## CAD (KiCad official)

- Symbol: `1651-24575-BTBEYA`
- Footprint: `Crystal:Crystal_SMD_2520-4Pin_2.5x2.0mm`
- 3D model: SMD2520-4P (KiCad packages3D, STEP)
- 3D model files: `1651-24575-btbeya-etched.step` / `1651-24575-btbeya-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `1651-24575-btbeya.step` / `1651-24575-btbeya.glb` are the bare package body.
