Substitute Part Grouping Explanation

Substitution eligibility for the 68438-572 is determined by strict alignment with the following core parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Arrangement: 72 positions in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole solder termination
Style Classification: Board-to-board connectivity
Shrouding & Contact Geometry: Unshrouded configuration
Flammability Compliance: UL94 V-0 rating

Two active substitute parts meet these core substitution criteria:

3M 2372-6121-TG (3M 2300 Series) - Active product status with extended operating temperature range
Preci-Dip 450-V3-272-00-006101 (450 Series) - Active product status with RoHS3 compliance and voltage rating specification

Engineering Selection Recommendations

3M 2372-6121-TG is suitable for applications requiring active product status with extended operating temperature capability (-55°C to 105°C). This part maintains compatibility with the original 68438-572 footprint and electrical characteristics while offering improved availability through active manufacturing status.

Preci-Dip 450-V3-272-00-006101 is recommended for applications requiring RoHS3 compliance and specified voltage rating (150VDC). This part provides the highest operating temperature range (-55°C to 125°C) and explicit electrical ratings. The circular contact geometry differs from the original square contact design but maintains functional compatibility within the 72-position, 2.54mm pitch specification.

Both substitute parts maintain UL94 V-0 flammability compliance and through-hole solder termination consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 3M 2372-6121-TG directly replace the Amphenol ICC 68438-572?

A: Yes. Both parts share identical pitch (0.100"/2.54mm), position count (72), row configuration (2 rows), mounting type (through-hole), and termination method (solder). The 3M part is mechanically and electrically compatible for board-to-board applications.

Q: What is the primary difference between the two substitute options?

A: The Preci-Dip 450-V3-272-00-006101 offers RoHS3 compliance and specified electrical ratings (150VDC, 3A), making it suitable for regulated environments. The 3M 2372-6121-TG provides broader style compatibility (board-to-board or cable) and active manufacturing status with extended temperature range.

Q: Does the circular contact shape of the Preci-Dip part affect compatibility?

A: Contact shape (circular vs. square) does not affect functional compatibility when mating pitch, position count, and row spacing remain identical. Both geometries accommodate standard 0.100" (2.54mm) pitch receptacles.

Q: Are there packaging considerations for these substitutes?

A: The Preci-Dip 450-V3-272-00-006101 is supplied in bulk packaging. The 3M 2372-6121-TG packaging specification is not provided. Verify packaging requirements with component suppliers for production planning.

Q: Which substitute is recommended for new designs?

A: Selection depends on regulatory requirements. For RoHS3-regulated applications, use Preci-Dip 450-V3-272-00-006101. For general applications prioritizing temperature range and availability, use 3M 2372-6121-TG. Both parts are active products with established supply chains.
