Is there a pin-compatible replacement for PESDNC2FD7VB?

Yes, several candidates like HESDNC7VB1AF-A and LESD8D12CT5G-HXY use the same DFN1006-2L package and 2-pin layout, making them potential pin-compatible replacements. Always verify the datasheet footprint.

What risks should I check before replacing PESDNC2FD7VB?

Verify the reverse standoff voltage (VRWM), clamping voltage (Vc), capacitance, and peak power rating. A higher VRWM or Vc may not protect the circuit, and higher capacitance can affect high-speed signals.
