Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0740611003 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 0740611004 maintains identical specifications in the following key areas:

• Connector type, style, and pin configuration (VHDM, Guide Left, 80 positions)
• Physical dimensions and pitch (0.079" / 2.00mm)
• Electrical ratings (3A current, 120V voltage)
• Contact material and finish (gold plating, 30.0µin thickness)
• Mounting method and termination (through-hole, press-fit)
• Environmental and safety certifications (UL94 V-0, MSL 1)

The substitute part differs only in product status (active versus obsolete) and compliance certifications (RoHS3 compliant and REACH unaffected versus non-compliant), making it a direct functional equivalent for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct substitute for the 0740611003 based on complete electrical and mechanical equivalence. Selection of the substitute part is supported by the following factors:

• The substitute maintains active product status, ensuring long-term availability and manufacturing support
• RoHS3 compliance of the substitute part aligns with current regulatory requirements for electronic components in most markets
• REACH unaffected status of the substitute part eliminates potential supply chain restrictions
• Identical electrical ratings, contact specifications, and mounting characteristics ensure drop-in compatibility in existing PCB designs
• Both parts share the same base product number (074061) and series designation (VHDM 74061), confirming design lineage and functional equivalence

Frequently Asked Questions (FAQ)

Q: Can the 0740611004 be used as a direct replacement for the 0740611003 in existing designs?

A: Yes. The substitute part maintains identical connector type, pin configuration, pitch, electrical ratings, and mounting specifications. No PCB redesign or connector interface modifications are required.

Q: What is the primary difference between these two parts?

A: The 0740611003 is obsolete and non-RoHS compliant, while the 0740611004 is an active product with RoHS3 compliance and REACH unaffected status. All functional and electrical characteristics are identical.

Q: Are there packaging differences between the two parts?

A: The 0740611004 is supplied in tube packaging, while packaging information for the 0740611003 is not specified. This difference does not affect component functionality or compatibility.

Q: What electrical parameters determine substitution eligibility for this connector header?

A: Current rating (3A), voltage rating (120V), contact finish (gold plating at 30.0µin thickness), and flammability rating (UL94 V-0) are the primary electrical parameters. Both parts are identical in these specifications.

Q: What mechanical parameters must match for substitution?

A: Connector type (header, male pins), style (VHDM, guide left), position count (80), pitch (0.079" / 2.00mm), row/column configuration (8×10), mounting type (through-hole), and termination method (press-fit) must all match. The substitute part meets all these requirements.

Q: Is the 0740611004 suitable for new product designs?

A: Yes. The active product status and RoHS3 compliance make the 0740611004 the appropriate choice for new designs requiring this connector specification.
