Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity AMP Connectors 1658622-7

The 1658622-7 is the direct equivalent substitute for the obsolete 746288-7. Both parts are manufactured by TE Connectivity within the AMP-Latch series and share identical mechanical and electrical specifications. The 1658622-7 is currently in active production status with ROHS3 compliance, providing superior supply chain availability and regulatory alignment for new designs and ongoing production requirements.

Secondary Recommendations: Amphenol ICC 66900-230LF and 3M 89130-0101

Both the Amphenol ICC 66900-230LF and 3M 89130-0101 provide functional equivalence as 30-position IDC ribbon cable receptacle connectors with matching pitch, row configuration, and mounting specifications. These alternatives are suitable for applications where cross-manufacturer sourcing is acceptable.

The 66900-230LF operates with 28-30 AWG wire gauge (compared to the primary specification of 26-28 AWG) and includes integrated strain relief. The 89130-0101 maintains the exact 26-28 AWG wire gauge specification and is ROHS3 compliant with REACH unaffected status.

Compliance Considerations:

All substitute parts are RoHS compliant (ROHS3 or equivalent), addressing regulatory requirements that the original 746288-7 does not meet. Selection should account for system-level compliance requirements and environmental regulations applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 1658622-7 directly replace the 746288-7 in existing designs?

A: Yes. The 1658622-7 is a direct equivalent with identical pitch (0.100"), position count (30), row configuration (2 rows), IDC termination, and ribbon cable compatibility. Both parts are TE Connectivity AMP-Latch series connectors with matching mechanical and electrical specifications.

Q: What is the difference between the contact types (Forked vs. Female Socket)?

A: The 746288-7 and 1658622-7 use forked contacts, while the 66900-230LF and 89130-0101 use female socket contacts. Both contact designs are compatible with standard IDC ribbon cable termination and provide equivalent electrical performance in this connector category. Contact type selection depends on mating connector design and application requirements.

Q: Are there wire gauge compatibility differences between substitutes?

A: The primary specification is 26-28 AWG. The 1658622-7 and 89130-0101 maintain this specification. The 66900-230LF operates with 28-30 AWG wire gauge, which overlaps the upper range of the primary specification. Verify ribbon cable gauge compatibility with your specific application before selection.

Q: What is the significance of the Gold-Palladium contact finish option on the 1658622-7?

A: The 1658622-7 is available with either gold or gold-palladium contact finish, both at 30.0µin (0.76µm) thickness. This matches the original 746288-7 specification. Gold-palladium provides equivalent electrical performance and corrosion resistance for IDC applications.

Q: Does the strain relief feature on the 66900-230LF affect compatibility?

A: The integrated strain relief on the 66900-230LF is an additional feature that does not affect electrical or mechanical compatibility. It provides enhanced cable retention and mechanical durability. This feature is compatible with standard ribbon cable IDC termination.

Q: What are the RoHS compliance implications for substitution?

A: The original 746288-7 is RoHS non-compliant. All substitute parts (1658622-7, 66900-230LF, and 89130-0101) are RoHS compliant. For new designs or systems subject to RoHS regulations, substitute parts are required. For legacy system maintenance, compliance requirements depend on applicable regulations and customer specifications.

Q: Are all substitute parts available in the same packaging formats?

A: Packaging differs by manufacturer. The 1658622-7 is supplied in bulk packaging, the 66900-230LF in tube packaging, and the 89130-0101 in bulk packaging. Packaging selection affects inventory management and component handling but does not affect electrical or mechanical performance.

Q: Can I use the 66900-230LF with 26 AWG ribbon cable?

A: The 66900-230LF is specified for 28-30 AWG wire gauge. While 28 AWG falls within both the primary specification (26-28 AWG) and the 66900-230LF specification (28-30 AWG), 26 AWG is outside the 66900-230LF rated range. Use the 1658622-7 or 89130-0101 for guaranteed 26 AWG compatibility.

Q: What is the REACH status difference between substitutes?

A: The 1658622-7 has vendor undefined REACH status. The 66900-230LF is REACH affected. The 89130-0101 is REACH unaffected. For applications subject to REACH regulations, the 89130-0101 provides the clearest regulatory status. Verify specific REACH requirements with your regulatory or procurement department.
