Molex 0334820401 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334820401 is a 4-position rectangular connector plug housing with 4.60mm pitch, designed for crimp termination in free-hanging inline applications. This component is classified as obsolete, which necessitates identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. Substitute parts must preserve the connector type, contact configuration, pitch, mounting method, and fastening mechanism to ensure direct interchangeability in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334820401 is determined by strict equivalence across the following critical parameters:

• Connector Type: Plug
• Number of Positions: 4
• Pitch: 0.138" (4.60mm)
• Number of Rows: 2
• Contact Type: Male Blade
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Features: Sealed
• Series: MX150 33482
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts maintain these parameters without deviation. Variations in color (Black vs. Gray) and insulation material composition do not affect functional interchangeability, as these are cosmetic and material-grade distinctions within the same product family. Product status transitions from obsolete to active indicate improved availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Molex 0334824001

The 0334824001 is the direct functional equivalent to the obsolete 0334820401, maintaining identical color (Black) and all critical electrical and mechanical parameters. This part carries active product status with the highest inventory availability (23,256 units), ensuring supply chain reliability. ROHS3 compliance and MSL 1 rating are preserved.

Secondary Recommendation: Molex 0334824002

The 0334824002 provides full parametric equivalence with the distinction of gray color and active product status. This part is designated as the manufacturer-recommended substitute and offers substantial inventory (11,442 units). Selection of this part is appropriate when color differentiation is not a design constraint.

Alternative Options: Molex 0334824103 and 0334824104

Both parts maintain complete parametric equivalence and active status. The 0334824103 carries standard REACH status, while the 0334824104 is REACH Affected. Inventory levels are lower (2,129 and 3,379 units respectively), making these suitable for applications where primary options are unavailable. Color is gray for both variants.

All four substitute parts are direct replacements from an electrical and mechanical standpoint. Selection should be based on color requirement, inventory availability, and REACH compliance status for the end application.

Frequently Asked Questions (FAQ)

Q: Can the 0334824002 (gray) directly replace the 0334820401 (black) in my assembly?

A: Yes. The color difference is cosmetic and does not affect electrical or mechanical function. Both parts share identical connector type, position count, pitch, contact configuration, mounting method, and fastening mechanism. Selection between black and gray variants depends solely on design aesthetics or assembly documentation requirements.

Q: Why is the original 0334820401 marked as obsolete?

A: Obsolescence indicates the part is no longer in active production. The substitute parts listed (0334824001, 0334824002, 0334824103, 0334824104) are active equivalents that provide identical functionality with improved supply availability.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All substitute parts maintain identical electrical specifications: 4-position configuration, 4.60mm pitch, male blade contacts, crimp termination, and sealed design. Variations in insulation material composition (Syndiotactic Polystyrene vs. Polyamide/Nylon blends) do not alter electrical performance within the specified operating parameters.

Q: What is the difference between REACH Unaffected and REACH Affected status?

A: REACH Affected status (0334824104) indicates the part contains substances of concern under REACH regulations but remains compliant. REACH Unaffected status (0334824001, 0334824002, 0334824103) indicates no such substances are present. Both statuses are compliant; selection depends on supply chain and regulatory documentation requirements for your end market.

Q: Can I mix substitute parts in the same assembly?

A: Yes. All substitute parts are parametrically equivalent and can be used interchangeably within the same design. Mixing different part numbers in a single assembly does not create compatibility issues, though maintaining consistent part numbers per assembly is recommended for traceability and documentation purposes.

Q: Which substitute part should I choose for new designs?

A: For new designs, select based on color requirement and inventory availability. The 0334824001 (black, 23,256 units) and 0334824002 (gray, 11,442 units) offer the highest stock levels and are the primary active alternatives. Both carry identical compliance certifications and performance specifications.
