TE Connectivity 641435-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641435-4 is a 4-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 obsolete. Due to its obsolete product status and RoHS non-compliance, identification of functionally equivalent active alternatives is necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 641435-4 is based on strict equivalence across the following critical parameters:

• Connector Type & Position Count: Both parts are 4-position rectangular plugs
• Pitch & Row Configuration: Identical 0.156" (3.96mm) pitch with single-row layout
• Contact Type & Termination: Both utilize male pin contacts with IDC cable termination
• Wire Gauge & Cable Compatibility: Both support 18 AWG discrete or ribbon cable
• Mounting Configuration: Both feature free hanging (in-line) and right angle mounting options
• Mechanical Features: Both incorporate closed-end design
• Contact Finish Thickness: Identical 80.0µin (2.03µm) specification

The substitute part 3-641435-4 maintains full mechanical and electrical compatibility with the original 641435-4 while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 3-641435-4 is the direct substitute for the obsolete 641435-4 based on the following engineering criteria:

Product Status: The 3-641435-4 maintains active product status, ensuring continued availability and manufacturer support. The original 641435-4 is classified as obsolete and subject to discontinuation.

Regulatory Compliance: The 3-641435-4 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The 641435-4 is RoHS non-compliant and does not satisfy modern regulatory requirements for new designs or procurement in restricted markets.

Mechanical & Electrical Equivalence: Both connectors share identical specifications across all critical parameters including connector type, position count, pitch, contact configuration, termination method, wire gauge compatibility, and mounting options. The contact finish thickness remains constant at 80.0µin (2.03µm).

Contact Finish Consideration: The substitute part features tin contact finish compared to the original tin-lead finish. Both finishes maintain the specified contact finish thickness and are compatible with IDC termination and 18 AWG wire applications.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Are the 641435-4 and 3-641435-4 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 4-position configuration, 0.156" (3.96mm) pitch, single-row layout, free hanging and right angle mounting options, and closed-end design. They are fully interchangeable in applications requiring these mechanical parameters.

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

A: The original 641435-4 uses tin-lead contact finish, while the substitute 3-641435-4 uses tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm) and are compatible with IDC termination and 18 AWG wire applications. The tin finish in the substitute part reflects current RoHS3 compliance requirements.

Q: Why is the 641435-4 classified as obsolete?

A: The 641435-4 is listed as obsolete by the manufacturer. The active substitute 3-641435-4 provides equivalent functionality with current product status and regulatory compliance.

Q: Can the 3-641435-4 be used in existing designs currently using the 641435-4?

A: Yes. The 3-641435-4 is a direct functional equivalent with identical electrical and mechanical specifications. It is suitable for replacement in existing designs without modification to connector interfaces or cable termination procedures.

Q: What is the significance of RoHS3 compliance for the 3-641435-4?

A: ROHS3 compliance indicates the 3-641435-4 meets current Restriction of Hazardous Substances regulations, making it suitable for procurement in markets with RoHS requirements. The original 641435-4 is RoHS non-compliant and may not be acceptable for new designs or certain geographic markets.

Q: Are both connectors compatible with discrete and ribbon cable?

A: Yes. Both the 641435-4 and 3-641435-4 support discrete or ribbon cable with 18 AWG wire gauge and utilize IDC termination method.

Q: What is the packaging difference between these parts?

A: The original 641435-4 packaging is not specified in available data. The substitute 3-641435-4 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.
