68120-040LF Equivalent & Substitute Parts

Part Overview

The 68120-040LF is a 40-position ribbon cable DIP header connector manufactured by Amphenol ICC (FCI) in the Quickie™ series. This through-hole mounted IDC connector is designed for 26-28 AWG stranded or solid wire termination with a 0.050" cable pitch and 0.100" board-side pitch configuration. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68120-040LF is determined by strict equivalence across the following critical parameters:

• Connector Type: Ribbon Cable, DIP Header
• Number of Positions: 40
• Cable Pitch: 0.050" (1.27mm)
• Board-Side Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Cable Termination: IDC
• Wire Gauge: 26-28 AWG, Stranded or Solid
• Features: Feed Through
• Contact Finish: Tin
• Color: Blue
• Number of Positions Loaded: All
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Both substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the original 68120-040LF.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, providing long-term availability compared to the obsolete 68120-040LF.

The 69830-040LF is manufactured by Amphenol ICC (FCI), the same manufacturer as the original part, and maintains the Quickie™ series designation. This part is RoHS Compliant and REACH Affected, meeting current environmental compliance requirements. The contact finish thickness is 150.0µin (3.81µm), which exceeds the original specification of 100.0µin (2.54µm).

The 1-1658525-3 is manufactured by TE Connectivity AMP Connectors and belongs to the 622 series. This part is ROHS3 Compliant and maintains the original contact finish thickness of 100.0µin (2.54µm). REACH status is listed as Vendor Undefined.

Both parts are electrically and mechanically equivalent to the 68120-040LF across all critical parameters. Selection between them should be based on procurement availability, packaging requirements (Tube versus Bulk), and compliance certifications applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 69830-040LF and 1-1658525-3 be used interchangeably with the 68120-040LF?

A: Yes. Both substitute parts meet all electrical and mechanical specifications of the 68120-040LF, including connector type, position count, pitch dimensions, mounting configuration, termination method, and wire gauge compatibility.

Q: What is the difference in contact finish thickness between the parts?

A: The 68120-040LF and 1-1658525-3 both specify 100.0µin (2.54µm) contact finish thickness. The 69830-040LF specifies 150.0µin (3.81µm). This difference does not affect electrical or mechanical interchangeability.

Q: Why is the 68120-040LF listed as obsolete?

A: The 68120-040LF has been discontinued by the manufacturer. The 69830-040LF and 1-1658525-3 are active products with current production and ongoing availability.

Q: What packaging options are available?

A: The 69830-040LF is supplied in Tube packaging. The 1-1658525-3 is supplied in Bulk packaging. Packaging selection should align with procurement and assembly requirements.

Q: Are there compliance differences between the substitutes?

A: The 69830-040LF is RoHS Compliant and REACH Affected. The 1-1658525-3 is ROHS3 Compliant with Vendor Undefined REACH status. Compliance requirements should be evaluated based on the end application and regulatory jurisdiction.
