| FFF Compatibility | Pin assignments are identical, but the physical lead configuration is straight (KC package) rather than formed/staggered (KVT package), which may require manually bending the pins or minor adjustments to the PCB footprint.Features the same TO-220 outline dimensions, but uses straight leads instead of staggered/formed leads.Matches all electrical performance characteristics including voltage range, current limit, and slew rate. | This is a surface-mount device (SMD) in a DDPAK-7 / TO-263-7 package, which cannot mount directly onto a through-hole TO-220-7 land pattern.The physical form factor is a surface-mount package (DDPAK) rather than a through-hole package (TO-220).Offers identical electrical capabilities, maximum ratings, temperature range, and functionality. | ||
 AI Summary | OPA548T by Texas Instruments: Power Amplifier 1 Circuit TO-220-7. | The OPA548T-1 is the direct straight-lead variant of the OPA548T from the same product family. It offers identical electrical specifications and internal silicon circuitry, but requires verifying the PCB layout's lead spacing since its pins are straight rather than staggered. This makes it an ideal option if lead-bending or a footprint adjustment is acceptable.
| The OPA548F/500 is the surface-mount DDPAK-7 (TO-263-7) version of the OPA548T. It provides the exact same electrical specifications and feature set, including the adjustable current limit and enable/status pin, making it a reliable alternative if the design can transition from through-hole to surface-mount assembly.
