TE Connectivity AMP Connectors 746290-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 746290-6 is a 26 Position Rectangular Receptacle Connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable in the 26-28 AWG wire gauge range. This connector features gold-plated forked contacts, a 0.100" (2.54mm) pitch configuration, and feed-through mounting capability in a 2-row arrangement.

The 746290-6 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 746290-6 are identified based on strict electrical and mechanical parameter compatibility. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 26
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Gauge: 26-28 AWG
• Wire Type: Ribbon Cable
• Mounting Type: Free Hanging (In-Line)
• Contact Finish Thickness: 30.0µin (0.76µm)
• Features: Feed Through

Substitute parts must maintain identical mechanical footprint, electrical interface, and termination methodology. Contact type variations (forked versus female socket) and contact finish material variations (gold versus gold-palladium) are permissible within the specified finish thickness tolerance. Color differences do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

1658623-6 (Direct Substitute - TE Connectivity AMP Connectors)

The 1658623-6 is the primary direct substitute for the obsolete 746290-6. Both connectors are manufactured by TE Connectivity within the AMP-Latch series and maintain identical mechanical and electrical specifications. The 1658623-6 carries active product status with ROHS3 compliance, providing long-term supply chain viability. The contact finish specification permits gold or gold-palladium composition while maintaining the required 30.0µin (0.76µm) thickness. Current inventory availability is 8697 pieces.

89126-0001 (Similar Substitute - 3M)

The 89126-0001 is a functionally equivalent alternative manufactured by 3M within the 891 series. This connector maintains all critical mechanical and electrical parameters including pitch, row configuration, IDC termination, wire gauge compatibility, and feed-through mounting. The contact type differs (female socket versus forked), and the connector color is gray rather than black. The 89126-0001 carries active product status with ROHS3 compliance. Current inventory availability is 1863 pieces.

Both substitute parts eliminate the supply risk associated with the obsolete 746290-6 status while maintaining full electrical and mechanical compatibility with existing mating connectors and cable assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 1658623-6 directly replace the 746290-6 in existing applications?

A: Yes. The 1658623-6 maintains identical pitch (0.100"), row configuration (2 rows at 0.100" spacing), position count (26), IDC termination method, wire gauge range (26-28 AWG), and feed-through mounting characteristics. Both connectors accept ribbon cable with identical mechanical and electrical interface specifications.

Q: What is the difference between the contact types in the 746290-6 and 89126-0001?

A: The 746290-6 uses forked contacts, while the 89126-0001 uses female socket contacts. Both contact types are designed for IDC termination and maintain the same electrical performance within the specified wire gauge range. The contact type difference does not affect compatibility with standard ribbon cable assemblies or mating connectors designed for 0.100" pitch, 26-position receptacle interfaces.

Q: Does the color difference between the 746290-6 (black) and 89126-0001 (gray) affect functionality?

A: No. Color is a cosmetic parameter and does not affect electrical performance, mechanical fit, or termination characteristics. The color difference reflects manufacturer design standards and does not impact connector functionality or compatibility.

Q: Are there RoHS compliance considerations when substituting the 746290-6?

A: The 746290-6 is RoHS non-compliant. Both substitute parts (1658623-6 and 89126-0001) are ROHS3 compliant. If the application requires RoHS compliance, either substitute part is suitable. If the application operates under legacy non-compliant specifications, both substitutes remain functionally compatible.

Q: What is the significance of the contact finish specification (30.0µin)?

A: The contact finish thickness of 30.0µin (0.76µm) is a critical specification that ensures consistent electrical contact resistance and corrosion resistance across all three connectors. All substitute parts maintain this specification, ensuring equivalent performance in signal integrity and long-term reliability.

Q: Can the 1658623-6 and 89126-0001 be used interchangeably in the same application?

A: Yes. Both connectors maintain identical mechanical footprint, pitch, row spacing, position count, IDC termination method, wire gauge compatibility, and feed-through mounting. The differences in contact type (forked versus female socket) and color do not prevent interchangeability with standard ribbon cable assemblies and mating connectors designed for this connector class.

Q: What inventory considerations should guide part selection?

A: The 1658623-6 has current inventory of 8697 pieces, while the 89126-0001 has 1863 pieces. For applications requiring immediate availability or high-volume procurement, the 1658623-6 offers greater stock depth. Both parts carry active product status, ensuring continued availability for future requirements.
