Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 643995-6 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: MTA-156 series designation
• Connector Configuration: 6-position plug with male pin contacts
• Pitch Specification: 0.156" (3.96mm) center-to-center spacing
• Termination Method: IDC (Insulation Displacement Contact) technology
• Wire Gauge Compatibility: 22 AWG
• Contact Finish: Gold plating at 15.0µin (0.38µm) thickness
• Mechanical Design: Closed-end housing with free-hanging, in-line and right-angle mounting capability
• Electrical Performance: Single-row configuration with discrete or ribbon cable support

The substitute part 3-643995-6 maintains identical electrical and mechanical specifications while differing in product status (active versus obsolete) and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The part 3-643995-6 serves as the direct functional equivalent to the obsolete 643995-6. Both components maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, pitch, contact finish, and termination method.

The primary distinction between these parts is regulatory and product lifecycle status. The 3-643995-6 is classified as an active product with RoHS compliance and REACH unaffected status, whereas the 643995-6 is obsolete with non-compliant RoHS classification and undefined REACH status. For applications subject to RoHS or REACH regulatory requirements, the 3-643995-6 is the appropriate selection.

Both parts carry identical moisture sensitivity level (MSL 1) and support unlimited shelf life storage conditions. The 3-643995-6 is available in bulk packaging with 816 pieces in current inventory, compared to 770 pieces of the obsolete variant.

Frequently Asked Questions (FAQ)

Q: Are the 643995-6 and 3-643995-6 electrically and mechanically interchangeable?

A: Yes. Both parts are 6-position MTA-156 series plug connectors with identical pitch (0.156"), contact type (male pin), termination method (IDC), wire gauge (22 AWG), and contact finish specifications (gold at 15.0µin thickness). They support the same cable types and mounting configurations.

Q: What is the primary reason to transition from 643995-6 to 3-643995-6?

A: The 643995-6 is classified as obsolete. The 3-643995-6 is an active product offering continued availability and support. Additionally, the 3-643995-6 is RoHS compliant and REACH unaffected, whereas the 643995-6 is non-compliant and has undefined REACH status.

Q: Do these connectors support both discrete and ribbon cable configurations?

A: Yes. Both the 643995-6 and 3-643995-6 are specified for discrete or ribbon cable wire types with 22 AWG gauge, utilizing IDC termination technology.

Q: What is the difference in packaging between these two parts?

A: The 643995-6 is supplied without specified packaging designation. The 3-643995-6 is supplied in bulk packaging format.

Q: Are there any differences in storage or handling requirements between these parts?

A: No. Both parts carry identical moisture sensitivity level (MSL 1), indicating unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Can the 3-643995-6 be used as a direct replacement in existing designs using 643995-6?

A: Yes. The 3-643995-6 maintains full electrical and mechanical compatibility with the 643995-6 across all specified parameters. No design modifications are required for substitution.
