Part Metadata Review and Update

Thought for 2 mins 35 sec

Review complete.

I confirmed the part metadata against the available project data and the TL3315NF160Q datasheet workflow I followed: exact pin counts must match the datasheet, and pin numbers/functions should not be guessed . I also re-confirmed the datasheet URL already in the project against the distributor product page and kept it set to:

https://configured-product-images.s3.amazonaws.com/Datasheets/TL3315.pdf

I also normalized the project metadata so Manufacturer Name = E-Switch, Part Type = Switch, and Package or Case Code = 4.5mm x 4.5mm SMD tactile switch.

What matches

MPN: TL3315NF160Q
Manufacturer: E-Switch
Part type: tactile SPST-NO switch
Package/form factor: ~4.5 mm x 4.5 mm SMD tactile switch
Pin count: the project has 4 terminals, and the datasheet shows 4 terminals as well, which satisfies the exact pin-count check recommended for part verification
Datasheet URL: present and valid

Key specs from the datasheet / product page

Function: tactile switch, SPST-NO / momentary
Rating: 50 mA @ 15 VDC
Operating force: 160 ± 50 gf
Travel: 0.2 ± 0.1 mm
Contact resistance: 200 mΩ max
Electrical life: 500,000 cycles
Actuator height: 0.55 mm off PCB
Mounting: surface mount
Packaging: tape & reel, 5000/reel

Schematic symbol audit

Current schematic contains 4 terminal elements:

pin numbers 1, 2, 3, 4
all four currently have Pin Type = Unspecified

Assessment

Pin count matches the datasheet.
Pin numbering 1–4 is present, which aligns with the datasheet’s 4-terminal drawing.
However, the datasheet notes the terminal numbers are “for reference only”, so the current symbol should not imply unique functional differences unless those are explicitly documented.
Pin descriptions are missing on all terminals.
Pin types are incomplete: all four are Unspecified. For a switch part, that is weak metadata and should be tightened up during part cleanup. The part-sync guidance specifically calls out pin descriptions and pin types as part of a proper audit

Footprint audit

The project does include a footprint asset: TL3315NF160Q.kicad_mod
The datasheet includes a P.C. MOUNTING land pattern and package dimensions.
Metadata-level check: the footprint asset name and package description are consistent with the datasheet.
Limitation: I could not directly inspect the raw pad geometry of the .kicad_mod asset in this session, so I cannot fully verify pad sizes/spacing against the datasheet drawing yet.

Mismatches / flags

Pin Type metadata mismatch
- Project: all 4 pins = Unspecified
- Datasheet/project intent: switch terminals should have a defined electrical type rather than unspecified.
Pin descriptions missing
- No Pin Description properties are present on the terminals.
- This leaves the symbol under-documented.
Footprint not fully geometry-verified
- Asset exists and looks correctly associated.
- But I could only verify presence and package consistency, not exact pad geometry.

Bottom line

Part metadata is now consistent with the datasheet and product listing.
Datasheet URL is confirmed and set.
No pin-count mismatch found.
The main issues are incomplete terminal metadata:
- all pins still have Pin Type = Unspecified
- no pin descriptions
The footprint is present and plausibly correct, but I could not complete a pad-by-pad dimensional check in this session.

If you want, I can do the next cleanup pass and update the 4 terminals with proper pin descriptions and pin types.

Fix all mismatches

Check decoupling issues
