Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0334810304 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug configuration
• Number of Positions: 3-position housing
• Pitch: 0.138" (3.50mm) contact spacing
• Number of Rows: Single row arrangement
• Mounting Type: Free Hanging (In-Line) orientation
• Contact Termination: Crimp connection method
• Fastening Type: Locking Ramp mechanism
• Operating Temperature Range: -40°C ~ 150°C capability
• Series Family: MX150 33481 series

The substitute part Molex 0334813323 satisfies all mandatory matching parameters. While the contact type designation differs (Male Pin versus Male Blade) and the insulation material composition varies, both components maintain functional equivalence within the MX150 series architecture and support identical electrical and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0334813323 is the designated manufacturer-recommended substitute for the obsolete Molex 0334810304. Both components are classified under identical export control (EAR99) and tariff (HTSUS 8538.90.6000) designations, confirming regulatory equivalence.

The primary distinction between these parts is product status: the 0334810304 is obsolete, while the 0334813323 maintains active production status. This status differential ensures continued availability, supply chain support, and manufacturer technical documentation for the substitute part. Both components operate within the identical temperature range (-40°C to 150°C) and maintain equivalent mechanical and electrical interface specifications within the MX150 33481 series.

Selection of the 0334813323 substitute provides access to current inventory (975 pieces in stock) compared to the limited remaining stock of the obsolete 0334810304 (1109 pieces). For new designs, repair operations, and long-term system support, the active-status substitute part is the appropriate engineering selection.

Frequently Asked Questions (FAQ)

Q: What is the primary reason the 0334810304 requires a substitute part?
