Molex 0740621024 VHDM 80-Position Backplane Connector Header

Part Overview

The Molex 0740621024 is an 80-position backplane connector header featuring male pins configured in an 8×10 matrix with VHDM guide-right orientation. This component is designed for through-hole PCB mounting applications requiring shielded, high-density interconnection in industrial and telecommunications equipment.

The 0740621024 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support long-term product serviceability where original components are no longer manufactured or available in production quantities.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740621024 is determined by strict equivalence across the following critical parameters:

• Connector type, style, and orientation (Header, Male Pins; VHDM, Guide Right)
• Position count and matrix configuration (80 positions; 8×10 arrangement)
• Pitch specification (0.079" / 2.00mm)
• Electrical ratings (3A current; 120V voltage)
• Mounting and termination method (Through Hole; Press-Fit)
• Environmental and material specifications (UL94 V-0; -55°C to +105°C)
• Contact finish and shielding (Gold plated; Shielded)

The substitute part must belong to the same VHDM 74062 series and maintain full mechanical and electrical compatibility with the original design. Packaging format and product status (active vs. obsolete) do not affect functional substitutability but influence availability and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740621001 is a direct functional equivalent to the 0740621024 across all critical electrical, mechanical, and environmental parameters. Both components are identical in connector configuration, pin count, pitch, current and voltage ratings, operating temperature range, and contact specifications.

The primary distinction is product lifecycle status: the 0740621024 is obsolete, while the 0740621001 is in active production. This difference carries significant implications for supply chain continuity and regulatory compliance. The 0740621001 carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions, whereas the 0740621024 is marked as RoHS non-compliant. For new designs or long-term production requirements, the 0740621001 is the appropriate selection.

The 0740621001 is supplied in tube packaging, which may differ from the original part's packaging format. This distinction affects handling, storage, and integration into automated assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0740621001 be used as a direct replacement for the 0740621024 in existing designs?

A: Yes. The 0740621001 is electrically and mechanically equivalent to the 0740621024. All connector specifications, pin configurations, electrical ratings, and environmental operating parameters are identical. No design modifications are required for substitution.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 0740621024 is no longer manufactured by Molex. The 0740621001 is in active production and represents the current equivalent part. For new production runs, long-term supply agreements, or designs requiring extended component availability, the 0740621001 is the appropriate choice.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance status does not affect electrical or mechanical compatibility. However, the 0740621001's ROHS3 compliance makes it suitable for applications subject to current environmental regulations, while the 0740621024's non-compliant status may restrict its use in regulated markets or new product certifications.

Q: Are there packaging considerations when switching from 0740621024 to 0740621001?

A: The 0740621001 is supplied in tube packaging. If the original part used different packaging, assembly line integration, component handling, and storage procedures may require adjustment. The functional component itself remains unchanged.

Q: What is the pitch specification, and why is it important for substitution?

A: Both parts feature a 0.079" (2.00mm) pitch, which defines the center-to-center spacing between connector pins. Pitch equivalence is critical for PCB footprint compatibility and ensures the substitute part will mount correctly without design rework.

Q: Are both parts suitable for the same current and voltage applications?

A: Yes. Both the 0740621024 and 0740621001 are rated for 3A current and 120V voltage. They are suitable for identical electrical applications within these specifications.
