TE Connectivity 643814-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 643814-6 is a 6-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-compliant classification, identification of equivalent active alternatives is necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the 643814-6 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is functional compatibility within the MTA-100 series, which requires matching the following parameters:

• 6-position rectangular receptacle configuration
• 0.100" (2.54mm) pitch spacing
• Single-row layout
• Female socket contact type
• IDC cable termination method
• 24 AWG wire gauge compatibility
• Free hanging (in-line) and right-angle mounting capability
• Locking ramp fastening mechanism
• Closed-end housing design
• 80.0µin (2.03µm) contact finish thickness
• White housing color

The substitute part 3-643814-6 maintains identical electrical and mechanical specifications to the main part while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-643814-6 is the direct equivalent for the obsolete 643814-6. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 643814-6 carries obsolete status, indicating discontinued manufacturing and limited long-term availability. The substitute part 3-643814-6 maintains active product status, ensuring ongoing supply chain support and manufacturing continuity.

Regulatory Compliance: The main part is RoHS non-compliant, while the substitute part 3-643814-6 is RoHS Compliant. This distinction is significant for applications subject to RoHS directives and environmental regulations.

Electrical and Mechanical Equivalence: Both parts maintain identical specifications across all functional parameters, including connector configuration, pitch, contact type, termination method, wire gauge compatibility, and mounting characteristics. The contact finish thickness remains constant at 80.0µin (2.03µm).

Contact Finish Difference: The main part features tin-lead contact finish, while the substitute features tin contact finish. Both finishes maintain the same thickness specification and are compatible with IDC termination and 24 AWG wire applications.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.

For new designs and ongoing procurement, the 3-643814-6 substitute part is the appropriate selection due to active product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the 3-643814-6 substitute directly replace the 643814-6 in existing applications?

A: Yes. The 3-643814-6 maintains identical electrical and mechanical specifications across all functional parameters, including connector configuration, pitch spacing, contact type, IDC termination capability, wire gauge compatibility, and mounting characteristics. Direct substitution is supported without design modification.

Q: What is the difference between the tin-lead finish on the 643814-6 and the tin finish on the 3-643814-6?

A: Both finishes maintain the same thickness specification of 80.0µin (2.03µm). The contact finish difference reflects the RoHS compliance transition from tin-lead to tin. Both finishes are compatible with IDC termination and 24 AWG wire applications.

Q: Why is the 643814-6 classified as obsolete?

A: Obsolete status indicates that the part has been discontinued by the manufacturer. The 3-643814-6 represents the active equivalent within the MTA-100 series and is the recommended selection for ongoing applications.

Q: Are there any packaging differences between the two parts?

A: The main part 643814-6 does not specify packaging information. The substitute part 3-643814-6 is supplied in bulk packaging. Both parts are functionally equivalent for component selection purposes.

Q: Does the RoHS compliance difference affect connector performance?

A: RoHS compliance reflects regulatory and environmental standards rather than electrical or mechanical performance. Both parts maintain identical functional specifications. RoHS compliance is a regulatory requirement for applications subject to RoHS directives.

Q: What is the moisture sensitivity level for both parts?

A: Both the 643814-6 and 3-643814-6 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.

Q: Can the 3-643814-6 be used with discrete or ribbon cable?

A: Yes. The 3-643814-6 supports both discrete and ribbon cable configurations with 24 AWG wire gauge, identical to the main part specification.

Q: Are both parts compatible with the same mating connectors?

A: Yes. Both parts are 6-position rectangular receptacles within the MTA-100 series with 0.100" (2.54mm) pitch spacing. They are compatible with the same mating connector configurations.
