The MXP120 series uses interfacial seals and wire seals to keep moisture and dust out of the cavity. No wire gauge range is listed in this entry, but the 4.00 mm pitch and blade socket design typically accept 18-22 AWG — verify against the terminal datasheet before committing. ## Mating Half and Cross-Reference The mating connector for the 0349002121 receptacle is a Molex MXP120 header — typically the 34902 series (male blade pin header) in a 2-circuit, 4.00 mm pitch configuration. The header may be free-hanging or panel-mount depending on the variant. No official cross-reference or second-source exists on record; the MXP120 series is proprietary to Molex. If you need a pin-compatible alternative, the closest parametric peer within the same family would be the 2-position header from the same 34900 series, but the receptacle itself has no direct substitute outside the Molex catalog.","metaTitle":"Molex MXP120 0349002121 Receptacle, 2-Pos, 4.00mm, Sealed","metaDescription":"Molex 0349002121 MXP120 2-position receptacle, 4.00mm pitch, sealed, latch holder, -40°C to 155°C.
