Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-746290-1 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 60 positions, 2 rows, 0.100" pitch and row spacing
• Termination Method: IDC cable termination for ribbon cable
• Wire Compatibility: 26-28 AWG wire gauge
• Contact Properties: Gold finish at 30.0µin (0.76µm) thickness
• Functional Features: Feed-through capability and free-hanging in-line mounting

The 3M 89160-0001 satisfies all these parameters, establishing it as a direct functional equivalent. Differences in contact type designation (Forked versus Female Socket) and housing color do not affect electrical or mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The 3M 89160-0001 serves as the primary substitute for the obsolete TE Connectivity 1-746290-1. Selection of the 3M component is supported by the following factors:

Product Status: The 3M 89160-0001 maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete TE Connectivity part.

Regulatory Compliance: The 3M 89160-0001 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The TE Connectivity 1-746290-1 is RoHS non-compliant with undefined REACH status, presenting compliance limitations for new applications.

Electrical and Mechanical Equivalence: Both connectors maintain identical specifications across all critical parameters including position count, pitch, row configuration, IDC termination method, wire gauge compatibility, and contact finish properties.

Moisture Sensitivity: Both components share MSL Rating 1 (Unlimited), indicating equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M 89160-0001 directly replace the TE Connectivity 1-746290-1 in existing applications?

A: Yes. The 3M 89160-0001 maintains electrical and mechanical equivalence across all specified parameters including connector configuration, IDC termination compatibility, wire gauge support, and contact finish specifications. Physical housing color difference (gray versus black) does not affect functional compatibility.

Q: What is the significance of the obsolete status of the TE Connectivity 1-746290-1?

A: Obsolete status indicates the part is no longer manufactured or supported by TE Connectivity. The 3M 89160-0001 is an active product with ongoing manufacturing and supply availability, making it the appropriate choice for replacement and new designs.

Q: Are there compliance differences between these two connectors?

A: Yes. The 3M 89160-0001 is ROHS3 compliant and REACH unaffected, while the TE Connectivity 1-746290-1 is RoHS non-compliant with vendor-undefined REACH status. For applications requiring regulatory compliance, the 3M component is the appropriate selection.

Q: Do both connectors support the same wire gauge and termination method?

A: Yes. Both connectors support 26-28 AWG ribbon cable with IDC termination, ensuring direct compatibility in ribbon cable applications.

Q: Is the contact type difference between these connectors significant?

A: No. The contact type designation difference (Forked versus Female Socket) does not affect the functional compatibility or electrical performance within the specified parameter set for this connector category.

Q: What is the packaging difference between these parts?

A: The TE Connectivity 1-746290-1 packaging is unspecified in available documentation. The 3M 89160-0001 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
