The TE Connectivity 1658260-2 is a non-gendered coaxial compression stacker — a surface-mount RF interconnect that mates two boards or a board-to-cable assembly without a traditional plug-and-jack pair. The gold-plated brass body and phosphor bronze centre contact with gold plating suit repeated mating in controlled-impedance signal paths.
The 50 Ohm impedance and 6 GHz frequency ceiling define the usable RF bandwidth — this connector is sized for high-frequency signal paths up into the mid-microwave range, not for DC power or low-speed digital. The 25 mating cycles are low — this is a board-level interconnect meant for occasional rework or test access, not a field-serviceable cable connector that sees daily connect-disconnect.
Deployment Context
The compression-style contact termination mates without soldering the centre pin — the stacker compresses onto a pad or mating half, which suits automated board-to-board assembly where a solderless RF interconnect is preferred.
No official replacement order code is on record. If a pin-compatible alternative is needed, the board footprint and impedance (50 Ohm, SMT, compression-style) define the search criteria; no direct TE cross-reference is published.
