Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0444722056 is determined by strict equivalence across the following parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (20)
• Number of rows (2)
• Pitch - mating (0.165" / 4.20mm)
• Row spacing - mating (0.165" / 4.20mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Contact shape (Square)
• Insulation material (Polyamide PA66, Nylon 6/6)
• Material flammability rating (UL94 V-2)

The Molex 0444722054 meets all these criteria and is classified as an active product, making it a direct functional equivalent.
