Is there a pin-compatible replacement for SPH4018H100MT?

Candidates like SWPA4018S100MT and SFE4018A-100M-F-HF share the same 4018 package and are likely pin-compatible, but electrical parameters like RMS current and DCR differ and must be reviewed.

What risks should I check before replacing SPH4018H100MT?

Key risks include differences in RMS current (Irms), which affects thermal performance, and DC Resistance (DCR), which impacts efficiency. Ensure the replacement's ratings meet or exceed your application's needs.

AI replacement insight

Electrical riskmedium

Candidates have different RMS current and DCR ratings.

Package risklow

Top candidates share the same 4018 package.

Sourcing risklow

Multiple vendors offer parts in this package and value.

Can it be replaced directly?

No verified direct drop-in replacement exists. SWPA4018S100MT is a strong functional alternative but requires review of its slightly higher DCR and lower RMS current.

Best replacement path

SWPA4018S100MT is the strongest candidate, offering an upgrade in saturation current, but requires review of other parameters.

Main risk

The primary risk is a mismatch in RMS current (Irms) and DC Resistance (DCR), which can lead to overheating or reduced efficiency.

Recommended alternatives

A functional alternative in the same 4018 package with higher saturation current, but slightly different DCR and RMS current.
