The primary distinction between these parts is packaging configuration: the 644042-6 is supplied in standard packaging, while the 3-644042-6 is supplied in bulk packaging. This packaging difference does not affect connector performance, mating characteristics, or electrical properties.

For applications currently utilizing the 644042-6, the 3-644042-6 provides direct substitution without design modification or performance compromise.

Frequently Asked Questions (FAQ)

Q: Can the 3-644042-6 directly replace the 644042-6 in existing designs?

A: Yes. The 3-644042-6 is electrically and mechanically identical to the 644042-6. Both connectors feature 6 positions at 0.100" pitch, gold-plated female socket contacts, IDC termination for 22 AWG wire, and identical mounting configurations. No design changes are required.

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

A: The 644042-6 is classified as obsolete, indicating TE Connectivity no longer manufactures this specific part number. The 3-644042-6 maintains active status, confirming current production and availability. For new designs and ongoing supply requirements, the 3-644042-6 is the recommended selection.

Q: How do the packaging differences affect connector selection?

A: The 644042-6 uses standard packaging while the 3-644042-6 uses bulk packaging. This distinction affects order quantities and logistics but does not impact connector electrical performance, mechanical fit, or mating characteristics. Packaging selection depends on procurement volume and inventory management requirements.

Q: Are both connectors compliant with current regulatory standards?

A: Yes. Both the 644042-6 and 3-644042-6 are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) ratings. Both parts meet current environmental and regulatory requirements for electronic component applications.

Q: What wire gauges and termination methods are supported?

A: Both connectors support 22 AWG wire with IDC (Insulation Displacement Contact) termination. They accommodate discrete or ribbon cable configurations. The IDC termination method eliminates the need for individual wire stripping and crimping, enabling efficient assembly of multi-conductor cable assemblies.

Q: Can these connectors be used in both in-line and right-angle mounting configurations?

A: Yes. Both the 644042-6 and 3-644042-6 support free hanging mounting in both in-line and right-angle orientations. The locking ramp fastening mechanism secures the connector to mating plugs in either configuration.
