Is this compatible with the Hope Mini 2002 caliper?

Just checking, because although it's the right part number for my brakes (Hope Mini 2002 / HBSP117) this looks different - mine are just plain metal pistons, not phenolic. Please advise - thanks.

The piston is correct, Hope upgraded all pistons to the new type. SK 26/11/25
