It carries a Cat3 rating, which limits the usable frequency to 16 MHz — fine for analog telephony, 10BASE-T Ethernet, or RS-232 extension, but not for anything faster. Single-row, single-port, unshielded — this is a straightforward voice-grade jack for a BOM that needs a known footprint and a reliable latch. Cat3 is the oldest structured-cabling category still in common reference. It certifies the jack for frequencies up to 16 MHz with controlled impedance and crosstalk within the limits of TIA/EIA-568-B. For a 4p4c handset cord carrying analog voice or a 10BASE-T link, that's plenty of headroom. If the application calls for 100BASE-TX or PoE, this jack is the wrong choice — the unshielded construction and Cat3 bandwidth won't support the return loss or common-mode rejection those signals need. ## Board Lock and Through-Hole Mounting The board lock is a pair of solderable retention posts that press into plated through-holes alongside the signal pins. They take the mechanical load off the contacts when the plug is inserted or removed, which matters in a vertical jack that sees repeated cord swaps. That combination keeps the jack from lifting pads in a production rework or field-service environment. This jack mates with any standard 4p4c modular plug — the same form factor used on analog telephone handsets (RJ22), some two-line desk phones (RJ10), and slimline handsets (RJ9). The 4p4c wiring pattern means four conductors in a 4-position body; the centre two positions are normally the tip and ring for a single phone line, with the outer pair available for a second line or a data-over-voice signal. The tab direction is user-selectable, which lets the installer orient the latch release whichever way the cable routing demands.","metaTitle":"Molex 95503 0955032441 RJ22 Jack, 4p4c, Cat3, Board Lock","metaDescription":"Molex 0955032441 vertical RJ22 jack, 4p4c, Cat3 rated, gold flash contacts, board lock, -40°C to 85°C.
