TE Connectivity 1-640443-0 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640443-0 is a 10-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 28 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 equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640443-0 connector is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (MTA-100)
• Connector type (Receptacle)
• Number of positions (10)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Mounting configuration (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Cable termination method (IDC)
• Wire gauge compatibility (28 AWG)
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Green)
• Base product number (640443)

The substitute part 4-640443-0 maintains full equivalence across all mandatory parameters. The primary distinction between the main part and its substitute is the contact finish composition (tin-lead versus tin) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

The 4-640443-0 serves as the direct substitute for the obsolete 1-640443-0 connector. Both parts are manufactured by TE Connectivity within the MTA-100 series and maintain identical mechanical and electrical specifications across all critical parameters.

Product Status Consideration: The 1-640443-0 is classified as obsolete, while the 4-640443-0 maintains active product status with significantly higher inventory availability (14,489 pieces versus 891 pieces). Selection of the active substitute part ensures long-term component availability and supply chain continuity.

Compliance Consideration: The 4-640443-0 is RoHS compliant, whereas the 1-640443-0 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the substitute part satisfies compliance obligations. The contact finish difference (tin versus tin-lead) reflects this compliance distinction. Both parts maintain identical contact finish thickness specifications and electrical performance characteristics.

Electrical and Mechanical Equivalence: The substitute part maintains full functional equivalence for IDC termination applications with 28 AWG discrete or ribbon cable. Connector geometry, pitch, mounting configuration, and fastening mechanisms are identical between both parts.

Frequently Asked Questions (FAQ)

Q: Can the 4-640443-0 be used as a direct replacement for the 1-640443-0 in existing designs?

A: Yes. The 4-640443-0 is electrically and mechanically equivalent to the 1-640443-0 across all critical parameters including connector type, position count, pitch, mounting configuration, cable termination method, and wire gauge compatibility. Both parts are MTA-100 series receptacles with identical physical dimensions and functional specifications.

Q: What is the difference between the tin-lead finish on the 1-640443-0 and the tin finish on the 4-640443-0?

A: The contact finish composition differs between the two parts. The 1-640443-0 uses tin-lead plating, while the 4-640443-0 uses tin plating. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin finish on the 4-640443-0 reflects RoHS compliance requirements. Electrical performance and contact resistance characteristics remain equivalent.

Q: Why is the 1-640443-0 classified as obsolete?

A: The 1-640443-0 is designated as obsolete by TE Connectivity. The 4-640443-0 represents the current active equivalent within the MTA-100 series. For new designs and ongoing production, the active substitute part is the recommended selection.

Q: Are there packaging differences between these parts?

A: The 1-640443-0 is supplied without specified packaging designation, while the 4-640443-0 is supplied in bulk packaging. Both parts are identical in form, fit, and function. Packaging differences do not affect connector performance or compatibility.

Q: What is the inventory status for these parts?

A: The 1-640443-0 has 891 pieces in stock as new original inventory. The 4-640443-0 has 14,489 pieces in stock as new original inventory. The substitute part offers significantly higher availability for immediate procurement.

Q: Are both parts suitable for IDC termination with 28 AWG cable?

A: Yes. Both the 1-640443-0 and 4-640443-0 are designed for IDC termination with 28 AWG discrete or ribbon cable. The IDC contact design, wire gauge specification, and termination method are identical between both parts.

Q: Do these connectors support both in-line and right-angle mounting?

A: Yes. Both parts specify mounting type as free hanging with in-line and right-angle configuration options. The locking ramp fastening type is identical on both connectors.
