Part review summary
I checked the current part project against the existing datasheet URL in the project, so I did not need to search the web or update the datasheet property.

Metadata audit

FieldIn projectDatasheet / source checkStatus
Manufacturer Part NumberBM23PF0.8-10DP-0.35V(51)Matches Hirose catalog entry✅ Match

Key specs from the datasheet

SpecValue

Symbol cross-check

CheckResult
Terminal count14 terminals present
Expected from datasheet10 contacts + 4 mechanical pads = 14 total
Numbering style1-10 plus MP1-MP4 is consistent with the datasheet structure
Per-pin descriptionsDatasheet does not provide named signal descriptions for each contact, only numbered contacts plus power-vs-signal classification
Current pin metadataAll terminals currently have Pin Type = Unspecified
Symbol findings
  • The terminal count is correct.
  • The presence of MP1-MP4 is consistent with the datasheet's 4 mechanical hold-down / guide pads.
  • The symbol is structurally correct, but the pin metadata is incomplete:
    • Contacts 1 and 10 should be identified as power contacts
    • Contacts 2-9 should be identified as signal contacts
    • MP1-MP4 are mechanical tabs, not normal signal contacts

Footprint cross-check

CheckResult
Pad count in layout14 pads
Expected pad count14 pads
Mechanical pad presencePresent
Recommended PCB layout existenceDatasheet provides one for this exact variant
Footprint findings
  • The footprint pad count matches the datasheet.
  • The inclusion of 4 extra mechanical pads also matches the datasheet.
  • I could confirm the count and structure, but the layout tool output here did not expose pad dimensions/coordinates, so I could not fully verify exact pad geometry, spacing, or land sizes against the recommended PCB layout drawing from the datasheet.

Pin-description cross-check

ItemResult
Named per-pin functions in datasheetNot provided
Can current terminal labels be verified against names?No, because the datasheet only gives numbering/classification, not signal names
Can power-vs-signal grouping be verified?Yes

Mismatches / issues to flag

IssueSeverityNotes
Package or Case Code = TOHighThis is incorrect for this connector
All terminal Pin Type values are UnspecifiedMediumMetadata is incomplete
No short pin descriptions on terminalsLowDatasheet does not give full signal names, but power/signal/mechanical descriptions can still be added
Exact footprint geometry not fully verifiedMediumPad count matches, but dimensional verification needs pad geometry data

Recommended corrections

Field / areaRecommended value
Package or Case CodeSomething like BM23PF 10P Header, 0.35 mm pitch, 0.8 mm stack height
Pin Type for contacts 1 and 10Mark as power-related
Pin Type for contacts 2-9Mark as signal/passive
Pin description for MP padsMark as mechanical hold-down / guide tab
Bottom line
  • MPN, manufacturer, mount, and overall description are fine
  • Package field is wrong
  • Symbol terminal count matches the datasheet
  • Footprint pad count matches the datasheet
  • Pin metadata is incomplete
  • No datasheet URL action was needed because one is already set
If you want, I can next update the incorrect package field and fill in the terminal pin types/descriptions for this part.
Fix all mismatches
Check footprints too
