TE Connectivity 641436-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641436-4 is a 4-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 787 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across critical parameters including connector type, position count, pitch, cable termination method, wire gauge, and contact configuration. Alternative part numbers may offer different packaging formats, compliance certifications, or contact finish specifications while preserving functional compatibility.

Substitute Part Grouping Explanation

The substitute part 3-641436-4 is functionally equivalent to the main part 641436-4 based on the following critical parameters that determine substitution eligibility:

Electrical Compatibility Parameters:

• Connector type (Plug)
• Number of positions (4)
• Contact type (Male Pin)
• Pitch (0.156" / 3.96mm)
• Cable termination method (IDC)
• Wire gauge (20 AWG)
• Contact finish thickness (80.0µin / 2.03µm)

Mechanical Compatibility Parameters:

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

Differences Between Parts: The substitute part 3-641436-4 differs from 641436-4 in contact finish specification (Tin versus Tin-Lead), packaging format (Bulk versus standard), RoHS compliance status (ROHS3 Compliant versus non-compliant), and HTSUS classification. These differences do not affect electrical or mechanical interchangeability for connector interface applications.

Parameter Comparison

Engineering Selection Recommendations

Part 641436-4 (Tin-Lead Contact Finish): This part is suitable for applications where tin-lead contact finish is specified or required. The part is RoHS non-compliant, making it appropriate for legacy systems, military applications, or designs where RoHS exemptions apply. Current inventory of 787 pieces supports immediate availability for production requirements.

Part 3-641436-4 (Tin Contact Finish): This substitute part is recommended for applications requiring ROHS3 compliance. The tin contact finish meets modern environmental and regulatory standards while maintaining identical electrical and mechanical interface specifications. Higher inventory availability (2375 pieces) supports larger production volumes. The bulk packaging format is suitable for high-volume manufacturing operations.

Selection Criteria:

• Choose 641436-4 when tin-lead contact finish is explicitly required or when RoHS non-compliance is acceptable
• Choose 3-641436-4 when ROHS3 compliance is mandatory or when tin contact finish meets application requirements
• Both parts maintain identical connector interface specifications and are interchangeable at the mechanical and electrical interface level
• Contact finish selection should be based on application requirements, regulatory compliance obligations, and system compatibility specifications

Frequently Asked Questions (FAQ)

Q: Are parts 641436-4 and 3-641436-4 mechanically interchangeable?

A: Yes. Both parts share identical connector type, position count, pitch, contact configuration, and mounting specifications. They interface identically with mating connectors and cable assemblies designed for the MTA-156 series 4-position plug connector.

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

A: The main part 641436-4 features tin-lead contact finish, while substitute part 3-641436-4 features tin contact finish. Both finishes are applied to the same thickness (80.0µin / 2.03µm). The contact finish selection affects RoHS compliance status and may influence application suitability based on regulatory requirements or system specifications.

Q: Does the contact finish difference affect electrical performance?

A: Both tin-lead and tin contact finishes at the specified thickness provide equivalent electrical conductivity and contact resistance characteristics for IDC connector applications. Contact finish selection is driven by compliance requirements and application specifications rather than electrical performance differences.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials including lead. Part 3-641436-4 is ROHS3 compliant, while part 641436-4 is RoHS non-compliant.

Q: Can I use part 3-641436-4 as a direct replacement for 641436-4 in existing designs?

A: Part 3-641436-4 is electrically and mechanically compatible with 641436-4 at the connector interface level. Design compatibility depends on whether the application specifications permit tin contact finish and ROHS3 compliance. Verify that system requirements do not explicitly mandate tin-lead contact finish before substitution.

Q: What is the significance of the packaging difference?

A: Part 641436-4 uses standard packaging, while part 3-641436-4 uses bulk packaging. Bulk packaging is optimized for high-volume manufacturing operations and typically offers cost advantages for large production quantities. Standard packaging is suitable for smaller volumes or mixed-component orders.

Q: Are both parts currently in production?

A: Yes. Both parts maintain active product status with TE Connectivity. Part 641436-4 has 787 pieces in new original inventory, while part 3-641436-4 has 2375 pieces available.

Q: What is IDC termination?

A: IDC (Insulation Displacement Contact) termination is a cable connection method where the connector contacts pierce through the cable insulation to make electrical contact with the conductor. This method eliminates the need for stripping or pre-tinning cable ends and is suitable for both discrete wires and ribbon cables up to 20 AWG.

Q: Can these connectors be used with ribbon cable?

A: Yes. Both parts support discrete or ribbon cable termination at 20 AWG wire gauge, making them suitable for ribbon cable assemblies in addition to individual wire connections.
