Direct answer
The US Breville Café Roma ESP8XL uses Breville's 50 mm portafilter system. Breville's current ESP8XL page lists a Portafilter Assembly 50mm plus matching 50 mm filters, grouphead collar and spoon tamper; the current 50 mm assembly record is SP0003216. Do not buy Breville's 54 mm or 58 mm portafilter families for this machine.

|---|---|---|---|
| Breville Portafilter Assembly 50mm — SP0003216 | Café Roma ESP8XL | Fits | Breville lists the 50 mm assembly under the current US ESP8XL parts record and maintains the matching SP0003216 part page. |
| Breville 50 mm one-cup / two-cup filters and related 50 mm parts | Café Roma ESP8XL 50 mm system | Fits | The official ESP8XL page lists 50 mm filters, a 50 mm grouphead collar and a 50 mm spoon tamper. |
| Breville Portafilter Assembly 54mm — SP0027237 | Listed 54 mm BES machines, not ESP8XL | Does not fit | Breville's current works-with list names BES870, BES876, BES878, BES880 and BES881; the assembly is a different nominal size from ESP8XL's 50 mm system. |
| Breville Portafilter Assembly 58mm — SP0001817 | Listed 58 mm Oracle / Dual Boiler machines, not ESP8XL | Does not fit | Breville's current works-with list names BES920, BES985, BES995 and BEP920; it is not the Café Roma family. |

Match the ESP8XL model label
Breville's current US page identifies the Café Roma as model ESP8XL and marks the machine discontinued. Use the complete label when shopping. Do not transfer this result to another regional Café Roma variant or to a listing that names only the product nickname.
The official parts chain points to 50 mm
The ESP8XL product page groups a Portafilter Assembly 50mm with 50 mm one-cup and two-cup filters, a 50 mm grouphead collar and a 50 mm spoon tamper. Breville also maintains the SP0003216 page for its selected-machine 50 mm portafilter assembly. Together, those records are stronger evidence than a marketplace measurement or a visual match.
Why 54 mm and 58 mm Breville parts are different
Breville maintains separate current assembly records for 54 mm and 58 mm machines. The 54 mm page names Barista-family BES models, while the 58 mm page names the Dual Boiler and Oracle-family models. Neither list includes ESP8XL, and both nominal diameters differ from the Café Roma's 50 mm record.
A 50/51 mm marketplace label is not enough
A seller may measure the basket opening, basket interior or another surface and round it differently. Require the listing to name ESP8XL and compare its lug count, lug position, locking direction and included basket details. Treat a generic size-only claim as unverified rather than forcing the handle into the group head.
Check what comes with the replacement
The ESP8XL instruction booklet describes three stainless steel filters: single shot, double shot and pod. A replacement portafilter listing may include fewer baskets or none, so verify the package contents separately from handle compatibility. The manual instructs users to place the holder left of center and rotate it right until locked, and never remove it during brewing while the machine is under pressure.
Evidence boundary
This guide records current US Breville parts pages and the official ESP8XL instruction booklet. It is not a hands-on fit test, does not confirm stock or price, and does not certify a third-party 50/51 mm product that omits the ESP8XL model number.
