The right-angle through-hole orientation means the four solder tails and the two shield pins all go through the board on the same row. The shielded shell bleeds common-mode EMI to the ground plane. ## 1500 Mating Cycles and the Contact Finish GXT™ is a palladium-nickel underplate with a gold flash — harder than straight gold, so it resists fretting corrosion better in a port that sees daily plugging. ## vs 61729-1010BLF — Same Connector, Different Plating The 61729-1010BLF is the same USB 2.0 Type-B receptacle in every mechanical dimension — 4 contacts, right-angle through-hole, shielded, board lock, 1 A, 1500 cycles, UL94 V-0. The single difference is the contact finish: the -1020BLF uses gold with GXT™, while the -1010BLF uses gold without the GXT™ underplate. For a port that plugs and unplugs daily in a humid or dusty environment, the GXT™ finish on the -1020BLF adds corrosion margin. For a low-cycle internal connection, the -1010BLF saves a few cents per unit.","metaTitle":"FCI 61729-1020BLF USB-B Receptacle, USB 2.0, 4-Pos R/A","metaDescription":"FCI 61729-1020BLF USB Type-B receptacle, USB 2.0, 4 contacts, right-angle through-hole, shielded, board lock, 1 A, 1500 cycles, -55 to 85 °C, UL94 V-0, RoHS.","metaKeywords":null},"attributes":{"series":"61729","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["USB, Type-C & HDMI Connectors","USB / HDMI Cable Assemblies"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Gender":"Receptacle","Series":"61729","Package":"Tube","Features":"Board Lock","Shielding":"Shielded","Termination":"Solder","Mating Cycles":"1500","Mounting Type":"Through Hole, Right Angle","Connector Type":"USB-B (USB TYPE-B)","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":"Horizontal","Ingress Protection":"-","Number of Contacts":"4","Base Product Number":"61729","Current Rating (Amps)":"1A","Operating Temperature":"-55°C~85°C","Shell/Shielding Material":"Copper Alloy","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3700","stockQuantity":19,"priceTiers":[{"qty":1,"price":"$1.37000","currency":"USD"},{"qty":10,"price":"$1.19000","currency":"USD"},{"qty":25,"price":"$1.13920","currency":"USD"},{"qty":50,"price":"$1.11380","currency":"USD"},{"qty":100,"price":"$1.06330","currency":"USD"},{"qty":250,"price":"$0.96200","currency":"USD"},{"qty":500,"price":"$0.88604","currency":"USD"},{"qty":1000,"price":"$0.75947","currency":"USD"},{"qty":2500,"price":"$0.70884","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2b918e9899140055f7100f761f5ffcd6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between 61729-1020BLF and 61729-1010BLF?","answer":"The difference is the contact finish.
