The 'STRLPBF' suffix indicates tape-and-reel packaging and ROHS3 compliance. Electrically it matches the IRFZ44N ratings — 55 V, 49 A, 17.5 mOhm Rds(on) — so it is a drop-in replacement for any D2PAK IRFZ44N variant."},{"question":"What is the closest functional second-source for IRFZ44NSTRLPBF if stock is low?","answer":"The IPD50R950CEAUMA1 is a CoolMOS CE N-channel MOSFET in a similar DPAK package, but it is a 500 V, 4.3 A device with 950 mOhm Rds(on) — a completely different voltage and current class. It is not a functional second-source for the 55 V, 49 A IRFZ44N.
