A Component From the TCQA Family, Not the Full Board
Unlike the other items in the DS200TCQA family — which are the entire analog I/O board, installed in position 2 of the Mark V's <R>, <S>, and <T> cores — the DS200TCQAF1B is a 28-pin integrated circuit that stores software/firmware used by that family of boards. If you came here looking for the entire TCQA board, the right product is a DS200TCQAG1A, G1B, or G2B reference; if you specifically need the memory component, this is the right item.
Why This Matters When Buying
Not every component on a Mark V board is separately user-replaceable — but some memory circuits (such as the EPROMs identified at positions U6/U7 on some boards in the family) can be moved or swapped between boards in specific maintenance situations. From the technical sources we consulted, we don't have independent confirmation of this component's exact pinout or precise position on the parent board — so we won't speculate on that here. What's safe to recommend: confirm with our team, in your quote request, whether this component is compatible with the exact revision of your TCQA board before any intervention.
Handling Precautions
Memory components like this one are sensitive to electrostatic discharge. Use a properly grounded anti-static wrist strap throughout handling, avoid touching the pins directly, and keep the component in its anti-static packaging until the moment of installation.
Diagnose Before You Buy
Before assuming this specific component is the cause of a TCQA fault, it's worth ruling out the more common causes of similar symptoms: field sensors (LVDT, thermocouple), the associated wiring and terminal boards, and the TCQA board as a whole. An isolated memory component is rarely the first suspect in a field diagnosis.
