A potential alternative in the same package with matching voltage, but lower current rating and conflicting capacitance data require review.
USBLC6-4SC6 is a 4-channel, ultra-low capacitance ESD protection array for high-speed interfaces like USB. Finding a replacement requires matching its 0.3pF capacitance, 5V rating, and SOT23-6 package to ensure signal integrity and protection.
Capacitance and peak current differences require careful evaluation.
SOT23-6 is a standard package, but pinout must be confirmed.
No firmware interaction is expected for this component type.
Direct replacement for USBLC6-4SC6 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
SRV05-4.TCT from UMW, if its 0.3pF capacitance is confirmed, is the closest match, though with a lower current rating.
Signal degradation due to higher capacitance from an alternative part.

| Feature / factor | USBLC6-4SC6 | SRV05-4.TCT | SRV05-4 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT23-6 | SOT-23-6 | SOT-23-6 | SOT-23-6 — Form factor matches.; SRV05-4: Form factor matches. | |
| Pinout | 6-pin standard | unknown | unknown | unknown — Pinout not verified from datasheet, but likely standard for this function.; SRV05-4: Pinout not verified from datasheet. | |
| Voltage | 5.0V | 5.0V | 5.0V | 5.0V — Reverse working voltage matches.; SRV05-4: Reverse working voltage matches. | |
| Current | 4.7A | 3A | 6A | 3A / 6A — Candidate has lower peak pulse current rating.; SRV05-4: Candidate has higher peak pulse current rating. | |
| Capacitance | 0.3pF | 0.3pF (per datasheet) | 0.6pF | 0.3pF (per datasheet) / 0.6pF — Datasheet claims a match, but other sources show 3pF. Requires verification.; SRV05-4: Capacitance is double the target's, may impact signal integrity. |
Verified drop-in options for USBLC6-4SC6 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
