It carries a male pin centre contact and uses a snap-on fastening — no threads, just a push-and-click mate. ## 20 Mating Cycles — Plan for One-Time or Low-Cycle Duty Rated for 20 mating cycles, this receptacle is not built for repeated field disconnect. The gold-on-gold contact interface (gold centre contact plating on both halves) keeps contact resistance stable across those cycles, but the snap-on retention spring will fatigue well before a threaded RF connector would. For a production BOM that needs frequent cable swaps, look at the U.FL-R-SMT-1(40) sibling with 30 cycles — still low, but a 50% margin over this part. ## 50 Ohm Impedance, 6 GHz Ceiling — The RF Path The 6 GHz max frequency covers 5 GHz WiFi and most sub-6 GHz 5G bands, but not mmWave. The SMT footprint and the snap-on interface keep the signal launch short, which helps maintain the impedance through the transition from PCB trace to coaxial cable. For a 6 GHz link, the PCB layout must match the pad pattern and ground clearance specified in the Hirose product drawing; the connector itself is rated for the band, but the launch geometry decides whether you actually see 6 GHz or hit a resonance earlier. ## Mating Half and Cable Compatibility This receptacle mates with the X.FL-PR-SMT1-2(80) plug, which carries a female socket centre contact. Both are U.FL (UMCC) interface — the same physical form factor as Hirose's U.FL series, so standard U.FL cable assemblies with a male pin receptacle will mate with this part. The snap-on retention is the same across the X.FL and U.FL lines; the difference is in the plating and cycle-life spec. If you already have U.FL cable assemblies on the shelf, this X.FL receptacle is a drop-in fit for the board side.","metaTitle":"Hirose X.FL-R-SMT-1(80) U.FL Receptacle, 50 Ohm, 6 GHz","metaDescription":"Hirose X.FL-R-SMT-1(80) X.FL series U.FL-compatible receptacle, male pin, SMT, 50 Ohm impedance, 6 GHz max frequency, 20 mating cycles, gold plating.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"X.FL","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Cable Group":"-","Body Material":"Phosphor Bronze","Housing Color":"Black","Mating Cycles":"20","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Male Pin","Fastening Type":"Snap-On","Insertion Loss":"-","Product Status":"Active","Connector Style":"U.FL (UMCC)","Frequency - Max":"6 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"X.FL","Contact Termination":"Solder","Dielectric Material":"Liquid Crystal Polymer (LCP)","Operating Temperature":"-40°C ~ 90°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy X.FL-R-SMT-1(80) available via RFQ confirmation?","answer":"Availability is confirmed at quote time — submit an RFQ for current pricing and lead time."},{"question":"Is X.FL-R-SMT-1(80) compatible with standard X.FL cables?","answer":"Yes, this receptacle mates with the X.FL-PR-SMT1-2(80) plug, and it uses the same U.FL (UMCC) interface as standard U.FL cable assemblies.
