3M 4664-6305 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 4664-6305 is a 64-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 0.100" pitch configuration with 2-row layout, and latch lock/eject hook fastening. The part is Active status and ROHS3 compliant, making it suitable for applications requiring reliable inline connectivity with feed-through capability.

Substitute parts are necessary when addressing inventory constraints, lead time requirements, or specific fastening preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4664-6305 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 64 positions, 2-row layout, 0.100" pitch and row spacing
• Electrical Interface: Male pin contact type with IDC cable termination
• Wire Compatibility: 26-28 AWG wire gauge acceptance for both stranded and solid conductors
• Contact Properties: Gold plating with 30.0µin (0.76µm) finish thickness
• Mounting and Mechanical: Free hanging in-line mounting with feed-through capability
• Regulatory Compliance: ROHS3 compliant status

The identified substitute parts (4664-6000 and 4664-6300) maintain full equivalence across all electrical and mechanical parameters. Variations exist only in fastening type specification and moisture sensitivity level designation, which do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—4664-6305, 4664-6000, and 4664-6300—are Active status products with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

Availability and Lead Time: Inventory levels vary across the three parts. The 4664-6300 maintains the highest stock (1262 pcs), followed by 4664-6000 (791 pcs) and 4664-6305 (966 pcs). For time-critical applications, part availability should be the primary selection criterion.

Fastening Specification: The 4664-6305 and 4664-6300 both specify latch lock/eject hooks with long configuration. The 4664-6000 does not specify fastening type. Applications requiring explicit fastening confirmation should prioritize 4664-6305 or 4664-6300.

Moisture Sensitivity: The 4664-6305 lists MSL as Not Applicable. The 4664-6000 specifies MSL 1 (Unlimited). For applications in controlled environments, either part is suitable. The 4664-6300 lists MSL as Not Applicable, matching the main part specification.

All parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance for standard 64-position IDC connector applications.

Frequently Asked Questions (FAQ)

Q: Can 4664-6000 be used as a direct replacement for 4664-6305?

A: Yes. Both parts maintain identical electrical and mechanical specifications across all critical parameters: 64-position configuration, 0.100" pitch, IDC termination, 26-28 AWG wire compatibility, and gold contact finish. The primary difference is fastening type specification, which does not affect functional interchangeability.

Q: What is the significance of the fastening type difference between 4664-6305 and 4664-6000?

A: The 4664-6305 and 4664-6300 explicitly specify latch lock/eject hooks with long configuration. The 4664-6000 does not specify fastening type. For applications where fastening mechanism documentation is required, 4664-6305 or 4664-6300 should be selected.

Q: Are all three parts suitable for ribbon cable applications?

A: Yes. All three parts accept discrete or ribbon cable with 26-28 AWG wire gauge in both stranded and solid configurations. IDC termination is standard across all parts.

Q: Does moisture sensitivity level affect part selection for standard applications?

A: For standard indoor or controlled environment applications, MSL designation does not impact performance. The 4664-6305 and 4664-6300 list MSL as Not Applicable, while 4664-6000 specifies MSL 1 (Unlimited). All parts are suitable for typical connector applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three parts—4664-6305, 4664-6000, and 4664-6300—are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4051) classifications.

Q: What determines whether a part can substitute for 4664-6305?

A: Substitution eligibility is determined by equivalence across connector configuration (64 positions, 2-row, 0.100" pitch), contact type (male pin IDC), wire compatibility (26-28 AWG), contact finish (gold, 30.0µin), and mounting type (free hanging in-line). All identified substitute parts meet these criteria.
