Part Datasheet Review and Validation

flux

Completed the part review and saved the detailed findings in Part Review: Molex 43045-0426.
Key flags: the existing Datasheet URL points to a 2-circuit drawing, while 43045-0426 is a 4-circuit Micro-Fit 3.0 header; the symbol shows six terminals even though only four are electrical contacts; pin types/descriptions are incomplete; and the footprint should be checked against the exact Molex 430450226 sales drawing for 4 signal holes + 2 retention holes.

Fix the Datasheet URL and pin metadata to match the exact Molex drawing.

I’ll update the part to reference the exact Molex 430450226 sales drawing, then set the six terminal metadata so pins 1–4 are connector contacts and pins 5–6 are retention-clip/mechanical pads.

Updated and verified the part metadata.
  • Datasheet URL now points to the exact Molex 43045-0426 / 4-circuit sales drawing: 430450226_sd.pdf
  • Pins 1–4 are marked as passive connector contacts with circuit descriptions.
  • Pins 5–6 are marked as not connected mechanical retention-clip / board-lock pads.
  • Verification confirmed the new Datasheet URL and terminal metadata are present.

Micro-Fit 3.0 Vertical Header, 3.00mm Pitch, Dual Row, 4 Circuits, with PCB Press-fit Metal Retention Clip Connector Header Through Hole 4 position 0.118" (3.00mm)
The Molex 0430450426 is a 4-position vertical PCB header belonging to the Micro-Fit 3.0 series, designed for compact and reliable power and signal wire-to-board connections. It features a 3.00 mm pitch, through-hole mounting, and a shrouded design for secure mating with compatible receptacles.
This connector is commonly used in applications requiring medium-current power delivery in a compact footprint, such as industrial equipment, automotive electronics, consumer devices, and telecommunications systems. It supports a robust locking mechanism to prevent accidental disengagement and ensures stable electrical performance in vibration-prone environments.
Key Features 4-position vertical PCB header 3.00 mm pitch (Micro-Fit 3.0 family) Through-hole solder termination Shrouded, polarized housing for correct mating Locking ramp / retention feature for secure connection Rated for medium-power applications (varies by wire gauge, up to industrial-level current use cases) Operating temperature range: -40°C to +105°C High-voltage capability (up to ~600 V rating depending on configuration) Suitable for automotive, industrial, medical, and telecom systems Typical Applications Industrial control systems Automotive electronics modules Power supply interconnects Communication equipment Embedded systems and PCB power distribution
