TE Connectivity 640440-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 640440-6 is a 6-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and right-angle mounting configuration with locking ramp fastening.

The 640440-6 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements for legacy systems utilizing this connector type. Active production alternatives within the same series provide functional compatibility while offering improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 640440-6 is determined by strict alignment with the following electrical and mechanical parameters:

• Connector Type & Configuration: Must be rectangular receptacle with female socket contacts
• Position Count & Pitch: Must maintain 6 positions at 0.100" (2.54mm) pitch in single-row configuration
• Termination Method: Must support IDC termination for 22 AWG wire
• Mounting & Fastening: Must provide free hanging in-line and right-angle mounting with locking ramp fastening
• Contact Finish Specifications: Must maintain 80.0µin (2.03µm) contact finish thickness
• Physical Features: Must include closed-end design and red color
• Series Designation: Must belong to the MTA-100 series

The substitute part 3-640440-6 satisfies all substitution criteria. The primary distinction is the contact finish material (tin versus tin-lead) and product status transition from obsolete to active, along with improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 3-640440-6

The 3-640440-6 is the direct functional equivalent of the 640440-6 and is the recommended substitute for all applications. This part maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, termination method, wire gauge, mounting configuration, and fastening mechanism.

Compliance Advantages:

The 3-640440-6 offers improved regulatory compliance status. It is ROHS3 compliant, whereas the original 640440-6 is RoHS non-compliant. This distinction is significant for applications subject to RoHS directives and environmental regulations.

Product Status:

The 3-640440-6 carries active product status with 2400 units in stock, compared to the obsolete status of the 640440-6. Active status ensures continued availability and support from the manufacturer.

Contact Finish Consideration:

The substitute part features tin contact finish in place of the original tin-lead finish. Both finishes maintain the specified 80.0µin (2.03µm) thickness. The tin finish in the substitute part aligns with the RoHS3 compliance requirement and represents standard industry practice for lead-free applications.

Packaging:

The 3-640440-6 is supplied in bulk packaging, whereas the original part packaging is unspecified. This distinction does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 3-640440-6 be used as a direct replacement for the 640440-6 in existing assemblies?

A: Yes. The 3-640440-6 maintains identical electrical and mechanical specifications across all critical parameters. The connector type, position count, pitch, termination method, wire gauge, mounting configuration, and fastening mechanism are identical. The substitute part is functionally interchangeable.

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

A: Both finishes maintain the specified 80.0µin (2.03µm) thickness and provide equivalent electrical performance in IDC termination applications. The tin finish in the substitute part is lead-free and complies with RoHS3 regulations, whereas the original tin-lead finish does not.

Q: Why is the 640440-6 classified as obsolete?

A: The 640440-6 is no longer in active production. The 3-640440-6 represents the current active production equivalent within the MTA-100 series.

Q: Are there any compatibility issues when substituting the 3-640440-6 for the 640440-6?

A: No compatibility issues exist. Both connectors are designed for identical IDC termination with 22 AWG discrete or ribbon cable, feature the same 0.100" (2.54mm) pitch, and provide identical mounting and fastening configurations.

Q: What is the inventory status of these parts?

A: The 640440-6 has 681 units in stock. The 3-640440-6 has 2400 units in stock, providing greater availability for ongoing requirements.

Q: Does the packaging difference affect the connector specifications?

A: No. Packaging format does not affect electrical or mechanical specifications. The bulk packaging of the 3-640440-6 is a supply format distinction only.

Q: Are both parts subject to the same export classifications?

A: Yes. Both parts carry the same ECCN (EAR99) and HTSUS (8536.69.8000) classifications.
