TE Connectivity 641435-3 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641435-3 is a 3-position rectangular plug connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as a free-hanging, in-line or right-angle mounted component with closed-end design. The part is currently active in production with 1,037 pieces available in inventory. Substitute parts are identified to address specific compliance requirements, material specifications, and availability considerations while maintaining functional equivalence within the MTA-156 connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MTA-156 rectangular connector family is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (MTA-156)
• Number of positions (3)
• Connector type (Plug)
• Contact type (Male Pin)
• Pitch specification (0.156" / 3.96mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge compatibility (18 AWG)
• Wire type support (Discrete or Ribbon Cable)
• Mounting configuration (Free Hanging, In-Line, Right Angle)
• Closed-end design feature
• Contact finish thickness (80.0µin / 2.03µm)

The substitute part 3-641435-3 maintains full functional and mechanical compatibility with the main part 641435-3 across all these parameters. The primary distinction between these parts lies in contact finish material composition (tin-lead versus tin) and associated regulatory compliance status (RoHS non-compliant versus RoHS3 compliant).

Parameter Comparison

Engineering Selection Recommendations

Part 641435-3 (Tin-Lead Contact Finish): This part is suitable for applications where tin-lead contact finish is explicitly specified or required by legacy system designs. The part maintains active production status and is RoHS non-compliant, making it appropriate for non-regulated markets or applications with specific tin-lead material requirements.

Part 3-641435-3 (Tin Contact Finish, RoHS3 Compliant): This substitute part is the preferred selection for new designs and applications subject to RoHS3 compliance requirements. The tin contact finish eliminates lead content while maintaining the same contact finish thickness specification. This part carries ROHS3 compliant certification and is recommended for regulated markets, consumer electronics, and applications requiring environmental compliance documentation. The higher inventory level (3,358 pieces) provides improved availability.

Both parts are functionally and mechanically equivalent within the MTA-156 series and support identical electrical performance for 18 AWG IDC termination applications.

Frequently Asked Questions (FAQ)

Q: Are parts 641435-3 and 3-641435-3 mechanically interchangeable?

A: Yes. Both parts are 3-position MTA-156 series rectangular plug connectors with identical pitch (0.156"), mounting configuration, and IDC termination design. They are mechanically interchangeable in all applications supporting 18 AWG discrete or ribbon cable.

Q: What is the functional difference between these two parts?

A: The primary difference is contact finish material. Part 641435-3 uses tin-lead contact finish, while part 3-641435-3 uses tin contact finish. Both maintain the same contact finish thickness (80.0µin / 2.03µm) and electrical performance characteristics.

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

A: Part 3-641435-3 is ROHS3 compliant and is the appropriate selection for applications subject to RoHS regulations. Part 641435-3 is RoHS non-compliant and should not be used in regulated markets without explicit exemption documentation.

Q: Are there any electrical performance differences between these connectors?

A: No. Both parts support identical electrical specifications for 18 AWG IDC termination and are functionally equivalent in electrical performance.

Q: What is the significance of the contact finish thickness specification?

A: Both parts specify 80.0µin (2.03µm) contact finish thickness, ensuring consistent contact resistance, durability, and electrical performance across both part numbers.

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

A: Yes. Both parts support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method at 18 AWG wire gauge.

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

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

Q: Why does part 3-641435-3 have higher inventory availability?

A: Part 3-641435-3 carries 3,358 pieces in stock compared to 1,037 pieces for part 641435-3, reflecting market demand for RoHS3 compliant components in current production environments.
