A direct cross-vendor alternative from Leiditech with the same part number and key specifications.
LXES15AAA1-133 is an ultra-low capacitance (0.05pF) ESD protection diode from Murata in a 0402 package, designed for high-speed interfaces. Finding a substitute requires matching this extremely low capacitance to preserve signal integrity.
Using a part with higher capacitance will degrade signal integrity on high-speed lines.
The 0402 package is standardized, making physical replacement straightforward.
Ultra-low capacitance parts can have limited availability; check stock for all candidates.
Direct replacement for LXES15AAA1-133 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Prioritize Leiditech's LXES15AAA1-133 as a direct cross-vendor match, or TECH PUBLIC's TPESD0402G15V as a parametrically identical alternative.
Capacitance mismatch is the primary risk, as it can degrade high-speed signal integrity.
