SMA Plug for RG-402 Semi-Rigid — Kit Includes Contact and Insulator
The Amphenol 901-9868-RFX is an SMA plug, male pin, designed for RG-402 (.141" Semi Rigid) coaxial cable. The 50 Ohm impedance and 18 GHz frequency ceiling place it in the standard SMA performance band — full DC-18 GHz capability, not a reduced-range variant.
Cable Fit and Termination — .141" Semi-Rigid, Solder Both Ends
This plug is machined specifically for RG-402 cable — the.141" outer diameter semi-rigid coax with a solid copper outer conductor. The shield termination is solder directly to the connector body; the centre contact is a solder-cup style. The PTFE dielectric preform is included in the kit. For.085" cable (RG-405), the sibling 901-9867-RFX is the correct fit — the body bore and centre contact dimensions differ.
Mating Cycles and Field Duty — 500-Cycle Gold Interface
It is not a high-cycle production test port (those typically spec 1000+ cycles), but it will outlast a tin-plated SMA on a bench cable.
No last-time-buy or phase-out notice is on record. Lead time is confirmed per request.
Cross-Shop: 901-9867-RFX for .085" Cable
The closest functional alternative is the 901-9867-RFX, which is the same SMA plug, male pin, 50 Ohm, 18 GHz, gold body, and 500-cycle rating — but machined for RG-405 (.085" Semi Rigid) cable. The 901-9867-RFX kit includes a ferrule (4 pieces total) instead of the 3-piece kit here. If your cable is.141", this is the correct part; if.085", use the 901-9867-RFX. The 132102 and 132111 are bagged 2-piece kits (connector + contact or connector + end cap) from a different Amphenol series — functionally similar but not a direct kit match.
