Alternative Part Number

  • CY7C168A-45DMB --: Pin-compatible 4Kx4 static RAM in a ceramic DIP with 883-style screening, functionally equivalent to the HM1-6508.
  • AM2168-45DMB --: 4Kx4 SRAM with similar access time and military temperature range, a common second-source substitute for the HM1-6508.
  • IDT7168L-45DB --: 4Kx4 CMOS SRAM in a ceramic package offering comparable speed and pinout, suitable as a drop-in replacement.
  • P4C188-35PC --: Pin-compatible 4Kx1 static RAM with similar access time, commonly used as a drop-in replacement for the 6508 family in military and industrial systems.
  • CY7C128A-35PC --: 4Kx1 asynchronous SRAM with comparable speed and DIP pinout, widely available and often substituted for 6508-type devices.
  • IDT6116SA35TP --: 2Kx8 SRAM that can serve equivalent memory roles in many legacy designs; check address decoding and pinout before substitution.
