Is there a pin-compatible replacement for SS26FL?

Yes, several candidates like SS56FL and SSL36F use the same 2-pin SMAF package. This makes them physically compatible, but you must verify key electrical parameters like forward voltage before soldering.

What risks should I check before replacing SS26FL?

Before replacing SS26FL, check the forward voltage (VF), as a higher value increases power loss. Also verify the reverse leakage current (IR) and junction capacitance (Cj) to ensure they are suitable for your application's frequency and power budget.
