Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 1-644460-0 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Connector Architecture: Same rectangular receptacle configuration with 10-position capacity and 0.156" (3.96mm) pitch geometry ensures mechanical and electrical compatibility with mating connectors and cable assemblies.

Contact System: Female socket contact type with gold plating at 30.0µin (0.76µm) thickness preserves electrical performance and signal integrity characteristics.

Termination Compatibility: IDC cable termination method with support for 18 AWG discrete or ribbon cable ensures direct compatibility with existing cable assemblies and crimping equipment.

Functional Features: Closed-end design and polarizing key configuration maintain keying and polarization requirements for correct mating orientation.

Compliance and Regulatory Status: RoHS3 compliance, REACH unaffected status, and MSL 1 rating ensure the substitute meets current regulatory requirements and environmental standards.

The substitute part 4-644460-0 satisfies all these criteria while offering the advantage of active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 4-644460-0 is the direct equivalent for the obsolete 1-644460-0. Both parts share identical electrical and mechanical specifications, ensuring full interchangeability in applications requiring 10-position MTA-156 rectangular receptacle connectors with IDC termination for 18 AWG cable.

Product Status Advantage: The substitute part maintains active product status with TE Connectivity, providing assured long-term availability and supply chain continuity. The main part's obsolete classification creates supply risk for new designs and field service requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. MSL 1 rating indicates unlimited shelf life under standard storage conditions.

Supply Availability: The substitute part currently maintains higher inventory levels (1027 pieces) compared to the main part (865 pieces), supporting immediate procurement for production and service applications.

Selection of the 4-644460-0 substitute eliminates obsolescence risk while maintaining complete functional and mechanical compatibility with existing connector systems, mating plugs, and cable assemblies designed for the MTA-156 series.

Frequently Asked Questions (FAQ)

Q: Are the 1-644460-0 and 4-644460-0 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 10-position capacity, 0.156" (3.96mm) pitch, free-hanging in-line mounting, and locking ramp fastening. They mate with identical plug connectors and cable assemblies.
