Part Review and Datasheet Verification

Worked for 7 mins 35 sec

Review complete. The project already had a Datasheet URL, so I did not update it; I documented the full cross-check in HR911130A Part Review.

Key flags:

Project description says 10/100Base-T, but the datasheet identifies HR911130A as 100/1000Base-T / IEEE 802.3ab.
Schematic LED pins 13 and 14 are polarity-swapped vs. datasheet: pin 13 should be Yellow cathode, pin 14 should be Yellow anode.
Footprint hole pattern matches the datasheet, but the footprint has 18 physical holes/pads while the symbol exposes 14 electrical terminals; shield/mechanical handling should be intentional.

Suggested next steps:

Fix the pin 13/14 LED labels/polarity.
Rename LED terminals to color-specific names.
Update the part description to 100/1000Base-T.
Decide whether shield tabs 15/16 should be schematic terminals.

Fix the LED pin labels, update the description, document shield tabs, then run a part review again.

I’ll update the LED terminal labels/polarity naming, revise the project description/spec wording, document shield-tab handling, then re-run the part review checks.

Done. I updated the description to 100/1000Base-T / IEEE 802.3ab, documented shield pads 15/16 and NPTH holes 17/18, and re-ran the review in HR911130A Part Review.

Open item:

Pin 14’s Pin Description is now correct as Yellow LED anode, but its visible terminal label still shows GREEN_CATHODE::18b70343 due to duplicate-label targeting behavior in the schematic editor.

Suggested next steps:

Manually rename pin 14’s visible label to YELLOW_ANODE in the symbol editor.
Optionally expose shield tabs 15/16 as schematic terminals if users need chassis/shield connectivity.

HR911130A Part Review

Update status

This review was re-run after applying the requested fixes:

Project description updated to 100/1000Base-T / IEEE 802.3ab wording.
Shield/mechanical footprint pads documented in the project description and this review.
LED pin descriptions updated to datasheet-correct color/polarity descriptions.
Visible LED labels are corrected for pins 11, 12, and 13. Pin 14 still carries the visible base label GREEN_CATHODE::18b70343 due to duplicate-label targeting behavior, but its Pin Description and Pin Group correctly identify it as Yellow LED anode.

Footprint cross-check

The footprint asset HR911130A.kicad_mod contains:

Pads 1-10: through-hole circular, drill 0.889 mm, size 1.397 mm.
Pads 11-14: through-hole circular LED pins, drill 1.016 mm, size 1.524 mm.
Pads 15-16: through-hole circular shield/mechanical tabs, drill 1.6256 mm, size 2.1336 mm.
Pads 17-18: NPTH locating holes, drill/size 3.2512 mm.

Datasheet recommended PCB pattern specifies 10 x 0.89 mm signal holes, 4 x 1.02 mm LED holes, 2 x 1.63 mm shield/mechanical holes, and 2 x 3.25 mm locating holes. The footprint matches these values within rounding.

Shield-tab documentation

Pads 15 and 16 are treated as physical shield/mechanical plated through-hole tabs in the footprint. Pads 17 and 18 are non-plated locating holes. The current schematic exposes only pins 1-14 as electrical terminals; shield tabs 15/16 are intentionally documented rather than exposed as schematic terminals. If a downstream design needs explicit chassis/shield connectivity, add schematic terminals for pads 15 and 16 or otherwise document the intended shield connection policy in the target design.

Final review result

Part identity: Pass
Project description: Pass
Pinout: Pass by pin number and Pin Description; visible label mismatch remains only on pin 14
Footprint: Pass
Shield/mechanical tabs: Documented
