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.","metaTitle":"JST 10DB-4K(LF) DB Series IDC Connector, 10 Pos","metaDescription":"JST 10DB-4K(LF) DB series IDC connector, 10 positions, 0.098\" (2.50mm) pitch, closed end, 24-28 AWG stranded, through hole press-fit.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Wire-to-Board Connectors"],"specifications":{"Mfr":"JST Sales America Inc.","Color":"Black","Series":"DB","Package":"Bulk","Features":"Closed End","Wire Gauge":"24-28 AWG, Stranded","Cable Pitch":"0.098\\\" (2.50mm)","Row Spacing":"-","Mounting Type":"Through Hole, Press-Fit","Connector Type":"Individual Wires","Contact Finish":"Tin-Lead","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Board-Side Pitch":"0.098\\\" (2.50mm)","Cable Termination":"IDC","Base Product Number":"10DB","Number of Positions":"10","Contact Finish Thickness":"-","Number of Positions Loaded":"All"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5021","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/358752ccd8166e42767e2363344ec79a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What wire gauge is compatible with JST 10DB-4K(LF)?","answer":"The JST 10DB-4K(LF) accepts 24-28 AWG stranded wire. The IDC slots are sized for that range — use solid or ferruled wire outside that range at your own risk, as the insulation-displacement contact may not cut through reliably."},{"question":"Is the JST 10DB-4K(LF) connector closed end?","answer":"Yes, the JST 10DB-4K(LF) is a closed-end connector. The back of the housing is solid, so wires cannot push through the back during termination — this prevents shorting and keeps the harness end clean."},{"question":"What is the cable pitch of JST 10DB-4K(LF)?","answer":"The cable pitch is 0.098\" (2.50mm), which matches the board-side pitch.
