TE Connectivity 640433-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640433-6 is a 6-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. The connector features tin-lead contact finish, closed-end design, and free-hanging in-line mounting configuration. This part is currently active in production with 963 units in stock.

Substitute parts are identified to address specific compliance requirements, packaging preferences, or inventory availability while maintaining functional and mechanical compatibility within the MTA-156 connector family.

Substitute Part Grouping Explanation

Substitution between the main part (640433-6) and the identified equivalent (3-640433-6) is based on strict parameter matching within the MTA-156 rectangular connector family. Both parts maintain identical specifications across all critical functional and mechanical parameters:

Key Parameters Determining Substitutability:

Connector type (Receptacle)
Number of positions (6)
Pitch spacing (0.156" / 3.96mm)
Contact type (Female Socket)
Cable termination method (IDC)
Wire gauge compatibility (22 AWG)
Wire type support (Discrete or Ribbon Cable)
Mounting configuration (Free Hanging In-Line)
Contact finish thickness (80.0µin / 2.03µm)
Closed-end design
Series designation (MTA-156)
Moisture sensitivity rating (MSL 1)

The primary distinction between these parts is the contact finish specification (tin-lead versus tin) and packaging format, which do not affect mechanical or electrical compatibility within the connector interface.

Engineering Selection Recommendations

640433-6 Selection Criteria:

The 640433-6 is appropriate for applications where tin-lead contact finish is specified or required by design documentation. This part is RoHS non-compliant and suitable for legacy systems or applications without RoHS restrictions. Standard packaging format is available with 963 units in current inventory.

3-640433-6 Selection Criteria:

The 3-640433-6 is the preferred selection for new designs and applications requiring RoHS3 compliance. This part maintains identical mechanical and electrical specifications while providing lead-free contact finish. Bulk packaging format is available with 847 units in current inventory. The substitute part is recommended for applications subject to RoHS regulations or where lead-free components are mandated by procurement specifications.

Both parts are active products with unlimited moisture sensitivity rating (MSL 1) and are suitable for immediate production use.

Frequently Asked Questions (FAQ)

Q: Are 640433-6 and 3-640433-6 mechanically interchangeable?

A: Yes. Both connectors are 6-position MTA-156 series receptacles with identical pitch (0.156"), mounting configuration (free-hanging in-line), and closed-end design. They interface identically with mating connector plugs and cable assemblies.

Q: What is the functional difference between these parts?

A: The primary difference is contact finish specification. The 640433-6 features tin-lead finish, while the 3-640433-6 features tin finish. Both maintain the same contact finish thickness (80.0µin / 2.03µm) and electrical performance characteristics.

Q: Which part should be selected for RoHS-compliant applications?

A: The 3-640433-6 is ROHS3 compliant and is the correct selection for applications requiring RoHS compliance. The 640433-6 is RoHS non-compliant and is restricted to applications without RoHS requirements.

Q: Are there packaging differences between these parts?

A: Yes. The 640433-6 is supplied in standard packaging, while the 3-640433-6 is supplied in bulk packaging. Both formats contain the same connector specification and are suitable for production assembly.

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

A: Yes. Both parts support IDC termination with discrete or ribbon cable at 22 AWG wire gauge. The closed-end design accommodates both cable types.

Q: What is the moisture sensitivity rating for these connectors?

A: Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are both parts currently in production?

A: Yes. Both 640433-6 and 3-640433-6 are active products with current inventory availability (963 and 847 units respectively).
