Substitute Part Grouping Explanation

The Molex 0740611004 qualifies as a direct substitute for the 0740611012 based on strict parameter equivalence. Both parts share identical electrical and mechanical specifications:

• Connector configuration: 80-position VHDM header, male pins, guide left
• Physical dimensions: 8 rows × 10 columns, 0.079" (2.00mm) pitch
• Electrical ratings: 3A current, 120V voltage
• Contact system: Gold-plated press-fit termination
• Mechanical mounting: Through-hole PCB assembly
• Shielding and flammability: Shielded design, UL94 V-0 rated

The substitution is valid because all allowed parameters for backplane connector selection—pitch, position count, contact finish, current/voltage ratings, and mounting type—are identical between the two parts.
