Is there a pin-compatible replacement for IHLP1616BZER4R7M5A?

Sunlord's WPN4012H4R7MT has a compatible 4x4mm footprint, but it is not a drop-in replacement due to significantly lower current (Irms) and temperature ratings, which must be verified in your application.

What risks should I check before replacing IHLP1616BZER4R7M5A?

Key risks are thermal performance and efficiency. The target has a high heat rating current (3.2A Irms) and a very high max temperature (155°C). Most alternatives have lower ratings and must be carefully evaluated to prevent overheating or failure.

IHLP1616BZER4R7M5A Alternatives, Datasheet & Cross Reference | Vishay

Finding a replacement for the Vishay IHLP1616BZER4R7M5A requires balancing its high-temperature (155°C) and high-current (3.2A Irms) capabilities in a compact 4x4mm package. Alternatives may require trade-offs in performance or board layout.

AI replacement insight

Electrical riskhigh

Most alternatives have lower heat current (Irms) or higher DCR, impacting performance and thermals.

Package riskhigh

Few alternatives match the 4x4mm package combined with high performance; redesign is often needed.

Can it be replaced directly?

No direct drop-in replacement has been identified. The closest form-fit candidate, WPN4012H4R7MT, is a significant electrical downgrade and requires careful engineering review.

Best replacement path

For new designs, consider the electrically superior TDK VLS6045EX-4R7M-H. For existing boards, Sunlord's WPN4012H4R7MT is an option but requires significant derating and thermal validation.

Main risk

The primary risk is thermal failure, as the target's high heat rating current (Irms) and 155°C operating temperature are difficult to match in other components.

Recommended alternatives

An electrically superior alternative with higher current and lower DCR, but requires a larger footprint and has a lower max temperature.
