Procurement Notes
Verify end-of-life status as this component may be obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors only, as stock is limited. Ensure compliance with RoHS directives before procurement. Check for valid replacement part numbers if production continuity is required.
Selection Notes
Select this component when integrated surge protection and filtering are required in a single package. The 12 VDC rating suits low-voltage DC circuits. Verify that the 7 A current rating meets transient energy requirements. Ensure PCB layout accommodates the 2.5 mm lead spacing and radial form factor.
Part Context
This part belongs to the VFS9V series of varistors manufactured by Murata Electronics. The series combines varistor technology with capacitive elements to offer combined surge suppression and noise filtering functions. These components are typically used in consumer electronics and industrial equipment requiring compact protection solutions.
Replacement Considerations
Public confirmed substitute part numbers include VFS9VD31B223Q93J and VFS9VD31B223Q50B. Verify pin compatibility and electrical specifications before substitution.
