TE Connectivity 641437-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641437-6 is a 6-position rectangular plug 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 or right-angle mounting configuration. This part is currently active in production with 1005 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector specification. Alternative part numbers may be necessary due to RoHS compliance requirements, packaging format changes, or supply chain considerations while preserving functional compatibility in the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641437-6 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug)
• Number of positions (6)
• Contact type (Male Pin)
• Pitch (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge (22 AWG)
• Contact finish thickness (80.0µin / 2.03µm)

Mechanical Compatibility Parameters:

• Number of rows (1)
• Mounting type (Free Hanging In-Line, Right Angle)
• Features (Closed End)
• Wire type (Discrete or Ribbon Cable)
• Color (Red)
• Series designation (MTA-156)

Environmental & Regulatory Parameters:

• Moisture Sensitivity Level (1 - Unlimited)

The identified substitute part maintains all electrical and mechanical parameters while differing in contact finish composition (tin versus tin-lead) and regulatory compliance status. This variation does not affect functional compatibility in standard applications.

Engineering Selection Recommendations

Part 641437-6 (Tin-Lead Contact Finish):

• Product Status: Active
• RoHS Status: Non-compliant
• REACH Status: Affected
• Application Context: Suitable for applications without RoHS or REACH compliance mandates. Tin-lead contact finish provides established performance characteristics in legacy systems and non-regulated environments.

Part 3-641437-6 (Tin Contact Finish):

• Product Status: Active
• RoHS Status: Compliant
• REACH Status: Unaffected
• Application Context: Required for applications subject to RoHS Directive 2011/65/EU or REACH regulation compliance. Tin contact finish eliminates lead content while maintaining electrical and mechanical compatibility. Higher inventory availability (1436 pieces) supports supply chain continuity.

Both parts maintain identical electrical and mechanical specifications. Selection between these alternatives is determined by regulatory compliance requirements applicable to the end application and target market. Contact finish composition difference does not affect functional performance in standard IDC connector applications.

Frequently Asked Questions (FAQ)

Q: Are the 641437-6 and 3-641437-6 connectors mechanically interchangeable?

A: Yes. Both connectors maintain identical mechanical specifications including 6-position configuration, 0.156" pitch, closed-end design, and free-hanging in-line or right-angle mounting. Physical dimensions and mating interfaces are equivalent.

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

A: Both contact finishes provide equivalent electrical conductivity and contact resistance performance at the specified 80.0µin (2.03µm) thickness. The primary difference is material composition: tin-lead contains lead, while tin does not. This distinction affects regulatory compliance status, not electrical function.

Q: When should I select the 3-641437-6 over the 641437-6?

A: Select the 3-641437-6 when the application or end market requires RoHS Directive compliance or REACH regulation compliance. The 3-641437-6 is RoHS compliant and REACH unaffected, making it suitable for European markets and regulated industries. The 641437-6 remains appropriate for applications without these regulatory requirements.

Q: Are there any performance differences in IDC termination between these two part numbers?

A: No. Both connectors use identical IDC termination technology with 22 AWG wire compatibility. Termination force, contact retention, and cable holding characteristics are equivalent.

Q: What is the significance of the packaging difference between these parts?

A: The 641437-6 packaging format is not specified in the product data. The 3-641437-6 is supplied in bulk packaging. Packaging format affects order quantities, storage requirements, and handling procedures but does not impact connector performance or compatibility.

Q: Can I use these connectors with both discrete and ribbon cable?

A: Yes. Both the 641437-6 and 3-641437-6 support discrete or ribbon cable configurations with 22 AWG wire gauge. IDC termination accommodates both cable types without modification.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean for these connectors?

A: MSL 1 indicates unlimited floor life. These connectors do not require special moisture control during storage, handling, or assembly. No baking or desiccant storage is necessary prior to use.
