Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 746288-2 are identified based on strict electrical and mechanical parameter compatibility. The following parameters must match or be compatible for substitution:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 14
• 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
• Features: Feed Through, Polarizing Key
• Mounting Type: Free Hanging (In-Line)
• Contact Finish Thickness: 30.0µin (0.76µm)
• Moisture Sensitivity Level: 1 (Unlimited)

Two substitute parts meet these criteria and are classified as either direct manufacturer equivalents or similar cross-manufacturer alternatives. Both substitute parts maintain full compatibility with the electrical and mechanical specifications of the original 746288-2 connector.

Engineering Selection Recommendations

TE Connectivity AMP Connectors 1658622-2 (Direct Equivalent)

The 1658622-2 is the primary substitute for the obsolete 746288-2. Both connectors are manufactured by TE Connectivity within the AMP-Latch series and maintain identical electrical and mechanical specifications. The 1658622-2 is classified as an active product with current manufacturing support and availability. This part achieves RoHS Compliance status, whereas the original 746288-2 is RoHS non-compliant. The contact finish specification allows for Gold or Gold-Palladium composition while maintaining the required 30.0µin (0.76µm) thickness. The 1658622-2 is suitable for direct replacement in new designs and field applications requiring RoHS-compliant components.

3M 89114-0101 (Cross-Manufacturer Alternative)

The 89114-0101 provides a cross-manufacturer substitute from 3M within the 891 series. This connector maintains all critical electrical and mechanical parameters including 14 positions, 0.100" pitch, 2-row configuration, IDC termination, and 26-28 AWG ribbon cable compatibility. The contact type differs as a Female Socket design rather than Forked, though both contact types are compatible with standard IDC ribbon cable termination. The 89114-0101 is classified as an active product with ROHS3 Compliance and REACH Unaffected status. The connector housing color is gray rather than black. This part is suitable for applications where cross-manufacturer sourcing is acceptable and provides an alternative supply channel.

Both substitute parts are available in active production status, ensuring supply chain continuity and eliminating obsolescence risk associated with the original 746288-2.

Frequently Asked Questions (FAQ)

Q: Can the 1658622-2 be used as a direct replacement for the 746288-2 in existing applications?

A: Yes. The 1658622-2 maintains identical electrical and mechanical specifications including connector type, position count, pitch, row spacing, IDC termination method, wire gauge, and contact finish thickness. Both connectors are compatible with the same ribbon cable and mating plug connectors. The primary difference is product status: the 1658622-2 is active production while the 746288-2 is obsolete.

Q: What is the difference between the contact types in the 746288-2 and 89114-0101?

A: The 746288-2 uses a Forked contact design, while the 89114-0101 uses a Female Socket contact design. Both contact types are compatible with IDC ribbon cable termination and maintain the same electrical performance characteristics. The contact type difference does not affect functional compatibility in IDC applications.

Q: Are there RoHS compliance differences between the substitute parts and the original?

A: Yes. The original 746288-2 is RoHS non-compliant. The 1658622-2 is RoHS Compliant, and the 89114-0101 is ROHS3 Compliant. If RoHS compliance is required for your application, either substitute part is suitable. If RoHS non-compliance is specifically required, the original 746288-2 must be used.

Q: Does the color difference between the 746288-2 (black) and 89114-0101 (gray) affect compatibility?

A: No. Color is a cosmetic characteristic and does not affect electrical or mechanical compatibility. Both connectors function identically in circuit applications. Color selection may be relevant only for visual identification or aesthetic requirements in specific applications.

Q: What is the contact finish difference between Gold and Gold-Palladium in the 1658622-2?

A: The 1658622-2 specification allows for either Gold or Gold-Palladium contact finish composition. Both options maintain the required 30.0µin (0.76µm) thickness specification. The actual finish composition supplied depends on manufacturing lot and availability. Both finishes provide equivalent electrical performance and corrosion resistance for IDC ribbon cable applications.

Q: Are all three connectors compatible with the same ribbon cable?

A: Yes. All three connectors (746288-2, 1658622-2, and 89114-0101) accept 26-28 AWG ribbon cable with IDC termination. The 0.100" (2.54mm) pitch and 2-row configuration are identical across all parts, ensuring mechanical and electrical compatibility with the same ribbon cable assemblies.

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

A: The 1658622-2 has 3457 pieces in stock, the 89114-0101 has 1564 pieces in stock, and the original 746288-2 has 775 pieces in stock. Both substitute parts offer superior inventory availability compared to the obsolete original part, reducing lead time risk for production and field replacement requirements.
