3M 4650-6005 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 4650-6005 is a 50-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications. This connector features gold-plated male pins rated for 26-28 AWG wire gauges and is configured in a 2-row layout with 0.100" pitch spacing. The product maintains Active status and is ROHS3 compliant, making it suitable for applications requiring reliable inline connectivity with feed-through capability. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate equivalent alternatives.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4650-6005 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Plug with male pin contacts
Position Count & Pitch: 50 positions at 0.100" (2.54mm) pitch
Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
Termination Method: IDC (Insulation Displacement Contact)
Wire Compatibility: 26-28 AWG, supporting both stranded and solid conductors
Contact Material & Finish: Gold plating at 30.0µin (0.76µm) thickness
Mounting Configuration: Free hanging inline orientation
Feed-Through Capability: Required for equivalent substitution
Compliance Status: ROHS3 compliance maintained

The substitute part 4650-6000 meets all these criteria, establishing direct functional and mechanical equivalence with the primary part number.

Engineering Selection Recommendations

Both the 4650-6005 and 4650-6000 are Active products manufactured by 3M within the 4600 series rectangular connector family. Both parts maintain ROHS3 compliance and carry identical EAR99 export classification and HTSUS coding. The parts are mechanically and electrically interchangeable across all specified parameters, including connector geometry, contact configuration, termination method, and wire gauge compatibility.

Selection between these part numbers should be based on inventory availability and lead time requirements. The 4650-6000 currently maintains higher inventory levels (1193 pcs) compared to the 4650-6005 (772 pcs), which may influence procurement decisions for high-volume applications or time-sensitive requirements.

Frequently Asked Questions (FAQ)

Q: Are the 4650-6005 and 4650-6000 mechanically interchangeable?

A: Yes. Both connectors feature identical 50-position, 2-row configurations with 0.100" pitch spacing and row spacing. They share the same free-hanging inline mounting orientation and feed-through capability, ensuring direct mechanical compatibility in existing assemblies.

Q: Can these connectors accept both stranded and solid wire?

A: Yes. Both the 4650-6005 and 4650-6000 are rated for 26-28 AWG wire in either stranded or solid form, providing flexibility in cable selection for IDC termination applications.

Q: What is the significance of the gold contact finish thickness specification?

A: The 30.0µin (0.76µm) gold plating thickness on both parts ensures consistent contact resistance, corrosion resistance, and electrical performance across the 50-position contact array. This specification is identical between the two part numbers.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance status, EAR99 export classification, and HTSUS coding (8536.69.4051). They are equivalent for regulatory and compliance purposes.

Q: What does the feed-through feature provide?

A: The feed-through feature allows signal or power to pass through the connector body, enabling daisy-chain or multi-stage connection configurations in ribbon cable and discrete wire applications.

Q: How does IDC termination differ from other connection methods?

A: IDC (Insulation Displacement Contact) termination pierces the wire insulation without requiring stripping, providing faster assembly and consistent contact pressure across all 50 positions. Both parts employ this termination method.

Q: Can these connectors be used interchangeably in production?

A: Yes. The 4650-6005 and 4650-6000 are direct substitutes with no design or performance differences. They can be used interchangeably in manufacturing, assembly, and field replacement applications without modification to connector interfaces or cable assemblies.
