Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0740612582 is determined by strict equivalence across the following critical parameters:

Position count, connector type, connector style, pitch, row/column configuration, mounting method, termination type, shielding, contact finish, current rating, voltage rating, and flammability rating must remain identical. The substitute part must belong to the same VHDM 74061 series and maintain mechanical and electrical compatibility with the original design.

The Molex 0740612501 qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0740612501 is the designated substitute for the obsolete Molex 0740612582. Both components maintain identical electrical and mechanical specifications, ensuring direct compatibility in existing designs.
