TE Connectivity 641436-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641436-6 is a 6-position rectangular plug connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 20 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a closed-end plug with male pin contacts. The part is currently active in production with 634 pieces available in inventory.

Identifying equivalent and substitute parts is necessary when the original part number becomes unavailable, when alternative packaging configurations are required, or when compliance requirements necessitate selection of RoHS-compliant alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641436-6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Plug)
• Number of positions (6)
• Pitch specification (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge (20 AWG)
• Contact type (Male Pin)
• Mounting type (Free Hanging, In-Line, Right Angle)
• Series designation (MTA-156)

Allowable Variations:

• Contact finish composition (Tin-Lead to Tin)
• Packaging configuration (standard to bulk)
• RoHS compliance status

The substitute part 3-641436-6 meets all mandatory matching parameters and represents a direct functional equivalent with modified contact finish and enhanced regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Selection Criteria Based on Regulatory Compliance:

The 641436-6 is classified as RoHS non-compliant, while the substitute part 3-641436-6 achieves ROHS3 compliance. For applications subject to RoHS directives or where end-use regulations mandate lead-free or restricted substance compliance, the 3-641436-6 substitute is the appropriate selection.

Selection Criteria Based on Product Status:

Both parts maintain active production status, ensuring continued availability and supply chain stability. The 3-641436-6 demonstrates significantly higher inventory levels (18094 pieces versus 634 pieces), providing superior supply assurance for high-volume applications.

Selection Criteria Based on Contact Finish:

The primary technical difference between the two parts is the contact finish composition. The main part features tin-lead finish, while the substitute features tin finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm) and are functionally equivalent for IDC termination applications with 20 AWG cable.

Selection Criteria Based on Packaging:

The main part is supplied in standard packaging, while the substitute is supplied in bulk packaging. Bulk packaging is suitable for high-volume manufacturing environments and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the 641436-6 and 3-641436-6 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.156"), number of positions (6), mounting type (Free Hanging, In-Line, Right Angle), and connector geometry. They are mechanically interchangeable in all applications.

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

A: Both contact finishes provide equivalent electrical performance and IDC termination capability. The tin finish in the 3-641436-6 eliminates lead content, enabling ROHS3 compliance. Contact finish thickness remains identical at 80.0µin (2.03µm) for both variants.

Q: Can I use the 3-641436-6 as a direct replacement for the 641436-6?

A: The 3-641436-6 is a direct functional equivalent. Selection depends on regulatory requirements and compliance mandates. For applications requiring RoHS compliance, the 3-641436-6 is the appropriate choice. For applications with no RoHS requirements, either part is suitable.

Q: What does IDC termination mean?

A: IDC (Insulation Displacement Contact) termination is a cable connection method where the connector contacts pierce the insulation of the wire without requiring prior stripping. Both the 641436-6 and 3-641436-6 support IDC termination with 20 AWG discrete or ribbon cable.

Q: Are both parts suitable for ribbon cable applications?

A: Yes. Both connectors support discrete or ribbon cable configurations with 20 AWG wire gauge. The closed-end design accommodates standard ribbon cable widths compatible with 6-position 0.156" pitch spacing.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Why does the 3-641436-6 have significantly higher inventory availability?

A: The 3-641436-6 is supplied in bulk packaging, which is typically ordered in larger quantities for high-volume manufacturing operations. The higher inventory reflects standard bulk distribution practices rather than superior demand.
