Substitute Part Grouping Explanation

Substitution of the Molex 0366330044 is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: Mini-Fit Jr 87427 header configuration
• Position Count & Row Configuration: 18 positions in 2-row arrangement
• Pitch Specifications: 0.165" (4.20mm) mating pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding Configuration: Shrouded with 4-wall design
• Contact System: Male pin contacts with tin-plated brass construction
• Termination Method: Solder termination
• Insulation Properties: Polyamide (PA46) material with UL94 V-0 rating

The substitute part Molex 0874271802 maintains full electrical and mechanical compatibility across all specified parameters while offering the advantage of active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874271802 is a direct functional equivalent to the obsolete Molex 0366330044. Both components are ROHS3 compliant and maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, and material composition.

The primary distinction is product status: the 0874271802 maintains active manufacturing status with significantly higher inventory availability (8176 pieces versus 1113 pieces for the obsolete part). The substitute is supplied in tray packaging, which is standard for active production components.

For new designs or component replenishment, the 0874271802 is the appropriate selection. For legacy system maintenance requiring exact original specifications, both parts are functionally interchangeable within the Mini-Fit Jr 87427 series ecosystem.

Frequently Asked Questions (FAQ)

Q: Are the 0366330044 and 0874271802 mechanically interchangeable?

A: Yes. Both connectors share identical dimensions, pitch specifications (0.165" / 4.20mm), row spacing, mounting orientation (right-angle through-hole), and shrouding configuration (4-wall shrouded). They are direct mechanical equivalents.

Q: What is the primary reason for substitution?

A: The 0366330044 is obsolete. The 0874271802 is the active equivalent from Molex, offering continued manufacturing support and superior inventory availability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, carry UL94 V-0 material flammability rating, and have MSL 1 (Unlimited) moisture sensitivity classification.

Q: Are there packaging differences between these parts?

A: The 0366330044 packaging is not specified in available documentation. The 0874271802 is supplied in tray packaging, which is standard for active production components.

Q: Can the 0874271802 be used as a direct replacement in existing assemblies?

A: Yes. The 0874271802 maintains full electrical and mechanical compatibility with the 0366330044 across all specified parameters and can be used as a direct replacement without design modification.

Q: What contact configuration do these connectors use?

A: Both connectors feature male pin contacts with tin-plated brass construction. The contact finish thickness is 100.0µin (2.54µm) on both mating and post surfaces.
