JST PH, XH, EH and GH connectors, 2–8 pin — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/jst-connectors/ (CC BY 4.0) Basis: KiCad 3D models of JST datasheet geometry; pitch PH 2.0 mm, XH 2.5 mm, EH 2.5 mm, GH 1.25 mm Catalog version: 2026-10-20 Sizes: see table below - XH (2.5 mm pitch, the white 'balance lead' connector): header 2 pin is about 7.4 × 5.75 × 7 mm; each extra pin adds 2.5 mm. PH (2.0 mm): 2-pin header about 5.9 × 4.5 × 6 mm, +2.0 mm per pin. - EH is 2.5 mm pitch like XH but lower (5.4 mm) and narrower; GH is the 1.25 mm pitch latching micro connector on drones and Pi cameras. - Leave 8 mm above a vertical XH header for the mating plug and finger room; 10 mm for the wire exit on horizontal headers. - Bounding boxes in the table are computed from the STEP files; they include the pins below the board. part bbox_l_mm bbox_w_mm bbox_h_mm eh-b2b-eh-a-1x02-p2.50mm-vertical 9.2 7.5 3.8 eh-b3b-eh-a-1x03-p2.50mm-vertical 10.0 9.2 3.8 eh-b4b-eh-a-1x04-p2.50mm-vertical 12.5 9.2 3.8 eh-b5b-eh-a-1x05-p2.50mm-vertical 15.0 9.2 3.8 eh-b6b-eh-a-1x06-p2.50mm-vertical 17.5 9.2 3.8 eh-b7b-eh-a-1x07-p2.50mm-vertical 20.0 9.2 3.8 eh-b8b-eh-a-1x08-p2.50mm-vertical 22.5 9.2 3.8 gh-bm02b-ghs-tbt-1x02-1mp-p1.25mm-vertical 5.8 5.0 4.2 gh-bm03b-ghs-tbt-1x03-1mp-p1.25mm-vertical 7.0 5.0 4.2 gh-bm04b-ghs-tbt-1x04-1mp-p1.25mm-vertical 8.2 5.0 4.2 gh-bm05b-ghs-tbt-1x05-1mp-p1.25mm-vertical 9.5 5.0 4.2 gh-bm06b-ghs-tbt-1x06-1mp-p1.25mm-vertical 10.8 5.0 4.2 ph-b2b-ph-k-1x02-p2.00mm-vertical 9.4 5.9 4.6 ph-b3b-ph-k-1x03-p2.00mm-vertical 9.4 7.9 4.6 ph-b4b-ph-k-1x04-p2.00mm-vertical 9.9 9.4 4.6 ph-b5b-ph-k-1x05-p2.00mm-vertical 11.9 9.4 4.6 ph-b6b-ph-k-1x06-p2.00mm-vertical 13.9 9.4 4.6 ph-b7b-ph-k-1x07-p2.00mm-vertical 15.9 9.4 4.6 ph-b8b-ph-k-1x08-p2.00mm-vertical 17.9 9.4 4.6 ph-s2b-ph-k-1x02-p2.00mm-horizontal 8.3 7.6 5.9 ph-s3b-ph-k-1x03-p2.00mm-horizontal 8.3 7.9 7.6 ph-s4b-ph-k-1x04-p2.00mm-horizontal 9.9 8.3 7.6 ph-s5b-ph-k-1x05-p2.00mm-horizontal 11.9 8.3 7.6 ph-s6b-ph-k-1x06-p2.00mm-horizontal 13.9 8.3 7.6 xh-b2b-xh-a-1x02-p2.50mm-vertical 10.4 7.4 5.8 xh-b3b-xh-a-1x03-p2.50mm-vertical 10.4 9.9 5.8 xh-b4b-xh-a-1x04-p2.50mm-vertical 12.4 10.4 5.8 xh-b5b-xh-a-1x05-p2.50mm-vertical 14.9 10.4 5.8 xh-b6b-xh-a-1x06-p2.50mm-vertical 17.4 10.4 5.8 xh-b7b-xh-a-1x07-p2.50mm-vertical 19.9 10.4 5.8 xh-b8b-xh-a-1x08-p2.50mm-vertical 22.4 10.4 5.8 xh-s2b-xh-a-1-1x02-p2.50mm-horizontal 11.5 9.5 7.4 xh-s2b-xh-a-1x02-p2.50mm-horizontal 11.5 9.5 7.4 xh-s3b-xh-a-1-1x03-p2.50mm-horizontal 11.5 9.9 9.5 xh-s3b-xh-a-1x03-p2.50mm-horizontal 11.5 9.9 9.5 xh-s4b-xh-a-1-1x04-p2.50mm-horizontal 12.4 11.5 9.5 xh-s4b-xh-a-1x04-p2.50mm-horizontal 12.4 11.5 9.5 xh-s5b-xh-a-1-1x05-p2.50mm-horizontal 14.9 11.5 9.5 xh-s5b-xh-a-1x05-p2.50mm-horizontal 14.9 11.5 9.5 xh-s6b-xh-a-1-1x06-p2.50mm-horizontal 17.4 11.5 9.5 xh-s6b-xh-a-1x06-p2.50mm-horizontal 17.4 11.5 9.5 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - KiCad: kicad-packages3D library (origin of these files) — STEP, WRL — CC BY-SA 4.0 with KiCad exception — https://gitlab.com/kicad/libraries/kicad-packages3D Free files (CC BY-SA 4.0 (KiCad library license, with the KiCad exception), KiCad library contributors; STEP + STL, 41 parts): https://xemstudio.com/files/kicad/jst-connectors/index.json API: https://xemstudio.com/api/geometry?object=jst-connectors
