Engineering Selection Recommendations
The Molex 0740601001 is the direct substitute for the obsolete 0740601006. Both parts are manufactured by Molex within the VHDM 74060 series and maintain identical electrical and mechanical specifications for connector configuration, current handling, voltage rating, and operating temperature range.
The primary distinction is product status: the 0740601006 is obsolete, while the 0740601001 is active production. The 0740601001 additionally provides ROHS3 compliance, whereas the original part is RoHS non-compliant. For new designs or ongoing production requiring regulatory compliance, the 0740601001 is the appropriate selection.
Contact finish thickness differs between the two parts (50.0µin versus 30.0µin), but both maintain gold plating and are functionally equivalent for the specified electrical and mechanical requirements of this connector category.
Frequently Asked Questions (FAQ)
Q: Are the 0740601006 and 0740601001 mechanically interchangeable?
A: Yes. Both parts share identical connector style (VHDM), position count (80), row/column arrangement (8×10), pitch (0.079"), mounting type (through hole), and termination method (press-fit). PCB footprints and mating interfaces are identical.
Q: What is the difference in contact finish thickness, and does it affect performance?
A: The 0740601006 has 50.0µin (1.27µm) gold plating, while the 0740601001 has 30.0µin (0.76µm). Both thicknesses provide adequate contact durability and conductivity for the 3A current rating and 120V voltage specification. The difference does not impact electrical performance or reliability for this connector application.
Q: Why is RoHS compliance different between these parts?
A: The 0740601006 predates RoHS3 requirements and is non-compliant. The 0740601001 is manufactured to current ROHS3 standards. For applications subject to regulatory compliance requirements, the 0740601001 is the appropriate choice.
Q: Can I use the 0740601001 as a direct replacement in existing designs?
A: Yes. The 0740601001 is electrically and mechanically equivalent to the 0740601006 across all critical parameters: connector type, position count, pitch, current rating, voltage rating, operating temperature range, and flammability rating. No design modifications are required.
Q: What packaging is available for the substitute part?
A: The 0740601001 is supplied in tube packaging, whereas the original part packaging is not specified in the available data.
