Coaxial Switch for RF Signal Routing
The Hirose MS-162(01) is a coaxial switch receptacle from the MS-162 series, designed as a 50 Ohm impedance signal path component for RF applications. It presents a female socket interface with a 4mm plug diameter, using a snap-on fastening mechanism for quick connect-disconnect cycles.
Sourcing Reality — Obsolete Status
If you need a drop-in alternative, the base product number MS-162 suggests there may be other variants in the series — but without an L* successor entry, we cannot name a specific substitute. A cross-reference search against the MS-162 series may yield a functional equivalent, but pin-to-pin compatibility must be verified against the original PCB footprint and mating interface.
RF Performance and Mechanical Endurance
The 10 GHz frequency ceiling covers common wireless bands (Wi-Fi, cellular, ISM) and many instrumentation signals up to X-band lower edge. The 0.7 dB insertion loss figure is a single-point spec; actual loss varies with frequency and mating condition. The gold-on-gold contact interface (gold center contact plating, gold body finish) resists corrosion and maintains consistent RF performance across those cycles.
Surface mount (SMT) mounting with solder termination on both the shield and center contact. The shield termination is listed as solder, and the contact termination is also solder — this is a reflow-compatible part. The bulk package means parts are shipped in tubes or trays, not tape-and-reel, so plan for manual or tube-fed placement rather than auto-reel feeding.
