Substitute Part Grouping Explanation

Substitution of the Molex 0366330045 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 22 positions, 2 rows, 0.165" (4.20mm) mating pitch and row spacing
• Mounting and Orientation: Through-hole, right-angle mounting
• Shrouding Design: Shrouded 4-wall construction
• Contact Specifications: Male pin, brass material, tin finish
• Termination Method: Solder termination with locking ramp fastening
• Insulation Properties: Polyamide (PA46) nylon 4/6 material, beige color
• Compliance Standards: UL94 V-0 flammability rating, ROHS3 compliance

The substitute part Molex 0874272202 maintains identical electrical and mechanical specifications across all these parameters. The primary distinction is product status: the substitute is active production, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874272202 is the direct functional equivalent of the obsolete Molex 0366330045. Both parts are manufactured by Molex within the Mini-Fit Jr 87427 series and maintain identical electrical and mechanical specifications. The substitute part is currently in active production status, ensuring supply chain continuity and long-term availability.

Both parts meet ROHS3 compliance requirements and carry UL94 V-0 flammability certification, satisfying regulatory and safety standards for industrial and telecommunications applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part.

The primary operational difference is packaging: the substitute part is supplied in tray format, whereas the original part packaging specification was not provided. This distinction affects logistics and handling but does not impact functional performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874272202 be used as a direct replacement for the 0366330045?

A: Yes. Both parts are identical in all electrical and mechanical parameters, including connector configuration, contact specifications, mounting type, and material composition. The substitute is the active production equivalent of the obsolete original part.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution is valid when the following parameters match: 22-position, 2-row configuration; 0.165" (4.20mm) mating pitch and row spacing; through-hole right-angle mounting; shrouded 4-wall design; male pin contacts; brass material with tin finish; solder termination; and polyamide nylon 4/6 insulation.

Q: Does the packaging difference affect connector performance?

A: No. Packaging format (tray versus unspecified) is a logistics consideration only and does not affect electrical performance, mechanical fit, or functional compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the original and substitute parts are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting current regulatory requirements for industrial and telecommunications applications.

Q: Why is the original part listed as obsolete?

A: The Molex 0366330045 has been superseded by the active production part 0874272202. The substitute maintains full functional equivalence while ensuring ongoing supply availability.
