Substitute Part Grouping Explanation

Substitution of the Molex 0366330025 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Type: Header with male pins
• Position Configuration: 10 positions in 2 rows
• Pitch Specifications: 0.165" (4.20mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding Design: Shrouded 4-wall configuration
• Material & Finish Specifications: Brass contacts with tin finish; polyamide insulation
• Mechanical Dimensions: Insulation height of 0.504" (12.80mm); square contact shape
• Compliance Standards: UL94 V-0 flammability rating; ROHS3 compliance

The substitute part Molex 0874271042 maintains full electrical and mechanical compatibility across all specified parameters. The primary distinction is product status: the substitute is active and available, whereas the original part is obsolete.
