Is there a pin-compatible replacement for BAS16H,115?

Yes, candidates like BAT46WH,115 and SDM2100S1FQ-7 use the same 2-pin SOD123F package and are considered pin-compatible. However, they are functionally different (Schottky vs. switching diode), requiring electrical validation.

What risks should I check before replacing BAS16H,115?

Key risks include differences in diode type (switching vs. Schottky), reverse recovery time (trr), forward voltage (Vf), and reverse leakage current (Ir). These can affect switching speed, efficiency, and signal integrity.

AI replacement insight

Electrical riskmedium

Change in diode type (switching to Schottky) affects key parameters like Vf, Ir, and switching behavior.

Package risklow

Candidates share the same SOD123F package, ensuring mechanical compatibility.

Can it be replaced directly?

No direct, drop-in replacement was identified. All viable candidates are Schottky diodes, which differ functionally from the target high-speed switching diode and require engineering review.

Best replacement path

BAT46WH,115 is the closest option from the same manufacturer but requires validating the functional change from a switching to a Schottky diode.

Main risk

The primary risk is the functional change from a high-speed switching diode to a Schottky diode, which impacts reverse recovery, forward voltage, and leakage current.

Recommended alternatives

A pin-compatible Schottky diode with similar voltage and higher current ratings, but functional differences require review.
