Part Specification Review and Update

Thought for 2 mins 22 sec

I reviewed the part project against the existing datasheet link. Because Datasheet URL is already set, I did not replace it. The current URL points to an HLK-20M series PDF that includes HLK-20M15, so it is usable for verification.

What does not match cleanly

Table

Item	Datasheet	Current footprint evidence	Status
Overall body size	56 x 32 x 22.5 mm	Footprint outline in the asset appears about 46.9 x 27.8 mm based on outline coordinates	Mismatch flagged
Exact pin spacing	Not extractable from searchable text in the PDF	Footprint uses pad centers at approx. `(0,0)`, `(0,7.8)`, `(42.5,-7.5)`, `(42.5,15.3)`	Could not fully verify from text
Hole size / pin diameter	Datasheet text only exposed tolerance note, not clean nominal drill value	Footprint drill appears 1.0 mm	Not fully verifiable from extracted text

Summary of mismatches / issues

Table

Priority	Finding
High	Footprint body outline appears smaller than the datasheet package size (56 x 32 x 22.5 mm)
Medium	All four pins are still typed as `Unspecified`
Medium	Pin descriptions are missing
Low	Manufacturer name is abbreviated in project (`Hi-Link`) vs fuller datasheet form
Low	Several useful part properties are missing: `Part Type`, `Package or Case Code`, `Operating Voltage`, `Max Current`, `Operating Temperature`

Bottom line

Symbol/pin mapping: good
Pin count: good
Pin names/numbers: good
Pin descriptions/types: incomplete
Footprint: body outline likely incorrect and should be checked against the mechanical drawing
Datasheet URL: already present and usable, so no update was needed

If you want, I can next give you a precise property update list to apply to this part project, including suggested values for each missing field and each terminal property.
