Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0743370072 is determined by the following critical parameters:

• Connector Configuration: 68-position, stacked, 2-receptacle design
• Mounting Method: Through-hole, right-angle orientation
• Termination Type: Solder connection
• Electrical Interface: SCSI+ / VHDCI compatibility
• Mechanical Features: Board lock and shielding capability
• Contact Material: Gold plating for signal integrity

The TE Connectivity AMP Connectors part 5787962-1 meets these core substitution criteria. Both connectors maintain identical position counts, stacked receptacle architecture, through-hole right-angle mounting, and solder termination. Both feature board lock, shielding, and gold-plated contacts, ensuring functional equivalence for SCSI+ applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5787962-1 is the manufacturer-recommended substitute for the obsolete Molex 0743370072. Selection of this alternative is justified by:

• Product Status Alignment: The substitute is active and currently manufactured, ensuring long-term availability and supply chain continuity.
• Compliance Improvement: The TE Connectivity part achieves ROHS3 compliance, addressing regulatory requirements that the original non-compliant part does not meet.
• Functional Equivalence: Both connectors maintain identical electrical and mechanical specifications for 68-position stacked receptacle SCSI+ applications with through-hole right-angle solder termination.
• Contact Durability: The substitute provides specified gold plating thickness (30.0µin), compared to flash plating on the original, supporting extended operational life.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5787962-1 directly replace the Molex 0743370072 in existing designs?

A: Yes. Both connectors share identical position counts (68, 68), stacked 2-receptacle configuration, through-hole right-angle mounting, and solder termination. The mechanical and electrical interfaces are equivalent for SCSI+ applications.

Q: What is the difference between "Through Hole, Right Angle" and "Panel Mount, Through Hole, Right Angle" mounting?

A: Both mounting types utilize through-hole solder termination with right-angle orientation. Panel mount indicates the connector is designed for direct panel integration, while the original specification does not explicitly designate panel mount. Both are compatible with standard PCB through-hole assembly processes.

Q: Does the gold plating thickness difference affect performance?

A: The TE Connectivity substitute specifies 30.0µin (0.76µm) gold plating versus flash plating on the original. Specified plating thickness provides measurable contact durability and signal integrity benefits, particularly in high-cycle mating applications.

Q: Is the absence of a "Cover" feature on the substitute a compatibility issue?

A: The original part lists "Cover" as a feature; the substitute lists only "Board Lock" and "Shielding." Both connectors provide shielding for EMI protection. Mechanical cover compatibility depends on specific system design requirements and should be evaluated against your application's physical constraints.

Q: What is the inventory status for these parts?

A: The Molex 0743370072 has 927 pieces in stock as new original inventory. The TE Connectivity 5787962-1 has 4,256 pieces in stock. The substitute offers significantly higher availability.
