Key Parameters

Substitute Part Grouping Explanation

The Molex 0761651807 qualifies as a direct substitute based on the following critical parameters:

Electrical Compatibility:

• Identical 72-position configuration with 24 differential pairs
• Matching 0.053" (1.35mm) pitch spacing
• Same 30V voltage rating and -55°C to 85°C operating temperature range
• Identical contact finish specification (gold, 30.0µin)

Mechanical Compatibility:

• Same 9×8 matrix layout
• Identical through-hole mounting and press-fit termination
• Matching connector style (Impact series header with male pins)
• Same color specification (black)

Regulatory & Compliance Alignment:

• ROHS3 compliant (matching the main part)
• UL94 V-0 flammability rating
• MSL 1 rating (unlimited moisture sensitivity level)
• Identical ECCN and HTSUS classifications

The substitution is based strictly on parameter equivalence. The 0761651807 differs only in product status (active vs. obsolete) and packaging format (tray vs. bulk), neither of which affects functional or mechanical compatibility.
