Is there a pin-compatible replacement for BAS416?

No pin-compatible (pin-to-pin) replacement has been verified. All reviewed candidates have different physical packages (e.g., SMA) that are not compatible with the target's SOD-323 footprint.

What risks should I check before replacing BAS416?

The main risks are physical incompatibility and electrical performance. Verify the substitute's package and land pattern match your PCB. Critically, check the reverse recovery time (trr) to ensure it's fast enough, as the BAS416 is an ultra-fast diode (3ns).

BAS416 Alternatives, Datasheet & Cross Reference | Yangjie Technology

Finding a substitute for the BAS416 fast switching diode requires careful matching of its 100V rating, 3ns recovery time, and compact SOD-323 package. Alternatives exist but often require board layout changes.

AI replacement insight

Package riskhigh

All candidates are in much larger packages (SMA vs SOD-323) requiring a new PCB layout.

Electrical riskmedium

Candidates have slower switching speeds (trr) which may not be suitable for the original application.

Can it be replaced directly?

No direct drop-in replacement found; all candidates have incompatible packages.

Best replacement path

Functional alternatives with board redesign.

Main risk

Physical package mismatch requiring PCB redesign and potentially slower switching speeds in alternatives.

Recommended alternatives

A functional alternative with higher voltage and current, but in a much larger package requiring board redesign.
