Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict equivalence across the following critical parameters:

• Connector Type and Contact Configuration: Both the main part and substitute must be receptacles with female socket contacts to ensure mating compatibility with corresponding plug connectors.
• Position Count and Pitch: The 14-position configuration at 0.100" (2.54mm) pitch must be maintained to preserve PCB layout and connector footprint compatibility.
• Termination Method: IDC termination capability is required for compatibility with existing cable assemblies and termination equipment.
• Wire Gauge Specification: 28 AWG wire gauge must be maintained to ensure proper contact engagement and electrical performance.
• Contact Material and Finish: Gold plating at 30.0µin thickness is specified for corrosion resistance and electrical conductivity.
• Mechanical Features: Closed-end design and locking ramp fastening type must be preserved for mechanical integrity and assembly compatibility.

The substitute part 4-641240-4 meets all these critical parameters while offering the advantage of active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The 4-641240-4 is the direct substitute for the obsolete 1-641240-4. Both connectors share identical electrical and mechanical specifications within the MTA-100 series, ensuring full functional compatibility.

Product Status Consideration: The 1-641240-4 is classified as obsolete, which restricts long-term availability and supply chain reliability. The 4-641240-4 maintains active product status, ensuring continued manufacturing support and availability for future procurement requirements.

Compliance Status: The 4-641240-4 is RoHS3 compliant, whereas the 1-641240-4 is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the 4-641240-4 is the appropriate selection. Both parts carry identical ECCN and HTSUS classifications.

Mounting Configuration: The 4-641240-4 supports both free-hanging in-line and right-angle mounting options, providing greater design flexibility compared to the 1-641240-4, which is limited to free-hanging in-line mounting.

Inventory and Lead Time: The 4-641240-4 is available in higher inventory quantities (1572 pieces) compared to the 1-641240-4 (620 pieces), supporting faster procurement cycles and reduced lead times.

Frequently Asked Questions (FAQ)

Q: Can the 4-641240-4 be used as a direct replacement for the 1-641240-4 in existing assemblies?

A: Yes. The 4-641240-4 is electrically and mechanically equivalent to the 1-641240-4. Both connectors feature identical 14-position configuration, 0.100" pitch, IDC termination, 28 AWG wire gauge, and gold contact finish. The connectors are fully interchangeable in applications where the 1-641240-4 was originally specified.

Q: What is the significance of the product status difference between these parts?

A: The 1-641240-4 is classified as obsolete, indicating that TE Connectivity has discontinued active manufacturing and support for this part number. The 4-641240-4 maintains active product status, ensuring ongoing availability, manufacturing support, and compliance with current industry standards. For new designs and long-term production requirements, the 4-641240-4 is the recommended selection.

Q: Are there any differences in contact engagement or mating force between these connectors?

A: No. Both connectors utilize identical contact materials, finish specifications (30.0µin gold plating), and mechanical design within the MTA-100 series. Contact engagement characteristics and mating force are equivalent.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both connectors meet identical electrical specifications. However, for applications subject to RoHS directives or customer compliance mandates, the 4-641240-4 is the appropriate selection.

Q: Can the 4-641240-4 be used in right-angle mounting applications?

A: Yes. The 4-641240-4 supports both free-hanging in-line and right-angle mounting configurations. The 1-641240-4 is limited to free-hanging in-line mounting. This additional mounting flexibility in the 4-641240-4 provides design advantages for space-constrained applications.

Q: Are the packaging specifications different between these parts?

A: The 1-641240-4 packaging specification is not defined in the available data. The 4-641240-4 is supplied in bulk packaging. Confirm specific packaging requirements with your procurement or supply chain department when ordering.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors are rated at Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. These connectors do not require special storage or handling conditions related to moisture exposure.
