Is there a pin-compatible replacement for PESD1CAN,215?

PESD2IVN24-TR and SZNUP2105LT1G use the same SOT-23 package and are for the same 2-line CAN bus application, making them likely pin-compatible. However, pinout verification against the datasheets is always recommended.

What risks should I check before replacing PESD1CAN,215?

Key risks include ensuring the replacement's clamping voltage, peak power, and capacitance meet your circuit's needs. For cross-vendor parts, verify automotive qualification (AEC-Q101) and pinout compatibility.

AI replacement insight

Electrical risklow

Top candidates offer matched or superior electrical protection.

Package risklow

All top candidates use the same SOT-23 package.

Sourcing risklow

Top candidates are active parts from major manufacturers.

Can it be replaced directly?

Yes, several direct replacements exist. PESD2IVN24-TR is a potential drop-in upgrade from the same manufacturer, Nexperia.

Best replacement path

Upgrade to PESD2IVN24-TR for a same-manufacturer solution or switch to SZNUP2105LT1G for a qualified cross-vendor part.

Main risk

The main risk is ensuring pin-for-pin compatibility and that the replacement's dynamic characteristics (like capacitance) do not negatively impact CAN bus signal integrity.

Recommended alternatives

Active Nexperia part in the same package with improved ESD rating and lower clamping voltage.
