Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740611104 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 characteristics (Shielded, Gold contact finish, Black color)
• Compliance standards (UL94 V-0 flammability rating)

The substitute part identified maintains full electrical and mechanical compatibility with the original specification. Substitution is valid only when all parameters match exactly.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct functional equivalent of the obsolete 0740611104. Both parts are manufactured by Molex within the same VHDM 74061 series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between the two parts is product lifecycle status and regulatory compliance. The 0740611004 is currently in active production status, whereas the 0740611104 is obsolete. Additionally, the 0740611004 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements, while the original part is RoHS non-compliant.

For new designs or component replenishment, the 0740611004 is the appropriate selection. The part is available in tube packaging and maintains full backward compatibility with applications originally designed for the 0740611104.

Frequently Asked Questions (FAQ)

Q: Are the 0740611104 and 0740611004 mechanically interchangeable?

A: Yes. Both parts share identical connector geometry, pitch (2.00mm), position count (80), mounting method (through-hole), and physical dimensions. They are direct mechanical equivalents.

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

A: The primary differences are product status and compliance. The 0740611004 is an active production part with ROHS3 compliance, while the 0740611104 is obsolete and RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 0740611004 as a replacement in existing assemblies?

A: Yes. The 0740611004 provides full functional and physical compatibility with the 0740611104 and can be used as a direct replacement in existing PCB designs and assemblies.

Q: What packaging is available for the substitute part?

A: The 0740611004 is supplied in tube packaging, which is standard for this connector type.

Q: Are there any compliance advantages to using the 0740611004?

A: Yes. The 0740611004 is ROHS3 compliant, meeting current environmental regulations. The original 0740611104 is RoHS non-compliant. For applications subject to environmental or regulatory requirements, the 0740611004 is the appropriate choice.

Q: What are the electrical specifications for both parts?

A: Both parts are rated for 3A current at 120V with gold-plated contacts (30.0µin thickness) and UL94 V-0 flammability rating. Electrical performance is identical.
