10.4" panel, 640 × 480 — what lands in the cut-out
The GT1575-VNBD is a Mitsubishi Electric 10.4" touch screen HMI, product number GT1575-VNBD, listed under the operator-interface family. The 640 × 480 dot resolution is standard VGA on a 10.4" diagonal — sufficient for recipe screens, alarm summaries and trend pages, but tight for high-density SCADA graphics, so engineering the page count matters before commit. The display brightness is 200 cd/m² from the LCD panel with a 4-level intensity adjustment, not a continuous dimming curve. For control-room cabinets with overhead fluorescent wash or outdoor kiosks behind glass, the four discrete steps may force the integrator to land on step-3 or step-4 and accept the shorter backlight service life as a trade.
Backlight life — ~41,000 h at 25 °C
Listed backlight life is approximately 41,000 hours at an operating ambient temperature of 25 °C. At 25 °C that is roughly 4.7 years of continuous-on duty; in a panel that runs warm (40–50 °C) the figure drops per the published derating curve, so the MRO buyer should plan a replacement cycle based on the cabinet's actual thermal envelope, not the headline number. Because the lifecycle stage is mature and the backlight is the wear-out mechanism rather than the touch overlay, a stocked spare is the cheapest insurance against an unplanned panel swap on a line that cannot tolerate a screen blank event.
Mature line, quoted to order
Lifecycle stage is recorded as mature — the model is no longer the newest generation but the part remains orderable. Estimated lead time is 1–10 working days, with availability and current pricing confirmed against the RFQ. For panel builders on a fixed handover date, that 1–10 day window is workable on a single-unit order but should be re-checked at quote time on multi-unit builds because the mature-life tail often runs on broker stock rather than continuous factory runs. No official successor and no pin-compatible peer is on the ledger, so any migration to a newer GT series is a panel-cut, software-project and tag-database change rather than a drop-in — confirm against the Mitsubishi Electric GOT work2 screen-engineering notes before committing to a redesign.
