PDPMAA1712-470MP
PROD
Needs validationhigh risk
Superior electrical performance (higher current, lower DCR) but in a completely different (Through-Hole) package.
Best Alternatives to FXC1040-470M
Finding a replacement for the FXC1040-470M, a 47µH power inductor, requires balancing its 3A current rating and compact SMD package. While no direct drop-in was found, several functional and parametric alternatives exist that may suit your design with careful review.
AI replacement insight
Package riskhigh
Several candidates are Through-Hole vs the SMD target, requiring board redesign. SMD alternatives have different footprints.
Electrical riskmedium
Some SMD candidates have a lower RMS current rating (Irms), which could lead to overheating if not properly derated.
Can it be replaced directly?
No direct drop-in replacement was found. All candidates require engineering review for package differences or weaker electrical parameters like RMS current.
Best replacement path
For SMD, review SDRI127-470MT, but verify its lower 2.5A RMS current and larger footprint. For new designs not constrained by SMD, PDPMAA1712-470MP offers superior electrical performance in a through-hole package.
Main risk
The primary risks are package incompatibility (SMD vs. Through-Hole) and lower RMS current ratings in otherwise similar SMD alternatives.

Questions & answers
The best alternative depends on your design constraints. For highest electrical performance in a new design, consider the through-hole PDPMAA1712-470MP. If you must use an SMD part, SDRI127-470MT is an option, but you must verify its lower 2.5A current rating and different footprint are acceptable for your application.
