Brother PT-6 vs PT-D220: a listed replacement, not an identical machine
The Brother PT-6 and PT-D220 share a useful starting point: both are keyboard-first P-touch machines for narrow labels. Brother’s 2024 replacement-model list names PT-D220 for PT-6, but “replacement” is not a promise of identical tape, power, display, package contents or feel. The PT-6 is discontinued; decide whether you are reusing a particular machine or choosing equipment for a new routine.
First separate the media
The exact PT-6 U.S. product page lists TZe tape at 3.5, 6, 9 and 12 mm. Brother’s TC10 and TC20Z1 tape pages separately name PT-6 as compatible with the 12 mm TC10 and 9 mm TC20Z1. Keep those cassette records distinct. The PT-D220 assessment supports standard TZe tapes up to 12 mm; it is not a substitute for a legacy TC cassette. If you have a drawer of refills, start with the printed code rather than width or color.
Then compare the information each listing actually provides
For PT-6, Brother confirms a QWERTY keyboard, a two-line maximum and a label-length setting. The exact product page’s “Standard Memory 15” has no unit, and the sources here do not settle its screen, print height, power arrangement, cutter or phone/computer connection. Do not fill those gaps with another model’s facts. If it is an existing PT-6, test the machine and confirm its exact media before relying on it.
The PT-D220 is a current-reference option with its own fuller profile: a 15-character one-line display, six AA batteries, a separately available AC adapter, manual cutter and a documented 9 mm maximum print height. It still stops at 12 mm TZe tape, so a buyer seeking wider output should compare another model instead. These PT-D220 details explain what is better documented about that model; they do not prove how the PT-6 is powered or cut.
Choose the one that fits your actual task
Keep the PT-6 in consideration when the exact working unit and refill are already known, you prefer QWERTY typing, and a two-line label no wider than 12 mm is enough. Choose PT-D220 when you want a currently documented household option with a known screen, power route and cut method. If you require a phone app, computer design, automatic cutting, more print height or a wider cassette, use those as must-have filters and move to a model whose exact operating plan confirms them.
A manufacturer's replacement recommendation helps narrow a comparison, but it does not make used machines interchangeable. Check the exact model marking, cassette code and included accessories on the individual offer before placing an order.
