Substitute Part Grouping Explanation

Substitution of the Molex 0740592502 is determined by strict equivalence across the following critical parameters:

  • Connector type, style, and position count (Header, Male Pins; VHDM, Guide Right; 150 positions)
  • Physical configuration (6 rows × 25 columns; 0.079" pitch)
  • Mounting and termination method (Through Hole; Press-Fit)
  • Electrical ratings (2A current; 120V voltage)
  • Contact material and finish (Gold plating)
  • Operating temperature range (-55°C to 105°C)
  • Shielding requirement

The substitute part 0740598502 maintains identical electrical, mechanical, and dimensional specifications across all these parameters, establishing direct functional equivalence. The primary distinction between the main part and substitute is product status and regulatory compliance.
