It mounts through a PCB via a press-fit action — no soldering required on the connector side, which speeds assembly and allows for rework if needed. Tin-lead contacts suit applications where moderate mating cycles are expected and the operating environment is controlled. The wire gauge acceptance is 24-28 AWG stranded. On the board side, the connector uses a through-hole press-fit: the compliant pins deform slightly as they enter the plated hole, creating a gas-tight connection. This avoids thermal stress from wave soldering and simplifies rework — the connector can be pressed out and replaced. ## Position and Pitch With 9 positions loaded in a single row at 0.098\" (2.50mm) pitch, this connector is a direct match for 9-conductor 2.50mm-pitch ribbon cable. The cable pitch and board-side pitch are identical, so the footprint on the PCB mirrors the cable layout — no pitch transition. The closed-end feature means the cable stops at the back wall of the housing, ensuring consistent insertion depth across all conductors.","metaTitle":"JST 09DB-4K(LF) DB Series IDC Connector, 9 Pos, 2.50mm Pitch","metaDescription":"JST DB series 09DB-4K(LF) IDC connector, 9 positions, 0.098\" (2.50mm) pitch, through-hole press-fit, tin-lead contacts.
