What risks should I check before replacing WIP252012P-4R7ML?

Before replacing, check three main risks: 1) Package Mismatch: Most alternatives are not physically compatible and require a PCB redesign. 2) Pinout/Footprint: Even for matching package sizes, verify the land pattern. 3) Electrical Downgrade: Some options have lower current ratings, which can lead to overheating or failure.

WIP252012P-4R7ML Alternatives, Datasheet & Cross Reference | INPAQ

Finding a substitute for the INPAQ WIP252012P-4R7ML, a 4.7µH power inductor in a compact 2520 package, requires careful matching of electrical and physical properties. While several parts offer the same inductance, key differences in package size, current ratings, and DCR must be evaluated.

AI replacement insight

Package riskmedium

Many alternatives are not form-fit compatible. Even for 2520 packages, exact land patterns must be verified.

Electrical riskhigh

One candidate (ANR252012T4R7M) is a significant electrical downgrade and could cause circuit failure if not carefully evaluated.

Sourcing risklow

Multiple manufacturers offer 4.7µH inductors, but finding one with the exact package and electrical specs can be challenging.

Can it be replaced directly?

Direct replacement for WIP252012P-4R7ML should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with Datasheet verified or Strong match candidates for WIP252012P-4R7ML, then review parametric alternatives for package and electrical fit.

Main risk

The primary risk is physical incompatibility. Most alternatives have different packages (either larger SMD or through-hole) that require a board redesign. For parts with matching packages, there's a risk of electrical downgrade.

Recommended alternatives

A potential pin-compatible alternative with slightly better current ratings and lower DCR in the same 2520 package.

Feature / factor	WIP252012P-4R7ML	APH252010T4R7M	ANR252012T4R7M	Compatibility / risk
Package	2520 (1008)	2520	2520 (1008 Metric)	2520 / 2520 (1008 Metric) — Package size matches. Height is 1.0mm vs target's 1.2mm, which is acceptable.; ANR252012T4R7M: Package size matches.
Current	1.55A	1.6A	0.92A	1.6A / 0.92A — Slightly higher heat rating current (Irms) is an improvement.; ANR252012T4R7M: Significantly lower heat rating current (Irms) is a major downgrade.
Saturation Current A	1.9A	2.0A	1.25A	2.0A / 1.25A — Higher saturation current (Isat) provides more margin.; ANR252012T4R7M: Lower saturation current (Isat) reduces performance margin.
Dcr Ohm	196mΩ	145mΩ	373mΩ	145mΩ / 373mΩ — Lower DCR reduces power loss, which is a significant improvement.; ANR252012T4R7M: Much higher DCR will increase power loss and heat.
