Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68120-034 is determined by strict equivalence across the following critical parameters:

• Connector type: Ribbon Cable, DIP Header
• Position count: 34 positions
• Cable pitch: 0.050" (1.27mm)
• Board-side pitch: 0.100" (2.54mm)
• Row configuration: 2 rows with 0.100" spacing
• Mounting: Through hole
• Termination method: IDC
• Wire gauge compatibility: 26-28 AWG stranded or solid
• Feed-through capability: Required

All identified substitutes meet these core electrical and mechanical parameters. Variations in contact finish, color, packaging, and compliance status are secondary considerations that do not affect functional interchangeability within the specified parameter set.

Engineering Selection Recommendations

69830-034LF (Amphenol ICC - Direct Manufacturer Equivalent)

The 69830-034LF is the primary substitute for the obsolete 68120-034. Both parts are manufactured by Amphenol ICC and share identical mechanical and electrical specifications. The 69830-034LF is currently in active production status with higher inventory availability. This part achieves RoHS compliance and includes REACH affected status documentation. The contact finish differs in composition (tin versus tin-lead) and thickness (150.0µin versus 100.0µin), but both finishes are suitable for IDC ribbon cable applications. Packaging is supplied in tube format.

746610-8 (TE Connectivity AMP Connectors - Cross-Manufacturer Alternative)

The 746610-8 represents a cross-manufacturer substitute from TE Connectivity's AMP-Latch series. This connector maintains full mechanical and electrical compatibility with identical pitch, position count, and mounting specifications. The wire gauge specification extends to 26-30 AWG for solid conductors, providing broader cable compatibility. The contact finish composition matches the original part (tin-lead) with equivalent thickness. The connector is supplied in black color and bulk packaging. This part remains RoHS non-compliant and REACH unaffected. Selection of this alternative is appropriate when cross-manufacturer sourcing is required or when AMP-Latch series integration is preferred.

Frequently Asked Questions (FAQ)

Q: Can the 69830-034LF directly replace the 68120-034 in existing designs?

A: Yes. The 69830-034LF maintains full mechanical and electrical compatibility with the 68120-034 across all critical parameters: 34 positions, 0.050" cable pitch, 0.100" board-side pitch, 2-row configuration, through-hole mounting, and IDC termination. The differences in contact finish composition and thickness do not affect functional interchangeability in ribbon cable applications.

Q: What is the primary advantage of selecting the 69830-034LF over the 746610-8?

A: The 69830-034LF is manufactured by the same company as the original part (Amphenol ICC) and achieves RoHS compliance, making it the preferred choice for new designs subject to environmental regulations. Both parts are functionally equivalent; the selection depends on compliance requirements and supply chain preferences.

Q: Does the color difference between the 68120-034 (blue) and 746610-8 (black) affect compatibility?

A: No. Color is a cosmetic attribute that does not affect electrical or mechanical performance. Selection between blue and black connectors is determined by application requirements, PCB assembly standards, or visual identification preferences.

Q: Are there wire gauge limitations when substituting with the 746610-8?

A: The 746610-8 accepts 26-28 AWG stranded and 26-30 AWG solid conductors, which encompasses the original specification of 26-28 AWG stranded or solid. This extended solid wire gauge range provides additional flexibility for cable assembly.

Q: What packaging considerations apply to these substitutes?

A: The 69830-034LF is supplied in tube packaging, while the 746610-8 is supplied in bulk packaging. Packaging format may affect handling, storage, and assembly line integration but does not impact connector functionality.

Q: Is the RoHS compliance difference between substitutes significant?

A: RoHS compliance is determined by application requirements and customer specifications. The 69830-034LF is RoHS compliant, making it suitable for applications with environmental compliance mandates. The 746610-8 remains RoHS non-compliant, matching the original part status. Selection should align with end-product regulatory requirements.
