3M 4650-6705 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 4650-6705 is a 50-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 rows, and is rated for feed-through applications with latch lock/eject hook fastening.

The 4650-6705 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4650-6705 is determined by the following critical parameters that must remain constant:

• Connector Type & Position Count: Must be a 50-position plug connector
• Pitch & Row Configuration: 0.100" (2.54mm) pitch with 2-row layout and 0.100" row spacing
• Termination Method: IDC cable termination for 26-28 AWG wire (stranded or solid)
• Contact Material & Finish: Gold-plated contacts with 30.0µin (0.76µm) thickness
• Series Compatibility: 3M 4600 series rectangular connectors

The 4650-6000 meets all these substitution criteria and is classified as an active product with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

The 4650-6000 is the direct substitute for the obsolete 4650-6705. Both connectors are identical in electrical and mechanical specifications, including contact configuration, pitch, termination method, and contact finish.

The primary distinction is product status: the 4650-6705 is obsolete, while the 4650-6000 is active and currently manufactured. The 4650-6000 carries RoHS3 compliance and REACH unaffected status, meeting modern regulatory requirements for new designs and production environments.

For applications currently using the 4650-6705, transition to the 4650-6000 ensures continued component availability and compliance with current environmental standards without requiring design modifications.

Frequently Asked Questions (FAQ)

Q: Can the 4650-6000 be used as a direct replacement for the 4650-6705?

A: Yes. Both connectors share identical electrical and mechanical parameters: 50-position plug configuration, 0.100" pitch, 2-row layout, IDC termination for 26-28 AWG wire, and gold contact finish. No design changes are required.

Q: What is the difference between the 4650-6705 and 4650-6000?

A: The 4650-6000 is the active production equivalent. The 4650-6705 is obsolete. The 4650-6000 includes RoHS3 compliance certification, while the 4650-6705 does not list this compliance status.

Q: Are there packaging differences between these parts?

A: The 4650-6705 packaging is not specified in available data. The 4650-6000 is supplied in bulk packaging. Confirm packaging requirements with your procurement department.

Q: What fastening differences exist between these connectors?

A: The 4650-6705 specifies latch lock/eject hooks. The 4650-6000 fastening type is not specified in available data. Verify fastening compatibility with your mating connector before final selection.

Q: Are both connectors suitable for ribbon cable applications?

A: Yes. Both connectors support discrete or ribbon cable with 26-28 AWG wire gauge using IDC termination, and both feature feed-through design.
