The single-wall shroud guides the mating connector and protects the male pins from bending during insertion, but leaves one side open for visual alignment of pin one. The friction lock holds the mated pair against moderate vibration — enough for automotive, general purpose, medical, and telecom equipment per the application listing. ## Contact finish and current path Tin is the standard choice for cost-sensitive, low-cycle applications — it oxidises over time but the wiping action of each mate clears the surface.","metaTitle":"1718573004 Molex KK254 Header – 4 Pos, 2.54 mm, R/A","metaDescription":"1718573004 Molex KK254 single-row pin header, 4 positions, 0.100-inch pitch, right-angle through-hole, friction lock, tin-plated contacts.","metaKeywords":null},"attributes":{"series":"KK254, 171857","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Molex","Style":"Board to Board or Cable","Series":"KK254, 171857","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","Shrouding":"Shrouded - 1 Wall","Termination":"Solder","Applications":"Automotive, General Purpose, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.250\\\" (6.35mm)","Ingress Protection":"-","Base Product Number":"171857","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.100\\\" (2.54mm)","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.265\\\" (6.73mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-2","Contact Finish Thickness - Post":"60.0µin (1.52µm)","Contact Finish Thickness - Mating":"60.0µin (1.52µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.97000","currency":"USD"},{"qty":10,"price":"$0.79900","currency":"USD"},{"qty":100,"price":"$0.66600","currency":"USD"},{"qty":300,"price":"$0.66600","currency":"USD"},{"qty":1500,"price":"$0.49949","currency":"USD"},{"qty":3000,"price":"$0.48285","currency":"USD"},{"qty":7500,"price":"$0.46620","currency":"USD"},{"qty":15000,"price":"$0.43290","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8e768ac6e9f8eb962fae14d61feb9433.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1718573004 shrouded?","answer":"Yes — it has a single-wall shroud (Shrouded – 1 Wall).
