rating and ROHS3 compliance, indicating equivalent suitability for standard industrial and commercial environments without moisture sensitivity constraints.

Q: Can I use ribbon cable with both connectors?

A: Yes. Both the 4634-6301 and 4634-6001 support discrete or ribbon cable termination via IDC contacts, accommodating 26-28 AWG wire in stranded or solid form.
