Compatibility and head families¶
Use the exact handle model and replacement-head listing. A common brand, T-series name or charging method does not establish a shared mechanical interface.
The handle pages and replacement-head pages record individual compatibility claims with their sources and provenance. A documented fit claim is separate from a measured interface baseline.
Model codes¶
Xiaomi's published engineering codes distinguish handles whose product names can look similar. These examples are manufacturer identifiers, not a claim that the aftermarket uses every code equally widely.
| Handle | Manufacturer code | Source |
|---|---|---|
| T500 | MES601 |
Xiaomi specifications |
| T302 | MES608 |
Xiaomi specifications |
| T501 | MES607 |
Xiaomi specifications |
| T700 | MES604 |
Xiaomi specifications |
| Oscillation | MES609 |
Xiaomi specifications |
| Oscillation Pro | MES610 |
Xiaomi specifications |
| Mijia Smart Servo-oscillation Pro | MES613 |
Xiaomi specifications |
Do not treat T700 as MES606. The T200 reference records MES606 separately, with its supporting evidence.
Compatibility boundaries¶
Xiaomi explicitly states that Oscillation Pro replacement heads are not compatible with T300, T500, T501 or T302. A seller listing that combines those names does not override that exclusion. See Xiaomi's Oscillation Pro FAQ, product introduction question 12.
Compatibility is directional and part-specific. A named replacement fitting two handles does not establish that every head sold for one handle fits the other. The graph records the supported replacement-to-handle claim and a matching lookup from the handle page.
Measured baselines¶
The Xiaomi pilot is the active measurement programme. The source review does not establish a new measured baseline, retention-force result or socket tolerance.
Public baseline names use the dated pattern:
OpenConsumables Toothbrush Head Interface: T-Series Profile, 2026-Qn Baseline
A profile is the project's measured compatibility target for a defined sample group. It is not an official manufacturer standard or a commitment to maintain a living specification.
Standards context¶
ISO 20127:2025 is the published third edition covering physical properties and test methods for powered toothbrushes. The previous 2020 edition is withdrawn. This is product-test context; it does not verify the device-to-head fit claims in this archive.
China's official catalog lists GB/T 40362-2021 as current, with implementation from 1 March 2022. The catalog does not expose the full text. Clause-specific retention thresholds need the applicable standard text and a disclosed test method before they can support a measurement claim.
