Molex 0740591102 VHDM 60-Position Backplane Connector Header

Part Overview

The Molex 0740591102 is a 60-position backplane connector header designed for through-hole PCB mounting. This component features male pins in the VHDM series with a guide-right configuration, shielded design, and gold-plated contacts rated for 2A at 120V operation across an extended temperature range of -55°C to 105°C.

The 0740591102 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740591102 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Right)
• Position count and array configuration (60 positions, 6 rows × 10 columns)
• Pitch specification (0.079" / 2.00mm)
• Mounting method (Through Hole)
• Termination type (Press-Fit)
• Electrical ratings (2A current, 120V voltage)
• Operating temperature range (-55°C to 105°C)
• Material compliance (UL94 V-0)
• Shielded design requirement

The substitute part must maintain identical mechanical and electrical characteristics to ensure direct compatibility in PCB layouts and circuit designs without modification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740591001 is the direct equivalent substitute for the obsolete 0740591102. Both parts are manufactured by Molex within the same VHDM 74059 series and maintain identical mechanical and electrical specifications across all critical parameters.

The primary distinction is product status: the 0740591102 is obsolete, while the 0740591001 is active and currently in production. Additionally, the 0740591001 achieves ROHS3 compliance, whereas the 0740591102 is RoHS non-compliant. This compliance improvement makes the 0740591001 the preferred selection for new designs and ongoing supply requirements.

Both parts are packaged identically for through-hole PCB assembly and require no design modifications for direct substitution. The 0740591001 is available in tube packaging with confirmed inventory of 1007 pieces.

Frequently Asked Questions (FAQ)

Q: Can the 0740591001 be used as a direct replacement for the 0740591102 without PCB redesign?

A: Yes. The 0740591001 maintains identical pitch (0.079" / 2.00mm), position count (60), array configuration (6 rows × 10 columns), mounting type (through-hole), and all electrical ratings. No PCB layout modifications are required.

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

A: The 0740591102 is obsolete; the 0740591001 is active production. The 0740591001 also achieves ROHS3 compliance, while the 0740591102 does not. All mechanical and electrical specifications are identical.

Q: Are there any compatibility concerns with the packaging difference?

A: The 0740591102 was supplied without specified packaging; the 0740591001 is supplied in tube packaging. This packaging difference does not affect component functionality or PCB assembly compatibility.

Q: What electrical parameters must match for substitution?

A: Current rating (2A), voltage rating (120V), operating temperature range (-55°C to 105°C), and contact finish (gold-plated) must remain identical. Both parts meet these requirements.

Q: Is the shielded design maintained in the substitute part?

A: Yes. Both the 0740591102 and 0740591001 feature shielded design with identical contact finish specifications (30.0µin / 0.76µm gold plating).

Q: Why should I select the 0740591001 over the 0740591102?

A: The 0740591001 is the active production equivalent with ROHS3 compliance certification. It ensures ongoing supply availability and meets current regulatory requirements for electronic components.
