SATA DOM Drop-in Fit Guide (Kontron-class & Industrial Boards)
Industrial motherboards and compact embedded PCs still use vertical SATA Disk-on-Module (DOM) for boot and OS storage when a 2.5″ bay is unavailable. This guide is for hardware engineers who must fit a China-localized (CN) industrial SATA DOM onto an existing Kontron-class or similar 7-pin footprint — without discovering height, orientation, or firmware surprises on the pilot line.
For campaign pricing and datasheet request: Industrial SATA DOM · SLC · CN. Product truth source: SATA DOM Module · Wide-temp · CN.
Who this page is for
- Sustaining / NPI engineers replacing an EOL or allocation-constrained vertical SATA DOM.
- Teams matching Kontron KSSDS-DOM-class footprints (and similar industrial DOM families).
- Designs that need SLC endurance, wide-temperature operation, and a domestic CN supply path.
If you need M.2 SATA or NVMe instead, this guide does not apply — those are different mechanical and protocol stacks.
Fit checklist (stop-ship items)
Work top-down. A “same capacity, SATA” quote is not a fit.
| Check | What to measure / read | Typical failure mode |
|---|---|---|
| Connector | 7-pin vertical SATA signal + power arrangement | No link / wrong power pin |
| Orientation | Module lean direction vs nearby capacitors / shields | Mechanical clash after solder or insert |
| Height / keep-out | DOM body height above the PCB | Hits chassis, heatsink, or mezzanine |
| Capacity | 8 / 16 / 32 GB (confirm host image size) | Image write fails or recovery partition missing |
| Flash type | SLC vs TLC marketing labels | Endurance or retention miss in 24/7 boot role |
| Temperature | Ind WT −40~85°C (and Ext where offered) | Cold boot fail in outdoor / unheated cabinets |
| Shield / EMI | Metal shield requirement on the incumbent | EMI or mechanical retention mismatch |
| Firmware behavior | Identify device, TRIM, power-loss behavior | Host BIOS / OS quirks on alternate controller |
Rule of thumb: treat vendor “compatible with KSSDS-DOM” as a starting hypothesis. Confirm pinout drawing and height on your motherboard revision.

Bring-up sequence before you scale
- Mechanical mock — verify height and lean against the production chassis, not only the open PCB.
- Link & boot — cold power cycles at the lowest claimed ambient; confirm BIOS sees the device consistently.
- Image load — write the production OS image; confirm size headroom and recovery partition behavior.
- Soak — short temperature soak if the enclosure is sealed or outdoor-rated.
- Lock the PN — capacity + temp grade + CN labeling on the BOM before bulk.

Next step
Send the incumbent PN (or a photo of the module on the board), required capacity, and temperature grade. Ask for datasheet PDF and a fit note on the same thread.
