The tin body finish on the brass shell mates with the threaded coupling of a standard F-type plug. 500 mating cycles is a realistic field-service figure for a threaded RF connector — the tin-on-tin interface will wear, but the beryllium copper spring contact holds its force through that cycle count. ## NRND Lifecycle and Sourcing The 531-40078-1 carries a Not Recommended for New Design (NRND) status. That means Amphenol RF still manufactures it for existing production, but it is not intended for new BOM placements. There is no official replacement order code on record. If you are laying out a new board or harness, look at current-production 75 Ohm F-type receptacles from the same family; the 531 base series includes active variants that share the same panel cutout and cable group. ## Mounting and Environmental Range Insertion loss is rated at 0.1 dB, which is typical for a well-terminated 75 Ohm F-type at frequencies up to 1 GHz.","metaTitle":"Amphenol 531-40078-1 F-Type Receptacle, 75 Ohm, 1 GHz, NRND","metaDescription":"Amphenol 531-40078-1 F-type receptacle, 75 Ohm impedance, 1 GHz max frequency, RG-179 cable group.
