TE Connectivity 644043-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644043-5 is a 5-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG wire. This connector features gold-plated female socket contacts, a closed-end design, and supports both discrete and ribbon cable configurations.

The 644043-5 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and field service requirements for systems utilizing this connector type.

Substitute Part Grouping Explanation

Substitution of the 644043-5 is determined by strict equivalence across the following critical parameters:

Connector Type and Position Count: Both main and substitute parts must be 5-position receptacle connectors
Pitch and Contact Spacing: 0.100" (2.54mm) pitch ensures mechanical and electrical compatibility
Contact Configuration: Female socket contacts with gold finish and 30.0µin (0.76µm) thickness
Termination Method: IDC cable termination for 26 AWG wire compatibility
Series Designation: MTA-100 series classification
Mounting and Fastening: Free hanging in-line and right-angle mounting with locking ramp fastening

The substitute part 3-644043-5 maintains identical electrical and mechanical specifications to the main part, with the primary distinction being product status and packaging configuration.
