Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740611034 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Left)
• Position count and matrix configuration (80 positions; 8×10 rows/columns)
• Pitch specification (0.079" / 2.00mm)
• Mounting and termination method (Through Hole; Press-Fit)
• Electrical ratings (3A current; 120V voltage)
• Physical characteristics (Shielded; Gold contact finish; Black color)
• Compliance standards (UL94 V-0 flammability rating)

The Molex 0740611004 qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction between these parts is product status and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct functional equivalent of the 0740611034 for all electrical, mechanical, and dimensional applications. Selection between these parts should be based on the following criteria:

Product Status: The 0740611034 is obsolete and no longer actively manufactured or supported. The 0740611004 maintains active product status with ongoing availability.

Regulatory Compliance: The 0740611004 is ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance directives. The 0740611034 is RoHS non-compliant, which may restrict use in applications subject to EU or equivalent regulatory frameworks.

Procurement and Supply Chain: The 0740611004 is available in higher inventory quantities (1488 pcs) compared to the 0740611034 (865 pcs), with standardized tube packaging for the substitute part.

For new designs, design revisions, or applications requiring regulatory compliance documentation, the 0740611004 is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part satisfies the functional requirements.

Frequently Asked Questions (FAQ)

Q: Are the 0740611034 and 0740611004 mechanically interchangeable?

A: Yes. Both parts share identical connector style (VHDM, Guide Left), position count (80), matrix configuration (8×10), pitch (2.00mm), and mounting method (through-hole press-fit). Physical dimensions and PCB footprints are equivalent.

Q: Can the 0740611004 replace the 0740611034 in existing assemblies?

A: Yes, provided the application does not have specific constraints tied to the obsolete part number. The electrical ratings (3A, 120V), contact finish (gold), and shielding characteristics are identical.

Q: What is the primary reason to transition from 0740611034 to 0740611004?

A: The 0740611034 is obsolete and subject to end-of-life discontinuation. The 0740611004 is an active product with ongoing manufacturer support, ensuring long-term availability and supply chain stability.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS3 compliance on the 0740611004 reflects material composition and manufacturing process standards, not electrical or mechanical performance. Both parts meet identical electrical specifications.

Q: Are there packaging considerations when sourcing the 0740611004?

A: The 0740611004 is supplied in tube packaging. Verify that tube packaging is compatible with your assembly and handling processes. The 0740611034 packaging specification was not provided.

Q: Can both parts be used interchangeably in the same production run?

A: From a functional standpoint, yes. However, design documentation and bill of materials should specify a single part number to maintain traceability and supply chain consistency.
