Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68120-040 is determined by strict alignment with the following critical parameters:

• Connector Type: Must be Ribbon Cable, DIP Header configuration
• Position Count: Exactly 40 positions required
• Cable Pitch: 0.050" (1.27mm) mandatory
• Board-Side Pitch: 0.100" (2.54mm) mandatory
• Row Configuration: 2 rows with 0.100" (2.54mm) spacing
• Mounting: Through-hole only
• Termination Method: IDC (Insulation Displacement Contact)
• Wire Gauge Compatibility: 26-28 AWG stranded or solid acceptable
• Contact Finish: Tin-Lead plating with 100.0µin (2.54µm) thickness

The substitute part 746610-9 (TE Connectivity AMP Connectors, AMP-Latch series) meets all critical electrical and mechanical parameters, with wire gauge compatibility extended to 26-30 AWG solid conductor support.

Parameter Comparison

Engineering Selection Recommendations

The 68120-040 (Amphenol ICC, Quickie™ series) is RoHS non-compliant. The substitute part 746610-9 (TE Connectivity, AMP-Latch series) is ROHS3 compliant and REACH unaffected, providing regulatory advantage for applications subject to environmental compliance requirements. Both parts maintain identical electrical and mechanical specifications for the critical parameters governing IDC ribbon cable connector functionality. Selection between these parts should be based on regulatory compliance requirements, supply availability, and design certification status. The 746610-9 offers extended wire gauge support for solid conductors (26-30 AWG versus 26-28 AWG), providing additional flexibility for cable assembly specifications.

Frequently Asked Questions (FAQ)

Q: Can 746610-9 be used as a direct replacement for 68120-040?

A: Yes. Both connectors share identical pitch specifications (0.050" cable pitch, 0.100" board-side pitch), 40-position configuration, 2-row layout, through-hole mounting, and IDC termination method. The contact finish, finish thickness, and feed-through features are equivalent.

Q: What is the primary difference between these two parts?

A: The 746610-9 is ROHS3 compliant and REACH unaffected, while the 68120-040 is RoHS non-compliant. Additionally, the 746610-9 supports 26-30 AWG solid wire gauge, compared to the 68120-040's 26-28 AWG specification.

Q: Are there color differences between these connectors?

A: Yes. The 68120-040 is blue, while the 746610-9 is black. Color does not affect electrical or mechanical compatibility but may be relevant for assembly identification or design aesthetics.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling.

Q: Can I use these connectors with different wire gauges?

A: The 68120-040 accepts 26-28 AWG stranded or solid wire. The 746610-9 accepts 26-28 AWG stranded wire and 26-30 AWG solid wire. Wire gauge must fall within the specified range for proper IDC termination.

Q: Are both parts suitable for feed-through applications?

A: Yes. Both connectors feature feed-through capability, allowing signal or power pass-through across the connector assembly.
