Product Introduction
The Molex 2035551322 is a 2-position, 2-row male pin header from the CP-6.5 203555 series, designed for board-to-cable/wire interconnects. This through-hole, right-angle header carries a current rating of 11.8 A per circuit and a voltage rating of 600VAC/DC, making it suited for power distribution in harness assemblies. The 4-wall shrouding protects the male pins during mating and handling, while the latch holder fastening type provides positive retention against vibration in industrial or automotive environments.
Key Features and Characteristics
The header is fully shrouded with a 4-wall design, which prevents bent pins and guides the mating receptacle into alignment. The right-angle orientation routes the cable parallel to the PCB, saving vertical space in tight enclosures. Solder retention features and a board guide on the housing improve placement accuracy and hold during wave soldering. The tin-plated contacts (50.0 µin on both mating and post surfaces) are rated for the full 11.8 A per circuit, though tin is best suited for applications with fewer mating cycles compared to gold. The housing is molded from UL94 V-0 rated nylon, a requirement for equipment inside enclosures requiring flame resistance.
Applications and Environments
This header is used as a wire-to-board power interconnect in harness assemblies. The -40°C to 105°C operating temperature range and the latch holder fastening make it suitable for industrial cabinets, automotive engine compartments, and outdoor telecom equipment where temperature swings and vibration are present. The UL94 V-0 housing and 600VAC/DC voltage rating align with safety standards for equipment inside controlled enclosures.
What the Ratings Mean for Fit
The 11.8 A per circuit rating is the headline number for power delivery — each pin can carry bus-level current, so this header is sized for a main DC rail or power input, not a signal line. The 600VAC/DC voltage rating provides enough creepage margin for the pitch class, but the actual working voltage should be derated per the system's pollution degree. The right-angle through-hole mounting defines the board footprint: the 0.150" (3.81 mm) post length is the solder tail dimension that determines the PCB hole depth and solder fillet geometry. The tin plating on the mating surface means this header is intended for a limited number of mating cycles — typically under 50 — making it a good fit for a permanent or semi-permanent harness connection rather than a frequent disconnect point.
