Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0746511002 is determined by strict equivalence across the following critical parameters:

• Connector type and style (Header, Male Pins; VHDM, Guide Right)
• Position count and arrangement (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)
• Shielding requirement
• Contact finish (Gold)
• Flammability rating (UL94 V-0)

The Molex 0740591002 meets all these criteria and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740591002 is the direct substitute for the obsolete 0746511002. Both parts maintain identical electrical, mechanical, and thermal specifications. The primary distinction is product status: the 0740591002 is actively manufactured and supported, whereas the 0746511002 is obsolete.

An additional consideration is regulatory compliance. The 0740591002 carries ROHS3 compliance, whereas the 0746511002 is RoHS non-compliant. For applications subject to RoHS regulations or future compliance requirements, the 0740591002 is the appropriate selection.

Both parts are manufactured by Molex and share the same series designation within the VHDM connector family, ensuring design compatibility and interchangeability in PCB layouts and mating connector applications.

Frequently Asked Questions (FAQ)

Q: Can the 0740591002 be used as a direct replacement for the 0746511002 in existing designs?

A: Yes. The 0740591002 is electrically and mechanically equivalent to the 0746511002. Both parts feature identical position counts, pitch, current and voltage ratings, operating temperature range, and contact specifications. PCB footprints and mating connector interfaces are compatible.

Q: What is the primary reason to transition from the 0746511002 to the 0740591002?

A: The 0746511002 is classified as obsolete and is no longer in active production. The 0740591002 is the active equivalent and ensures long-term availability and supply chain continuity.

Q: Are there differences in packaging between these parts?

A: The 0740591002 is supplied in tube packaging. Packaging differences do not affect electrical or mechanical performance and are relevant only to procurement and handling procedures.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and manufacturing process attribute, not a functional characteristic. Both parts are electrically and mechanically identical. However, for applications in regulated markets or future compliance mandates, the ROHS3-compliant 0740591002 is the recommended choice.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 0746511002 and 0740591002 operate across -55°C to 105°C and carry identical UL94 V-0 flammability ratings.
