B3B-EH-A

JST · Wire To Board Connector · JST_EH_B3B-EH-A_1x03_P2.50mm_Vertical

B3B-EH-A from JST, in a JST_EH_B3B-EH-A_1x03_P2.50mm_Vertical. 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 Contact 1; numbering follows the footprint.
2 2 passive Contact 2; numbering follows the footprint.
3 3 passive Contact 3; numbering follows the footprint.

CAD (KiCad official)

  • Symbol: B3B-EH-A
  • Footprint: Connector_JST:JST_EH_B3B-EH-A_1x03_P2.50mm_Vertical
  • 3D model: JST_EH_B3B-EH-A_1x03_P2.50mm_Vertical (KiCad packages3D, STEP)
  • 3D model files: b3b-eh-a-etched.step / b3b-eh-a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); b3b-eh-a.step / b3b-eh-a.glb are the bare package body.

Provenance

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

  • Datasheet: JST datasheet (3 pp, sha256 ``, retrieved 2026-11-06, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins, primary connector 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).
