Substitute Part Grouping Explanation

Substitution for the Molex 0740611024 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Left)
• Position count and arrangement (80 positions, 8 rows × 10 columns)
• Pitch specification (0.079" / 2.00mm)
• Mounting method (Through Hole)
• Termination type (Press-Fit)
• Electrical ratings (3A current, 120V voltage)
• Physical features (Shielded, Gold contact finish)
• Material compliance (UL94 V-0)

The substitute part 0740611004 maintains full electrical and mechanical compatibility with the original part while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct substitute for the obsolete 0740611024. Both parts are electrically and mechanically identical across all functional parameters. The primary advantages of selecting 0740611004 are:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance meets current regulatory requirements, whereas the original part is RoHS non-compliant
• Tube packaging provides improved handling and storage characteristics
• Equivalent inventory availability (1488 pcs vs. 1082 pcs)

For new designs or component replacement in systems requiring RoHS compliance, 0740611004 is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part provides identical electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Are the 0740611024 and 0740611004 fully interchangeable?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting method, electrical ratings, and physical dimensions. They are direct one-to-one substitutes with no design modifications required.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (standard vs. tube). Electrical and mechanical specifications are identical.

Q: Can I use 0740611004 in place of 0740611024 in existing assemblies?

A: Yes. The substitute part maintains full compatibility with PCB layouts, mating connectors, and electrical requirements. No PCB redesign or assembly process changes are necessary.

Q: Why is RoHS compliance important for this substitution?

A: ROHS3 compliance ensures the part meets current environmental and regulatory standards for lead-free manufacturing. This is relevant for systems subject to EU regulations or customer requirements mandating RoHS compliance.

Q: Does packaging affect the technical performance of the connector?

A: No. Tube packaging is a handling and storage format only. It does not affect the electrical or mechanical performance of the connector itself.

Q: Are there any other Molex VHDM 74061 series alternatives with different position counts?

A: This reference covers only the 80-position configuration. Other position counts within the VHDM 74061 series are separate part families and are not substitutes for this application.
