The TE Connectivity 228553-1 is a same-series SMB adapter configured jack to jack, with male pin center contacts on both ends. It converts one SMB jack interface to another SMB jack interface — a straight pass-through for extending or panel-mounting an SMB signal path without changing the connector family. The dielectric is PTFE, a common choice for RF connectors because of its stable dielectric constant and low loss up through several GHz. Mounting is bulkhead panel mount, secured with the included lockwasher and nut. The package ships three pieces: the connector body, the lockwasher, and the nut. No separate hardware order needed for the panel installation.
We source 228553-1 through our network of independent distributors and brokers. Because there is no direct factory replacement, the buyer should verify the adapter's fit against the existing SMB interface and confirm the center pin gender (male to male) matches the mating connectors on both ends.
Mating and Installation Notes
Both ends are SMB jacks with male center pins — snap-on coupling on both sides. The adapter mates with any standard SMB plug (female center contact). The snap-on retention is quick-connect but the 500-cycle rating means it is not intended for frequent field reconnections over the life of the equipment; it suits a semi-permanent panel feed-through or a test-point that sees occasional swaps. Bulkhead mounting: the adapter passes through the panel hole, the lockwasher goes on the inside face, and the nut tightens from the back. The nickel-plated brass body grounds to the panel through the lockwasher contact. No additional gasket or seal is provided — this is an indoor, dry-environment fit, not a weatherproof bulkhead pass-through.
