Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0366330024 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 20-position, 2-row header with 0.165" (4.20mm) pitch and row spacing
• Mounting & Orientation: Through-hole, right-angle mounting
• Shrouding Design: Shrouded 4-wall construction
• Contact System: Male pin contacts with brass material and tin/nickel finish options
• Termination Method: Solder termination with locking ramp fastening
• Insulation Specifications: Polyamide (PA46) nylon 4/6 material with UL94 V-0 rating
• Compliance: ROHS3 compliance and MSL 1 rating

The substitute part Molex 0874272002 meets all these critical parameters while offering the advantage of active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874272002 is a direct functional equivalent to the obsolete 0366330024. Both parts share identical electrical and mechanical specifications within the Mini-Fit Jr 87427 series, including connector configuration, pitch spacing, mounting orientation, and material compliance.

The primary distinction is product status: the 0874272002 maintains active manufacturing status, ensuring long-term availability and supply chain reliability. The 0366330024, classified as obsolete, presents supply constraints for new production and future maintenance requirements.

Both parts meet ROHS3 compliance and UL94 V-0 flammability standards. The contact finish difference (nickel on 0366330024 versus tin on 0874272002) does not affect functional compatibility, as both finishes provide equivalent electrical performance and corrosion resistance within the specified applications.

For new designs and ongoing production, the 0874272002 is the appropriate selection. For legacy system maintenance where original part specifications are mandated, the 0366330024 remains available in current inventory.

Frequently Asked Questions (FAQ)

Q: Are the Molex 0366330024 and 0874272002 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 20-position, 2-row configuration with 0.165" (4.20mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, and solder termination. PCB footprints and mating interface dimensions are identical.

Q: What is the significance of the contact finish difference between the two parts?

A: The 0366330024 features nickel mating contact finish, while the 0874272002 uses tin. Both finishes provide equivalent electrical conductivity and corrosion resistance for general purpose, industrial, and telecommunications applications. The difference does not affect signal integrity or connector performance.

Q: Can the 0874272002 be used as a direct replacement in existing assemblies designed for the 0366330024?

A: Yes. The 0874272002 is functionally equivalent and maintains all critical electrical and mechanical parameters. No design modifications are required for substitution.

Q: Why is the 0366330024 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The 0874272002 represents the current active equivalent within the Mini-Fit Jr 87427 series.

Q: Are there packaging differences between these parts?

A: Yes. The 0366330024 is supplied in bulk packaging, while the 0874272002 is supplied in tray packaging. This affects handling and storage but does not impact electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0366330024 and 0874272002 are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification.
