Single-row, 4 circuits loaded all positions – this is a compact signal link for sensor, control, or low-pin-count telecom interfaces. The bottom or top entry style means the same part can serve as a mezzanine bottom-entry receptacle or a top-entry for a cable-to-board harness, giving layout flexibility. ## Mating Finish and Cycle Life In a telecom or automotive environment with quarterly reconnections, the gold interface provides decades of reliable contact. Phosphor bronze contact material with tin-plated solder posts – the tin finish on the termination side ensures good solder wetting during reflow, while the gold mating surface resists corrosion in the unmated state.","metaTitle":"91601-304ALF Amphenol ICC (FCI) Dubox™ 4-Pos 0.1\" Gold SMD","metaDescription":"91601-304ALF Amphenol ICC (FCI) Dubox™ board-to-board receptacle, 4 circuits, 0.100\" (2.54 mm) pitch, 30 µinch gold mating finish, 10.81 mm stack height, UL94","metaKeywords":null},"attributes":{"series":"Dubox™","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Female Socket Headers"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"Dubox™","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Pick and Place","Termination":"Solder","Applications":"Automotive, General Purpose, Industrial, Telecommunications","Contact Type":"Female Socket","Contact Shape":"Square","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Bottom or Top Entry","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Gray","Insulation Height":"0.275\\\" (6.99mm)","Ingress Protection":"-","Base Product Number":"91601","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"10.81mm","Contact Finish - Mating":"Gold","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.29000","currency":"USD"},{"qty":10,"price":"$1.09300","currency":"USD"},{"qty":100,"price":"$0.98150","currency":"USD"},{"qty":600,"price":"$0.80302","currency":"USD"},{"qty":1200,"price":"$0.71378","currency":"USD"},{"qty":1800,"price":"$0.66918","currency":"USD"},{"qty":3000,"price":"$0.64687","currency":"USD"},{"qty":6000,"price":"$0.62456","currency":"USD"},{"qty":15000,"price":"$0.57995","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8df5c1f5031c33ae8d4493619f9ad92b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 91601-304ALF and how do I get a price?","answer":"91601-304ALF is available through independent distribution.
