Substitute Part Grouping Explanation

The Molex 0874272442 qualifies as a direct functional substitute for the 0366330029 based on strict parameter equivalence across all critical electrical and mechanical specifications. Substitution is valid when the following parameters match identically:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (24)
• Number of rows (2)
• Pitch - mating (0.165" / 4.20mm)
• Row spacing - mating (0.165" / 4.20mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact finish - mating (Tin)
• Insulation material (Polyamide PA46, Nylon 4/6)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)
• Moisture sensitivity level (1 - Unlimited)

The 0874272442 maintains full compatibility with existing PCB footprints, mating connectors, and assembly processes designed for the 0366330029.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874272442 is the direct equivalent substitute for the obsolete 0366330029. Both parts are manufactured by Molex within the same Mini-Fit Jr 87427 series and maintain identical electrical and mechanical specifications across all critical parameters.

The 0874272442 carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and identical regulatory certifications (EAR99, HTSUS 8536.69.4040), supporting use in regulated industrial, telecommunications, and general-purpose applications.

The primary distinction is packaging: the 0874272442 is supplied in tray format, whereas the original part number does not specify packaging. This difference does not affect functional compatibility or performance in board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can the 0874272442 be used as a direct replacement for the 0366330029 in existing designs?

A: Yes. The 0874272442 is functionally identical to the 0366330029 across all electrical and mechanical parameters. It maintains the same 24-position, 2-row configuration with 0.165" (4.20mm) pitch and mating row spacing. PCB footprints, mating connectors, and assembly processes designed for the 0366330029 are fully compatible with the 0874272442.

Q: What is the significance of the product status difference?

A: The 0366330029 is classified as obsolete, indicating it is no longer manufactured or supported by Molex. The 0874272442 carries active product status, confirming current production and availability. For new designs and ongoing production, the 0874272442 is the recommended part number.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts maintain identical compliance certifications: ROHS3 Compliant, UL94 V-0 material flammability rating, EAR99 export classification, and HTSUS code 8536.69.4040. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: Does the tray packaging of the 0874272442 affect compatibility?

A: No. Packaging format does not affect electrical or mechanical compatibility. The tray packaging of the 0874272442 is a supply and handling consideration only and does not impact performance or fit in applications designed for the 0366330029.

Q: What are the key parameters that define substitution eligibility for this connector type?

A: Substitution eligibility is determined by matching: connector type, contact type, number of positions, number of rows, mating pitch, row spacing, mounting type, shrouding configuration, termination method, contact finish, insulation material, and flammability rating. The 0874272442 matches all these parameters with the 0366330029.
