A replacement-part request can become unreliable when a buyer starts with a generic label such as ‘nose-trimmer head’ or ‘USB cable.’ A part that looks familiar may have a different fixing point, revision, power arrangement or approved use. Begin with the exact device model and the part’s evidence trail, then ask the supplier to confirm fit and availability for the selected project.
1 — Identify the reference product before naming a part
The public YH-3100 nose hair trimmer record lists a 0.75 m Type-C cable and a cleaning brush. It also identifies the model’s IPX5 rating, 3.7 V 320 mAh battery and 5 V=1 A input. These fields are a useful starting record for YH-3100; they do not establish that another trimmer’s head, cable, brush, battery or housing will fit it, or that a replacement item is currently supplied.
Put the model code, product revision, market and a clear photo of the fitted part on the first line of a replacement request. If the request refers to a trimming head, add the drawing or approved sample reference. If it refers to a cable, record the connector and the product’s stated input separately. A category name or a similar product photo is not enough to approve compatibility.
| Request field | Record with the selected item | Leave open until the supplier confirms it |
|---|---|---|
| Reference device | Exact model code, such as YH-3100, plus colour or revision where relevant | Whether another model shares the same interface or internal design |
| Requested part | Head, cable, brush or other named item, with a photo or drawing reference | Part number, availability and approved replacement status |
