Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740611081 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Left)
• Position count and array configuration (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 meets all these criteria and is classified as an active product with improved compliance status, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct substitute for the obsolete 0740611081. Both parts are functionally identical across all electrical and mechanical parameters. The primary distinction is product status and regulatory compliance:

The 0740611004 is an active product with ROHS3 compliance and REACH unaffected status, providing superior supply chain availability and regulatory alignment for new designs and legacy system support. The 0740611081, being obsolete and RoHS non-compliant, should be replaced with the 0740611004 in all applications where regulatory requirements or long-term availability are considerations.

Both parts share identical connector geometry, pitch, contact ratings, and physical specifications, ensuring direct PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 0740611004 be used as a direct replacement for the 0740611081 without PCB redesign?

A: Yes. Both parts are identical in connector type, position count, pitch, mounting method, and electrical ratings. No PCB layout changes are required.

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

A: The 0740611004 is the active production equivalent of the obsolete 0740611081. The substitute part offers improved regulatory compliance (ROHS3 compliant versus RoHS non-compliant) and better supply chain availability. All functional and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The 0740611004 is supplied in tube packaging. The original part packaging specification was not provided. Confirm packaging requirements for your procurement process.

Q: What electrical parameters must match for substitution?

A: Current rating (3A), voltage rating (120V), contact finish (gold plated), and flammability rating (UL94 V-0) must remain constant. Both parts meet these specifications.

Q: Is the 0740611081 still available for purchase?

A: The 0740611081 is classified as obsolete. The 0740611004 is the active substitute with confirmed inventory availability.
