Is there a pin-compatible replacement for YSPI1050-101M?

Yes, several parts from YJYCOIN's YSPI1040 and YSPI1050 series share the same 11.5x10mm footprint and pinout. However, all identified candidates have significantly different inductance values, so they are not electrically interchangeable without design changes.

What risks should I check before replacing YSPI1050-101M?

The main risks are electrical. Key parameters like inductance, saturation current (Isat), and DC resistance (DCR) must be verified. Using an inductor with incorrect values can lead to circuit instability, inefficiency, or component failure.
