A tip is not a handle.

ET is a replaceable tip fitted over the heater. It is not the same system as an integrated heater cartridge. Check the exact iron and the manufacturer part number before ordering.

No model-specific YIHUA-to-WEP handle interchange test was established in the source research. A listing that says “907 compatible” leaves important details unanswered.

Treat seller claims as a starting point for a model-specific check. Sharing a 900M-style sleeve tip does not make two complete handles interchangeable.

A family label does not establish equivalent plating, thermal performance or manufacturing consistency. The webpage is a companion to the video; raw performance details were not fully audited in our research.

Identify the actual handle and cartridge supplied with a station. Small-cartridge and large-cartridge families should not be merged into one compatibility record.

This is a family distinction, not a ReworkKit certification of a particular station. Confirm the handle and approved cartridge list for that model.

An unlabelled iron cannot be approved from a catalogue photograph. Ask for the station and handle identification before treating a replacement as compatible.
