IIRC, these should be named CAPR:

CAPR-2750P-3050L-1900W__Panasonic.fp
CAPR-3750P-4150L-1800W__EPCOS.fp

BTW, according to IPC7351 for CAPR type footprints the height should be
included, and length and width change positions:

CAPR2750-1900X3050X2600.fp
CAPR2750-1900X3050X2950.fp
CAPR3750-1800X4150X3250.fp

that is: $Type $Pitch "-" $Width "X" $Length "X" $Height

Maybe even better is to state the lead diameter (d), which may vary
across vendors, as well:

CAPR-2750P-3050L-1900W-2600H_80d_Panasonic.fp
CAPR-2750P-3050L-1900W-2950H_80d_Panasonic.fp
CAPR-3750P-4150L-1800W-3250H_100d_EPCOS.fp

Just my EUR 0.02 on this subject.

Kind regards,
