NFM21PC475B1A3D may fit 0805 boards but needs voltage and pinout review.
NFM21PC105B1C3D alternatives need careful review because no checked pinout evidence is present. Same-size candidates have voltage, current, or capacitance tradeoffs.
candidates change V, I, or C
0805 matches for kept parts, pinout not checked
passive EMI part
lifecycle fields limited
Direct replacement for NFM21PC105B1C3D should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use NFM21PC475B1A3D only on rails within 10V; use NFM21PC474R1C3D only if lower current and capacitance are acceptable.
Electrical ratings and unverified pinout.

| Feature / factor | NFM21PC105B1C3D | NFM21PC475B1A3D | NFM21PC474R1C3D | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 3-pin | 0805 3-pin | 0805 3-pin | 0805 3-pin — mechanical likely same class; NFM21PC474R1C3D: mechanical likely same class | |
| Pinout | 3-terminal feedthrough | 3-terminal feedthrough | 3-terminal feedthrough | 3-terminal feedthrough — pin functions not checked; NFM21PC474R1C3D: pin functions not checked | |
| Voltage | 16V | 10V | 16V | 10V / 16V — only for low-voltage rails; NFM21PC474R1C3D: no 1.1x margin | |
| Current | 4A | 6A | 2A | 6A / 2A — current margin improves; NFM21PC474R1C3D: 50% current rating | |
| Temperature | -40 to 85C | -40 to 85C | - | -40 to 85C — range aligns | |
| Application | 1.0uF filter | - | 0.47uF filter | 0.47uF filter — lower shunt capacitance |
Verified drop-in options for NFM21PC105B1C3D are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
