Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0740612533 is determined by strict equivalence across the following critical parameters:

• Connector type and style: Header, Male Pins with VHDM, Guide Left configuration
• Position count and array geometry: 200 positions arranged in 8 rows × 25 columns
• Pitch specification: 0.079" (2.00mm)
• Mounting and termination: Through-hole PCB mounting with press-fit termination
• Electrical ratings: 3A current rating and 120V voltage rating
• Contact specifications: Gold plating at 30.0µin (0.76µm) thickness
• Physical characteristics: Black color with shielded construction
• Compliance: UL94 V-0 flammability rating

The substitute part Molex 0740612501 maintains identical electrical, mechanical, and dimensional specifications across all these parameters. The primary distinction is product status: the 0740612501 is active production, whereas the 0740612533 is obsolete.
