3M 4626-6301 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4626-6301 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, feed-through capability, and latch lock/eject hook fastening. The part is Active status and ROHS3 compliant, making it suitable for current production and legacy system maintenance applications. Substitute parts are identified when inventory constraints, supply chain disruptions, or design flexibility requirements necessitate alternative sourcing options that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4626-6301 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Plug with male pin contacts
• Position Count & Pitch: 26 positions at 0.100" (2.54mm) pitch in 2-row configuration
• Termination Method: IDC cable termination supporting 26-28 AWG wire
• Contact Material & Finish: Gold plating at 30.0µin thickness
• Mechanical Compatibility: Free hanging in-line mounting with compatible fastening
• Compliance: ROHS3 compliance and MSL 1 rating

The substitute part 3M 4626-6001 meets all these criteria, differing only in fastening type specification documentation, while maintaining full electrical and mechanical interchangeability for IDC ribbon and discrete cable applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 4626-6301 and 4626-6001 are Active status products from 3M's 4600 series rectangular connector line, ensuring continued manufacturer support and availability. Both parts carry ROHS3 compliance certification and MSL 1 rating, meeting environmental and moisture sensitivity requirements for standard industrial and commercial applications.

Selection between these parts should be based on inventory availability and supply chain considerations. The 4626-6001 currently maintains higher inventory levels (1444 pcs vs. 1023 pcs), making it the preferred choice for high-volume procurement or time-sensitive applications. Both parts are electrically and mechanically equivalent for all IDC ribbon cable and discrete wire termination applications within the specified 26-28 AWG range.

Frequently Asked Questions (FAQ)

Q: Can the 4626-6001 be used as a direct replacement for the 4626-6301 in existing designs?

A: Yes. Both parts are mechanically and electrically identical across all critical parameters including position count, pitch, contact configuration, termination method, and contact finish specifications. No design modifications are required.

Q: Are there any differences in fastening mechanisms between these parts?

A: The 4626-6301 specifies latch lock/eject hooks (long), while the 4626-6001 does not document this specification. However, both parts maintain identical mechanical compatibility and mounting type (free hanging in-line), ensuring interchangeability in applications.

Q: What wire gauges are compatible with both connectors?

A: Both the 4626-6301 and 4626-6001 support 26-28 AWG wire in stranded or solid configuration, with IDC termination method. Wire gauge compatibility is identical between the two parts.

Q: Are both parts suitable for RoHS-regulated applications?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) rating, meeting environmental compliance requirements for regulated industries and applications.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold-plated contacts with 30.0µin (0.76µm) finish thickness, ensuring identical electrical performance and corrosion resistance characteristics.
