Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68021-372 is determined by the following critical parameters:

• Number of Positions and Rows: Must match 72 positions in 2 rows
• Pitch - Mating: Must be 0.100" (2.54mm)
• Row Spacing - Mating: Must be 0.100" (2.54mm)
• Mounting Type: Must be through-hole, right-angle
• Contact Type: Must be male pin
• Termination: Must be solder
• Fastening Type: Must be push-pull
• Current Rating: Must support minimum 3A per contact
• Voltage Rating: Must support minimum 110V
• Operating Temperature Range: Must encompass -65°C to 125°C or be compatible with application requirements
• Connector Style: Board-to-board configuration

The substitute parts listed below meet these core electrical and mechanical parameters. Variations in contact material, contact finish, insulation material, and compliance status are noted but do not preclude substitution when the above parameters align.

Engineering Selection Recommendations

Primary Substitute: Preci-Dip 802-V3-072-20-001101

The Preci-Dip 802-V3-072-20-001101 is the closest functional equivalent to the 68021-372. It matches all critical mechanical parameters: 72 positions, 2 rows, 0.100" pitch, through-hole right-angle mounting, male pin contacts, solder termination, and push-pull fastening. The connector supports 3A per contact and 150VDC, exceeding the original 110V specification. The primary difference is the circular contact shape versus the original square contacts, and the use of brass with gold finish instead of phosphor bronze. This part is active in production and ROHS3 compliant, making it suitable for new designs and ongoing production support.

Secondary Substitute: Harwin Inc. M20-9743646

The Harwin M20-9743646 maintains identical position count, pitch, row spacing, and mounting configuration. It features square contacts matching the original design, solder termination, and push-pull fastening. The connector is rated for 3A per contact and is ROHS3 compliant. The operating temperature range is -40°C to 105°C, which is narrower than the original -65°C to 125°C specification. This part is suitable for applications within the reduced temperature range and is actively produced.

Tertiary Substitute: TE Connectivity 9-146308-0

The TE Connectivity 9-146308-0 differs in position count (80 positions versus 72) and is classified as a breakaway connector with board-to-board or cable style capability. While it maintains the 0.100" pitch, 2-row configuration, through-hole right-angle mounting, and 3A current rating, the increased position count makes it suitable only for applications where the additional 8 positions can be accommodated or left unused. This part is active and ROHS3 compliant.

Compliance Considerations

All substitute parts are ROHS3 compliant, whereas the original 68021-372 is RoHS non-compliant. For applications requiring RoHS compliance, any of the three substitutes is acceptable. The original part's REACH Affected status contrasts with the Preci-Dip part (REACH Unaffected) and Harwin part (REACH Unaffected), providing regulatory advantages in substitute selection.

Frequently Asked Questions (FAQ)

Q: Can the Preci-Dip 802-V3-072-20-001101 directly replace the Amphenol ICC 68021-372?

A: Yes, the Preci-Dip part is a direct functional replacement. Both connectors have 72 positions in 2 rows with 0.100" pitch and row spacing, through-hole right-angle mounting, male pin contacts, solder termination, and push-pull fastening. The primary difference is contact geometry (circular versus square) and material composition, which do not affect electrical or mechanical compatibility in standard board-to-board applications.

Q: What is the significance of the contact shape difference between the original and substitute parts?

A: Contact shape (square versus circular) affects mating force and contact pressure distribution. Square contacts, as in the original 68021-372 and Harwin M20-9743646, provide edge-to-edge contact geometry. Circular contacts, as in the Preci-Dip 802-V3-072-20-001101, provide point-to-surface contact. Both geometries are standard in 0.100" pitch connectors and are compatible with standard mating receptacles designed for this pitch.

Q: Why does the TE Connectivity 9-146308-0 have 80 positions instead of 72?

A: The TE Connectivity part is from the AMPMODU Mod II series and is offered in multiple position configurations. The 80-position variant can be used in applications where additional positions are available on the PCB, or positions can be left unmated. For strict 72-position requirements, the Preci-Dip or Harwin alternatives are preferred.

Q: Are there temperature range limitations when substituting parts?

A: The original 68021-372 operates from -65°C to 125°C. The Preci-Dip 802-V3-072-20-001101 matches this range (-55°C to 125°C is slightly narrower at the low end). The Harwin M20-9743646 has a reduced range of -40°C to 105°C, and the TE Connectivity 9-146308-0 operates from -65°C to 105°C. Verify that the selected substitute meets the application's temperature requirements.

Q: What is the packaging difference between these parts?

A: The Amphenol ICC 68021-372 and Preci-Dip 802-V3-072-20-001101 are supplied in bulk packaging. The Harwin M20-9743646 is also bulk packaged. The TE Connectivity 9-146308-0 is supplied in tray packaging. Bulk packaging is suitable for high-volume assembly, while tray packaging provides organized component presentation. Confirm packaging compatibility with your assembly process.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original 68021-372 is RoHS non-compliant. All three substitute parts—Preci-Dip 802-V3-072-20-001101, Harwin M20-9743646, and TE Connectivity 9-146308-0—are ROHS3 compliant, making them suitable for applications requiring RoHS compliance.

Q: What is the current rating for each connector?

A: All connectors, including the original and substitutes, are rated for 3A per contact. This rating is consistent across the Amphenol ICC 68021-372, Preci-Dip 802-V3-072-20-001101, Harwin M20-9743646, and TE Connectivity 9-146308-0.
