TE Connectivity 647000-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647000-6 is a 6-position rectangular plug connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as an active product. Substitute parts are identified to address specific compliance requirements, inventory availability, and contact finish specifications while maintaining functional equivalence within the MTA-100 connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the TE Connectivity 647000-6 and its equivalent 3-647000-6 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug)
• Number of positions (6)
• Contact type (Male Pin)
• Pitch (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Wire type compatibility (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Latch Holder)
• Features (Closed End)
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Red)
• Series designation (MTA-100)

Environmental Parameters:

• Moisture Sensitivity Level (1 - Unlimited)

The primary distinction between these parts is the contact finish specification: 647000-6 uses tin-lead finish, while 3-647000-6 uses tin finish. Both finishes meet the specified thickness requirement and maintain functional equivalence for IDC connector applications.

Parameter Comparison

Engineering Selection Recommendations

Part 647000-6 (Tin-Lead Finish): This part is classified as RoHS non-compliant and carries undefined REACH status. Selection of this part is appropriate for applications where legacy tin-lead contact finish is specified or where existing inventory compatibility is required. The part maintains active product status and is available in stock.

Part 3-647000-6 (Tin Finish): This part is RoHS Compliant and REACH Unaffected, making it suitable for applications subject to environmental compliance requirements. The tin finish contact maintains the same thickness specification (80.0µin / 2.03µm) as the tin-lead variant. This part is available in significantly higher inventory quantity (12,397 pieces versus 692 pieces) and is the preferred selection for new designs and applications requiring regulatory compliance documentation.

Both parts are functionally equivalent within the MTA-100 series and maintain identical mechanical, electrical, and environmental specifications. Selection between them is determined by compliance requirements and contact finish specifications rather than connector performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 647000-6 and 3-647000-6 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.100" / 2.54mm), number of positions (6), mounting type (Free Hanging In-Line, Right Angle), and fastening type (Latch Holder). They are fully interchangeable in applications where the contact finish specification does not impose constraints.

Q: What is the functional difference between tin-lead and tin contact finishes in these connectors?

A: Both contact finishes are applied at the same thickness (80.0µin / 2.03µm). The primary difference is regulatory compliance: tin-lead finish (647000-6) is RoHS non-compliant, while tin finish (3-647000-6) is RoHS Compliant. For IDC connector applications, both finishes provide equivalent electrical performance and contact reliability.

Q: Can I use the 3-647000-6 as a direct replacement for the 647000-6 in existing designs?

A: The 3-647000-6 is a direct functional substitute for the 647000-6 in all electrical and mechanical aspects. However, design documentation and compliance requirements should be reviewed to confirm that the change from tin-lead to tin finish is acceptable for the specific application.

Q: What does IDC termination mean for these connectors?

A: IDC (Insulation Displacement Contact) termination allows the connector to pierce and grip wire insulation without stripping. Both the 647000-6 and 3-647000-6 support IDC termination with 22 AWG discrete or ribbon cable.

Q: Are these connectors suitable for ribbon cable applications?

A: Yes. Both connectors are specified for discrete or ribbon cable with 22 AWG wire gauge. The IDC termination method is compatible with standard ribbon cable configurations.

Q: What is the significance of the MTA-100 series designation?

A: MTA-100 is the series designation for these rectangular connectors. Both the 647000-6 and 3-647000-6 belong to this series, ensuring compatibility with other MTA-100 series components and accessories.

Q: Why is the inventory quantity significantly different between these two parts?

A: The 3-647000-6 (12,397 pieces) has higher inventory availability than the 647000-6 (692 pieces). This difference reflects market demand patterns and the shift toward RoHS-compliant components in current manufacturing environments.
