Part Datasheet Audit

flux

I’ll audit the part metadata, locate the official datasheet if needed, update its Datasheet property, then compare the symbol, footprint, and pin descriptions against the manufacturer documentation.

flux

I’m reading the current metadata and geometry first; the datasheet lookup will be based on the exact MPN and manufacturer found in the part.

Audit of published part BLOCK VB 1,0/1/6 against the official manufacturer product page and English datasheet. Project/part: VB1,0_1_6

flux

Audit complete. The existing Datasheet URL is already an official BLOCK page, so it was retained. The main mismatch is critical: the symbol and footprint use pins 1–4, while the datasheet specifies primary 1–5 and secondary 7–9; pin descriptions/types and package metadata are also incomplete.
Full findings: Part Audit Report. I also filed an internal part-quality report for the incorrect pin numbering.

Datasheet connection assignment
The official datasheet identifies:
  • Primary 230 VAC: pins 1 and 5
  • Secondary 6 VAC: pins 7 and 9
Symbol review
The part contains four terminal objects positioned as two primary terminals on the left and two secondary terminals on the right. This functional separation is correct.
Mismatches
  1. Terminal numbering is incorrect. The current symbol uses pin numbers 1, 2, 3, 4. The datasheet uses 1, 5, 7, 9.
  2. Pin descriptions are absent. Terminals should explicitly identify primary and secondary functions and ratings.
  3. Pin types are Unspecified. For a passive transformer winding, Passive is the appropriate electrical pin type if available in the part editor.
  4. Current terminal designators (PRI_1, PRI_2, SEC_1, SEC_2) communicate function, but their stored Pin Number fields do not match the physical package.

Table

Current terminalCurrent pin numberRecommended physical pin numberRecommended description
PRI_111Primary winding, 230 VAC
PRI_225Primary winding, 230 VAC
SEC_137Secondary winding, 6 VAC, 166 mA
SEC_249Secondary winding, 6 VAC, 166 mA
The secondary orientation should be checked against the actual datasheet drawing before treating SEC_1 versus SEC_2 as polarity/dot information; the transformer is specified as AC and no polarity requirement was found in the extracted text.
Footprint review
The footprint asset defines four through-hole pads at:
  • pad 1: (0, 0) mm
  • pad 2: (0, 20) mm
  • pad 3: (20, 15) mm
  • pad 4: (20, 5) mm
This gives a 20 mm primary spacing, 10 mm secondary spacing, and 20 mm separation between winding columns. The pattern is mechanically plausible for the EI 30/10,5 package and is consistent with the datasheet's four physical leads, but the pad numbers must be changed to 1, 5, 7, 9 to match the manufacturer connection diagram.
Footprint geometry observations
  • Pads are defined as 1.5 mm circular plated through-holes with 1.0 mm drills in the KiCad footprint source.
  • The component fabrication outline is approximately 27.3 × 32.3 mm; the official maximum package dimensions are 27.8 × 32.8 mm in plan view. The outline is therefore 0.5 mm smaller in each plan dimension. This may represent a nominal-body drawing convention, but it should be confirmed visually against the manufacturer's dimensional drawing.
  • The courtyard is approximately 30.05 × 34.3 mm, extending beyond the stated body size and providing assembly clearance.
  • The exact manufacturer lead diameter/tolerance was not recoverable from searchable datasheet text, so the 1.0 mm drill cannot be fully validated from the available OCR alone.
  • The embedded footprint source correctly expresses 1.5 mm pads and 1.0 mm drills. Some computed layout readback values appeared scaled to metres despite being labeled mm; this appears to be a display/readback unit issue rather than footprint-source geometry.
Overall disposition
Not fully datasheet-conformant. The electrical ratings, manufacturer, MPN, mount style, functional primary/secondary arrangement, pin count, and general physical pattern are consistent. The critical issue is that both the symbol and footprint use sequential pin numbers 1–4 instead of the manufacturer's physical pin numbers 1, 5, 7, and 9. Pin descriptions and passive pin typing are also missing, and the Package property is not populated.
  1. Renumber symbol terminals and footprint pads to 1, 5, 7, and 9 while preserving their physical positions.
  2. Add terminal descriptions for primary 230 VAC and secondary 6 VAC / 166 mA.
  3. Change terminal electrical types from Unspecified to Passive if supported.
  4. Add a package/case identifier such as EI 30/10,5, PCB THT, 32.8 × 22.3 × 27.8 mm.
  5. Retain the existing official product-page Datasheet URL; optionally store the direct official PDF in a machine-datasheet field if desired.
  6. Visually verify the dimensional drawing for lead diameter and body datum before final release.
