This is what delivers the 1500 mating cycles rating, well above the 500-cycle baseline for standard tin-plated USB jacks. For a port that sees frequent reconnection — test equipment, kiosk peripherals, field-service laptops — that cycle life translates to fewer field failures from contact wear. The GXT plating also resists corrosion in environments where condensation or mild industrial fumes are present. ## Shielded Shell, UL 94 V-0 Housing The shell is Copper Alloy, fully shielded — the metal shroud wraps the contact area and grounds through the solder tabs to the PCB ground plane, containing radiated emissions from the USB 2.0 differential pair. Insulation color is black.","metaTitle":"Amphenol FCI 73725-1191BLF USB-A Receptacle, 4-Contact, 2.5A","metaDescription":"Amphenol FCI 73725-1191BLF USB-A (USB Type-A) receptacle, 4 contacts, 2.5A rating, USB 2.0, right-angle through-hole, shielded, board lock, 1500 mating cycles","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["USB, Type-C & HDMI Connectors"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Gender":"Receptacle","Series":"73725","Package":"Tube","Features":"Board Lock","Shielding":"Shielded","Termination":"Solder","Mating Cycles":"1500","Mounting Type":"Through Hole, Right Angle","Connector Type":"USB-A (USB TYPE-A)","Contact Finish":"Gold, GXT™","Product Status":"Active","Specifications":"USB 2.0","Number of Ports":"1","Voltage - Rated":"-","lifecycle_stage":"unknown","Insulation Color":"Black","Mounting Feature":"Vertical","Ingress Protection":"-","Number of Contacts":"4","Base Product Number":"73725","Current Rating (Amps)":"2.5A","Operating Temperature":"-55°C~85°C","Shell/Shielding Material":"Copper Alloy","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/35ff4baa6d32d6b45b4b02b70ed51fba.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/73725-1191BLF/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 73725-1191BLF available via RFQ confirmation?","answer":"Stock and lead time are confirmed at quote time — submit an RFQ for current availability and pricing."},{"question":"Is 73725-1191BLF RoHS compliant?","answer":"The 73725-1191BLF is listed as RoHS compliant — the GXT gold plating and copper alloy shell are lead-free, and the UL94 V-0 housing material meets the RoHS substance restrictions."},{"question":"Can 73725-1191BLF be used for USB 3.0?","answer":"No — the 73725-1191BLF is specified for USB 2.0 only.
