Is there a pin-compatible replacement for FCH5030-100M?

No pin-compatible upgrade has been found. MDA5030-100M is pin-compatible in a 5030 package but has a lower saturation current (2.5A vs 3.5A), making it a high-risk downgrade.

What risks should I check before replacing FCH5030-100M?

First, check package and footprint compatibility; most alternatives are larger. Second, verify saturation (Isat) and rated (Irms) currents meet your application's needs. Finally, check DC Resistance (DCR).

Finding a substitute for the FCH5030-100M 10µH inductor involves balancing package size with electrical performance. No direct drop-in upgrades are available, but functional alternatives offer superior current handling if a PCB redesign is possible.

AI replacement insight

Package riskhigh

Most alternatives have different footprints, requiring board redesign.

Electrical risklow

Most alternatives are electrical upgrades, but one same-package option is a downgrade.

Can it be replaced directly?

No direct, pin-compatible upgrade for the FCH5030-100M has been identified. The only part with the same 5030 package, MDA5030-100M, has a lower saturation current.

Best replacement path

For new designs, use an upgraded part like TMPA1265SP-100MN-D. For existing boards, no direct upgrade is found; MDA5030-100M fits but is a downgrade.

Main risk

The primary risk is package incompatibility. Most alternatives are electrically superior but will not fit on the existing PCB footprint.

Recommended alternatives

An electrical upgrade in a different package size, requiring a board redesign.
