Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Molex 0366330021 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and row configuration (10 positions, 2 rows)
• Pitch and row spacing (0.165" / 4.20mm)
• Mounting style (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact material and finish (Brass with Tin plating)
• Insulation material (Polyamide PA46, Nylon 4/6)
• Compliance certifications (UL94 V-0, ROHS3)

The substitute part Molex 0874271002 maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being active product status and standard tray packaging availability.

Parameter Comparison
