Original Part
SRAM - Asynchronous Memory IC 4Mbit Parallel 15 ns 48-CABGA (9x9)
Alternative Part
SRAM - Asynchronous Memory IC 4Mbit Parallel 10 ns 48-MiniBGA (8x10)
SRAM - Asynchronous Memory IC 4Mbit Parallel 10 ns 48-TFBGA (6x8)
1. AS7C34098A-10BINTR Substitution Conclusion
This part is fully compatible with the original component in core electrical specifications (density, bit width, interface, voltage) and offers improved performance with a faster access time (10 ns). However, its 48-MiniBGA (8x10 mm) package is not footprint-compatible with the original 48-CABGA (9x9 mm) package. The physical dimensions and ball layout differ, preventing a direct "drop-in" replacement. A PCB redesign is required to accommodate the new package, which is the primary obstacle for this substitution.
2. IS61WV25616EDBLL-10BLI-TR Substitution Conclusion
This device is also logically compatible with the original part and provides enhanced system adaptability through a faster access speed (10 ns) and a wider supply voltage range (2.4V to 3.6V). Its 48-TFBGA (6x8 mm) package, however, is significantly smaller than the original 9x9 mm package, resulting in a different ball map and physical pinout incompatibility. Direct replacement is not feasible; a PCB layout revision based on the new package specifications is mandatory.
