Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0740612583 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Voltage rating (120V), current rating (3A), and contact finish composition (gold plating at 30.0µin thickness) ensure electrical compatibility and signal integrity.

Mechanical Parameters: The 200-position configuration with 8 rows and 25 columns, 0.079" (2.00mm) pitch, through-hole mounting, and press-fit termination define the physical interface and PCB compatibility.

Connector Geometry: VHDM style with guide-left orientation and shielded construction must be preserved to ensure proper mating and EMI protection.

Material and Compliance: UL94 V-0 flammability rating and MSL 1 classification establish the environmental and reliability baseline.

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

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740612501 is the direct functional equivalent of the obsolete Molex 0740612583. Both parts are manufactured by Molex within the VHDM 74061 series and share identical electrical ratings, mechanical dimensions, and material specifications.

The primary distinction is product status: the 0740612583 is classified as obsolete, while the 0740612501 maintains active product status. This status difference reflects manufacturing lifecycle positioning rather than technical capability. The substitute part carries identical UL94 V-0 flammability certification and MSL 1 moisture sensitivity classification, ensuring equivalent reliability and environmental performance.

Both parts maintain RoHS non-compliant status, indicating they contain materials not restricted under RoHS directives. This classification is consistent across the product line and does not affect substitution eligibility.

The 0740612501 is supplied in tube packaging, providing standard handling and storage conditions suitable for production environments.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0740612501 be used as a direct replacement for the 0740612583 in existing designs?

A: Yes. The 0740612501 is electrically and mechanically identical to the 0740612583. All electrical parameters (120V voltage rating, 3A current rating, gold contact finish), mechanical specifications (200 positions, 8×25 configuration, 2.00mm pitch, through-hole mounting), and material certifications (UL94 V-0, MSL 1) are identical. The substitute part can be used without design modification.

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

A: The primary difference is product lifecycle status. The 0740612583 is obsolete, while the 0740612501 is active. Both parts are manufactured by Molex to the same VHDM 74061 series specifications. The 0740612501 offers improved supply chain availability due to its active status.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical certifications: UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. Both are RoHS non-compliant, which is consistent with the product series.

Q: Does packaging differ between these parts?

A: The 0740612583 packaging is not specified in available documentation. The 0740612501 is supplied in tube packaging, which is standard for this connector type and suitable for production assembly processes.

Q: Are the contact finish specifications identical?

A: Yes. Both parts feature gold-plated contacts with a finish thickness of 30.0µin (0.76µm), ensuring equivalent electrical performance and corrosion resistance.

Q: Can I use the 0740612501 in new designs?

A: Yes. The 0740612501 is the active equivalent and is suitable for new design implementations. Its active product status ensures ongoing availability and manufacturing support.
