MR30PW-FB Part Review

flux

I found this is a published part with 5 terminals/pads and an existing Datasheet URL pointing to a TME product page; I’m checking for an official Amass drawing/datasheet before comparing geometry.

Reviewed the MR30PW-FB part and updated the Datasheet URL to the direct TME MR30PW-FB PDF. I created the detailed report here: MR30PW-FB Part Review.
Open items:
  • Main contact holes/pads appear undersized: current 1.7 mm drill / 2.55 mm pad vs reference 1.9 mm drill / 3.0 mm pad.
  • Symbol exposes mechanical mounting holes as pins 4/5; the connector is only 3 electrical pins.
  • Pin types/descriptions are missing or unspecified.
  • I filed an internal part-quality report for the footprint/symbol issues.
Suggested next steps:
  1. Update pads 1–3 to 1.9 mm drill and 3.0 mm pad size.
  2. Mark MH1/MH2 as mechanical/non-electrical or remove them from the electrical symbol.
  3. Add pin descriptions and set pins 1–3 to passive.
  4. Optionally normalize Part Type from Connectors to Connector.

Add passive pin types and clear descriptions for the three electrical contacts.

Set contacts 1, 2, and 3 to Passive with descriptions “Electrical power contact 1/2/3.” Mechanical terminals MH1 and MH2 were left unchanged.
