Is there a pin-compatible replacement for SS58?

Yes, parts like SS5200 and SS510 use the same SMA (DO-214AC) package and 2-pin layout, making them physically compatible. However, electrical differences like reverse leakage must be checked.

What risks should I check before replacing SS58?

The main risk is higher reverse leakage current in alternatives like SS5200 (1mA) and SS510 (0.5mA) compared to SS58 (0.05mA). This can affect power efficiency and circuit behavior, especially in low-power or temperature-sensitive applications.

AI replacement insight

Electrical riskmedium

Higher reverse leakage current requires application-specific review.

Package risklow

Package is a standard SMA (DO-214AC).

Sourcing risklow

Multiple manufacturers produce similar parts.

Can it be replaced directly?

No drop-in replacement is confirmed. SS510 and SS5200 are strong candidates but require review due to higher reverse leakage current.

Best replacement path

SS510 or SS5200, pending review of reverse leakage impact.

Main risk

Increased reverse leakage current may impact power consumption and thermal performance.

Recommended alternatives

A form, fit, and functional alternate with a higher voltage rating (100V) but also higher reverse leakage.
