TE Connectivity 641191-3 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641191-3 is a 3-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 641191-3 carries an obsolete product status. Locating equivalent or substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or repair requirements for legacy systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 641191-3 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 3 positions at 0.100" (2.54mm) spacing
• Termination Method: IDC cable termination for 24 AWG wire
• Contact Material & Finish: Gold plating at 15.0µin thickness
• Mechanical Design: Closed-end receptacle with free-hanging, right-angle mounting and locking ramp fastening
• Series Compatibility: MTA-100 series designation

Substitute parts must maintain identical electrical and mechanical specifications across all parameters listed above. Deviations in any single parameter disqualify a component from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The 3-641191-3 is the direct functional equivalent and recommended substitute for the obsolete 641191-3. Both components share identical electrical and mechanical specifications, ensuring seamless integration into existing designs and assemblies.

The 3-641191-3 offers two significant advantages over the original part:

1. Product Status: The substitute maintains active production status, ensuring reliable long-term availability and supply chain continuity.

2. Regulatory Compliance: The 3-641191-3 achieves ROHS3 compliance, whereas the original 641191-3 is RoHS non-compliant. This compliance improvement supports adherence to current environmental and regulatory standards without requiring design modifications.

Both components maintain identical moisture sensitivity classification (MSL 1), export control designation (EAR99), and tariff classification (HTSUS 8536.69.8000).

Frequently Asked Questions (FAQ)

Q: Can the 3-641191-3 be used as a direct replacement for the 641191-3 in existing assemblies?

A: Yes. The 3-641191-3 is electrically and mechanically identical to the 641191-3 across all specified parameters, including connector type, position count, pitch, termination method, contact finish, and mounting configuration. Direct substitution is supported without design modification.

Q: What is the difference between part numbers 641191-3 and 3-641191-3?

A: Both parts share the same base product number (641191) and are functionally equivalent. The primary differences are product status (obsolete versus active) and RoHS compliance (non-compliant versus ROHS3 compliant). The 3-641191-3 represents the current production variant.

Q: Are there packaging differences between these parts?

A: The original 641191-3 packaging specification is not provided. The 3-641191-3 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the RoHS3 compliance of the 3-641191-3 affect electrical performance?

A: No. RoHS3 compliance is a material composition and environmental standard. The electrical and mechanical performance characteristics remain identical between the two parts.

Q: What wire gauges are compatible with these connectors?

A: Both the 641191-3 and 3-641191-3 are rated for 24 AWG wire and support discrete or ribbon cable configurations via IDC termination.

Q: Are these connectors suitable for high-reliability applications?

A: Both connectors feature gold-plated contacts (15.0µin thickness) and closed-end design, supporting applications requiring reliable electrical contact. Moisture sensitivity level 1 (unlimited) indicates no moisture-related restrictions.

Q: Can these 3-position connectors be used in applications requiring different position counts?

A: No. These connectors are specifically designed for 3-position configurations. Different position requirements necessitate alternative part numbers within the MTA-100 series.
