The brown housing is a free-hanging (in-line) socket that accepts a matching pin header — the feed-through feature allows daisy-chaining wires through the connector body. ## Last Buy — Plan Your Final Order This part is on Last Buy status, meaning the manufacturer has scheduled end of production. Any remaining stock is finite — once it clears, no more will be made. There is no official replacement or equivalent listed for the DF1-4S-2.5R24(05) in the DF1 series. If you need to maintain a harness design that uses this socket, secure your final quantity now through an RFQ. For a new design, evaluate the current Hirose DF1 series catalog for an active 4-position IDC socket at the same 2.50mm pitch. This saves assembly time compared to crimping individual terminals, but the wire insulation diameter must be within the slot's range — confirm your wire's OD against the Hirose DF1 application drawing. The feed-through feature lets you pass a continuous wire through the connector, useful for daisy-chaining in a harness. ## Mating Half and Pinout This socket mates with a 4-position pin header from the Hirose DF1 series at the same 0.098\" (2.50mm) pitch. The pinout follows the standard 1-to-4 sequential numbering on a single row. The brown housing is keyed by the polarization rib in the DF1 series — a matching header with the same keying is required for proper alignment.","metaTitle":"Hirose DF1-4S-2.5R24(05) 4-Position IDC Socket, 2.50mm Pitch","metaDescription":"Hirose DF1-4S-2.5R24(05) 4-position IDC socket, 0.098\" (2.50mm) pitch, tin-plated contacts, 24 AWG wire.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Circular Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Color":"Brown","Pitch":"0.098\\\" (2.50mm)","Series":"DF1","Package":"Bulk","Features":"Feed Through","Wire Type":"Discrete","Wire Gauge":"24 AWG","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Socket","Contact Finish":"Tin","Fastening Type":"-","Number of Rows":"1","Product Status":"Last Time Buy","lifecycle_stage":"unknown","Cable Termination":"IDC","Base Product Number":"DF1-4","Number of Positions":"4","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7400","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/DF1-4S-2.5R24(05)/alternatives.json"},"ai":{"faq":[{"question":"What is the lifecycle status of the DF1-4S-2.5R24(05)?","answer":"The DF1-4S-2.5R24(05) is on Last Buy status.
