TE Connectivity 644043-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 644043-6 is a 6-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG wire. This connector features gold-plated female socket contacts, a closed-end design, and supports both discrete and ribbon cable configurations. The part is currently active in production with 744 pieces available in original inventory.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across connector type, contact configuration, pitch, wire gauge, and termination method. Alternative part numbers may offer different packaging formats or enhanced compliance certifications while preserving functional interchangeability.

• Bulk packaging format aligns with high-volume manufacturing or distribution requirements
• Higher inventory availability (2324 pieces) supports extended production schedules
• ROHS3 compliance certification is mandated by design specifications or customer requirements
• REACH compliance documentation is required for supply chain compliance

Both parts maintain identical electrical performance, mechanical compatibility, and moisture sensitivity ratings. The substitute part offers enhanced regulatory compliance certifications while preserving all functional specifications of the original part number.

Frequently Asked Questions (FAQ)

Q: Are 644043-6 and 3-644043-6 electrically interchangeable?

A: Yes. Both parts are identical in electrical specifications, including contact type, pitch, wire gauge, contact finish, and finish thickness. They function identically in circuits and applications.

Q: What is the primary difference between these two part numbers?

A: The primary difference is packaging format. The 644043-6 uses standard packaging, while 3-644043-6 is supplied in bulk packaging. Additionally, 3-644043-6 carries ROHS3 compliance certification and REACH compliance documentation, whereas 644043-6 lists these as not applicable or vendor undefined.

Q: Can I use 3-644043-6 as a direct replacement for 644043-6 in existing designs?

A: Yes. The substitute part maintains all mechanical and electrical specifications required for direct substitution. No circuit redesign or connector interface modifications are necessary.

Q: Does packaging format affect connector performance?

A: No. Packaging format is a logistics and supply chain consideration only. It does not affect the electrical or mechanical performance of the connector itself.

Q: Which part should I specify for new designs?

A: Selection depends on your compliance requirements and supply chain preferences. If ROHS3 and REACH compliance documentation are required, specify 3-644043-6. If standard packaging and existing compliance status are acceptable, either part number is suitable.

Q: Are there any wire gauge or pitch restrictions when using these connectors?

A: No. Both parts are rated for 26 AWG wire exclusively and operate at 0.100" (2.54mm) pitch. These specifications are fixed and not adjustable.

Q: Can these connectors accommodate both discrete and ribbon cable?

A: Yes. Both 644043-6 and 3-644043-6 support discrete wire and ribbon cable configurations through IDC termination.

Q: What is the contact finish thickness tolerance?

A: The gold contact finish is specified at 30.0µin (0.76µm) for both part numbers. This thickness is consistent across all units.
