The 14-SOIC package is a standard surface-mount footprint, easy to place and reflow alongside other SOIC devices.
Yes, it is RoHS3 compliant — no lead or restricted substances above the exemption thresholds.
The difference is the package. SN74ABT125D is in a 14-SOIC (3.90 mm width) tube. SN74ABT125DW is in a 14-SOIC (7.50 mm width) — a wider body. The DW variant is also typically supplied in tape-and-reel. Functionally they are identical.
The SN74ABT125D is the standard 14-SOIC variant of the 74ABT125 quad buffer. It is a direct functional replacement for any 74ABT125 in the same package. For other buffer families (e.g. 74LVC, 74ACT), verify supply voltage and output drive compatibility — the 5 V supply and 32/64 mA drive differ from lower-voltage families.
