- Cross-check: symbol and footprint vs. datasheet
Symbol
- Pin count: Matches (4).
- Pin numbering: Matches datasheet mapping (1–2 one side, 3–4 the other).
- Pin naming: Current labels NO_1/NO_2 vs. COM_1/COM_2 may be misleading. The device is SPST-NO with two duplicated terminals per side; there is no “common” in the SPDT sense. Risk: wiring confusion during schematic capture or review.
Footprint
- Pad count: Matches (4).
- Pad geometry: API did not expose pad sizes/coordinates to directly validate. Recommended LSH land pattern is:
- Pad: 1.4 × 2.5 mm
- Inner spacing: 2.10 mm
- Row spacing: 4.50 mm
- Overall span: 10.00 mm Actionable risk: If the current footprint deviates from these, it may cause solderability or fit issues. Please verify pad sizes and spacings visually against these values.
Manufacturing/ordering risks
- Description mismatch risk: The project description includes “4.3mm 3.4mm”. For MPN 1301.9314.24 the datasheet states overall height 4.30 mm; “3.4 mm” appears inconsistent and could cause wrong-variant ordering or confusion.
- Solder profile: Ensure reflow-only assumption matches your assembly method; wave/hand parameters are different and not provided here.
If you want, I can update the symbol pin labels and project description text to align exactly with the datasheet, and verify or adjust the footprint to the recommended land pattern.
