Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 746288-5 are identified based on strict electrical and mechanical parameter compatibility. The following parameters must align for a part to function as a direct substitute:

• Connector type (Receptacle)
• Number of positions (24)
• Pitch spacing (0.100" / 2.54mm)
• Row configuration (2 rows with 0.100" spacing)
• Cable termination method (IDC)
• Wire type (Ribbon Cable)
• Wire gauge range (26-28 AWG)
• Mounting configuration (Free Hanging, In-Line)
• Presence of feed-through and polarizing key features
• Contact finish thickness (30.0µin / 0.76µm)
• Moisture sensitivity level (1 - Unlimited)

All substitute parts listed meet these core parameters and are therefore mechanically and electrically compatible with applications designed for the 746288-5.

Parameter Comparison

Engineering Selection Recommendations

1658622-5 (TE Connectivity AMP Connectors)

The 1658622-5 is a direct substitute manufactured by TE Connectivity within the same AMP-Latch series. This part maintains identical mechanical and electrical specifications to the 746288-5 while offering active product status. The 1658622-5 is RoHS Compliant, addressing environmental regulatory requirements that the obsolete 746288-5 does not meet. Contact finish is specified as Gold or Gold-Palladium, both meeting the 30.0µin thickness requirement. This substitute is suitable for new designs and production transitions from the obsolete 746288-5.

89124-0101 (3M)

The 89124-0101 is a similar substitute from 3M within the 891 series. This part meets all core mechanical and electrical parameters required for functional compatibility with the 746288-5. The 89124-0101 is ROHS3 Compliant and REACH Unaffected, providing enhanced regulatory compliance. The contact type differs (Female Socket versus Forked), and the connector color is Gray rather than Black. This substitute is suitable for applications where cross-manufacturer compatibility is acceptable and regulatory compliance is a priority.

Both substitute parts are currently in active production status with substantial inventory availability, ensuring supply chain continuity for the obsolete 746288-5.

Frequently Asked Questions (FAQ)

Q: Can the 1658622-5 be used as a direct replacement for the 746288-5 in existing designs?

A: Yes. The 1658622-5 maintains identical pitch, row spacing, position count, IDC termination method, wire gauge range, and feature set as the 746288-5. Both are TE Connectivity AMP-Latch series connectors with matching mechanical and electrical specifications.

Q: What is the difference between the contact types (Forked versus Female Socket) in the 89124-0101?

A: Both contact types are designed for IDC ribbon cable termination and function within the same 0.100" pitch configuration. The contact type difference reflects design variation between manufacturers but does not affect compatibility with standard 26-28 AWG ribbon cable or mating connector specifications.

Q: Does the 1658622-5 offer improved compliance compared to the 746288-5?

A: Yes. The 1658622-5 is RoHS Compliant, whereas the 746288-5 is RoHS non-compliant. For applications subject to RoHS regulations, the 1658622-5 is the appropriate selection.

Q: Are there packaging differences between the substitute parts?

A: The 1658622-5 and 89124-0101 are supplied in Bulk packaging. Packaging specifications should be confirmed with procurement requirements for your application.

Q: Can the 89124-0101 be used in applications originally designed for the 746288-5?

A: Yes. The 89124-0101 meets all core mechanical and electrical parameters: 24 positions, 0.100" pitch, 2-row configuration, IDC termination, 26-28 AWG wire gauge, feed-through and polarizing key features, and matching contact finish thickness. The cross-manufacturer substitution is functionally valid.

Q: What is the significance of the contact finish options (Gold versus Gold-Palladium) in the 1658622-5?

A: Both Gold and Gold-Palladium finishes meet the specified 30.0µin (0.76µm) thickness requirement. The contact finish option does not affect electrical or mechanical compatibility with the 746288-5 specification.

Q: Why is the 746288-5 classified as obsolete?

A: The 746288-5 is no longer in active production. The 1658622-5 and 89124-0101 are current production alternatives that meet the same functional requirements.
