Molex 0334820402 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334820402 is a 4-position rectangular connector plug housing with 0.138" (4.60mm) pitch, designed for crimp termination in free-hanging inline applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing procurement and system maintenance. The housing features sealed construction with a locking ramp fastening mechanism and is compliant with ROHS3 standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0334820402 are determined by strict equivalence across the following critical parameters:

• Connector Type: Plug
• Contact Type: Male Blade
• Number of Positions: 4
• Pitch: 0.138" (4.60mm)
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Features: Sealed
• Series: MX150 33482
• Base Product Number: 033482

All three substitute parts (0334824001, 0334824103, 0334824104) maintain identical electrical and mechanical specifications to the main part. Variations exist only in color (Black vs. Gray) and product status (Active vs. Obsolete), with two substitutes showing differences in REACH compliance status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are electrically and mechanically equivalent to the Molex 0334820402 and are suitable for direct replacement in applications requiring a 4-position, 4.60mm pitch rectangular connector plug housing with crimp termination.

0334824001 is recommended for applications where black housing color is acceptable or preferred. This part carries Active product status and REACH Unaffected compliance, ensuring long-term availability and regulatory alignment.

0334824103 maintains the original gray housing color of the main part and carries Active product status with REACH Unaffected compliance, providing the closest functional and aesthetic match to the obsolete 0334820402.

0334824104 also provides gray housing color and Active product status but carries REACH Affected compliance status. This part is suitable for applications where REACH compliance requirements do not restrict its use.

Selection between these three substitutes should be based on color requirements, REACH compliance obligations, and inventory availability rather than electrical or mechanical performance, as all three are parametrically equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 0334824001 (black) be used as a direct replacement for the 0334820402 (gray)?

A: Yes. The 0334824001 is parametrically equivalent across all electrical and mechanical specifications. The only difference is housing color. Substitution is valid if color is not a functional requirement in your application.

Q: What is the difference between the three substitute parts?

A: The three substitutes differ only in color (0334824001 is black; 0334824103 and 0334824104 are gray) and REACH compliance status (0334824001 and 0334824103 are REACH Unaffected; 0334824104 is REACH Affected). All other parameters are identical.

Q: Are these parts compatible with the same mating connectors as the 0334820402?

A: Yes. All substitute parts maintain the same pitch (0.138" / 4.60mm), number of positions (4), connector type (Plug), and fastening mechanism (Locking Ramp), ensuring compatibility with existing mating receptacles designed for the original part.

Q: Why is the original part obsolete while the substitutes are active?

A: The 0334820402 has been discontinued by Molex, but the equivalent designs within the MX150 33482 series remain in active production. The substitute parts represent the current manufacturing alternatives for this connector configuration.

Q: Do I need to verify REACH compliance before selecting a substitute?

A: If your application or supply chain has REACH compliance requirements, select either 0334824001 or 0334824103 (both REACH Unaffected). If REACH compliance is not a constraint, 0334824104 is also suitable.

Q: Are contacts included with these connector housings?

A: No. All parts in this comparison are housings only. Contacts must be procured separately and crimped into the housing according to Molex specifications.
