Quotation scope
A usb 20 to lan rj45 ethernet network adapter request is easy to misread. Many buyers mean a USB 2.0 bus when they type USB 20. The shell may still say gigabit. Those two statements can both be printed and still describe different limits.
Use one sheet so a missing cable or a missing driver does not hide inside a unit price. LinkScope Sourcing 21 does not publish a savings rate. The comparison is the delivered scope, not a percentage off a catalog that this desk does not hold.
| Line | Ask the factory to state | Buyer check |
|---|---|---|
| USB bus | USB 2.0, USB 3.x, or the exact specification name, plus the plug | Do not treat 480 Mbps signaling as a measured file transfer |
| RJ45 PHY | 100BASE-TX, 1000BASE-T, or another IEEE 802.3 PHY the model claims | Bind the claim to the proposed model number |
| Host | Windows, macOS, Linux, or Android builds the driver note covers | A generic chipset page is not your OS test |
| Cable and shell | Included length, latch, shielding, and whether a coupler is in the box | Price a missing 1 m cord as its own line |
| Power | Bus-powered current or an external supply | Confirm the host port can supply it |
| Commercial basis | Quantity, currency, per unit or whole order, Incoterm, freight, duties | Normalize before reading the headline number |
| Exclusions | Software support window, spare pieces, and return route | List them even when the value is none |
Freight to the US destination, duties, a longer patch cord, a dock that actually carries data, and any paid driver support are separate. If the quote is silent, mark the line unknown rather than assuming it is included. An optional target budget needs a currency and a basis: one adapter, or the whole release.
Background: a buyer needs 80 pieces for Android kiosks, some USB-C and some Micro-USB, shipping to Ohio. Process: the sheet splits the two plugs into two lines, asks whether each line is bus powered, and sets 1000BASE-T as preferred with 100BASE-TX as an allowed deviation. Result: factories can price both lines. The desk does not treat the deviation as already accepted. The buyer still reviews the exact model file.
Open the inquiry configurations if a card name should travel with the note. The contact page holds the longer worksheet beside the form.
No. USB 2.0 is commonly described at 480 Mbps signaling. A 1000BASE-T PHY can still be printed on the shell. Ask the supplier which limit the proposed model actually documents, and for the test basis. Do not convert either number into a site throughput claim.
Android version or desktop OS, CPU architecture if you know it, and whether the port is OTG. Add the switch speed on the far end. A 100 Mbps camera port will not become gigabit because the dongle label says gigabit.
OEM-coded parts and compatible modules are a real fork for optics, and a similar fork exists for USB ethernet chipsets. Ask for the chipset identity, the driver license, and a statement of which OS builds were checked. A compatible label is a sourcing option to verify, not a pass.
New and refurbished condition change warranty, connector mating cycle wear, and firmware provenance. Ask the supplier to label condition on the exact model. Do not mix those replies in one price column.
The IEEE 802 overview can frame PHY questions. It does not establish interoperability for an untested pair. FCC equipment authorization, when it applies, has to be shown for the exact model. This page does not certify either item.
Include plug, PHY, quantity, destination, and the timing you want assumed. Mark USB generation if you are unsure.
Supplier preference can be high-end, mid-range, budget-friendly, or undecided. That preference is yours. It is not a score issued by this desk.
