A very close alternative with matching package, voltage, and current, but slightly higher clamping voltage.
The UMW USBLC6-2SC6 is a low-capacitance TVS diode array designed to protect high-speed data lines like USB 2.0 from ESD and surge events. It comes in a SOT23-6 package and offers robust protection with a 5V operating voltage.
Candidates may have lower power/current ratings or higher clamping voltage. Requires engineering review.
All strong candidates share the SOT23-6 package, but pinout must be verified from datasheets.
Direct replacement for USBLC6-2SC6 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
TPUSBLC6-2SC6 by TECH PUBLIC is the most direct alternative, matching nearly all key parameters. However, its slightly higher clamping voltage (15V vs 12V) must be reviewed for system protection requirements.
The primary risk when substituting is a mismatch in electrical protection parameters. A weaker substitute may fail during a surge event, while one with different characteristics (like higher capacitance) can degrade signal integrity.
