Is there a pin-compatible replacement for SLESDA33CP?

Yes, several parts like Rclamp3311P-N share the same DFN1006 package and 2-pin layout. However, electrical parameters like power rating and clamping voltage must be verified for your application.

What risks should I check before replacing SLESDA33CP?

Key risks include: 1) Peak Pulse Power (Ppp) - ensure it meets or exceeds 84W. 2) Clamping Voltage (Vc) - ensure it's low enough to protect downstream components. 3) Capacitance - ensure it's not too high for your data line speed.

AI replacement insight

Electrical riskmedium

Candidates have varying power and clamping voltage ratings that must be checked.

Package risklow

All viable candidates use the same DFN1006 package, suggesting physical compatibility.

Can it be replaced directly?

No verified direct drop-in replacement is available. Rclamp3311P-N is a strong candidate but requires engineering review due to a minor difference in power rating.

Best replacement path

Rclamp3311P-N is the closest alternative, featuring the same voltage and package, with a slightly lower power rating that may be acceptable in many designs.

Main risk

The main risk is substituting with a part that has a lower power rating or higher clamping voltage, which could compromise circuit protection.

Recommended alternatives

A strong alternative in the same package and voltage, with a slightly lower power rating.
