Key Parameters

Substitute Part Grouping Explanation

The Molex 0334814401 qualifies as a direct substitute for the 0334810401 based on the following critical parameters:

• Connector Type & Configuration: Both are plug housings with identical 4-position, 4.60mm pitch specifications
• Contact Interface: Male blade contact type and crimp termination are identical
• Mechanical Compatibility: Free-hanging in-line mounting and locking ramp fastening are preserved
• Physical Properties: Black color and sealed features match
• Electrical & Environmental Compliance: Both maintain ROHS3 compliance and REACH unaffected status

The primary distinction is product status: the 0334810401 is obsolete, while the 0334814401 is active production. Both parts share the same base product number (033481) and series designation (MX150 33481), confirming their functional equivalence within the MX150 connector family.
