Amphenol ICC 68710-175 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68710-175 is a rectangular connector header designed for through-hole mounting applications. This component features a 40-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, suitable for board-to-cable and board-to-board interconnections. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 68710-175 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 40 positions arranged in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole mounting with press-fit and solder termination capability
• Shrouding Design: 4-wall shrouded configuration
• Contact Finish: Gold plating on mating surfaces
• Flammability Compliance: UL94 V-0 rating

The 3M 3432-650T02TC meets all critical substitution criteria. This part maintains identical position count, pitch spacing, mounting method, and shrouding configuration. Both components support press-fit and solder termination and feature gold-plated mating contacts with UL94 V-0 flammability compliance.

Parameter Comparison

Engineering Selection Recommendations

The 3M 3432-650T02TC is the primary substitute for the obsolete Amphenol ICC 68710-175. This substitution is supported by:

• Active Product Status: The 3M part is currently in active production, ensuring long-term availability and supply chain stability.
• Compliance Alignment: Both parts maintain UL94 V-0 flammability compliance and identical ECCN/HTSUS classifications.
• Mechanical & Electrical Equivalence: Identical pitch, position count, row configuration, mounting method, and contact finish specifications ensure direct functional compatibility.
• RoHS Compliance Improvement: The 3M substitute achieves RoHS compliance, providing environmental and regulatory advantages for new designs or redesigns.

Physical dimensions show minor variations in contact length and insulation height between the two parts. The 3M 3432-650T02TC exhibits slightly longer overall contact length (0.715" vs. 0.625") and insulation height (0.680" vs. 0.640"), which may require PCB layout verification for existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 3M 3432-650T02TC be used as a direct drop-in replacement for the Amphenol ICC 68710-175?

A: The 3M part is mechanically and electrically compatible based on pitch, position count, row spacing, and contact configuration. However, the slightly larger overall dimensions (contact length and insulation height) require verification against existing PCB layouts and mating connector specifications before implementation.

Q: What is the primary reason for seeking a substitute for the Amphenol ICC 68710-175?

A: The Amphenol ICC 68710-175 is classified as obsolete. The 3M 3432-650T02TC provides an active, currently manufactured alternative that maintains functional equivalence.

Q: Are there differences in contact material between these parts?

A: Yes. The Amphenol ICC 68710-175 uses Phosphor Bronze Alloy contacts, while the 3M 3432-650T02TC uses Copper Alloy contacts. Both materials support the specified gold plating and electrical performance requirements.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: The 3M part's RoHS compliance is an advantage for new designs and regulatory requirements. For existing designs using the non-compliant Amphenol part, substitution is still functionally valid but may trigger design review processes depending on organizational compliance policies.

Q: What are the dimensional considerations for substitution?

A: The 3M 3432-650T02TC has a contact length of 0.240" (6.10mm) compared to 0.230" (5.84mm) for the Amphenol part, and insulation height of 0.680" (17.27mm) compared to 0.640" (16.26mm). These differences must be evaluated against PCB thickness, mating connector depth, and available board space.

Q: Are the insulation materials compatible?

A: Both parts use glass-filled polyester-based insulation materials. The Amphenol part specifies Polyester, Glass Filled, while the 3M part specifies Polycyclohexylenedimethylene Terephthalate (PCT), Polyester, Glass Filled. Both achieve UL94 V-0 flammability compliance.
