AI replacement insight

Electrical riskmedium

Capacitance and power ratings vary between candidates and must be verified.

Package risklow

All viable candidates use the same DFN1006-2L package.

Firmware risklow

This is a passive protection component with no firmware.

Can it be replaced directly?

ES05D1MC10 is a close functional match, while PESDMC2FD5VB is an upgrade. Both require checking the impact of different capacitance values.

Best replacement path

Upgrade to a lower-capacitance part like PESDMC2FD5VB for better high-speed performance.

Main risk

Junction capacitance mismatch, which can impact signal integrity on high-speed data lines.

Recommended alternatives

A potential upgrade from the same manufacturer with lower capacitance and higher power rating.
