Parts For Hi 10

Dose any one know where to fine parts for the HI 10 Air

Current Limited, Power Distribution Switch with active high.
For example WS4601 and TPS2065.

Thank You Kind Sir
May The Road Rise Up To Meet You

And this two (WS4601 and TPS2065) would replace the 7R2A

These microcircuits are interchangeable.

Thank You For the Help
