The 5023520400 from Molex is a DuraClik 502352-series wire-to-board PCB header featuring a 4-circuit, single-row, 2.00mm-pitch, right-angle surface-mount configuration. The natural-color version is intended for compact and reliable wire-to-board connections in automotive, industrial, and other electronic systems.
The connector uses copper-alloy terminals with tin plating on the mating interface and a polyamide housing. It incorporates mating-part locking, mating polarization, PCB polarization, and PCB-retention features to improve assembly reliability and help prevent incorrect installation.
The 5023520400 is rated for up to 125V and 3.0A per contact. Molex describes the broader DuraClik platform as a 2.00mm-pitch wire-to-board system with secure locking and high PCB-retention force for demanding vibration and temperature environments. Actual current capability should be evaluated according to wire size, PCB design, ambient temperature, and simultaneous circuit loading.
The connector has a 6.40mm mated height and a maximum durability rating of 30 mating cycles. Both the mating-interface pitch and termination-interface pitch are 2.00mm. Its right-angle configuration enables the mating cable assembly to exit parallel to the PCB, helping optimize enclosure height and internal space.
The part is supplied in embossed tape-on-reel packaging for automated SMT assembly. Net weight is approximately 0.600g. It is an unsealed, non-stackable connector. Molex currently lists the part with a Check Availability indication on its series chart.
The exact orderable part is compliant with EU RoHS 2015/863 and EU ELV requirements. Molex currently lists the applicable REACH SVHC substances as not contained. The product is specifically identified as not low-halogen according to IEC 61249-2-21.
