Key Parameters

Substitute Part Grouping Explanation

The Molex 0874270802 qualifies as a direct substitute for the 0366330042 based on the following critical parameters:

• Connector Configuration: Both parts maintain identical 8-position, 2-row layout with 0.165" (4.20mm) mating pitch and row spacing
• Physical Form Factor: Both feature right-angle through-hole mounting with shrouded 4-wall construction
• Contact Specifications: Identical male pin contact type, brass material, and tin finish on mating surfaces
• Insulation Properties: Both use Polyamide (PA46) Nylon 4/6 insulation with matching 0.394" (10.00mm) insulation height
• Compliance Standards: Both maintain UL94 V-0 flammability rating and ROHS3 compliance
• Termination Method: Both employ solder termination with locking ramp fastening

The primary distinction is product status: the 0366330042 is obsolete, while the 0874270802 is active with significantly higher inventory availability (20,245 units versus 942 units).

Parameter Comparison
