BTS6163D
Infineon
Needs validationmedium risk
BTS6163D is a same-package Infineon high-side switch with current derating risk.
Best Alternatives to BTS6143D
BTS6143D replacement options need careful FAE review. Supplied candidates lack verified pinout evidence, and the closest parts require current or thermal derating.
AI replacement insight
Electrical riskmedium
BTS6163D has lower current and higher RON.
Package riskmedium
Package matches, but pinout is not proven.
Firmware risklow
No firmware interface is indicated.
Sourcing riskmedium
Lifecycle data is limited for most parts.
Can it be replaced directly?
No verified pin-compatible replacement is proven from the supplied evidence.
Best replacement path
Start with BTS6163D, then verify pinout, current margin, thermal loss, and diagnostics.
Main risk
Pinout is unverified and the kept candidates are electrically weaker than BTS6143D.
