TE Connectivity 640442-4 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640442-4 is a 4-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 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. Direct substitutes with active product status and improved compliance certifications are available to ensure continued system support and procurement reliability.

• Pitch (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge (26 AWG)
• Wire type (Discrete or Ribbon Cable)

Mechanical Compatibility Parameters:

• Mounting type (Free Hanging In-Line, Right Angle)
• Fastening type (Locking Ramp)
• Features (Closed End)
• Number of rows (1)
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Blue)
• Series designation (MTA-100)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (1 - Unlimited)
• ECCN classification (EAR99)
• HTSUS code (8536.69.8000)

The substitute part 3-640442-4 maintains full equivalence across all electrical, mechanical, and environmental parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 3-640442-4

The 3-640442-4 is the direct equivalent substitute for the obsolete 640442-4. This part maintains full electrical and mechanical compatibility across all critical parameters including connector type, position count, pitch, contact configuration, IDC termination method, wire gauge, mounting type, and fastening mechanism.

Compliance Advantages:

The substitute part 3-640442-4 offers improved compliance status:

• Active product status ensures ongoing availability and manufacturing support
• RoHS Compliant certification (versus RoHS non-compliant for the main part)
• Maintains EAR99 ECCN classification and 8536.69.8000 HTSUS code equivalence

Contact Finish Consideration:

The substitute part features tin contact finish compared to tin-lead on the original part. Both finishes maintain the specified 80.0µin (2.03µm) thickness. This change aligns with RoHS compliance requirements and does not affect electrical performance or mechanical compatibility within the MTA-100 series connector system.

Packaging:

The substitute part is supplied in bulk packaging, compared to the original part's unspecified packaging. Inventory availability for the 3-640442-4 is significantly higher (13,018 pieces versus 1,110 pieces), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the 3-640442-4 directly replace the 640442-4 in existing applications?

A: Yes. The 3-640442-4 maintains full electrical and mechanical equivalence across all critical parameters: 4-position receptacle configuration, 0.100" pitch, female socket contacts, IDC termination for 26 AWG cable, free hanging in-line and right angle mounting, locking ramp fastening, and closed end design. Both parts are MTA-100 series connectors with identical contact finish thickness and moisture sensitivity ratings.

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

A: Both finishes are applied at 80.0µin (2.03µm) thickness and provide equivalent electrical conductivity and contact performance. The tin finish on the 3-640442-4 reflects RoHS compliance requirements. The contact finish does not affect mechanical mating, IDC termination, or electrical characteristics within this connector application.

Q: Why is the 640442-4 classified as obsolete?

A: Obsolete classification indicates the part is no longer in active production. The 3-640442-4 serves as the active production equivalent, offering the same functionality with improved compliance certifications and sustained manufacturing support.

Q: Are there any compatibility issues with ribbon cable or discrete wire?

A: No. Both the main part and substitute support identical wire types: discrete or ribbon cable at 26 AWG. The IDC termination method and connector geometry are unchanged between parts.

Q: What is the significance of the MTA-100 series designation?

A: MTA-100 is the connector series specification that defines the 0.100" (2.54mm) pitch standard and mechanical interface. Both the 640442-4 and 3-640442-4 conform to this series standard, ensuring full compatibility with mating connectors and cable assemblies designed for MTA-100 receptacles.

Q: Does the bulk packaging of the 3-640442-4 affect component quality?

A: No. Packaging type does not affect electrical or mechanical specifications. Bulk packaging is a standard distribution method for high-volume procurement and does not alter connector performance, contact finish, or reliability characteristics.

Q: Are there any environmental or regulatory differences between these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. The primary regulatory difference is RoHS compliance status: the 3-640442-4 is RoHS Compliant, while the 640442-4 is RoHS non-compliant. Both maintain Moisture Sensitivity Level 1 (Unlimited) rating.
