Substitute Part Grouping Explanation

Substitution for the Molex 0740619032 is determined by strict equivalence across the following critical parameters:

• Connector Series and Style: VHDM 74061 series with Guide Left orientation
• Electrical Configuration: 80-position header with 8 rows × 10 columns arrangement
• Contact Pitch: 0.079" (2.00mm) spacing
• Electrical Ratings: 3A current capacity and 120V voltage rating
• Physical Interface: Through-hole mounting with press-fit termination
• Contact Properties: Gold plating at 30.0µin thickness
• Compliance: UL94 V-0 flammability, ROHS3, and REACH Unaffected status

The substitute part must maintain identical mechanical and electrical characteristics to ensure direct compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct equivalent substitute for the obsolete 0740619032. Both parts are identical in all electrical and mechanical specifications, including connector configuration, contact ratings, and compliance certifications. The primary distinction is product status: the 0740611004 is currently active in production, whereas the 0740619032 is obsolete.

For new designs or component replenishment, the 0740611004 should be selected. This part maintains full compatibility with existing PCB layouts and mating connectors designed for the 0740619032. The active production status of the 0740611004 ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)
