The Hirose TM23R-5A-88(50) is a Cat6-rated RJ45 jack from the TM23 series, configured as an 8p8c (8 position, 8 contact) unshielded Ethernet connector.
The Cat6 rating means this jack is built to support Ethernet signaling up to 250 MHz, covering 10/100/1000BASE-T and 10GBASE-T over short distances. The unshielded (UTP) design keeps the connector cost low and simplifies termination in non-noisy environments like office LANs, patch panels, or equipment rooms. For installations near motors, VFDs, or radio transmitters, a shielded jack would be the better call — this one relies on the twisted-pair cable alone for noise rejection.
Last Buy Status — Sourcing Decision
Hirose has placed the TM23R-5A-88(50) in Last Buy status. That means this exact order code is no longer in regular production and is available only through remaining channel inventory or surplus stock. Any open BOM line using this part should be reviewed now — either secure final quantities or qualify a replacement. No official successor order code has been published by Hirose for this specific variant, so a substitute would need to be evaluated on footprint and performance.
The tab direction is up, matching standard RJ45 keying. The 8p8c pinout follows the wiring schemes standard to Ethernet.
