Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740591004 is determined by strict equivalence across the following critical parameters:

Connector configuration: 60-position header with 6 rows and 10 columns Pitch specification: 0.079" (2.00mm) center-to-center spacing Connector style: VHDM with guide right orientation Mounting method: Through-hole press-fit termination Electrical ratings: 2A current capacity and 120V voltage rating Contact system: Gold-plated male pins with 30.0µin finish thickness Mechanical features: Shielded design with black housing Environmental compliance: UL94 V-0 flammability rating and MSL 1 rating

The substitute part must maintain identical mechanical and electrical characteristics to ensure direct compatibility with existing PCB layouts and mating connectors.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740591001 is the direct substitute for the obsolete 0740591004. Both components are manufactured by Molex within the VHDM 74059 series and maintain identical mechanical, electrical, and environmental specifications across all critical parameters including connector configuration, pitch, current and voltage ratings, temperature range, and flammability certification.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 0740591004 is classified as obsolete and does not meet current RoHS3 requirements, while the 0740591001 is in active production and is ROHS3 compliant. For new designs or system refreshes, the 0740591001 is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part maintains functional equivalence.

Packaging differs between the two parts, with the 0740591001 supplied in tube format. This distinction affects handling and storage procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0740591001 be used as a direct replacement for the 0740591004 in existing assemblies?

A: Yes. The 0740591001 is mechanically and electrically identical to the 0740591004 across all specified parameters. Both components feature the same 60-position VHDM connector configuration, 2.00mm pitch, 2A current rating, 120V voltage rating, and operating temperature range. PCB layouts and mating connectors designed for the 0740591004 will accommodate the 0740591001 without modification.

Q: What is the difference between these two part numbers?

A: The 0740591004 is obsolete and RoHS non-compliant, while the 0740591001 is in active production and ROHS3 compliant. All mechanical and electrical specifications are identical. The 0740591001 is supplied in tube packaging rather than unspecified packaging for the 0740591004.

Q: Are there any compatibility concerns when substituting the 0740591001 for the 0740591004?

A: No compatibility concerns exist. The connector style, pin configuration, pitch, mounting method, and electrical ratings are identical. The substitute part will function identically in the same application.

Q: Does the packaging difference between these parts affect performance?

A: No. Packaging format affects handling, storage, and logistics but does not impact electrical or mechanical performance. Both parts meet identical environmental and flammability specifications.

Q: Is the 0740591001 suitable for applications requiring RoHS compliance?

A: Yes. The 0740591001 is ROHS3 compliant, making it suitable for applications and markets with RoHS requirements. The 0740591004 does not meet RoHS standards.
