Engineering Selection Recommendations

TE Connectivity AMP Connectors 1658622-6 (Direct Substitute)

The 1658622-6 is the primary substitute for the obsolete 746288-6. Both connectors are manufactured by TE Connectivity within the AMP-Latch series and share identical mechanical and electrical specifications. The 1658622-6 is classified as an active product, ensuring ongoing availability and supply chain support. This part achieves RoHS Compliance, providing regulatory advantage over the non-compliant 746288-6. The contact finish specification allows for Gold or Gold-Palladium composition, both meeting the required 30.0µin thickness. Selection of the 1658622-6 is recommended for new designs and production continuity.

3M 89126-0101 (Similar Substitute)

The 89126-0101 provides functional equivalence through matching all critical electrical and mechanical parameters. This connector is manufactured by 3M within the 891 series and maintains active product status. The 89126-0101 achieves ROHS3 Compliance and carries REACH Unaffected certification, providing enhanced regulatory documentation. The contact type differs as Female Socket rather than Forked; however, both configurations are functionally equivalent for IDC ribbon cable termination at the specified wire gauge and pitch. The connector housing color is Gray rather than Black, which does not affect electrical performance. Selection of the 89126-0101 is appropriate when supply constraints on TE Connectivity parts exist or when enhanced regulatory compliance documentation is required.

Frequently Asked Questions (FAQ)

Q: Can the 1658622-6 be used as a direct replacement for the 746288-6 in existing assemblies?

A: Yes. The 1658622-6 matches all critical parameters including connector type, position count, pitch, row spacing, IDC termination method, wire gauge, and contact finish thickness. Both are AMP-Latch series receptacles designed for 26-28 AWG ribbon cable. The 1658622-6 is the recommended direct substitute.

Q: What is the difference between the forked contact type in the 746288-6 and the female socket contact type in the 89126-0101?

A: Both contact types are designed for IDC termination with ribbon cable and function equivalently at the specified wire gauge and pitch. The contact type difference does not affect mechanical or electrical compatibility for this application.

Q: Are there compliance differences between the substitute parts?

A: Yes. The 746288-6 is RoHS non-compliant with vendor-undefined REACH status. The 1658622-6 is RoHS Compliant with vendor-undefined REACH status. The 89126-0101 is ROHS3 Compliant with REACH Unaffected certification. Selection should consider applicable regulatory requirements for the end application.

Q: Does the connector housing color difference between the 746288-6 (Black) and 89126-0101 (Gray) affect performance?

A: No. Housing color is a cosmetic parameter and does not affect electrical performance, mechanical fit, or functional compatibility. Both colors are suitable for the same applications.

Q: What is the significance of the contact finish composition difference between Gold and Gold-Palladium in the 1658622-6?

A: Both Gold and Gold-Palladium finishes meet the specified thickness requirement of 30.0µin (0.76µm). The composition variation does not affect electrical performance or mechanical compatibility for IDC ribbon cable applications.

Q: Are all three connectors compatible with the same mating plugs?

A: Yes. All three connectors share identical pitch (0.100"), row spacing (0.100"), position count (26), and row configuration (2 rows). They are mechanically compatible with the same mating plug connectors designed for these specifications.

Q: What inventory availability should be considered when selecting a substitute?

A: The 1658622-6 has 1425 pieces in stock. The 89126-0101 has 26950 pieces in stock. The original 746288-6 has 825 pieces in stock but is obsolete. For long-term supply assurance, the 89126-0101 offers the highest inventory level.

Q: Can the 746288-6 be intermixed with substitute parts in the same assembly?

A: Yes. All three connectors meet identical electrical and mechanical specifications for the critical parameters governing IDC ribbon cable termination. Intermixing is functionally acceptable within the same assembly.
