Molex 0740611019 VHDM 80-Position Backplane Connector Header

Part Overview

The Molex 0740611019 is an 80-position backplane connector header featuring male pins configured in an 8×10 matrix with VHDM style and left-side guide. This through-hole component is designed for PCB-mounted applications requiring shielded connectivity with gold-plated contacts. The part is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740611019 is determined by strict equivalence across the following critical parameters:

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

The Molex 0740611004 meets all these criteria and belongs to the same VHDM 74061 series, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct substitute for the obsolete 0740611019. Both components share identical mechanical and electrical specifications within the VHDM 74061 series. The primary distinction is product lifecycle status: the 0740611004 is in active production and carries ROHS3 compliance certification, whereas the 0740611019 is obsolete and non-compliant with current environmental regulations.

The minor variation in contact finish thickness (30.0µin versus 50.0µin) remains within acceptable engineering tolerances for gold-plated connector contacts and does not affect functional performance or reliability in the specified electrical environment (3A, 120V).

Selection of the 0740611004 is appropriate for new designs, system upgrades, and replacement procurement where regulatory compliance and supply chain continuity are required.

Frequently Asked Questions (FAQ)

Q: Can the 0740611004 be used as a direct replacement for the 0740611019 in existing assemblies?

A: Yes. Both components are mechanically and electrically identical within the VHDM 74061 series. PCB footprints, mating connector interfaces, and electrical performance are equivalent. No design modifications are required.

Q: What is the significance of the contact finish thickness difference?

A: The 0740611004 features 30.0µin (0.76µm) gold plating compared to 50.0µin (1.27µm) on the 0740611019. Both thicknesses meet industry standards for connector reliability and corrosion resistance. The thinner plating on the active part reflects current manufacturing optimization practices.

Q: Why is the 0740611019 classified as obsolete?

A: Obsolescence typically results from manufacturer lifecycle decisions, supply chain consolidation, or transition to improved variants. The 0740611004 represents the current production equivalent within the same series.

Q: Does the ROHS3 compliance of the 0740611004 affect compatibility?

A: No. ROHS3 compliance indicates the substitute meets environmental and material restrictions applicable to current manufacturing and distribution. This is a regulatory advantage with no impact on mechanical or electrical compatibility.

Q: Are there packaging considerations when switching from 0740611019 to 0740611004?

A: The 0740611004 is supplied in tube packaging, which is standard for this connector category. Verify that receiving, storage, and handling procedures accommodate tube packaging if the original part used different packaging.
