Part Review Audit

I’ll inspect the part metadata, look for an official datasheet if needed, then compare the symbol/footprint/pins against it and update the Datasheet property if missing.
The existing Datasheet URL is already the official Omron PDF, so I’m not changing it. I’m recording the detailed cross-check as a project file now and will flag the metadata/symbol issues separately.

G3VM-201AY1 Part Review

View Document

Date: 2026-07-15 Project part: G3VM-201AY1
Review complete. The existing Datasheet URL is already the correct official Omron PDF, so I did not change it; the symbol pin numbering and footprint geometry match the datasheet.
Open items:
  • Part Type is set to Transistors, but should be relay/isolator/MOSFET relay.
  • Pin descriptions and pin types are currently sparse/unspecified.
Full details are in G3VM-201AY1 Part Review.

Pin / symbol cross-check
Datasheet terminal arrangement/internal connection for DIP4: pins 1 and 2 are the input LED; pins 3 and 4 are the bidirectional MOSFET output/load terminals. The top-view arrangement shows pins 4 and 3 on one side and pins 1 and 2 on the opposite side.

Project terminal designatorPin Number propertyIntended functionDatasheet match

K2Input LED cathode / -Matches
D_13Output/load terminalMatches
D_24Output/load terminalMatches
Symbol issue flagged: the terminal components have Pin Type: Unspecified and no explicit Pin Description populated. The terminal designators imply the correct functions, but the part metadata should ideally describe pin 1 as LED anode, pin 2 as LED cathode, and pins 3/4 as bidirectional MOSFET load terminals.

No footprint pad-location mismatch was found against the datasheet dimensions.
  1. Change project Part Type from Transistors to a relay-appropriate value such as Relay or Isolator / MOS FET Relay if available.
  2. Add explicit pin descriptions:
    • Pin 1 A: LED input anode / positive input.
    • Pin 2 K: LED input cathode / negative input.
    • Pin 3 D_1: MOSFET relay output/load terminal.
    • Pin 4 D_2: MOSFET relay output/load terminal.
  3. Consider setting terminal pin types more specifically instead of Unspecified:
    • Pins 1 and 2: LED/input/passive as supported by Flux terminal type conventions.
    • Pins 3 and 4: passive/bidirectional load terminals.
  4. Optional metadata cleanup: if standardized values are expected, set Mount to Through Hole rather than PCB.
Datasheet update status
No update was made because the part already had an official Omron datasheet URL set and it was verified as the correct datasheet for G3VM-201AY1.
