Is there a pin-compatible replacement for CDRH127N-470M?

No verified pin-compatible replacement has been found. While HX CYH127-47UH shares the same package dimensions, its much lower current rating (2.5A vs 4.0A) makes it a risky, non-equivalent substitute that is not recommended without a full circuit re-evaluation.

What risks should I check before replacing CDRH127N-470M?

Before replacing, check three main things: 1) Package footprint, as the best alternatives require a PCB change. 2) Current rating, ensuring the replacement meets or exceeds the original 4.0A. 3) Saturation current (Isat), which is missing on the original part but critical for avoiding inductor saturation under load.

AI replacement insight

Package riskhigh

The strongest electrical alternatives have different package footprints, requiring board redesign.

Electrical riskmedium

One candidate is a current downgrade. The target's missing saturation current spec requires careful application review.

Can it be replaced directly?

No direct drop-in replacement has been identified. The candidate with a matching package, HX CYH127-47UH, has a significantly lower current rating and is a high-risk downgrade.

Best replacement path

Functional alternate. FCH1365-470M offers a significant electrical upgrade but requires a larger PCB footprint. FCH1050-470M is electrically similar but also requires a layout change.

Main risk

The primary risk is package incompatibility. The best electrical alternatives require a PCB layout change. A secondary risk is the target's unspecified saturation current, which must be considered for any replacement.

Recommended alternatives

A functional alternative with very similar electricals, but requires a PCB layout change due to a different package size.
