TE Connectivity 644083-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644083-6 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 and is classified as obsolete product status. Due to its obsolete classification, identification of active equivalent parts is necessary to ensure continued availability and supply chain continuity for applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 3-644083-6 qualifies as a direct equivalent based on the following critical parameters that determine substitution compatibility:

Matching Parameters:

• Series designation (MTA-100)
• Connector type and contact configuration (6-position receptacle, female socket)
• Pitch specification (0.100" / 2.54mm)
• Cable termination method (IDC)
• Wire gauge compatibility (22 AWG)
• Mounting orientation (Free Hanging In-Line, Right Angle)
• Fastening mechanism (Locking Ramp)
• Closed-end feature
• Contact finish thickness (80.0µin / 2.03µm)
• Color (Black)
• Base product number (644083)

Distinguishing Characteristics: The substitute part differs in contact finish composition (tin versus tin-lead), product status (active versus obsolete), RoHS compliance status, and packaging configuration. These differences do not affect the mechanical or electrical interface compatibility for standard IDC cable termination applications.

Engineering Selection Recommendations

Primary Recommendation: 3-644083-6

The part 3-644083-6 is the direct substitute for the obsolete 644083-6. Selection of this substitute is based on the following engineering criteria:

1. Product Status: The substitute maintains active product status, ensuring ongoing availability and supply chain support. The original part is classified as obsolete, creating supply risk for new applications or replacement requirements.

2. Compliance Status: The substitute achieves RoHS compliance, aligning with current regulatory requirements for electronic components in most markets. The original part is RoHS non-compliant, which may restrict its use in regulated applications or regions with RoHS mandates.

3. Interface Compatibility: All mechanical and electrical interface parameters are identical between the main part and substitute, including connector geometry, pitch, contact configuration, termination method, and wire gauge specifications.

4. Contact Finish Composition: The substitute uses tin finish instead of tin-lead. Both finishes maintain the specified contact finish thickness of 80.0µin (2.03µm) and are compatible with IDC termination processes for 22 AWG cable.

5. Moisture Sensitivity: Both parts share identical MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.

Frequently Asked Questions (FAQ)

Q: Can 3-644083-6 be used as a direct replacement for 644083-6 in existing applications?

A: Yes. The substitute part 3-644083-6 maintains identical mechanical and electrical interface specifications, including connector type, position count, pitch, mounting configuration, and IDC termination compatibility. Both parts are designed for 22 AWG discrete or ribbon cable and feature the same closed-end design with locking ramp fastening.

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

A: The main part features tin-lead contact finish, while the substitute features tin finish. Both maintain the same contact finish thickness of 80.0µin (2.03µm). The tin finish in the substitute part eliminates lead content, enabling RoHS compliance while maintaining electrical and mechanical performance for IDC applications.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation and market demand. The substitute part 3-644083-6 remains in active production status, providing continued availability for applications requiring MTA-100 series 6-position receptacle connectors with IDC termination.

Q: Are there packaging differences between these parts?

A: The original part 644083-6 packaging specification is not defined in the provided data. The substitute part 3-644083-6 is supplied in bulk packaging. Packaging configuration does not affect connector functionality or interface compatibility.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status reflects regulatory material composition requirements and does not alter the electrical performance or signal integrity characteristics of the connector. Both parts meet identical electrical specifications for IDC termination with 22 AWG cable.

Q: What is the moisture sensitivity level for these connectors?

A: Both the original part and substitute are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints. These connectors do not require special moisture control during storage, handling, or assembly processes.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the original part and substitute support IDC termination with discrete or ribbon cable configurations at 22 AWG wire gauge. The closed-end design and locking ramp fastening accommodate both cable types.
