Molex 0366330041 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0366330041 is a through-hole, right-angle rectangular connector header designed for board-to-cable/wire applications. This connector features 6 positions arranged in 2 rows with a 0.165" (4.20mm) pitch and shrouded 4-wall design. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0366330041 is determined by strict equivalence across the following critical parameters:

• Connector type (Header), contact type (Male Pin), and style (Board to Cable/Wire)
• Position count (6) and row configuration (2 rows)
• Mating pitch and row spacing (0.165" / 4.20mm)
• Mounting method (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder) and fastening type (Locking Ramp)
• Contact material (Brass) and finish specifications (Tin plating)
• Insulation material (Polyamide PA46, Nylon 4/6) and physical dimensions
• Compliance certifications (UL94 V-0, ROHS3, REACH Unaffected)

The substitute part 0874270602 maintains complete equivalence across all specified parameters, with the primary distinction being active product status and alternative packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874270602 is the direct functional equivalent of the obsolete 0366330041. Both components are manufactured by Molex within the Mini-Fit Jr 87427 series and maintain identical electrical and mechanical specifications across all critical parameters.

The 0874270602 is classified as an active product with current manufacturing support, whereas the 0366330041 is obsolete. For new designs and ongoing production requiring this connector type, the 0874270602 should be selected as the primary component. Both parts maintain equivalent compliance certifications including UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status, ensuring regulatory equivalence.

The packaging difference (tray for 0874270602 versus unspecified for 0366330041) does not affect functional compatibility and relates only to supply chain and inventory management considerations.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874270602 directly replace the 0366330041 in existing applications?

A: Yes. The 0874270602 maintains complete electrical and mechanical equivalence to the 0366330041 across all specified parameters including connector type, position count, pitch, mounting method, contact materials, and finish specifications. Direct substitution is supported without circuit design modifications.

Q: What is the primary reason for substituting the 0366330041?

A: The 0366330041 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 0874270602 is an active product with current manufacturing support and higher inventory availability, making it the appropriate choice for ongoing production and maintenance applications.

Q: Are there compliance differences between these parts?

A: No. Both the 0366330041 and 0874270602 maintain identical compliance certifications: UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status. Regulatory equivalence is maintained.

Q: Does the packaging difference affect compatibility?

A: No. The packaging difference (tray for 0874270602) relates to supply chain and inventory management only. The connector itself maintains identical form, fit, and function. Packaging does not affect circuit board integration or mating performance.

Q: Are the contact specifications identical?

A: Yes. Both parts use brass contacts with tin plating at 100.0µin (2.54µm) thickness on both mating and post surfaces. Contact material, finish type, and thickness specifications are identical.

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

A: Substitution is determined by equivalence in connector type (Header), contact type (Male Pin), position count (6), row configuration (2 rows), mating pitch (0.165" / 4.20mm), mounting method (Through Hole, Right Angle), shrouding design (Shrouded - 4 Wall), termination method (Solder), and contact material and finish specifications. All these parameters are identical between the two parts.
