Amphenol ICC 67997-372 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 67997-372 is a rectangular connector header featuring 72 positions at 2.54mm pitch, designed for through-hole board-to-board applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Substitute Part Grouping Explanation

Substitute parts for the 67997-372 are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

72-position count with 2-row configuration
0.100" (2.54mm) mating pitch and row spacing
Through-hole solder termination
3A current rating capability
UL94 V-0 flammability compliance
Male pin contact type

The 4-103240-0 (TE Connectivity) deviates from the primary group due to an 80-position count and 0.090" insulation height, representing a partial compatibility scenario requiring design verification. The 450-V3-272-00-006101 (Preci-Dip) and DW-36-07-L-D-200 (Samtec) maintain full parameter alignment with the main part across all critical dimensions and electrical specifications.

Engineering Selection Recommendations

Primary Substitutes (Full Compatibility):

The 2372-6121-TG (3M 2300 Series) and 450-V3-272-00-006101 (Preci-Dip 450 Series) provide direct functional equivalence to the 67997-372. Both maintain 72-position, 2-row configuration with 0.100" pitch and through-hole solder termination. The 3M part is currently active in production with established supply chains. The Preci-Dip part offers ROHS3 compliance and extended operating temperature range to 125°C, providing enhanced environmental performance for new designs.

Secondary Substitute (Partial Compatibility):

The 4-103240-0 (TE Connectivity AMPMODU Mod II) contains 80 positions versus 72, with a reduced insulation height of 0.090" compared to 0.100". This part functions as a substitute only when the additional 8 positions and dimensional variance are accommodated in the receiving connector design.

Recommended for New Designs:

The DW-36-07-L-D-200 (Samtec Flex Stack) is recommended for new product development due to active product status, ROHS3 compliance, and REACH unaffected designation. This part maintains full mechanical and electrical compatibility while offering superior regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 4-103240-0 be used as a direct replacement for the 67997-372?

A: The 4-103240-0 differs in position count (80 vs. 72) and insulation height (0.090" vs. 0.100"). Direct substitution requires design verification to confirm the receiving connector accommodates these dimensional changes.

Q: What is the primary difference between the 2372-6121-TG and 450-V3-272-00-006101?

A: Both maintain 72-position compatibility. The 2372-6121-TG operates to 105°C maximum, while the 450-V3-272-00-006101 extends to 125°C. The Preci-Dip part achieves ROHS3 compliance; the 3M part remains RoHS non-compliant.

Q: Are all substitute parts available in the same packaging format?

A: The 67997-372 packaging is unspecified. The 2372-6121-TG and 450-V3-272-00-006101 are available in bulk packaging. The 4-103240-0 is packaged in bulk. The DW-36-07-L-D-200 packaging is unspecified. Confirm packaging requirements with supplier specifications.

Q: Which substitute part is recommended for RoHS-compliant applications?

A: The 450-V3-272-00-006101 (Preci-Dip) and DW-36-07-L-D-200 (Samtec) both achieve ROHS3 compliance. The 2372-6121-TG and 4-103240-0 remain RoHS non-compliant.

Q: What is the current availability status of these substitute parts?

A: The 2372-6121-TG, 450-V3-272-00-006101, and DW-36-07-L-D-200 are classified as active products. The 4-103240-0 is obsolete. Inventory levels are provided in the source data; confirm current availability with authorized distributors.
