TE Connectivity 644020-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644020-7 is a 7-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 24 AWG wire. This connector features gold-plated female socket contacts, a closed-end design, and supports both discrete and ribbon cable configurations. The part is classified as obsolete, making identification of active equivalent components essential for procurement and design continuity. The substitute part 3-644020-7 provides functional equivalence with active product status and identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 3-644020-7 qualifies as a direct equivalent based on the following critical parameters:

• Connector Configuration: Both parts are 7-position rectangular receptacles with identical 0.100" (2.54mm) pitch
• Contact Specifications: Both feature female socket contacts with gold plating at 30.0µin (0.76µm) thickness
• Termination Method: Both utilize IDC termination for 24 AWG wire
• Mechanical Design: Both support free hanging in-line and right-angle mounting with locking ramp fastening
• Series Designation: Both belong to the MTA-100 series
• Regulatory Compliance: Both are RoHS compliant with MSL 1 (Unlimited) rating

The primary distinction is product status: 644020-7 is obsolete while 3-644020-7 maintains active status. Packaging differs (unspecified versus bulk), but this does not affect functional compatibility.

Engineering Selection Recommendations

The part 3-644020-7 is the direct substitute for the obsolete 644020-7. Selection of the substitute is based on the following engineering criteria:

Product Status Alignment: The substitute maintains active product status with TE Connectivity, ensuring continued availability and manufacturing support. The obsolete status of 644020-7 necessitates transition to an active equivalent for new designs and ongoing procurement.

Regulatory Compliance: Both parts maintain identical RoHS compliance and MSL 1 ratings, confirming suitability for equivalent applications without additional environmental or regulatory qualification.

Electrical and Mechanical Equivalence: All critical parameters—connector geometry, contact configuration, termination method, and fastening mechanism—are identical between the main part and substitute, ensuring direct functional interchangeability in existing circuit designs and assemblies.

Packaging Consideration: The substitute is supplied in bulk packaging, which may require adjustment to procurement and inventory management procedures but does not affect component performance or compatibility.
