Amphenol ICC 68020-672 Rectangular Connector Header – Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68020-672 is a through-hole, right-angle rectangular connector header with 72 positions at 0.100" (2.54mm) pitch, designed for board-to-board applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support, design updates, and inventory management. Active substitute parts maintain the core electrical and mechanical specifications required for direct replacement in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68020-672 is determined by strict alignment with the following core parameters:

• Connector Configuration: 72-position, 2-row header at 0.100" (2.54mm) pitch
• Mounting and Orientation: Through-hole, right-angle mounting
• Contact System: Male pin, solder termination
• Electrical Performance: 3A per contact current rating
• Environmental Compliance: UL94 V-0 flammability rating, MSL 1

The two substitute parts listed below meet these criteria and are classified as active products with current manufacturing status. Both maintain mechanical compatibility and electrical performance specifications suitable for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Preci-Dip 802-V3-072-20-001101 is the primary recommended substitute. This part maintains full compatibility with the 68020-672 across all critical parameters: 72-position, 2-row configuration at 0.100" pitch, through-hole right-angle mounting, and 3A per contact current rating. The operating temperature range (-55°C ~ 125°C) covers the lower end of the original specification. ROHS3 compliance and active product status ensure long-term availability and regulatory alignment for new designs.

Harwin Inc. M20-9743646 serves as a secondary substitute option. This part meets all core mechanical and electrical requirements and is actively manufactured. The operating temperature range (-40°C ~ 105°C) is narrower than the original specification and should be evaluated against application requirements. ROHS3 compliance and cuttable header design provide additional flexibility for certain applications. Tin contact finish differs from the gold finish of the original part.

Both substitutes carry MSL 1 rating and UL94 V-0 flammability certification, ensuring compatibility with standard PCB assembly processes and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the Preci-Dip 802-V3-072-20-001101 be used as a direct replacement for the 68020-672?

A: Yes. Both parts share identical 72-position, 2-row configuration at 0.100" (2.54mm) pitch, through-hole right-angle mounting, and 3A per contact current rating. The Preci-Dip part is actively manufactured and ROHS3 compliant, making it suitable for direct PCB layout replacement.

Q: What is the difference between the contact shapes in these parts?

A: The 68020-672 features square contacts, while the Preci-Dip 802-V3-072-20-001101 uses circular contacts. Both contact geometries are compatible with standard 0.100" pitch mating connectors and do not affect electrical performance or mechanical fit in typical board-to-board applications.

Q: Does the Harwin M20-9743646 have a narrower operating temperature range?

A: Yes. The Harwin part operates from -40°C ~ 105°C, compared to the original -65°C ~ 125°C range. Applications requiring operation below -40°C or above 105°C should use the Preci-Dip substitute or verify Harwin part suitability against specific thermal requirements.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the Preci-Dip 802-V3-072-20-001101 and Harwin M20-9743646 are ROHS3 compliant. The original 68020-672 is RoHS non-compliant, making these substitutes necessary for designs requiring regulatory compliance.

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

A: The 68020-672 uses gold or gold GXT™ finish. The Preci-Dip substitute uses gold finish on mating contacts. The Harwin substitute uses tin finish on both mating and post contacts. Gold finishes provide superior corrosion resistance; tin finishes are suitable for standard applications with adequate environmental protection.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application does not depend on specific contact geometry or finish properties. Both substitutes maintain the same pitch, position count, mounting style, and current rating. PCB layouts and mating connector selections require no modification.
