W9825G6KH-6I is the closest same-family option; confirm pinout and CAS timing.
W9825G6KH-6 is a 256Mbit x16 Winbond SDRAM. The closest listed candidate is W9825G6KH-6I, pending pinout and timing review.
CAS and timing need review.
Best candidates list TSOP-54.
Density changes may need controller changes.
Lifecycle text is limited.
Direct replacement for W9825G6KH-6 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Check W9825G6KH-6I first, then verify pinout, CAS timing, and SDRAM controller settings.
Pinout and timing tables were not checked.
