CAD (KiCad official)

  • Symbol: ECS-080-20-4X-DU
  • Footprint: Crystal:Crystal_HC49-4H_Vertical
  • 3D model: HC-49S (KiCad packages3D, STEP)
  • 3D model files: ecs-080-20-4x-du-etched.step / ecs-080-20-4x-du-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ecs-080-20-4x-du.step / ecs-080-20-4x-du.glb are the bare package body.

Provenance

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

  • Datasheet: ECS datasheet (2 pp, sha256 ``, retrieved 2026-10-22, 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).
