TE Connectivity 647002-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 647002-4 is a 4-position rectangular plug connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and free-hanging or right-angle mounting configuration with latch holder fastening. The part is currently active in production with 679 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector specifications. Alternative models may be required due to inventory availability, packaging preferences, or compliance requirements specific to end-application standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 647002-4 connector is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug)
• Number of positions (4)
• Contact type (Male Pin)
• Pitch spacing (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge compatibility (26 AWG)
• Wire type support (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Latch Holder)
• Closed-end design

Series Designation:

• MTA-100 series membership

The substitute part 3-647002-4 maintains full equivalence across all electrical and mechanical parameters. Variations in contact finish material (tin-lead versus tin) and packaging format (tape and reel versus bulk) do not affect connector interchangeability in standard applications, as these parameters fall outside the core substitution criteria for this product category.

Engineering Selection Recommendations

647002-4 Selection Criteria: The 647002-4 is appropriate for applications where tin-lead contact finish is specified or where RoHS non-compliance is acceptable. This part maintains active production status and is available in standard tape and reel packaging with 679 units in current inventory.

3-647002-4 Selection Criteria: The 3-647002-4 is appropriate for applications requiring RoHS compliance. This substitute part features tin contact finish instead of tin-lead and is supplied in bulk packaging. Inventory availability is higher at 2,447 units. Both parts share identical electrical and mechanical specifications, including connector type, position count, pitch, termination method, wire gauge, and mounting configuration.

Compliance Considerations: Selection between these parts should be based on regulatory requirements specific to the end application. The 3-647002-4 meets RoHS compliance requirements, while the 647002-4 does not. Both parts are classified as REACH Unaffected or Vendor Undefined, indicating no additional REACH substance restrictions apply to standard applications.

Frequently Asked Questions (FAQ)

Q: Are the 647002-4 and 3-647002-4 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 4-position configuration, 0.100" pitch, male pin contact type, IDC termination, and 26 AWG wire gauge compatibility. Electrical performance is equivalent for standard applications.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 647002-4 features tin-lead contact finish, while the 3-647002-4 features tin contact finish. Both finishes are applied at 80.0µin (2.03µm) thickness. Contact finish selection is typically driven by RoHS compliance requirements or specific application standards. Tin-lead finishes are associated with RoHS non-compliance, while tin finishes support RoHS compliance.

Q: Can I use the 3-647002-4 as a direct replacement for the 647002-4?

A: The 3-647002-4 is mechanically and electrically equivalent to the 647002-4 across all core connector parameters. Substitution is valid when RoHS compliance is required or when bulk packaging is preferred. No design modifications are necessary.

Q: What does the packaging difference mean?

A: The 647002-4 is supplied in standard packaging (tape and reel format), while the 3-647002-4 is supplied in bulk packaging. Packaging format does not affect connector performance or compatibility. Selection depends on procurement and assembly process requirements.

Q: Are both parts still in active production?

A: Yes. Both the 647002-4 and 3-647002-4 maintain active product status with TE Connectivity. Current inventory levels are 679 units for the 647002-4 and 2,447 units for the 3-647002-4.

Q: What mounting configurations are supported?

A: Both connectors support free-hanging in-line and right-angle mounting configurations with latch holder fastening. Mounting flexibility is identical between the two parts.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the 647002-4 and 3-647002-4 support discrete or ribbon cable termination via IDC method at 26 AWG wire gauge.
