# SWXSHBCVH0-4.233600

**Starwave(思大)** · IC · HC-49S

SWXSHBCVH0-4.233600 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 a two-lead through-hole HC-49S unit (4.88±0.25 mm lead spacing, 0.43±0.125 mm lead diameter); the drawing does not mark polarity, so it is interchangeable with pin 2. |
| 2 | 2 | passive | Crystal terminal 2 of a two-lead through-hole HC-49S unit (4.88±0.25 mm lead spacing, 0.43±0.125 mm lead diameter); the drawing does not mark polarity, so it is interchangeable with pin 1. |

## CAD (KiCad official)

- Symbol: `SWXSHBCVH0-4.233600`
- Footprint: `Crystal:Crystal_HC49-4H_Vertical`
- 3D model: HC-49S (KiCad packages3D, STEP)
- 3D model files: `swxshbcvh0-4-233600-etched.step` / `swxshbcvh0-4-233600-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `swxshbcvh0-4-233600.step` / `swxshbcvh0-4-233600.glb` are the bare package body.
