Substitute Part Grouping Explanation

Substitution of the Molex 0366330026 is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: Mini-Fit Jr 87427 header configuration
• Position Count & Row Configuration: 16 positions in 2-row arrangement
• Pitch Specifications: 0.165" (4.20mm) mating pitch and row spacing
• Shrouding & Mechanical Form Factor: Shrouded 4-wall design for board-to-cable/wire applications
• Termination Method: Solder termination with locking ramp fastening
• Contact Specifications: Male pin contacts with brass material and tin finish
• Insulation Properties: Polyamide (PA46) nylon 4/6 material with UL94 V-0 rating
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The substitute part Molex 0874271642 maintains identical electrical and mechanical specifications across all these parameters, with the primary distinction being product status (active versus obsolete) and packaging format (tray versus unspecified).

Parameter Comparison
