Amphenol ICC 68022-172 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68022-172 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 and design continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 68022-172 are evaluated based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - Mating (0.100" / 2.54mm)
• Row spacing - Mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Contact shape (Square)
• Fastening type (Push-Pull)
• Material flammability rating (UL94 V-0)

Secondary Compatibility Factors:

• Number of positions (72 or compatible breakaway configurations)
• Number of rows (2)
• Insulation height (within tolerance range)
• Contact length - Mating (0.318" / 8.08mm)
• Contact length - Post (0.110" / 2.79mm)

The identified substitute parts maintain these core parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

3M 2372-5221-TG provides the closest functional match to the 68022-172, maintaining identical position count (72), row configuration (2), and all critical mechanical parameters. This part is currently active in production, ensuring long-term availability. The primary design consideration is the reduced current rating (3A versus 5A), which requires circuit-level verification if the original design operates above 3A per contact. Operating temperature range (-55°C to 105°C) is specified and suitable for standard industrial applications.

TE Connectivity 4-102979-0 offers an alternative with breakaway capability and an extended position count (80 positions). This configuration accommodates future expansion or allows selective position utilization through breakaway sections. The operating temperature range extends to -65°C, providing enhanced low-temperature performance. The 80-position format requires PCB layout modification to accommodate the additional positions, though unused positions can be removed via breakaway sections. Current rating (3A) matches the 3M alternative.

Both substitute parts maintain UL94 V-0 flammability compliance, identical pitch and row spacing, and equivalent mechanical mounting characteristics. Selection between these alternatives depends on application current requirements, operating temperature range, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the 3M 2372-5221-TG or TE Connectivity 4-102979-0 directly replace the Amphenol ICC 68022-172 without PCB modification?

A: The 3M 2372-5221-TG maintains identical position count and footprint, enabling direct PCB substitution. The TE Connectivity 4-102979-0 has 80 positions versus 72, requiring PCB layout modification unless the additional positions are removed via breakaway sections.

Q: What is the impact of the reduced current rating (3A) in the substitute parts compared to the original 5A specification?

A: The substitute parts are rated for 3A per contact. Applications requiring sustained current above 3A per contact must be re-evaluated. If the original design operates within 3A per contact, substitution is permissible from a current capacity standpoint.

Q: Are the substitute parts compatible with existing mating connectors designed for the 68022-172?

A: Yes. Both substitute parts maintain the 0.100" (2.54mm) pitch, row spacing, contact geometry, and push-pull fastening mechanism, ensuring compatibility with existing mating connectors.

Q: What are the differences in contact material between the original and substitute parts?

A: The 68022-172 uses Phosphor Bronze contacts, while both substitutes use Copper Alloy. Both materials provide equivalent electrical conductivity and mechanical durability for standard applications. Contact finish (gold plating) is consistent across all three parts.

Q: Do the substitute parts meet the same compliance standards as the original?

A: All three parts share UL94 V-0 flammability rating, MSL 1 (Unlimited) moisture sensitivity, and identical HTSUS classification. RoHS non-compliance status is consistent across all parts. Operating temperature specifications are provided for the substitute parts but not for the original.

Q: Can the TE Connectivity 4-102979-0 be used in applications requiring exactly 72 positions?

A: Yes. The 80-position configuration includes breakaway sections that allow removal of unused positions to achieve a 72-position footprint matching the original design.
