TE Connectivity 640441-7 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640441-7 is a 7-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 24 AWG discrete or ribbon cable. This connector features tin-lead contact finish and is classified as obsolete product status.

Due to its obsolete classification, locating original inventory becomes increasingly difficult. A direct substitute with improved product status and compliance characteristics is available to ensure continued design support and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 3-640441-7 is classified as a direct equivalent based on the following critical parameters that determine functional interchangeability:

Electrical Parameters:

• Identical number of positions (7)
• Identical pitch spacing (0.100" / 2.54mm)
• Identical wire gauge specification (24 AWG)
• Identical contact type (Female Socket)
• Identical contact finish thickness (80.0µin / 2.03µm)

Mechanical Parameters:

• Identical mounting type (Free Hanging In-Line, Right Angle)
• Identical fastening type (Locking Ramp)
• Identical cable termination method (IDC)
• Identical number of rows (1)
• Identical connector features (Closed End)

Environmental Parameters:

• Identical Moisture Sensitivity Level (MSL 1 - Unlimited)
• Identical series designation (MTA-100)

The primary difference between the main part and substitute is the contact finish material (tin-lead versus tin) and product status (obsolete versus active). Both finishes meet the specified thickness requirement and maintain electrical performance within the MTA-100 series specifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Redesigns: Part number 3-640441-7 is the appropriate selection. This part maintains active product status with TE Connectivity, ensuring long-term availability and design support. The part is RoHS compliant, meeting current environmental and regulatory requirements for commercial and industrial applications.

For Existing Inventory Management: The 640441-7 remains functionally equivalent for applications where tin-lead contact finish is acceptable and RoHS compliance is not a requirement. However, transition to 3-640441-7 is recommended to align with modern supply chain practices and regulatory standards.

Contact Finish Consideration: Both tin-lead and tin finishes provide equivalent electrical performance at the specified thickness of 80.0µin (2.03µm). The selection between these finishes depends on application-specific requirements and soldering process compatibility, not on connector functionality within the MTA-100 series.

Frequently Asked Questions (FAQ)

Q: Are the 640441-7 and 3-640441-7 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.100"), mounting type (Free Hanging In-Line, Right Angle), fastening type (Locking Ramp), and number of positions (7). They are designed to mate with identical complementary connectors and accept the same cable types and gauges.

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

A: Both finishes are applied at the same thickness (80.0µin / 2.03µm) and provide equivalent electrical conductivity and contact resistance. The primary difference is material composition. Tin-lead finishes are associated with older manufacturing standards, while tin finishes align with RoHS compliance requirements. Selection depends on application soldering process and regulatory requirements.

Q: Can I use 3-640441-7 as a direct replacement in existing assemblies designed for 640441-7?

A: Yes. The 3-640441-7 is electrically and mechanically equivalent. It will function identically in applications currently using the 640441-7. The active product status of 3-640441-7 provides superior supply chain reliability.

Q: Why is the 640441-7 classified as obsolete?

A: Obsolete classification indicates that TE Connectivity has discontinued active production and support for this part number. The 3-640441-7 represents the current active equivalent within the MTA-100 series.

Q: What does RoHS compliance mean for connector selection?

A: RoHS (Restriction of Hazardous Substances) compliance restricts the use of lead and other hazardous materials. The 3-640441-7 is RoHS compliant, making it suitable for applications subject to environmental regulations and industry standards that mandate RoHS compliance. The 640441-7 is non-compliant and may not be acceptable for regulated applications.

Q: Are both parts suitable for IDC termination with 24 AWG ribbon cable?

A: Yes. Both the 640441-7 and 3-640441-7 are designed for IDC termination and accept 24 AWG discrete or ribbon cable. The IDC termination method and wire gauge specifications are identical between both parts.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these connectors have unlimited shelf life and do not require special moisture-controlled storage conditions. Both parts carry this rating.
