TE Connectivity 1-640431-0 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-640431-0 is a 10-position rectangular receptacle 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 mounted component with closed-end design. The part is currently active in production with 1065 units in stock.

Substitute parts are identified to address specific application requirements including RoHS compliance status, packaging configurations, and contact finish specifications while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 1-640431-0 and the identified equivalent 4-640431-0 is based on the following critical parameters that remain constant across both components:

Electrical Compatibility Parameters:

• 10-position configuration
• 0.156" (3.96mm) pitch spacing
• Single row layout
• Female socket contact type
• IDC termination technology
• 18 AWG wire gauge specification
• Support for discrete or ribbon cable

Mechanical Compatibility Parameters:

• Free-hanging, in-line mounting orientation
• Closed-end connector design
• Contact finish thickness of 80.0µin (2.03µm)
• Orange color designation
• MTA-156 series classification

Differentiating Parameters:

• Contact finish composition (Tin-Lead vs. Tin)
• RoHS compliance status
• Packaging configuration (standard vs. bulk)
• REACH compliance documentation

The substitute part maintains full electrical and mechanical interchangeability while offering alternative compliance and packaging options.

Parameter Comparison

Engineering Selection Recommendations

Part 1-640431-0 Selection Criteria:

• Applications where tin-lead contact finish is specified or required
• Designs not subject to RoHS compliance mandates
• Standard packaging requirements
• Existing inventory with established supply chain

Part 4-640431-0 Selection Criteria:

• Applications requiring RoHS compliance certification
• New designs targeting regulatory compliance with EU directives
• Bulk packaging configurations for high-volume production
• Tin contact finish specifications

Both parts maintain identical electrical performance, mechanical fit, and termination characteristics. Selection between them is determined by regulatory compliance requirements, contact finish specifications, and packaging needs rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Are these connectors electrically interchangeable? A: Yes. Both the 1-640431-0 and 4-640431-0 maintain identical electrical specifications including 10-position configuration, 0.156" pitch, 18 AWG wire gauge, and IDC termination method.

Q: What is the difference between tin-lead and tin contact finishes? A: The main part features tin-lead contact finish while the substitute features tin contact finish. Both maintain the same 80.0µin (2.03µm) thickness specification. The contact finish difference does not affect mechanical or electrical compatibility.

Q: Can I use the 4-640431-0 in place of the 1-640431-0 in existing designs? A: Yes, provided your application does not specifically require tin-lead contact finish. The 4-640431-0 is mechanically and electrically compatible and offers the additional benefit of RoHS compliance.

Q: What does RoHS compliance mean for connector selection? A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances directives. The 4-640431-0 is RoHS compliant while the 1-640431-0 is not. Selection depends on whether your application or market requires RoHS certification.

Q: Are there packaging differences between these parts? A: The 1-640431-0 uses standard packaging while the 4-640431-0 is supplied in bulk packaging. Both contain the same connector component; packaging selection depends on production volume and handling requirements.

Q: What is the moisture sensitivity level and why does it matter? A: Both connectors have MSL 1 (Unlimited), indicating they have no moisture sensitivity restrictions and do not require special storage or handling conditions.

Q: Can these connectors be used with both discrete and ribbon cable? A: Yes. Both the 1-640431-0 and 4-640431-0 support discrete or ribbon cable configurations with 18 AWG wire gauge through IDC termination.
