3M 4624-6301 Rectangular Connector Plug - Equivalent & Substitute Parts

Part Overview

The 3M 4624-6301 is a 24-position rectangular plug connector designed for IDC (Insulation Displacement Contact) termination with 26-28 AWG wire. This connector features gold-plated contacts, dual-row configuration with 0.100" pitch spacing, and latch lock/eject hook fastening. The part is Active status and ROHS3 compliant, making it suitable for applications requiring reliable discrete or ribbon cable connections in industrial and commercial environments. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative connector options that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4624-6301 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Plug with male pin contacts
Position Count & Pitch: 24 positions at 0.100" (2.54mm) pitch in dual-row configuration
Row Spacing: 0.100" (2.54mm) row-to-row spacing
Termination Method: IDC cable termination
Wire Gauge Compatibility: 26-28 AWG, supporting both stranded and solid wire
Contact Material & Finish: Gold plating at 30.0µin (0.76µm) thickness
Mounting & Fastening: Free hanging in-line mounting with compatible fastening mechanisms
Compliance: ROHS3 compliance and MSL 1 rating

The substitute part 3M 4624-6001 maintains full equivalence across all specified parameters, with the exception of fastening type designation, which does not affect electrical or mechanical compatibility in IDC applications.

Engineering Selection Recommendations

Both the 3M 4624-6301 and 3M 4624-6001 are Active status products with ROHS3 compliance and MSL 1 rating, qualifying them for equivalent use in applications requiring 24-position IDC rectangular plug connectors. Selection between these parts should be based on:

Availability: The 4624-6001 maintains higher inventory levels (1216 pcs vs. 837 pcs), providing supply chain flexibility.
Fastening Specification: The 4624-6301 explicitly specifies latch lock/eject hooks with long configuration. The 4624-6001 does not specify fastening type but maintains full mechanical and electrical compatibility within the 3M 4600 series.
Compliance Requirements: Both parts satisfy ROHS3 and MSL 1 requirements for standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 3M 4624-6001 directly replace the 3M 4624-6301 in existing designs?

A: Yes. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 24-position configuration, 0.100" pitch, dual-row layout, IDC termination, 26-28 AWG wire compatibility, and gold contact finish. The parts are mechanically and electrically interchangeable within the 3M 4600 series.

Q: What is the significance of the fastening type difference between these parts?

A: The 4624-6301 specifies latch lock/eject hooks with long configuration, while the 4624-6001 does not specify fastening type. This difference does not affect IDC termination compatibility or electrical performance. Both connectors support free hanging in-line mounting.

Q: Are both parts suitable for ribbon cable applications?

A: Yes. Both the 4624-6301 and 4624-6001 support discrete or ribbon cable termination via IDC contacts, with wire gauge compatibility of 26-28 AWG in stranded or solid configuration.

Q: Do these connectors require special handling or storage conditions?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard component storage practices apply.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant and carry identical compliance certifications (ECCN: EAR99, HTSUS: 8536.69.4051).
