TE Connectivity 647476-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647476-6 is a 6-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for 18 AWG discrete or ribbon cable applications. This connector features gold-plated male pins with 0.156" (3.96mm) pitch spacing and is part of the MTA-156 series.

The 647476-6 carries an obsolete product status. Identification of equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new production applications where this connector type is specified.

Substitute Part Grouping Explanation

Substitution of the 647476-6 is determined by strict equivalence across the following critical parameters:

Connector Type and Position Count: Both the main part and substitute must be 6-position plug connectors to maintain mechanical and electrical compatibility with mating receptacles.
Pitch and Spacing: The 0.156" (3.96mm) pitch is a defining characteristic of the MTA-156 series and must be preserved for proper alignment and contact engagement.
Contact Configuration: Male pin contact type with gold finish ensures electrical performance and corrosion resistance.
Cable Termination Method: IDC termination compatibility is required for applications using discrete or ribbon cable.
Wire Gauge Compatibility: 18 AWG wire gauge specification must be maintained for proper contact retention and electrical conductivity.
Mounting Orientation: Free hanging in-line and right-angle mounting options must be available to support existing application requirements.

The substitute part 3-647476-6 meets all these criteria while offering the advantage of active product status and RoHS compliance.

Engineering Selection Recommendations

The 3-647476-6 is the direct equivalent substitute for the obsolete 647476-6. Both parts are manufactured by TE Connectivity and share identical electrical and mechanical specifications within the MTA-156 series.

Product Status Consideration: The 647476-6 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 3-647476-6 maintains active product status, ensuring ongoing supply chain access and manufacturing support.

Compliance Advantage: The 3-647476-6 is RoHS compliant, whereas the 647476-6 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 3-647476-6 is the appropriate selection.

Functional Equivalence: All critical parameters—connector type, position count, pitch, contact configuration, termination method, and wire gauge—are identical between the two parts. The 3-647476-6 provides direct functional replacement without modification to existing designs or applications.

Packaging: The 3-647476-6 is supplied in bulk packaging, whereas packaging information for the 647476-6 is not specified. Bulk packaging is standard for production and repair applications.

Frequently Asked Questions (FAQ)

Q: Can the 3-647476-6 be used as a direct replacement for the 647476-6 in existing applications?

A: Yes. The 3-647476-6 is functionally equivalent to the 647476-6. Both connectors share identical specifications for connector type, position count, pitch, contact configuration, termination method, and wire gauge. No design modifications are required.

Q: What is the primary difference between the 647476-6 and 3-647476-6?
