Molex 0366330020 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0366330020 is a through-hole, right-angle rectangular connector header designed for board-to-cable/wire applications. This connector features a 4-position configuration with 0.165" (4.20mm) pitch spacing and is part of the Mini-Fit Jr 87427 series. The part is currently classified as obsolete, making identification of functionally equivalent active alternatives essential for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0366330020 is determined by strict equivalence across the following critical parameters:

  • Connector Configuration: 4-position, 2-row header with 0.165" (4.20mm) pitch and row spacing
  • Mounting & Orientation: Through-hole, right-angle mounting
  • Shrouding & Contact Type: Shrouded 4-wall design with male pin contacts
  • Material & Finish Specifications: Brass contacts with tin finish, polyamide insulation, UL94 V-0 rated
  • Termination Method: Solder termination with locking ramp fastening
  • Compliance Standards: ROHS3 compliant, MSL 1 rating

The substitute part Molex 0874270402 meets all these criteria and is classified as an active product, providing a direct functional replacement for the obsolete 0366330020.
