- 3SU11001HA201FH0: Same series and front-mounting footprint. Shares the push-pull operator form but uses a DPST-NO/NC contact block, adding a normally-open pole compared to the seed's single NC pole.
- 3SU11001HB201CH0: Shares the SPST-NC circuit, IP rating, and 22.3 mm cutout. Differs in reset mechanism — this part uses twist-release operation rather than push-pull.
- 3SU11001HB201CG0: Identical circuit, rating, and IP class to 3SU11001HB201CH0. Differs in package quantity (bulk vs box) and twist-release reset.
