That listing is the only compatibility claim recorded here: the part is not assumed to fit other generations or other product lines of the same brand.

Buying used

Check the cache module and battery or supercapacitor are present and healthy, and that the firmware level is current for the server's management software. Controllers sold without their cable set or bracket may not install in the server. Ask the seller for photos of the part number label, confirm the return terms, and test the part in a running system before accepting it. Prices vary with condition, so compare several listings for the exact product ID.
