Is there a pin-compatible replacement for BZX84C5V1LT1G?

LBZX84C5V1LT1G is likely pin-compatible as SOT-23 Zener diodes typically follow a standard pinout. However, it is crucial to compare datasheets to confirm the pin functions (Anode, Cathode) before board assembly.

What risks should I check before replacing BZX84C5V1LT1G?

Key risks include Zener voltage tolerance, Zener impedance, and reverse leakage current. Ensure the replacement's parameters fit your circuit's requirements. For physical compatibility, confirm the package dimensions and pinout match exactly.
