Do similar model codes mean the same head fits?
No. A shared model stem, matching battery capacity or similar product dimensions do not establish brush-head compatibility. Obtain the supplier's exact head reference and confirm each proposed head-and-handle pairing against the selected revisions and instructions. The catalog records below identify candidates; they do not confirm interchangeable heads or replacement-head availability.
Start with separately ordered model records
The oral care catalog contains one oral irrigator and six toothbrush records. Irrigator nozzles belong to a separate accessory review. For toothbrushes, keep both the supplier model and catalog ID on the sample request, even where published specifications match.
| Model and catalog source | Published configuration | Product and unit-box dimensions |
|---|---|---|
| YW-10 / P338 Physical page 48 | Five operating modes; 400 mAh battery; DC 3.7 V; 1 W. | Product: 21.6 × 2.8 × 2.8 cm. Box: 18.8 × 10.1 × 3.3 cm. |
| YW-10A / P339 Physical page 49 | Five operating modes; 400 mAh battery; DC 3.7 V; 1 W. Separate model identity. | Product: 21.6 × 2.8 × 2.8 cm. Box: 18.8 × 10.1 × 3.3 cm. |
| YW-1 / P340 Physical page 50 | Five operating modes; 800 mAh battery; sonic motor; DC 3.7 V; 1.5 W. | Product: 24.8 × 2.8 × 2.8 cm. Box: 18.8 × 10.1 × 3.3 cm. |
Source: Personal Care and Cleaning Catalog, physical pages 48–50, as transcribed on the linked product pages. Overall dimensions describe the product envelope, not the connector geometry. YW-10 and YW-10A therefore remain two ordering references. YW-3 / P341 and YW-12 / P342 also require their own compatibility records; the YW prefix establishes no shared fitting.
Make one row for each actual pairing
Ask the supplier to identify the handle revision and head part revision before reviewing samples. A photograph can help identify a part, but it should accompany the written reference. Review attachment and removal according to the current instructions; agree the evaluation method and acceptance criteria before recording a result.
| Handle model / revision | Head part / revision | Paired sample and evidence | Approval record |
|---|---|---|---|
| To confirm: model, catalog ID and revision. | To confirm: supplier part reference, revision and identifying photograph. | To confirm: sample IDs, supplier compatibility statement, matching instructions and agreed review method. | To confirm: reviewer, date, observed result, open issues and status. |
Keep “unconfirmed,” “approved for the recorded pair” and “not approved” distinct. Do not extend an approval to another handle revision or an apparently similar head. A physical-fit review alone does not verify water resistance, electrical safety, cleaning efficacy or dental outcomes.
A hypothetical decision: one refill pack for two handles
Suppose a distributor wants one replacement pack labelled for both YW-10 and YW-10A. This is an illustrative purchasing proposal, not a statement about available products. Start with two unconfirmed matrix rows, one for each handle, using the proposed head reference only after the supplier identifies it.
The matching catalog figures remain useful background, but neither row inherits approval from the other. Ask the supplier to confirm both pairings and provide the applicable samples and evidence. If only one pairing is approved, limit the proposed label to that recorded scope. If either remains unresolved, hold that compatibility claim rather than substituting a model code.
Give the initial set and refill pack separate specifications
The head supplied with a toothbrush and a future replacement pack answer different purchasing questions. An approved sample pair does not establish how many heads arrive in the retail box, whether refill packs can be ordered, or their supply terms. Request those details explicitly.
| Field | Initial retail-set SKU | Proposed refill SKU |
|---|---|---|
| Ordering identity | To confirm: set code and handle revision. | To confirm: refill code and head revision. |
| Included contents | To confirm: exact head reference, quantity and other supplied items. | To confirm: head reference, quantity and protective packing. |
| Approved compatibility | To confirm: paired-sample record. | To confirm: every supported handle and revision. |
| Label and instructions | To confirm: artwork, language and document revision. | To confirm: compatibility wording and instructions. |
| Supply agreement | To confirm: project quantity and packing basis. | To confirm: availability, order quantity and change-notification terms. |
Use the after-sales and spare-parts guide to define the wider supply and warranty agreement. Replacement-pack planning does not create a public stock or replenishment promise.
Connect the accepted pair to the packed product
The listed assembled lengths for the three tabled models exceed their listed unit-box length. Confirm detached-head packing with the actual set, including the arrangement and protection of supplied parts. The dimensional mismatch raises a packing question; it does not establish the number of included heads or a verified pack-out.
Retain the accepted pair, photographs and document revisions through the golden-sample approval process. Link both SKU records to that evidence. Review any head, handle or packing change before reusing the previous compatibility wording.
For a private quotation, send the model, quantity, country, plug type, voltage, packing request, OEM request and destination port, plus the intended refill plan. Yaoyuan Electric supplies factory-direct wholesale projects with MOQ starting from 1000 PCS. Retail and one-piece orders are not accepted; quotation and project timing are confirmed privately.
Buyer questions
Can we print a waterproof or brushing-frequency claim?
The reviewed source IPX entries have no supplied model-matched test evidence, and numerical toothbrush frequency is withheld because its source unit is ambiguous. Request appropriate evidence before approving either claim; head-fit confirmation does not resolve them.
Does a charging connection identify the replacement head?
No. Charging and head compatibility are separate specifications. Use the USB-powered versus rechargeable guide for the electrical wording, then retain the exact head-and-handle pairing in its own record.
Does an approved head imply a replacement interval or clinical benefit?
No. This approval record establishes only its documented scope. Do not invent a replacement interval, bristle specification or dental claim from appearance, operating modes or a physical-fit review.
Specify the handle and the refill question together
Send your shortlisted models and proposed retail-set and replacement-pack requirements. Keep unresolved head pairings visible in the private quotation request.
