TE Connectivity 1-640433-2 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640433-2 is a 12-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete. Due to its obsolete product status, identification of active equivalent parts is necessary to support ongoing maintenance, repair, and new design requirements where this connector type remains functionally appropriate.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640433-2 is determined by strict equivalence across the following critical parameters:

Functional Equivalence Parameters:

• Series designation (MTA-156)
• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (12)
• Pitch specification (0.156" / 3.96mm)
• Number of rows (1)
• Mounting type (Free Hanging In-Line)
• Cable termination method (IDC)
• Wire gauge compatibility (22 AWG)
• Wire type support (Discrete or Ribbon Cable)
• Closed end feature

The substitute part 4-640433-2 maintains identical values across all functional equivalence parameters. The primary difference is the contact finish specification: the substitute uses tin finish rather than tin-lead finish, and carries active product status with RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The 4-640433-2 is the direct active equivalent to the 1-640433-2. Both connectors share identical mechanical and electrical specifications within the MTA-156 series, including pitch, position count, mounting configuration, and IDC termination method for 22 AWG cable.

Compliance Considerations:

The original 1-640433-2 carries RoHS non-compliant status with tin-lead contact finish. The substitute 4-640433-2 is RoHS compliant with tin contact finish. For applications subject to RoHS regulations or requiring compliance with modern environmental standards, the 4-640433-2 is the appropriate selection. The contact finish change from tin-lead to tin does not affect mechanical or electrical compatibility within the MTA-156 connector family.

Product Status:

The 1-640433-2 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 4-640433-2 maintains active product status, ensuring ongoing availability and supply chain support.

Inventory and Availability:

Current inventory of 4-640433-2 (743 pieces) supports immediate procurement for replacement applications.

Frequently Asked Questions (FAQ)

Q: Are the 1-640433-2 and 4-640433-2 mechanically interchangeable?

A: Yes. Both connectors are 12-position receptacles within the MTA-156 series with identical pitch (0.156"), mounting type (free hanging in-line), and closed-end configuration. They are mechanically interchangeable in applications designed for this connector family.

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

A: The 1-640433-2 uses tin-lead finish while the 4-640433-2 uses tin finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin finish in the 4-640433-2 supports RoHS compliance requirements. Electrical performance and contact resistance characteristics remain equivalent within the MTA-156 series specifications.

Q: Can I use the 4-640433-2 as a direct replacement for the 1-640433-2?

A: Yes, the 4-640433-2 is a direct substitute. It supports the same IDC termination method, wire gauge (22 AWG), and cable types (discrete or ribbon cable). The connector will function identically in applications previously using the 1-640433-2.

Q: Why is the 1-640433-2 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by TE Connectivity. The 4-640433-2 represents the active equivalent within the current product line, offering the same functionality with updated compliance certifications.

Q: Does the packaging difference affect compatibility?

A: No. The 1-640433-2 has unspecified packaging while the 4-640433-2 is supplied in bulk packaging. Packaging affects only handling and storage logistics, not connector performance or mechanical fit.

Q: Are both connectors suitable for 22 AWG wire?

A: Yes. Both the 1-640433-2 and 4-640433-2 are rated for 22 AWG wire and support both discrete and ribbon cable termination via IDC method.

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

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