The TE Connectivity 2291392-8 is a SMB/Fakra jack with a male pin centre contact, designed for 50 Ohm RF systems up to 6 GHz. This right-angle through-hole variant orients the signal path parallel to the board — a common layout for edge-mounted RF modules or low-profile enclosures where a vertical jack would intrude on the assembly height. The connector carries a 800 V voltage rating, which is high for this connector class and points toward applications like RF power monitoring or high-voltage antenna feeds rather than low-level signal paths.
Fakra Keying and Housing
The connector is listed with a Fakra connector style and a Code H feature. In the Fakra system, the colour-coded housing and keying geometry prevent mismating between different RF circuits in a multi-connector harness — Code H corresponds to a specific key position and housing colour (violet/heather per the listing). This is the same colour-coding scheme used in automotive antenna and telematics harnesses where multiple RF feeds (GNSS, cellular, SDARS) share a common connector family. The violet housing makes the connector visually identifiable at the assembly bench and in service.
The body is zinc alloy with a tin finish, and the dielectric is glass-filled PCT. Shield termination and contact termination are both solder, meaning the cable braid and centre conductor are soldered to the connector body and pin respectively — a standard method for semi-rigid or flexible coaxial cable assemblies. The through-hole mounting provides a stronger mechanical anchor to the PCB than surface-mount alternatives, which is relevant when the cable assembly will see repeated flexing or strain.
This is a current-production part, not a legacy or phase-out line.
Comparison with 1057230-1
The 1057230-1 is a different connector type — an OSP jack, female socket, with snap-on fastening and a stainless steel body finished in gold. While both are 50 Ohm RF connectors, the 2291392-8 is an SMB/Fakra male pin jack with a locking ramp, while the 1057230-1 is an OSP style designed for RG-405 semi-rigid cable. The 2291392-8 operates to 6 GHz, whereas the 1057230-1 is rated to 22 GHz. These are not functional equivalents — the 2291392-8 is specified for Fakra-coded automotive RF harnesses, and the 1057230-1 serves a different interface standard and frequency range.
