Procurement Notes

Verify the specific suffix MXA indicates the lead-free tray packaging option when sourcing from authorized distributors. Confirm the L5962 qualification status and lot traceability documentation are included with the shipment. Check for current production status as aerospace components may have limited availability or long lead times due to specialized manufacturing processes.

Selection Notes

Select this part when radiation tolerance and long-term reliability are critical requirements over standard commercial SRAMs. Ensure the system voltage matches the single +5V specification. Consider the physical package dimensions and pinout compatibility with existing PCB layouts designed for 28-pin SOIC packages. Verify that the access speed meets the timing constraints of the host processor interface.

Part Context

This component belongs to the Analog Devices L5962 family, which consists of parts screened and tested to meet strict military and aerospace standards. The 5962 prefix identifies it as a direct-read drawing number part, ensuring consistency with government specifications. The MXA suffix typically denotes a specific packaging variant, often tray-packed for automated assembly in high-reliability manufacturing lines.

Replacement Considerations

Direct replacements must match the 1M-bit density, 8-bit width, and 28-pin SOIC package. Verify that any substitute offers comparable radiation hardness levels if operating in space environments. Cross-reference with other L5962 qualified SRAMs from Analog Devices or other qualified vendors like Microchip or NXP, ensuring electrical parameters and pinouts are identical.
