Molex 0334820644 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334820644 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 substitute parts essential for ongoing system support and component procurement.

The housing features a locking ramp fastening mechanism, sealed design with protective cap, and is manufactured in black polyamide material. As an obsolete product, direct replacement with active production alternatives is necessary for new designs and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334820644 is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug housing only
• Number of Positions: 6 positions
• Pitch: 0.138" (4.60mm)
• Number of Rows: 2 rows
• Contact Type: Male Blade
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Series Compatibility: MX150 33482 series

The substitute part Molex 0334823644 maintains full equivalence across all critical electrical and mechanical parameters. The primary difference is the housing color (yellow versus black) and active product status, which does not affect functional interchangeability in applications where the original black housing is not a design constraint.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0334823644 is the direct functional equivalent for the obsolete 0334820644. Both components maintain identical electrical and mechanical specifications within the MX150 33482 series, with ROHS3 compliance and unlimited moisture sensitivity rating.

Selection of the 0334823644 substitute is appropriate for applications where housing color differentiation is not a critical design requirement. The active product status of the 0334823644 ensures long-term availability and supply chain continuity compared to the obsolete original part.

Both components are compatible with the same crimp contact set and mating receptacle housings within the MX150 series. Procurement of the substitute part eliminates obsolescence risk while maintaining full functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334823644 directly replace the 0334820644 in existing assemblies?

A: Yes, the 0334823644 is a direct functional replacement. Both housings maintain identical pitch (4.60mm), position count (6), row configuration (2), and crimp termination specifications. The primary difference is housing color (yellow versus black). Compatibility is maintained with all standard MX150 series crimp contacts and mating receptacles.

Q: Does the color difference between black and yellow housings affect electrical performance?

A: No. Housing color is a visual identification feature only and does not affect electrical performance, impedance, or signal integrity. Both housings provide equivalent sealed protection and locking ramp fastening.

Q: Are the crimp contacts interchangeable between these two housings?

A: Yes. Both the 0334820644 and 0334823644 accept the same crimp contact specifications within the MX150 series. Contact selection is independent of housing color.

Q: What is the significance of the obsolete status of the 0334820644?

A: Obsolete status indicates that Molex has discontinued production of this part. The 0334823644 substitute is in active production, ensuring availability for new procurement and long-term supply chain reliability.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 0334820644 and 0334823644 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), meeting current environmental and regulatory requirements.
