Molex 0740612607 VHDM 200-Position Backplane Connector Header

Part Overview

The Molex 0740612607 is a 200-position VHDM backplane connector header designed for through-hole PCB mounting applications. This connector features male pins with shielded construction, gold-plated contacts, and is rated for 3A current at 120V. The part is currently classified as obsolete, which necessitates identification of active substitute components to maintain design continuity and ensure ongoing component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740612607 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Left)
• Position count and array configuration (200 positions; 8 rows × 25 columns)
• Pitch specification (0.079" / 2.00mm)
• Mounting and termination method (Through Hole; Press-Fit)
• Electrical ratings (3A current; 120V voltage)
• Physical features (Shielded; Gold contact finish; Black color)
• Compliance certifications (UL94 V-0; RoHS non-compliant status)

The substitute part 0740612501 meets all these criteria and is classified as an active product, providing direct functional and mechanical compatibility with the obsolete 0740612607.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740612501 is the direct active substitute for the obsolete 0740612607. Both components are manufactured by Molex within the same VHDM 74061 series and maintain identical electrical, mechanical, and compliance specifications. The substitute part is currently in active production status with confirmed inventory availability.

The only variance between the two parts is contact finish thickness: the 0740612607 specifies 50.0µin (1.27µm) while the 0740612501 specifies 30.0µin (0.76µm). Both thicknesses remain within acceptable gold plating specifications for connector applications and do not affect functional performance or reliability. The substitute part also differs in packaging format (Tube versus Bulk), which is a logistical consideration rather than a technical one.

For new designs and production applications requiring this connector type, the 0740612501 should be specified. For existing designs currently using the 0740612607, direct substitution with the 0740612501 is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 0740612501 be used as a direct replacement for the 0740612607 in existing PCB designs?

A: Yes. Both connectors share identical mechanical dimensions, pin pitch, mounting method, and electrical ratings. No PCB layout or design changes are required for substitution.

Q: What is the significance of the contact finish thickness difference?

A: The contact finish thickness variance (50.0µin versus 30.0µin) reflects manufacturing process differences between the obsolete and active production versions. Both specifications meet industry standards for gold-plated connector contacts and do not impact electrical performance, mating cycles, or reliability in this application.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical UL94 V-0 flammability ratings, RoHS non-compliant status, and REACH unaffected classification. Moisture sensitivity level and electrical ratings are equivalent.

Q: Does the packaging difference (Tube versus Bulk) affect component performance?

A: No. Packaging format is a supply chain and handling consideration only. The connector itself is identical regardless of packaging method.

Q: Is the 0740612501 available for immediate procurement?

A: Yes. The 0740612501 is classified as an active product with confirmed inventory availability in stock.
