Huawei R4850G2 and R4875G1 rectifier modules

The R4850G2 is one of the most widely deployed 48V rectifiers in the world and the single most requested part number in this category. It is current, plentiful and heavily traded — which also means it is the part number most often supplied as a repaired pull. We quote new or genuine new-old-stock only, and we say which.

Availability & lifecycle

Active and widely available. The real risk on this model is not scarcity, it is condition: a saturated secondary market means repaired and relabelled units circulate freely.

What to send us

The exact model marking (R4850G2 and R4875G1 differ in current rating, not just in name) and a photo of the subrack. If it is going into an ETP48 system, tell us — the system variant matters.

Compatibility notes

R4850G2 and R4875G1 are not interchangeable by default. Confirm the plant's current rating and the controller's expectations before mixing them in one shelf.

Common questions about this family

Can I mix R4850G2 and R4875G1 modules in the same shelf?

Not by default. They differ in current rating, and mixing ratings affects how the modules share load and what the controller expects to see. Send the plant model, the controller and the marking on the existing modules and we will confirm before you order rather than after.

How do I avoid getting a repaired R4850G2 sold as new?

The R4850G2 is one of the most heavily traded rectifiers in the world, which means repaired and relabelled units circulate freely. Ask the supplier to state in writing whether the unit is new or genuine new-old-stock — we put that on every quotation — and be sceptical of prices far below the rest of the market.
