TE Connectivity 641191-2 MTA-100 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641191-2 is a 2-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 gold-plated female socket contacts, a closed-end design, and white housing with a locking ramp fastening mechanism.

The 641191-2 is classified as obsolete. Identification of active equivalent parts is necessary to ensure continued availability, supply chain reliability, and compliance with current regulatory standards for new designs and production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 641191-2 is based on electrical and mechanical parameter equivalence within the MTA-100 connector series. The substitute part must satisfy the following criteria:

Critical Substitution Parameters:

• Connector type: Rectangular receptacle
• Number of positions: 2
• Pitch: 0.100" (2.54mm)
• Contact type: Female socket
• Cable termination: IDC
• Wire gauge: 24 AWG
• Contact finish: Gold with 15.0µin thickness
• Mounting configuration: Free hanging (in-line), right angle
• Fastening mechanism: Locking ramp
• Housing color: White
• Series designation: MTA-100

The substitute part 3-641191-2 meets all electrical and mechanical parameters required for direct substitution. The primary distinction is product status: the substitute is active and currently manufactured, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-641191-2 is the direct equivalent for the obsolete 641191-2. All electrical and mechanical parameters are identical, ensuring functional and physical compatibility in existing applications.

Product Status Advantage: The substitute part carries an active product status, indicating current manufacturing and ongoing availability from TE Connectivity. This eliminates supply chain risk associated with obsolete components.

Regulatory Compliance: The substitute part meets ROHS3 compliance, representing an updated regulatory certification relative to the original RoHS Compliant designation. The REACH Unaffected status provides explicit regulatory clarity. Both parts maintain identical ECCN and HTSUS classifications.

Packaging Consideration: The substitute part is supplied in bulk packaging, whereas the original part packaging specification was not provided. Bulk packaging is standard for active production components and does not affect electrical or mechanical performance.

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

For new designs, production runs, and component replacement in existing systems, the 3-641191-2 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 3-641191-2 substitute directly for the 641191-2 in existing applications?
