INA219AIDCNR Part Review
Date: 2026-07-22 Reviewed the available Flux part information for INA219AIDCNR against the Texas Instruments INA219 datasheet and TI product...
Completed the INA219AIDCNR part review and created the detailed report: INA219AIDCNR Part Review.
Open items:
- Pin names/numbers match the TI datasheet, but all pin types/descriptions are missing or
Unspecified. - Package is broadly correct, but
SOT-23should ideally be more specific:SOT-23-8 / DCN. - Datasheet URL was already populated, so I did not overwrite it; the official TI URL found is
https://www.ti.com/lit/gpn/ina219.
Suggested next steps:
- Update pin type and pin description metadata.
- Change package metadata to
SOT-23-8 / DCN. - Replace the uploaded datasheet URL with the official TI URL if you want canonical sourcing.

Footprint Cross-Check
Current footprint asset:
SOP65P280X145-8N.kicad_mod.Observed footprint data:
- 8 SMD rectangular pads.
- Pad pitch: 0.65 mm.
- Pad size: 0.45 mm × 1.075 mm.
- Pad row spacing: about 2.676 mm center-to-center from x = ±1.338 mm.
- Fab body outline: 1.6 mm × 2.9 mm.
- Silk and fab outline include a pin-1/chamfer marker.
- 3D model asset:
INA219AIDCNR.stp.
TI DCN / SOT-23-8 package and land pattern data extracted:
- Body length: 2.80–3.00 mm.
- Body width: 1.45–1.75 mm.
- Overall width: 2.60–3.00 mm.
- Height: 0.90–1.45 mm.
- Lead pitch: 0.65 mm.
- Recommended land pattern pad geometry: 0.45 mm typ × 1.1 mm typ.
- Recommended row spacing: 2.6 mm.
Result: footprint geometry is consistent with TI DCN / SOT-23-8 land pattern. The footprint filename uses
SOP... rather than SOT-23-8 or DCN; this is a naming/semantic issue, not a geometry mismatch based on the dimensions inspected.Mismatches / Issues Flagged
- Pin metadata is incomplete. All schematic terminal Pin Type values are
Unspecified, and no Pin Description properties are present. Pin names and pin numbers match the datasheet. - Package property is too generic.
SOT-23is broadly correct, but TI identifies this exact orderable package asSOT-23 (DCN), 8 pins. PreferSOT-23-8 (DCN)orDCNif the property can be made more specific. - Datasheet URL is populated but not the canonical TI URL. The existing uploaded PDF is usable, but the official TI URL is
https://www.ti.com/lit/gpn/ina219; prefer that for traceability if editable. - Description is accurate but packaging-centric. It identifies current/power monitor and SOT-23-8 full reel. A cleaner reusable part description would be:
INA219 26-V, 12-bit I2C/SMBus current, voltage, and power monitor, DCN SOT-23-8; INA219AIDCNR tape-and-reel orderable. - Footprint name is semantically imprecise.
SOP65P280X145-8Nappears to encode the correct pitch/body/pin count, but the device is officially DCN / SOT-23-8.
Overall Verdict
The INA219AIDCNR part is fundamentally correct for pinout and footprint geometry. The main quality gaps are metadata: add pin types/descriptions, make the package code more exact, and prefer the official TI datasheet URL if direct part-property editing is available.
