Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740619021 is determined by strict equivalence across the following critical parameters:

• Connector type and style: Header, Male Pins with VHDM, Guide Left configuration
• Position count and arrangement: 80 positions in 8 rows × 10 columns
• Electrical specifications: 3A current rating, 120V voltage rating
• Physical specifications: 0.079" (2.00mm) pitch, through-hole mounting, press-fit termination
• Material and contact properties: Gold-plated contacts at 30.0µin thickness, UL94 V-0 flammability rating, shielded design
• Regulatory compliance: ROHS3 compliant, REACH unaffected

The substitute part Molex 0740611004 meets all these criteria while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740611004 is the direct functional equivalent of the 0740619021. Both parts are manufactured by Molex within the same VHDM 74061 series and share identical electrical, mechanical, and material specifications. The primary distinction is product status: the 0740619021 is obsolete while the 0740611004 maintains active status with manufacturer support.

For new designs or production continuity, the 0740611004 is the appropriate selection. This part carries full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The active product status ensures ongoing availability, technical support, and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Are the 0740619021 and 0740611004 electrically and mechanically interchangeable?

A: Yes. Both parts are identical in connector type, position count, pitch, current rating, voltage rating, contact finish, and termination method. They are direct functional equivalents within the VHDM 74061 series.

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