Amphenol ICC 68020-172 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68020-172 is a rectangular connector header, right-angle mounted, with 72 positions at 0.100" (2.54mm) pitch. This through-hole component is designed for board-to-board connections with solder termination and push-pull fastening. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68020-172 is determined by the following critical parameters:

• Position Count & Row Configuration: 72 positions in 2 rows at 0.100" (2.54mm) pitch
• Mounting & Termination: Through-hole, right-angle, solder-terminated
• Contact Type & Fastening: Male pin headers with push-pull fastening
• Electrical Performance: 3A per contact current rating, UL94 V-0 flammability rating
• Environmental Range: Operating temperature compatibility

The substitute parts are grouped as follows:

Group 1 - Direct Equivalents (72 Position, 2 Row)

• Preci-Dip 802-V3-072-20-001101
• Harwin Inc. M20-9743646

Group 2 - Position Variant (80 Position, 2 Row)

• TE Connectivity AMP Connectors 9-103801-0

The 80-position variant (Group 2) provides additional contact positions but maintains the same pitch, row spacing, and electrical characteristics, allowing use in applications where the extra positions do not conflict with board layout constraints.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (72 Positions):

The Preci-Dip 802-V3-072-20-001101 and Harwin Inc. M20-9743646 are functionally equivalent to the 68020-172 in position count and row configuration. Both substitute parts are active products with ROHS3 compliance, addressing the obsolescence and regulatory status of the original component. The Preci-Dip part maintains gold mating contact finish consistent with the original specification, while the Harwin part uses tin finish. Both meet the 3A current rating and UL94 V-0 flammability requirement.

For Position-Variant Applications (80 Positions):

The TE Connectivity AMP Connectors 9-103801-0 provides 80 positions instead of 72, maintaining identical pitch and row spacing. This part is suitable only for applications where the additional 8 contact positions do not create board layout conflicts. The part is active and ROHS3 compliant with gold mating contact finish and equivalent electrical performance.

Compliance Considerations:

All substitute parts are ROHS3 compliant, addressing regulatory requirements absent in the obsolete original part. Selection should prioritize active products with established supply chains and compliance certifications appropriate to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 80-position TE Connectivity part replace the 72-position Amphenol part directly?

A: The 80-position variant maintains the same 0.100" (2.54mm) pitch and row spacing, but the additional 8 contact positions extend the overall connector length. Direct substitution is possible only if the PCB layout accommodates the larger footprint and the extra positions do not interfere with adjacent components or traces.

Q: What is the difference between the Preci-Dip and Harwin 72-position substitutes?

A: Both maintain 72 positions, 2 rows, and 0.100" (2.54mm) pitch. The Preci-Dip part uses gold mating contact finish and brass contact material with a circular contact shape. The Harwin part uses tin mating contact finish and brass contact material with a square contact shape. The Preci-Dip part operates to -55°C minimum, while the Harwin part operates to -40°C minimum. Both meet the 3A current rating and UL94 V-0 flammability requirement.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original Amphenol ICC 68020-172 is RoHS non-compliant, making the compliant substitutes necessary for applications subject to RoHS regulations.

Q: What is the moisture sensitivity level for these connectors?

A: All parts, including the original and substitutes, have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: Can contact finish differences affect performance?

A: Contact finish affects corrosion resistance and mating force characteristics. Gold finish (Preci-Dip and TE Connectivity parts) provides superior corrosion resistance compared to tin finish (Harwin part). Selection should consider the application environment and mating cycle requirements.
