Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740591024 is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Header, Male Pins; VHDM, Guide Right
• Position Count & Configuration: 60 positions in 6×10 arrangement
• Pin Pitch: 0.079" (2.00mm)
• Mounting & Termination: Through Hole, Press-Fit
• Electrical Ratings: 2A current, 120V voltage
• Contact Specifications: Gold finish, 30.0µin thickness
• Environmental Compliance: UL94 V-0 flammability rating
• Operating Temperature: -55°C to 105°C

The identified substitute parts—Molex 0740591001 and Molex 0740599001—maintain complete electrical and mechanical equivalence across all specified parameters. Both substitutes are classified as active products with ROHS3 compliance, addressing the regulatory limitation of the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts—0740591001 and 0740599001—are direct functional equivalents of the obsolete 0740591024. Selection between the two substitutes should be based on inventory availability and packaging requirements, as both maintain identical electrical and mechanical specifications.

The transition from the original RoHS non-compliant part to either ROHS3-compliant substitute addresses regulatory requirements for new production and procurement cycles. Both substitutes are classified as active products with confirmed stock availability, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 0740591001 and 0740599001 electrically and mechanically identical to the original 0740591024?

A: Yes. Both substitutes maintain complete equivalence across all specified electrical parameters (2A current rating, 120V voltage rating, -55°C to 105°C operating range), mechanical configuration (60 positions, 2.00mm pitch, 6×10 arrangement, through-hole press-fit termination), and contact specifications (gold finish, 30.0µin thickness). The connector style, shielding, and flammability rating are identical.

Q: What is the primary difference between the original part and the substitutes?

A: The original 0740591024 is classified as obsolete and RoHS non-compliant. Both substitute parts are active products with ROHS3 compliance, addressing regulatory and supply chain continuity requirements.

Q: Can I use either 0740591001 or 0740599001 interchangeably?

A: Yes. Both parts are functionally equivalent. The primary difference is packaging format: 0740591001 and 0740599001 are supplied in tube packaging, while the original was supplied in bulk. Selection should be based on inventory availability and packaging requirements for your application.

Q: Are there any compatibility considerations for PCB layout or mounting?

A: No. Both substitutes maintain identical through-hole press-fit termination and pin pitch specifications. Existing PCB designs and mounting procedures for the original part are directly compatible with either substitute without modification.

Q: What is the MSL rating for the substitute parts?

A: Both substitutes carry MSL 1 (Unlimited), indicating no moisture sensitivity limitations for storage or handling.
