Molex 0740612544 VHDM 200-Position Backplane Connector Header

Part Overview

The Molex 0740612544 is a 200-position VHDM backplane connector header designed for through-hole PCB mounting applications. This component features male pins with shielding, gold-plated contacts, and a guide-left configuration. The part is classified as obsolete, making identification of active equivalent components essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740612544 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: 200 positions arranged in 8 rows × 25 columns
• Pitch Specification: 0.079" (2.00mm) contact spacing
• Mounting and Termination: Through-hole PCB mounting with press-fit termination
• Electrical Ratings: 3A current rating and 120V voltage rating
• Contact Properties: Gold plating at 30.0µin (0.76µm) thickness
• Physical Characteristics: Black color, shielded design, UL94 V-0 flammability rating

The substitute part Molex 0740612501 meets all these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740612501 is the direct functional equivalent of the obsolete Molex 0740612544. Both components share identical electrical specifications, mechanical dimensions, contact properties, and flammability certifications. The primary distinction is product status: the 0740612544 is obsolete, while the 0740612501 maintains active status with confirmed inventory availability.

For new designs or ongoing procurement requirements, the 0740612501 is the appropriate selection. Both parts comply with identical regulatory classifications (RoHS non-compliant, ECCN EAR99, HTSUS 8536.69.4040) and carry the same moisture sensitivity level. The substitute part is supplied in tube packaging, which may differ from the original part's unspecified packaging format but does not affect functional compatibility.
