The 75 Ohm impedance targets video distribution, broadband data, and test equipment signal paths where 50 Ohm would create a mismatch — think CCTV camera feeds, cable TV headends, or baseband video routers. The body and centre contact are both brass with gold finish, and the centre contact plating is also gold — standard practice for RF connectors that need consistent contact resistance over repeated matings. ## Threaded Coupling vs Snap-On: Where This SMC Fits The 152119-75 uses threaded fastening, which distinguishes it from the snap-on SMB style of the 903-415J-51P. Both are subminiature RF connectors, but the threaded coupling on this SMC jack gives it a more vibration-resistant mate — useful when the connector is on a panel or board that sees mechanical shock. The trade-off is slightly slower mating compared to a push-on SMB, but you get a more positive lock that won't back off under cable strain.","metaTitle":"Amphenol 152119-75 SMC Jack, 75 Ohm, Through Hole, Gold","metaDescription":"Amphenol 152119-75 SMC jack, male pin, 75 Ohm impedance, through-hole solder termination, gold body and center contact.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"75Ohm","Body Finish":"Gold","Cable Group":"-","Body Material":"Brass","Housing Color":"Gold","Mating Cycles":"500","Mounting Type":"Through Hole","Connector Type":"Jack, Male Pin","Fastening Type":"Threaded","Insertion Loss":"0.3dB","Product Status":"Active","Connector Style":"SMC","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"152119","Contact Termination":"Solder","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C~165°C","Center Contact Plating":"Gold","Center Contact Material":"Brass"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/598190dd3376c6cfd21c2fb8bc241aab.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/152119-75/alternatives.json"},"ai":{"faq":[{"question":"Is 152119-75 a BNC or TNC connector?","answer":"No, the 152119-75 is an SMC (SubMiniature version C) connector, not BNC or TNC.
