Automotive-grade upgrade with higher current ratings, but requires a mechanical check due to its taller package.
FSA0620-4R7MT is a 4.7µH shielded power inductor for high-frequency power supplies. Finding a replacement requires matching its 3.5A RMS current, 5.0A saturation current, and low-profile 2.0mm height package.
Most alternatives are 3mm to 5mm tall, vs the target's 2mm height.
Many candidates offer superior current ratings and lower DCR.
No direct drop-in replacement is confirmed. All strong candidates have different package dimensions, especially height, requiring a design review.
Upgrade to an automotive-grade part like Panasonic ETQP3M4R7KVN, but you must verify the increased package height (3.0mm vs 2.0mm) is acceptable.
Package height mismatch is the primary risk, as most alternatives are significantly taller than the target's 2.0mm profile.

| Feature / factor | FSA0620-4R7MT | ETQP3M4R7KVN | CMPI0630-4R7M | VLS6045EX-4R7M-H | Compatibility / risk |
|---|---|---|---|---|---|
| Inductance | 4.7µH | 4.7µH | 4.7µH | 4.7µH | 4.7µH — Inductance matches target.; CMPI0630-4R7M: Inductance matches target.; VLS6045EX-4R7M-H: Inductance matches target.; CYA0650-4.7UH: Inductance matches target. |
| Current | 3.5A | 4.6A | 5.5A | 4.2A | 4.6A / 5.5A / 4.2A / 6.0A — Higher RMS current rating provides more thermal margin.; CMPI0630-4R7M: Higher RMS current rating.; VLS6045EX-4R7M-H: Higher RMS current rating.; CYA0650-4.7UH: Significantly higher RMS current rating. |
| Saturation Current | 5.0A | 9.8A | 6.5A | 5.8A | 9.8A / 6.5A / 5.8A / 8.0A — Significantly higher saturation current.; CMPI0630-4R7M: Higher saturation current.; VLS6045EX-4R7M-H: Higher saturation current.; CYA0650-4.7UH: Significantly higher saturation current. |
| Dcr | 56mΩ | 29mΩ | 42mΩ | 27mΩ | 29mΩ / 42mΩ / 27mΩ / 26mΩ — Lower DCR improves efficiency.; CMPI0630-4R7M: Lower DCR improves efficiency.; VLS6045EX-4R7M-H: Lower DCR improves efficiency.; CYA0650-4.7UH: Lower DCR improves efficiency. |
| Package | ~6.6x6.6x2.0mm | 6.4x6.0x3.0mm | ~7.1x6.6x3.0mm | 6.0x6.0x4.5mm | 6.4x6.0x3.0mm / ~7.1x6.6x3.0mm / 6.0x6.0x4.5mm / ~7.1x6.6x5.0mm — Similar footprint but 1mm taller. Verify clearance.; CMPI0630-4R7M: Slightly larger footprint and 1mm taller. Verify clearance.; VLS6045EX-4R7M-H: Significantly taller package (4.5mm vs 2.0mm).; CYA0650-4.7UH: Significantly taller package (5.0mm vs 2.0mm). |
The Panasonic ETQP3M4R7KVN is a strong alternative, offering higher current ratings and a similar footprint, though it is slightly taller (3.0mm vs 2.0mm). Always verify mechanical clearance.
