Is there a pin-compatible replacement for LXES15AAA1-153?

Yes, several bidirectional ESD diodes in a 0402 package, such as Leiditech's version of LXES15AAA1-153, are expected to be pin-compatible. As they are simple 2-pin devices, replacement is straightforward, but electrical verification is still crucial.

What risks should I check before replacing LXES15AAA1-153?

The most critical parameter is capacitance; a higher value can degrade high-speed signals. Also, verify the clamping voltage, leakage current, and ESD withstand ratings to ensure the replacement provides equivalent protection for your circuit.
