Key Parameters

Substitute Part Grouping Explanation

Substitution of the 641191-6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series designation (MTA-100)
• Number of positions (6)
• Pitch specification (0.100" / 2.54mm)
• Connector type (Receptacle)
• Contact type (Female Socket)
• Cable termination method (IDC)
• Wire gauge compatibility (24 AWG)
• Contact finish (Gold)
• Fastening mechanism (Locking Ramp)

The substitute part 3-641191-6 maintains full equivalence across all mandatory parameters. The primary distinction is product status: the substitute is active and available, whereas the original part is obsolete. Both parts share the same base product number (641191) and are manufactured by TE Connectivity AMP Connectors within the MTA-100 rectangular connector series.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 3-641191-6

The part 3-641191-6 is the direct substitute for the obsolete 641191-6. Selection of this substitute is based on the following engineering criteria:

Product Status and Availability: The 3-641191-6 maintains active product status with confirmed inventory availability (2658 pieces in stock), whereas the original 641191-6 is obsolete. This substitution ensures continued access to functionally equivalent components for new production, field replacements, and system maintenance.

Electrical and Mechanical Equivalence: All critical electrical parameters are identical: 6-position configuration, 0.100" pitch, female socket contacts, gold finish at 15.0µin thickness, and 24 AWG wire gauge compatibility. Mechanical parameters including IDC termination, locking ramp fastening, and closed-end design are fully preserved.

Compliance and Regulatory Status: Both parts maintain equivalent regulatory compliance. The substitute carries RoHS Compliant certification and REACH Unaffected status, compared to the original ROHS3 Compliant designation. Both share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. MSL rating remains 1 (Unlimited) for both parts.

Packaging Consideration: The substitute is supplied in bulk packaging, whereas the original packaging specification is not defined. This represents a logistical difference without impact on functional compatibility.

Mounting Configuration: The substitute supports both free-hanging in-line and right-angle mounting options, providing additional application flexibility compared to the original free-hanging in-line configuration. This expanded capability does not restrict compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 3-641191-6 be used as a direct replacement for the 641191-6 in existing designs?

A: Yes. The 3-641191-6 is electrically and mechanically equivalent to the 641191-6 across all critical parameters: connector type, position count, pitch, contact configuration, termination method, and wire gauge. Both parts are MTA-100 series receptacles with identical gold-plated contact specifications and locking ramp fastening.

Q: What is the primary reason for substitution?

A: The 641191-6 is classified as obsolete. The 3-641191-6 is an active product with confirmed inventory availability, ensuring supply chain continuity for production and field service applications.

Q: Are there differences in mounting capability between these parts?

A: The substitute 3-641191-6 supports both free-hanging in-line and right-angle mounting configurations, whereas the original 641191-6 is specified for free-hanging in-line mounting only. This expanded capability in the substitute does not restrict its use in applications designed for the original part.

Q: Do the parts have different compliance certifications?

A: Both parts maintain equivalent regulatory compliance. The original carries ROHS3 Compliant certification; the substitute carries RoHS Compliant certification. Both are classified as REACH Unaffected or Vendor Undefined, with identical ECCN and HTSUS codes. MSL ratings are identical at level 1 (Unlimited).

Q: What wire types are compatible with each part?

A: The original 641191-6 is specified for discrete wire termination at 24 AWG. The substitute 3-641191-6 supports both discrete wire and ribbon cable termination at 24 AWG, providing expanded application flexibility while maintaining full compatibility with the original discrete wire specification.

Q: Is there a difference in contact finish specifications?

A: No. Both parts feature gold-plated contacts with identical finish thickness of 15.0µin (0.38µm).

Q: What is the inventory status of each part?

A: The original 641191-6 has 1114 pieces in stock but is obsolete. The substitute 3-641191-6 has 2658 pieces in stock and is an active product, providing superior long-term availability.

Q: Are the pitch and position specifications identical?

A: Yes. Both parts are 6-position connectors with 0.100" (2.54mm) pitch, maintaining full mechanical and electrical compatibility.
