Molex 0334820642 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334820642 is a 6-position rectangular connector plug housing with 4.60mm pitch, designed for crimp contact termination in free-hanging inline applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The housing features a locking ramp fastening mechanism and sealed design with integrated cap cover. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or mechanical modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334820642 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Plug housing with male blade contacts
• Electrical Interface: 6-position, 4.60mm pitch, 2-row configuration
• Mechanical Interface: Free-hanging inline mounting with crimp termination
• Fastening Mechanism: Locking ramp system
• Environmental Sealing: Sealed housing design
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The substitute part Molex 0334823642 maintains all critical electrical and mechanical parameters. The only permitted variation is housing color (gray versus black), which does not affect electrical performance or mechanical fit. Both parts share the identical base product number (033482) and series designation (MX150 33482), confirming functional equivalence within the MX150 connector family.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0334823642 is the direct substitute for the obsolete 0334820642. Selection of this substitute is supported by:

• Product Status: The substitute part is active and currently manufactured, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, meeting environmental and reliability standards.
• Functional Equivalence: All electrical and mechanical parameters are identical, enabling direct replacement without circuit modification or mechanical redesign.
• Series Continuity: Both parts belong to the MX150 33482 series, confirming compatibility within the established connector family.

The housing color difference (gray versus black) is a cosmetic variation that does not affect electrical performance, mechanical fit, or environmental sealing capability. Selection between these parts may be determined by system documentation, assembly process requirements, or visual identification standards.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334823642 be used as a direct replacement for the 0334820642 without any modifications?

A: Yes. The substitute part maintains identical electrical and mechanical specifications across all critical parameters: connector type, contact configuration, pitch, row count, mounting method, termination type, and fastening mechanism. Direct substitution is supported without circuit or mechanical changes.

Q: What is the difference between the black (0334820642) and gray (0334823642) housing versions?

A: The housing color is the only difference between these parts. Both versions provide identical electrical performance, mechanical fit, sealing capability, and environmental protection. Color selection is determined by system documentation or assembly requirements.

Q: Why is the 0334820642 listed as obsolete?

A: The 0334820642 has been discontinued by Molex. The 0334823642 (gray version) is the active production equivalent within the MX150 33482 series and is recommended for new designs and ongoing procurement.

Q: Are the contacts included with these connector housings?

A: No. Both the main part and substitute are housings only. Contacts must be procured separately and crimped into the housing according to Molex specifications.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting identical environmental and reliability requirements.

Q: What is the pitch specification, and why is it important for substitution?

A: The pitch is 0.138" (4.60mm), representing the center-to-center distance between contact positions. This specification must be identical for mechanical and electrical compatibility. Both parts share this specification.
