Amphenol ICC 68710-133 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68710-133 is a vertical through-hole rectangular connector header with 30 positions at 2.54mm pitch, designed for board-to-cable/wire applications. This component features shrouded 4-wall construction with press-fit and solder termination options, gold-plated mating contacts, and phosphor bronze alloy construction. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 68710-133 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Pitch - mating: 0.100" (2.54mm)
• Number of positions: 30
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Press-Fit, Solder
• Contact finish - mating: Gold
• Insulation material: Polyester or compatible glass-filled polymer
• Material flammability rating: UL94 V-0

The 3M 3440-660T02TC meets all critical parameters and qualifies as a direct functional substitute. Minor variations in contact length, insulation height, and post finish do not affect board-level compatibility or mating performance.

Parameter Comparison

Engineering Selection Recommendations

The 3M 3440-660T02TC is the qualified substitute for the obsolete Amphenol ICC 68710-133. Selection is based on the following engineering criteria:

Product Status: The Amphenol ICC 68710-133 is obsolete. The 3M 3440-660T02TC is active and in production, ensuring long-term availability and supply chain continuity.

Compliance and Certifications: Both components carry UL94 V-0 flammability ratings and share identical ECCN and HTSUS classifications. The 3M substitute achieves RoHS compliance, whereas the original part is RoHS non-compliant. This compliance advantage supports modern procurement requirements and environmental regulations.

Electrical and Mechanical Compatibility: The substitute maintains identical mating pitch (2.54mm), position count (30), row configuration (2), shrouding type (4-wall), and termination methods (press-fit and solder). Contact geometry, finish specification (gold mating surface), and keying features are functionally equivalent.

Physical Dimensions: Minor increases in contact length (0.010" / 0.26mm) and insulation height (0.040" / 1.01mm) do not compromise board-level integration or mating performance. These dimensional variations fall within standard connector design tolerances and do not affect PCB layout or cable assembly compatibility.

Material Composition: The substitute uses copper alloy contacts with tin-lead post finish instead of phosphor bronze with unspecified post finish. Both material systems provide equivalent electrical performance and reliability for standard through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the 3M 3440-660T02TC directly replace the Amphenol ICC 68710-133 on existing PCBs?

A: Yes. The substitute maintains identical mating pitch, position count, row spacing, shrouding configuration, and mounting type. PCB footprints designed for the original part accommodate the substitute without modification.

Q: What is the significance of the dimensional differences in contact length and insulation height?

A: The 3M substitute has slightly longer overall contact length (0.715" vs. 0.625") and greater insulation height (0.680" vs. 0.640"). These differences do not affect mating performance or board-level clearance in standard applications. Verify clearance in designs with tight vertical constraints.

Q: Does the change from phosphor bronze to copper alloy contacts affect performance?

A: No. Both contact materials provide equivalent electrical conductivity and reliability for standard through-hole connector applications. The copper alloy in the substitute is a standard material for this connector category.

Q: Why is RoHS compliance important for this substitution?

A: The original part is RoHS non-compliant, while the substitute is RoHS compliant. RoHS compliance is required for many modern procurement specifications and supports environmental regulations. Use the substitute for new designs and applications subject to RoHS requirements.

Q: Are there any termination differences between the original and substitute?

A: Both components support press-fit and solder termination. The substitute includes tin-lead post finish (100.0µin thickness) compared to the original's unspecified post finish. This provides enhanced solderability and corrosion resistance.

Q: What is the inventory status of the substitute?

A: The 3M 3440-660T02TC is active and in production with 1020 pieces in stock. The original Amphenol ICC part is obsolete with limited remaining inventory (1022 pieces).

Q: Are there additional cross-reference part numbers for the 3M substitute?

A: Yes. The 3M 3440-660T02TC has documented substitutes including N3440-6002RB. Consult 3M documentation for complete cross-reference information.
