Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0740611111 is determined by strict equivalence across the following critical parameters:

• Connector type and style: Header, Male Pins; VHDM configuration with Guide Left orientation
• Electrical specifications: 80-position layout, 0.079" (2.00mm) pitch, 8 rows × 10 columns
• Mechanical interface: Through-hole mounting with press-fit termination
• Electrical performance: 3A current rating, 120V voltage rating
• Physical characteristics: Black color, shielded design, gold contact finish
• Compliance: UL94 V-0 flammability rating, MSL 1

The substitute part must maintain identical mechanical and electrical parameters to ensure direct PCB compatibility without design modification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct functional equivalent of the obsolete 0740611111. Both parts are identical in mechanical interface, electrical performance, and physical configuration. The primary distinction is product lifecycle status: the 0740611111 is obsolete, while the 0740611004 is active production.

The 0740611004 provides additional compliance advantages, meeting ROHS3 requirements compared to the non-compliant status of the original part. This substitution is suitable for new designs and ongoing production requiring current-generation component qualification.

Frequently Asked Questions (FAQ)

Q: Are the 0740611111 and 0740611004 mechanically interchangeable?

A: Yes. Both parts share identical connector geometry, pitch, position count, mounting type, and termination method. Direct PCB substitution requires no design modification.

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

A: The primary differences are product status (obsolete versus active) and RoHS compliance (non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Does packaging differ between these parts?

A: Yes. The 0740611111 is supplied in bulk packaging, while the 0740611004 is supplied in tube packaging. This does not affect component functionality or PCB compatibility.

Q: Can the 0740611004 be used in existing designs originally specified for the 0740611111?

A: Yes. The 0740611004 is a direct substitute with identical electrical and mechanical parameters. No circuit design changes are required.

Q: Are there any compliance considerations when switching to the 0740611004?

A: The 0740611004 meets ROHS3 compliance, which may be beneficial for designs subject to environmental regulations. The original 0740611111 is RoHS non-compliant.
