Amphenol ICC 68021-172 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68021-172 is a rectangular connector header, right-angle configuration, with 72 positions at 2.54mm pitch. This through-hole, board-to-board connector features male pins with gold-plated mating contacts and phosphor bronze material. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from manufacturers including Preci-Dip, Harwin, and TE Connectivity provide functional equivalents with improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Connector type: Header, right-angle configuration
Contact type: Male pin
Number of positions: 72 (primary criterion)
Pitch: 0.100" (2.54mm) mating pitch
Row spacing: 0.100" (2.54mm)
Mounting: Through hole, right angle
Termination: Solder
Current rating: 3A per contact minimum
Operating temperature range: Must encompass or match -65°C to 125°C
Flammability: UL94 V-0

Substitute parts are grouped into two categories: direct equivalents (72-position, identical row spacing) and functional alternatives (80-position variant). The 80-position part (4-103149-0) provides expanded connectivity but requires design accommodation. All other substitutes maintain the 72-position, 2-row configuration with identical pitch specifications.

Engineering Selection Recommendations

For applications requiring direct form-fit-function replacement with identical 72-position configuration, the Preci-Dip 802-V3-072-20-001101 and 892-series variants are primary selections. These parts maintain the 2.54mm pitch, 2-row spacing, and through-hole right-angle mounting while offering ROHS3 compliance and active product status.

The 802-V3-072-20-001101 provides gold mating contact finish matching the original specification, with operating temperature range of -55°C to 125°C. The 892-series alternatives (892-70-072-20-002101, 892-80-072-20-001101, 892-80-072-20-002101) offer tin or gold finishes with identical electrical ratings and temperature performance.

The Harwin M20-9743646 provides a cuttable header variant with ROHS3 compliance and active status, suitable for applications requiring modular connector configurations. Operating temperature is limited to -40°C to 105°C.

The TE Connectivity 4-103149-0 represents a functional alternative with 80 positions instead of 72, requiring design modification. This part maintains identical pitch and row spacing but expands connectivity capacity. Operating temperature range is -65°C to 105°C with RoHS non-compliance status.

For new designs, Preci-Dip 802-V3-072-20-001101 is recommended as the primary substitute, offering full compliance, active availability, and parameter alignment. For legacy system maintenance requiring exact thermal performance (-65°C minimum), the TE Connectivity 4-103149-0 provides the closest temperature specification despite position count variance.

Frequently Asked Questions (FAQ)

Q: Can the 80-position TE Connectivity 4-103149-0 be used as a direct replacement for the 68-position Amphenol ICC 68021-172?

A: No. The 4-103149-0 contains 80 positions versus 72 positions in the original part. While pitch and row spacing are identical, the connector footprint is larger. Design modification is required to accommodate the additional 8 positions. This part functions as an alternative only when expanded connectivity is acceptable.

Q: What is the primary difference between Preci-Dip 802-V3-072-20-001101 and 892-70-072-20-002101?

A: Both maintain 72 positions and 2.54mm pitch. The 802-V3 uses PCT/Polyester insulation material with gold mating contact finish. The 892-70 uses Polyamide (PA) insulation with gold mating contact finish. Contact length for mating differs: 802-V3 at 0.195" (4.95mm) versus 892-70 at 0.276" (7.00mm). Selection depends on mating depth requirements and insulation material compatibility.

Q: Are all substitute parts RoHS compliant?

A: No. The TE Connectivity 4-103149-0 is RoHS non-compliant, matching the original part status. All Preci-Dip (802 and 892 series) and Harwin M20-9743646 parts are ROHS3 compliant. For applications requiring RoHS compliance, select from the Preci-Dip or Harwin alternatives.

Q: What is the operating temperature limitation when substituting with Harwin M20-9743646?

A: The Harwin part operates from -40°C to 105°C, compared to the original -65°C to 125°C range. This represents a 25°C reduction at the low end and 20°C reduction at the high end. Applications requiring full -65°C to 125°C performance must use Preci-Dip 802-V3-072-20-001101 or 892-series alternatives.

Q: Do all 72-position substitutes have identical contact length specifications?

A: No. Contact length for mating varies across substitutes: original 68021-172 at 0.230" (5.84mm), Preci-Dip 802-series at 0.195" (4.95mm), Preci-Dip 892-70 at 0.276" (7.00mm), Preci-Dip 892-80 at 0.236" (6.00mm), and Harwin M20-9743646 at 0.228" (5.80mm). Verify mating depth compatibility with receiving connector before selection.

Q: Which substitute offers the closest electrical and thermal match to the original 68021-172?

A: The Preci-Dip 802-V3-072-20-001101 provides the closest alignment: identical 72-position count, 2.54mm pitch, 2-row spacing, 3A current rating, gold mating contact finish, and operating temperature of -55°C to 125°C. The only variance is the 10°C reduction at the low temperature extreme.
