Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 72937-002 is determined by strict equivalence across the following critical parameters:

• Connector Type: Header, Male Pins (electrical interface requirement)
• Number of Positions: 48 (physical and electrical capacity)
• Number of Positions Loaded: 32 (functional pin count)
• Pitch: 0.100" (2.54mm) (mechanical spacing standard)
• Number of Rows: 3 (physical configuration)
• Mounting Type: Through Hole, Right Angle (PCB integration method)
• Termination: Solder (assembly process compatibility)
• Contact Finish: Gold (electrical performance and reliability)

The substitute part 09231326921 (HARTING) meets all these criteria, providing direct functional equivalence for the obsolete 72937-002.

Parameter Comparison

Engineering Selection Recommendations

The HARTING 09231326921 serves as the direct functional equivalent for the obsolete Amphenol ICC 72937-002. Both components share identical electrical and mechanical specifications across all critical substitution parameters: 48-position DIN connector header configuration, 32 loaded positions, 0.100" pitch, 3-row layout, right-angle through-hole mounting, and gold-plated male pins.

The primary distinction is regulatory compliance: the 09231326921 achieves ROHS3 compliance, whereas the 72937-002 is RoHS non-compliant. For applications subject to RoHS requirements, the HARTING part is the appropriate selection. The insulation material differs (thermoplastic glass-filled versus polycarbonate), but both materials maintain equivalent moisture sensitivity ratings and environmental performance within the specified operating parameters.

The 09231326921 is currently in active production with confirmed inventory availability, ensuring supply chain continuity for replacement and new design applications.

Frequently Asked Questions (FAQ)

Q: Can the 09231326921 directly replace the 72937-002 in existing assemblies?

A: Yes. Both connectors share identical electrical and mechanical specifications across all critical parameters: 48 positions, 32 loaded, 0.100" pitch, 3 rows, right-angle through-hole mounting, and gold contact finish. Physical and electrical compatibility is confirmed.

Q: What is the significance of the RoHS compliance difference?

A: The 72937-002 is RoHS non-compliant, while the 09231326921 is ROHS3 compliant. For applications or markets requiring RoHS compliance, the 09231326921 is the mandated selection. For legacy systems without RoHS requirements, both parts function identically.

Q: Does the insulation material difference affect performance?

A: Both materials (polycarbonate and thermoplastic glass-filled) maintain equivalent moisture sensitivity ratings (MSL 1 - Unlimited) and environmental performance. The material difference does not impact electrical or mechanical compatibility for this connector category.

Q: Why is the 72937-002 listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The 09231326921 provides continued access to equivalent functionality through an active, in-stock alternative.

Q: Are there any packaging or lead time considerations?

A: The 09231326921 is supplied in bulk packaging with confirmed inventory availability (1272 pcs in stock), ensuring reliable procurement for both immediate replacement needs and production planning.
