Mated stacking height is 10.81 mm, which sets the z-height between parallel boards in a mezzanine stack. Surface-mount termination — the SMD pads are reflow-soldered to the PCB. The connector accepts bottom or top entry, meaning the mating header can approach from either side of the PCB — useful for mezzanine or board-to-board stacking where the orientation is fixed by the enclosure. ## Application Range The 30 µinch gold contacts suit environments with moderate vibration or humidity, though the push-pull retention means it is not a locking connector for high-shock installations.","metaTitle":"91601-303ALF Amphenol ICC (FCI) Dubox™ 3-Pin Female Socket","metaDescription":"Amphenol ICC (FCI) Dubox™ 91601-303ALF — 3-position female socket header, 0.100\" (2.54 mm) pitch, SMD, 30 µinch gold mating finish, 10.81 mm stack height.","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":"3","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":"$1.2400","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.24000","currency":"USD"},{"qty":10,"price":"$1.04800","currency":"USD"},{"qty":100,"price":"$0.94080","currency":"USD"},{"qty":600,"price":"$0.76973","currency":"USD"},{"qty":1200,"price":"$0.68422","currency":"USD"},{"qty":1800,"price":"$0.64145","currency":"USD"},{"qty":3000,"price":"$0.62007","currency":"USD"},{"qty":6000,"price":"$0.59869","currency":"USD"},{"qty":15000,"price":"$0.55592","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/8df5c1f5031c33ae8d4493619f9ad92b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 91601-303ALF suitable for automotive use?","answer":"The listed applications include automotive, but the push-pull fastening and lack of a secondary lock mean it is not a sealed or vibration-rated automotive connector.
