Amphenol ICC 67997-372H Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 67997-372H is a vertical through-hole rectangular connector header with 72 positions at 2.54mm pitch, designed for board-to-board applications. This connector belongs to the BERGSTIK® II series and features male pins with gold-plated mating contacts and phosphor bronze material. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the 67997-372H is determined by strict alignment with the following critical parameters:

Connector configuration: Header type with male pins
Contact count and arrangement: 72 positions in 2 rows
Pitch specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting method: Through-hole solder termination
Electrical rating: 3A current capacity
Environmental compliance: UL94 V-0 flammability rating
Temperature range: Operating capability within or exceeding -65°C to 130°C

Two active alternatives meet these core substitution criteria: the 3M 2372-6121-TG and the Preci-Dip 450-V3-272-00-006101. Both maintain identical position count, pitch, mounting type, and current rating. Variations in contact geometry, material composition, and contact finish thickness represent acceptable engineering trade-offs within the rectangular connector category.

Engineering Selection Recommendations

3M 2372-6121-TG is the primary substitute for the Amphenol ICC 67997-372H. Both parts share identical mating contact length, post length, and overall contact length specifications. The 3M part maintains active product status and equivalent electrical performance. The operating temperature range of -55°C to 105°C is narrower than the original part; applications requiring operation below -55°C or above 105°C require thermal analysis. Both parts carry RoHS non-compliant and REACH Affected designations.

Preci-Dip 450-V3-272-00-006101 serves as a secondary substitute with distinct advantages in regulatory compliance. This part is ROHS3 Compliant and REACH Unaffected, making it suitable for applications with enhanced environmental requirements. The contact geometry differs with circular pins instead of square, and shorter overall contact length (0.394" versus 0.450"). The operating temperature range extends to 125°C, exceeding the 3M alternative. The Preci-Dip part includes a 150VDC voltage rating specification absent from the original part documentation.

Selection between the two substitutes depends on regulatory compliance requirements and thermal operating envelope. For legacy system compatibility requiring minimal design modification, the 3M 2372-6121-TG provides the closest electrical and mechanical alignment. For new designs or applications requiring RoHS3 compliance, the Preci-Dip 450-V3-272-00-006101 is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can the 3M 2372-6121-TG directly replace the Amphenol ICC 67997-372H without PCB modification?

A: The 3M part maintains identical pitch, row spacing, contact length, and insulation height specifications. Direct PCB footprint compatibility is confirmed. Contact geometry differs (square versus square in both cases), and contact material composition varies, but these do not affect mechanical interchangeability for standard through-hole solder applications.

Q: What are the thermal operating limitations when substituting with the 3M 2372-6121-TG?

A: The 3M part operates from -55°C to 105°C, compared to the original -65°C to 130°C range. Applications requiring operation below -55°C or above 105°C must employ the Preci-Dip 450-V3-272-00-006101 or conduct thermal analysis to confirm the 3M part remains within acceptable performance margins.

Q: Does the Preci-Dip 450-V3-272-00-006101 require PCB redesign?

A: The Preci-Dip part exhibits shorter overall contact length (0.394" versus 0.450") and increased insulation height (0.110" versus 0.100"). These dimensional differences may require PCB footprint adjustment, particularly for applications with tight vertical clearance constraints or specific mating depth requirements. Contact geometry is circular rather than square, affecting insertion force characteristics.

Q: Which substitute part is suitable for RoHS3-compliant applications?

A: The Preci-Dip 450-V3-272-00-006101 is ROHS3 Compliant and REACH Unaffected. The 3M 2372-6121-TG and original Amphenol ICC part are both RoHS non-compliant. For applications requiring RoHS3 certification, the Preci-Dip part is the mandatory selection.

Q: Are contact finish specifications compatible between the original and substitute parts?

A: All three parts feature gold-plated mating contacts. The original Amphenol ICC part specifies 50.0µin (1.27µm) gold thickness; the 3M part specifies 10.0µin (0.25µm); the Preci-Dip part specifies 29.5µin (0.75µm). These variations fall within acceptable ranges for standard connector applications. Post-side finishes differ: the original uses unspecified finish, the 3M uses Tin-Lead, and the Preci-Dip uses Tin.

Q: What is the inventory status for substitute parts?

A: The 3M 2372-6121-TG has 1023 pieces in stock. The Preci-Dip 450-V3-272-00-006101 has 988 pieces in stock. Both parts are actively manufactured and available for immediate procurement.
