| FFF Compatibility | The part shares the identical TO-263-7 (DDPAK-7) package footprint, lead spacing, and pin assignments.Physical dimensions, package design, and copper tab connection are identical to the original part.All electrical specifications, including the 60V max supply, 5A output capability, and adjustable current limiting are identical. | The component is packaged in the identical TO-263-7 (DDPAK-7) surface-mount package with the same pin layout.Physical dimensions, thermal tab connection, and mounting style are identical to the original part.All electrical characteristics, including current-limiting logic and the enable/shutdown status pin, are identical. | ||
 AI Summary | OPA548F/500G3 by Texas Instruments: Power Amplifier 1 Circuit TO-263 (DDPAK-7). | This is the active, direct replacement designated by Texas Instruments. The G3 suffix originally represented a transitional green/lead-free status, which has since been integrated into the standard active MPN. It is a true drop-in replacement with no design changes required.
| This is an active packaging alternative from Texas Instruments that is identical in form, fit, and function. The only difference is the standard packaging quantity, which offers a smaller tape-and-reel quantity (250 units instead of 500).
