0.098" Pitch IDC Connector, 10 Positions, Closed End
The JST 10DB-4K(LF) is a 10-position, single-row IDC connector from the DB series, designed for mass-terminating discrete wires to a 0.098" (2.50mm) pitch. The closed-end housing prevents wire over-insertion and protects against shorting to the board — a practical detail for harness builds where the cable is cut to length on the line. It accepts 24-28 AWG stranded wire, and the through-hole press-fit mounting eliminates soldering, which suits high-reliability or rework-friendly assemblies where a solder joint is a failure point.
Press-Fit Termination and IDC Wire Termination
Termination is IDC on the cable side — the 24-28 AWG stranded conductors are pressed into the insulation-displacement slots, one per position, in a single operation. On the board side, the through-hole press-fit pins are compliant enough to hold in plated holes without solder. That means no reflow profile to manage and no solder-joint inspection step, which is a real time-saver in a harness-to-board assembly where the connector is the last thing populated.
Closed-End Housing and Single-Row Layout
The closed-end feature means the back of the housing is solid — no open slot for wires to push through. On a 10-position single-row connector at 2.50 mm pitch, that keeps the terminated end clean and prevents a stray strand from contacting the board. The black housing is the standard DB-series colour; no keying or polarization is listed, so the mating half determines orientation.
