TE Connectivity 641239-7 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641239-7 is a 7-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 is rated for discrete or ribbon cable applications.

The 641239-7 carries an obsolete product status. Identification of functionally equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements where this connector is specified in existing designs or legacy systems.

Substitute Part Grouping Explanation

Substitution of the 641239-7 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 7 positions at 0.100" (2.54mm) spacing
Termination Method: IDC cable termination for 26 AWG wire
Contact Material & Finish: Gold plating at 30.0µin (0.76µm) thickness
Mechanical Design: Closed-end housing with free hanging, right-angle mounting and locking ramp fastening
Series Designation: MTA-100 series compatibility
Regulatory Compliance: RoHS compliance and MSL rating

The substitute part 3-641239-7 maintains identical electrical and mechanical specifications across all these parameters, differing only in product status (active versus obsolete) and packaging configuration (bulk versus standard).
