Molex 0740591012 VHDM 60-Position Backplane Connector Header

Part Overview

The Molex 0740591012 is a 60-position backplane connector header featuring male pins configured in a 6×10 matrix with VHDM guide-right orientation. 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 that maintain electrical and mechanical compatibility while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740591012 is determined by strict equivalence across the following critical parameters:

• Connector Type and Style: Header with male pins, VHDM guide-right configuration
• Position Count and Matrix: 60 positions in 6×10 arrangement
• Pitch Specification: 0.079" (2.00mm) center-to-center spacing
• Electrical Ratings: 2A current rating and 120V voltage rating
• Mounting and Termination: Through-hole press-fit termination
• Physical Features: Shielded design with gold contact finish
• Environmental Specifications: Operating temperature range -55°C to +105°C, UL94 V-0 flammability rating

The identified substitute parts (0740591001 and 0740599002) maintain complete electrical and mechanical equivalence across all specified parameters. Differences exist only in product status (active vs. obsolete), RoHS compliance certification (ROHS3 Compliant vs. non-compliant), and packaging format (Tube and Bulk vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (0740591001 and 0740599002) provide complete functional and mechanical equivalence to the obsolete 0740591012. Selection between alternatives should be based on the following criteria:

0740591001 is recommended for applications requiring ROHS3 compliance certification with controlled packaging in tube format. This part maintains active product status with Molex, ensuring long-term availability and supply chain stability.

0740599002 is recommended for high-volume applications where bulk packaging reduces per-unit cost and packaging waste. This part also carries ROHS3 compliance certification and active product status.

Both substitute parts eliminate the compliance and obsolescence risks associated with the original 0740591012 while maintaining identical electrical performance, mechanical fit, and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts electrically identical to the 0740591012? A: Yes. Both 0740591001 and 0740599002 maintain identical current rating (2A), voltage rating (120V), operating temperature range (-55°C to +105°C), and contact specifications (gold finish, 30.0µin thickness).

Q: What is the primary reason to transition from 0740591012? A: The 0740591012 is classified as obsolete. The substitute parts (0740591001 and 0740599002) are active products with ROHS3 compliance certification, ensuring continued availability and regulatory alignment.

Q: Are the mechanical dimensions and mounting specifications identical? A: Yes. Both substitutes maintain the same 60-position configuration in a 6×10 matrix, 0.079" (2.00mm) pitch, through-hole press-fit termination, VHDM guide-right orientation, and shielded design.

Q: What is the difference between 0740591001 and 0740599002? A: The primary difference is packaging format. 0740591001 is supplied in tube packaging, while 0740599002 is supplied in bulk packaging. Both are electrically and mechanically equivalent with identical ROHS3 compliance and active product status.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. Both substitute parts are direct mechanical and electrical replacements. PCB footprints, connector mating interfaces, and electrical performance are identical.

Q: Are there any compliance differences between the main part and substitutes? A: Yes. The 0740591012 is RoHS non-compliant, while both 0740591001 and 0740599002 are ROHS3 compliant. Both maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.
