It's the kind of field-serviceable connector you can re-pin on site with just a screwdriver — no crimp tool, no die change. The ring tongue gives a positive, vibration-resistant connection to a stud or bus bar, and the screw clamp holds the conductor without cold flow. This is the terminal you reach for when you need a reliable power connection in a panel or junction box and you want to be able to swap it out in minutes. No official second-source cross-reference is on record, but the 175036-3 and 1986548-1 are box-packaged peers in the same series if your BOM calls for bulk rather than tape-and-reel. ## Packaging Options Available in Tape & Reel (TR) for automated assembly lines or Cut Tape (CT) for prototype and low-volume work.","metaTitle":"TE Connectivity 521843-1 Power Ring Terminal, 12-16 AWG","metaDescription":"TE Connectivity 521843-1 power ring terminal, 12-16 AWG, screw termination, ROHS3 compliant.
