AYF532435 Part Review

Completed the AYF532435 review and created the detailed report here: AYF532435 Part Review.
Open items:
- Datasheet URL was already set, so I did not overwrite it; I flagged that it points to an uploaded copy rather than the official Panasonic URL.
- Footprint geometry looks consistent with the datasheet.
- Main mismatches are metadata quality issues: missing pin descriptions/types and MP_1/MP_2 should be clearly marked as mechanical/holding pads.
Suggested next steps:
- Update terminal descriptions for pins 1–24 and MP_1/MP_2.
- Optionally replace the Datasheet URL with Panasonic’s official PDF URL.
- Normalize manufacturer name to “Panasonic Industry Co., Ltd.” if you want stricter sourcing metadata.

AYF532435 Part Review
Scope
Reviewed available part metadata, project properties, schematic terminals, footprint data, and datasheet-derived specifications for Panasonic AYF532435.
Datasheet status
- Existing project Datasheet URL:
https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/454588632f674526dcb94fe4bd76d94c0c06b9305543004169d65f739e862fc6.pdf - Datasheet update performed: No. A Datasheet URL was already set, matching the user's conditional instruction.
- Official Panasonic reference found for traceability:
https://industry.panasonic.com/ac/e_download/control/connector/fpc-ffc/catalog/con_eng_y5bw.pdf - Official product page found:
https://industry.panasonic.com/global/en/products/control/connector/fpc-ffc/number/ayf532435

Symbol and pin review
Datasheet pin assignment identifies pins 1 through 24 as FPC/FFC signal contacts: Contact 1 through Contact 24.
Project symbol state:
- 26 terminal entries exist.
- Terminals 1 through 24 map to pin numbers 1 through 24.
- Terminals
MP_1andMP_2map to pin numbers 25 and 26. - Pin Type is
Unspecifiedfor every terminal. - No pin names, pin descriptions, or sections/groups are populated in the inspected terminal properties.
Assessment:
- Pin count for signal contacts matches: 24 contacts are present.
- The two additional pads are consistent with mechanical/soldering/holding metal pads, but the schematic currently exposes them as terminal pins numbered 25 and 26. This is acceptable only if the part model intentionally exposes solder tabs as connectable pads. Otherwise, they should be marked/described as mechanical/holding contacts and not treated as normal signal pins.
- Main metadata gap: missing pin descriptions. Recommended descriptions are
FPC/FFC signal contactfor pins 1-24 andsoldering/holding metal padfor MP_1/MP_2.
Footprint review
Footprint source inspected from inline KiCad module
AYF532435.kicad_mod.Contact pads 1-24
- Pads 1-24 are SMD rectangular pads.
- Pad size: 0.300 mm x 0.800 mm.
- Pitch: 0.500 mm.
- X positions run from -5.750 mm to +5.750 mm, producing an 11.50 mm first-to-last contact pitch span.
- These values match the datasheet's recommended PC board pattern values of 0.30 ±0.05 mm, 0.80 ±0.05 mm, and 0.50 ±0.05 mm pitch.
Mechanical / metal pads
- Pads 25 and 26 are SMD rectangular pads at x = ±6.750 mm.
- Pad size: 0.400 mm x 0.800 mm.
- This matches the datasheet's recommended metal/holding pad values of 0.40 ±0.05 mm and 0.80 ±0.05 mm.
Body / outline
- Footprint fab outline is approximately 14.0 mm x 3.2 mm, consistent with 24-pin body dimension A = 14.00 mm and connector depth 3.20 mm.
- Courtyard is larger than the body, which is expected.
- STEP model is present.
Mismatches / issues to flag
- Pin descriptions missing: Terminals have no populated pin names/descriptions; all are
Unspecified. - Mechanical pads exposed as numbered schematic terminals:
MP_1andMP_2are assigned pin numbers 25 and 26. The datasheet has 24 signal contacts plus soldering/holding terminals, not 26 user signal positions. These should be clearly described as mechanical/holding pads or excluded from normal signal use. - Datasheet URL is not the official Panasonic URL: The existing Datasheet URL points to an uploaded copy. It appears to contain the Panasonic datasheet, and no update was required by the user's conditional instruction, but using the official Panasonic URL would improve traceability.
- Manufacturer naming variation: Project says
Panasonic; official source saysPanasonic Industry Co., Ltd.. This is not electrically significant but could be normalized.
Overall conclusion
The MPN, 24-position count, 0.5 mm pitch, body dimensions, pad count, and footprint land pattern are consistent with Panasonic AYF532435. The main cleanup items are metadata quality issues rather than footprint geometry errors: add pin descriptions/types and clarify MP_1/MP_2 as mechanical/holding pads.
