• Contact Pitch: 0.100" (2.54mm) center-to-center spacing
• Termination Method: IDC (Insulation Displacement Contact) technology
• Wire Gauge Compatibility: 22 AWG discrete or ribbon cable
• Contact Finish: Gold plating at 30.0µin (0.76µm) thickness
• Mechanical Design: Closed-end housing with locking ramp fastening
• Mounting Configuration: Free hanging (in-line) and right-angle orientation support

The substitute part 3-641237-6 maintains identical electrical and mechanical specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The 3-641237-6 is a direct functional equivalent to the 641237-6 with superior procurement advantages. Both parts share identical electrical and mechanical specifications across all critical parameters including connector configuration, contact pitch, termination method, wire gauge compatibility, and contact finish specifications.

The primary distinction between these parts is product lifecycle status. The 641237-6 is classified as obsolete, while the 3-641237-6 maintains active product status with significantly higher inventory availability (1447 pieces versus 637 pieces). Additionally, the 3-641237-6 carries RoHS compliance certification, whereas the 641237-6 status is not applicable.

For new designs, system upgrades, or long-term procurement planning, the 3-641237-6 is the appropriate selection. For legacy system maintenance requiring exact part matching, the 641237-6 remains functionally interchangeable where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can the 3-641237-6 be used as a direct replacement for the 641237-6?

A: Yes. The 3-641237-6 is electrically and mechanically identical to the 641237-6 across all specified parameters. Both connectors feature 6-position IDC receptacle design, 0.100" pitch, 22 AWG wire compatibility, and gold-plated contacts. The parts are fully interchangeable in applications where the 641237-6 was originally specified.

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

A: The primary differences are product status and compliance certification. The 641237-6 is obsolete with limited inventory, while the 3-641237-6 is an active product with higher availability. The 3-641237-6 carries RoHS compliance certification. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between 641237-6 and 3-641237-6?

A: The 641237-6 packaging specification is not provided in the technical data. The 3-641237-6 is supplied in bulk packaging. For specific packaging requirements, consult the detailed product documentation or contact the manufacturer directly.

Q: Does the gold contact finish thickness affect compatibility?

A: No. Both parts specify identical contact finish thickness of 30.0µin (0.76µm). This specification ensures consistent electrical performance and contact resistance across both part numbers.

Q: Are these connectors suitable for ribbon cable applications?

A: Yes. Both the 641237-6 and 3-641237-6 support discrete or ribbon cable termination via IDC technology at 22 AWG wire gauge. The closed-end housing design accommodates standard ribbon cable configurations.

Q: What is the significance of the MTA-100 series designation?

A: The MTA-100 series designation indicates the connector family and establishes compatibility standards for mating components, contact pitch (0.100"), and mechanical interfaces. Both parts belong to this series and maintain full compatibility with other MTA-100 series components.

Q: Is RoHS compliance required for my application?

A: RoHS compliance requirements depend on your application's regulatory jurisdiction and customer specifications. The 3-641237-6 is RoHS compliant, making it suitable for applications with RoHS mandates. The 641237-6 has not applicable RoHS status. Verify your specific compliance requirements before part selection.
