TE Connectivity 640441-8 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640441-8 is an 8-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. Due to its obsolete product status and RoHS non-compliance, identification of equivalent substitute parts is necessary for ongoing design support, maintenance, and new procurement activities.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 640441-8 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (8)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Cable termination method (IDC)
• Wire gauge compatibility (24 AWG)

Mechanical Parameters:

• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Features (Closed End)
• Color (White)

Material & Environmental Parameters:

• Contact finish thickness (80.0µin / 2.03µm)
• Moisture sensitivity level (1 - Unlimited)

The substitute part 3-640441-8 maintains identical electrical and mechanical specifications while differing in contact finish composition (tin versus tin-lead) and product compliance status. This substitution is valid for applications where the connector footprint, termination method, and electrical performance requirements remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The 640441-8 is classified as obsolete. The direct substitute part 3-640441-8 is an active product from the same manufacturer and series, maintaining identical electrical and mechanical specifications. This substitute is suitable for direct replacement in existing designs and for new procurement activities.

For RoHS Compliance Requirements:

Applications subject to RoHS compliance mandates must transition to part 3-640441-8, which carries RoHS Compliant certification. The 640441-8 is RoHS non-compliant and unsuitable for regulated markets and applications requiring environmental compliance documentation.

Contact Finish Consideration:

The primary difference between the main part and substitute is the contact finish material. The 640441-8 features tin-lead finish, while 3-640441-8 features tin finish. Both maintain identical contact finish thickness (80.0µin / 2.03µm) and are functionally equivalent for IDC termination applications with 24 AWG cable.

Inventory and Availability:

The substitute part 3-640441-8 is currently in active production with higher inventory availability (2200 pcs) compared to the obsolete main part (801 pcs). For long-term supply chain stability, 3-640441-8 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can 3-640441-8 directly replace 640441-8 in existing assemblies?

A: Yes. The 3-640441-8 is a direct functional equivalent with identical connector type, position count, pitch, mounting configuration, and IDC termination method. Physical and electrical compatibility is maintained.

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

A: Both finishes are applied at identical thickness (80.0µin / 2.03µm) and provide equivalent electrical performance for IDC applications. Tin finish (3-640441-8) is RoHS compliant, while tin-lead finish (640441-8) is not. Contact finish selection is driven by regulatory compliance requirements rather than electrical performance.

Q: Is the 3-640441-8 suitable for new product designs?

A: Yes. The 3-640441-8 is an active product with RoHS compliance certification, making it appropriate for new designs, particularly those subject to environmental regulations or customer compliance requirements.

Q: Are there any mechanical differences between these parts?

A: No. Both parts share identical mechanical specifications: 8-position, 0.100" pitch, single-row configuration, free-hanging in-line and right-angle mounting options, locking ramp fastening, and closed-end design.

Q: What cable types are compatible with both connectors?

A: Both the 640441-8 and 3-640441-8 accept discrete or ribbon cable at 24 AWG wire gauge via IDC termination method.

Q: Does moisture sensitivity differ between these parts?

A: No. Both parts carry identical Moisture Sensitivity Level 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage or handling.

Q: What is the packaging difference?

A: The 640441-8 packaging specification is not provided. The 3-640441-8 is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.
