Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0366330033 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Type: Header with Male Pin contacts
• Position Configuration: 2 positions in 2 rows
• Row Spacing: 0.165" (4.20mm) mating spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding & Fastening: Shrouded 4-wall design with locking ramp fastening
• Physical Dimensions: Contact post length 0.130" (3.30mm), insulation height 0.504" (12.80mm)
• Material & Finish: Brass contacts with tin plating, polyamide insulation
• Compliance: UL94 V-0 flammability rating, ROHS3 compliance

The substitute part Molex 0874270242 maintains identical electrical and mechanical specifications across all these parameters, differing only in product status (active vs. obsolete) and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874270242 is the direct functional equivalent of the obsolete Molex 0366330033. Both parts are manufactured by Molex within the Mini-Fit Jr 87427 series and maintain identical electrical and mechanical specifications. The primary distinction is product status: the 0366330033 is obsolete while the 0874270242 is active in production.

For new designs and ongoing production requiring this connector type, the 0874270242 is the appropriate selection. Both parts carry ROHS3 compliance and UL94 V-0 flammability certification, meeting industrial and telecommunications application requirements. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage and handling.

The 0874270242 is supplied in bulk packaging, which may differ from the original part's packaging configuration. Verify packaging requirements for your specific procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874270242 directly replace the 0366330033 in existing designs?

A: Yes. The 0874270242 is electrically and mechanically identical to the 0366330033 across all specified parameters, including connector type, position configuration, row spacing, mounting method, termination type, shrouding, fastening mechanism, contact dimensions, materials, and finishes. Direct substitution is supported without design modification.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The 0366330033 is obsolete, while the 0874270242 is an active production part. The 0874270242 is supplied in bulk packaging. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical compliance certifications: ROHS3 compliance and UL94 V-0 flammability rating. Both have MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints.

Q: What applications are these connectors suitable for?

A: These rectangular connectors are specified for General Purpose, Industrial, and Telecommunications applications. The through-hole solder termination and shrouded 4-wall design with locking ramp fastening provide mechanical stability and environmental protection suitable for these application categories.

Q: Does packaging affect compatibility?

A: Packaging does not affect electrical or mechanical compatibility. The 0874270242 is supplied in bulk packaging. Verify that bulk packaging meets your procurement, storage, and assembly requirements before selection.

Q: What is the row spacing specification?

A: The row spacing (mating) is 0.165" (4.20mm). This dimension is critical for mating connector alignment and is identical between both parts.
