Procurement Notes
Verify availability through authorized distributors or secondary market suppliers, as this component is officially listed as obsolete and not in production by Fairchild Semiconductor. Confirm authenticity and condition when sourcing from third-party vendors due to discontinuation status. Check datasheet compatibility with current designs since newer alternatives may exist.
Selection Notes
Consider that this part is discontinued and no longer in production. Evaluate equivalent or replacement components from current product lines if long-term supply stability is required. Review technical specifications against existing design requirements to ensure functional compatibility before substitution.
Part Context
The KS431SAMFTF belongs to the broader category of programmable shunt regulators produced by Fairchild Semiconductor. It shares functional similarities with related parts such as the KA431 series, which are also two-terminal voltage reference devices used in power management applications. This classification places it within PMIC voltage reference components designed for precision regulation tasks.
Replacement Considerations
Consult official Fairchild Semiconductor documentation for confirmed substitute part numbers. Verify electrical and pinout compatibility with any proposed replacements to maintain circuit integrity.
