TE Connectivity 640441-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640441-4 is a 4-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 of the 640441-4 becomes increasingly difficult. Identifying equivalent substitute parts with matching electrical and mechanical specifications is necessary to maintain design compatibility and ensure continued availability for repair, maintenance, and production applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 640441-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Number of positions (4)
• Contact type (Female Socket)
• Wire gauge (24 AWG)
• Cable termination method (IDC)

Mechanical Compatibility Parameters:

• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Mounting type (Free Hanging, In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Features (Closed End)
• Contact finish thickness (80.0µin / 2.03µm)

Environmental & Regulatory Parameters:

• Moisture Sensitivity Level (1 - Unlimited)
• Series designation (MTA-100)

The substitute part 3-640441-4 maintains full equivalence across all electrical, mechanical, and environmental parameters. The primary distinction is product status and contact finish composition, with the substitute offering active product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 3-640441-4 serves as a direct functional equivalent to the 640441-4 across all critical electrical and mechanical parameters. Selection between these parts is determined by regulatory and product lifecycle requirements:

Select 640441-4 when:

• Legacy system maintenance requires exact original component specifications
• Tin-lead contact finish is explicitly required by design documentation
• Existing inventory of the original part is available

Select 3-640441-4 when:

• RoHS compliance is required for new designs or production
• Active product status and ongoing manufacturer support are necessary
• Tin contact finish meets application requirements
• Long-term component availability is a priority

The 3-640441-4 is the recommended selection for new applications and ongoing production due to active product status and RoHS compliance certification. Both parts maintain identical electrical and mechanical performance within the MTA-100 series specification.

Frequently Asked Questions (FAQ)

Q: Are the 640441-4 and 3-640441-4 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), number of positions (4), mounting type (Free Hanging, In-Line, Right Angle), and fastening mechanism (Locking Ramp). They are mechanically interchangeable in all applications.

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

A: The 640441-4 features tin-lead contact finish, while the 3-640441-4 features tin contact finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin finish in the 3-640441-4 reflects RoHS compliance requirements that restrict lead content in electronic components.

Q: Can the 3-640441-4 be used as a direct replacement for the 640441-4?

A: The 3-640441-4 is functionally equivalent across all electrical and mechanical parameters. Selection depends on regulatory requirements and design specifications. For RoHS-compliant applications, the 3-640441-4 is the appropriate selection.

Q: Why is the 640441-4 listed as obsolete?

A: The 640441-4 is classified as obsolete product status, indicating it is no longer in active production. The 3-640441-4 represents the current active equivalent within the MTA-100 series.

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

A: Yes. Both the 640441-4 and 3-640441-4 are designed for IDC termination with 24 AWG discrete or ribbon cable. They support identical wire gauge and termination methodology.

Q: What is the Moisture Sensitivity Level for these connectors?

A: Both connectors carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Does packaging differ between these parts?

A: The 640441-4 packaging is not specified in available documentation. The 3-640441-4 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
