I found the official CNC Tech product page and a searchable official series datasheet for 3020-XX-0300-00; I’m updating the part metadata with that datasheet URL now.
Key specs from datasheet: 1 A current rating, 500 VAC dielectric withstand, 20 mΩ max contact resistance, 1000 MΩ min insulation resistance, -40°C to +105°C, gold flash over nickel
Symbol check: 20 terminals present, numbered 1–20, matching the 20-position part
Footprint check: 20 SMT pads present with box-header outline; no obvious pad-count mismatch found
Flagged issues:
Pin Type is currently Unspecified on all terminals; these should ideally be Passive
Pin descriptions are not populated; for a generic connector, “Contact 1” through “Contact 20” would be clearer
Manufacturer Name was set to CNC Tech, but Flux warned it is not in the standard manufacturer option list; the value was still accepted.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal

Connector Header Surface Mount 20 position 0.100" (2.54mm)
The 3020-20-0300-00 is a shrouded rectangular male header connector manufactured by CNC Tech for board-to-cable interconnection applications. It features a dual-row, surface-mount design with a standard 2.54 mm pitch, making it suitable for signal and low-power connections in industrial, consumer, and embedded electronic systems. The connector incorporates gold-plated brass contacts for reliable electrical performance and a high-temperature nylon housing that provides excellent mechanical durability and insulation characteristics. The integrated keying slot and fully shrouded construction help ensure proper mating orientation and secure connections during assembly and operation.
