[SOLVED] Help identify component

[peterpops]

Hi Edaboard

I have four components on a PCB controlling a Pneumatic valve



Two of them have text according the picture

The other too look the same but with the text (my interpretation)
Top row: SU4 or S U4
Mid row: 355
Bot row: Same except letter C

Best regards
Peter
