Molex 0366330046 Equivalent & Substitute Parts

Part Overview

The Molex 0366330046 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features 24 positions across 2 rows with a 0.165" (4.20mm) pitch, shrouded design with 4-wall protection, and solder termination. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in board-to-cable/wire interconnect designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0366330046 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 24-position, 2-row header with 0.165" (4.20mm) mating pitch and row spacing
• Mounting Orientation: Through-hole, right-angle mounting
• Shrouding Design: 4-wall shrouded construction
• Contact Specifications: Male pin contacts with tin finish on brass material
• Termination Method: Solder termination with locking ramp fastening
• Insulation Properties: Polyamide (PA46) nylon 4/6 material with UL94 V-0 flammability rating
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The Molex 0874272402 qualifies as a direct substitute based on identical alignment across all specified parameters. The primary distinction is product status: the 0366330046 is obsolete, while the 0874272402 is active production, with significantly higher inventory availability (10,672 units versus 741 units).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874272402 is the direct functional equivalent to the obsolete Molex 0366330046. Both components are ROHS3 compliant and carry identical electrical and mechanical specifications across all critical parameters. The 0874272402 is the recommended selection for new designs and production continuity due to its active product status and substantially higher inventory availability.

For applications currently using the 0366330046, direct substitution with the 0874272402 requires no design modifications. Both components share identical connector geometry, contact configuration, termination method, and compliance certifications. The packaging difference (tray for the 0874272402 versus unspecified for the 0366330046) does not affect functional performance or board-level compatibility.

Frequently Asked Questions (FAQ)
