Molex 0334820641 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334820641 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 0334820641 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 0334823641 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 0334823641 is the direct functional equivalent for the obsolete Molex 0334820641. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part carries active product status, ensuring continued availability and manufacturing support. The main part is classified as obsolete, creating supply chain risk for new designs or system maintenance.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL 1 ratings, confirming equivalent environmental and regulatory qualification.

Mechanical & Electrical Interchangeability: All critical parameters—connector type, contact configuration, pitch, row count, mounting method, and fastening mechanism—are identical. The housing color variation (gray versus black) is a cosmetic difference that does not affect electrical performance, mechanical fit, or system functionality.

Base Product Equivalence: Both parts share the identical base product number (033482) and MX150 series designation, confirming they are part of the same connector family with equivalent design specifications.

For new designs or system upgrades, the Molex 0334823641 is the recommended selection. For legacy system maintenance where the original black housing is required, the substitute part's gray color may be considered acceptable based on application-specific requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334823641 be used as a direct replacement for the 0334820641 in existing assemblies?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 6-position, 4.60mm pitch, male blade contacts, crimp termination, locking ramp fastening, and sealed design. The only difference is housing color (gray versus black), which does not affect connector function or fit.

Q: Why is the main part classified as obsolete?

A: Molex has transitioned the 0334820641 to obsolete status. The active substitute part 0334823641 provides continued access to equivalent functionality within the MX150 33482 series.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical electrical specifications: 6 positions, 4.60mm pitch, male blade contact type, and crimp termination. Electrical performance is equivalent.

Q: Does the housing color difference affect mechanical compatibility?

A: No. Housing color is a cosmetic variation only. Mechanical fit, mounting interface, and fastening mechanism are identical between the black (0334820641) and gray (0334823641) versions.

Q: What is the significance of the shared base product number (033482)?

A: The identical base product number confirms both parts are variants within the same connector family. This designation indicates they share the same core design, electrical specifications, and mechanical interface.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Molex 0334820641 and 0334823641 carry ROHS3 compliance certification, confirming equivalent environmental qualification.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Can the substitute part be used in applications requiring the original black housing?

A: The gray housing of the 0334823641 is functionally equivalent. Application-specific requirements regarding housing color should be evaluated based on system design constraints or aesthetic specifications.
