Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0444720256 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and mating configuration (Header, Male Pin, Board to Cable/Wire)
• Physical dimensions: 2 positions, 2 rows, 0.165" (4.20mm) row spacing
• Mounting and termination method: Through Hole, Solder, Locking Ramp fastening
• Shrouding design: Shrouded - 4 Wall
• Contact geometry and materials: Square shape, Copper Alloy with Tin finish
• Insulation specifications: Polyamide (PA66), Nylon 6/6, Natural color
• Regulatory compliance: ROHS3 Compliant, MSL 1

The substitute part Molex 0444720256 meets all these criteria while offering active product status and improved material flammability rating.

Parameter Comparison

Engineering Selection Recommendations
