**Starwave(思大)** · IC · HC-49S

SWXS8BCVE0-16.382600 from Starwave(思大), in a HC-49S. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Crystal terminal 1 of the 2-lead HC-49S through-hole package (0.43 ±0.125 mm lead, 4.88 ±0.25 mm lead spacing); the crystal is non-polarized and the datasheet gives no pin function. |
| 2 | 2 | passive | Crystal terminal 2 of the 2-lead HC-49S through-hole package (0.43 ±0.125 mm lead, 4.88 ±0.25 mm lead spacing); the crystal is non-polarized and the datasheet gives no pin function. |

## CAD (KiCad official)

- Symbol: `SWXS8BCVE0-16.382600`
- Footprint: `Crystal:Crystal_HC49-4H_Vertical`
- 3D model: HC-49S (KiCad packages3D, STEP)
- 3D model files: `swxs8bcve0-16-382600-etched.step` / `swxs8bcve0-16-382600-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `swxs8bcve0-16-382600.step` / `swxs8bcve0-16-382600.glb` are the bare package body.
