CAD (KiCad official)

  • Symbol: ECS-120-32-5PXDU-TR
  • Footprint: Crystal:Crystal_SMD_HC49-SD
  • 3D model: HC-49S-SMD (KiCad packages3D, STEP)
  • 3D model files: ecs-120-32-5pxdu-tr-etched.step / ecs-120-32-5pxdu-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-120-32-5pxdu-tr.step / ecs-120-32-5pxdu-tr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: ECS datasheet (2 pp, sha256 ``, retrieved 2026-10-30, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary crystal numbering (convention), consensus off (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
