Intel 5962-8953402MXA

5962-8953402MXA is a military-standard ordering code associated with Intel MG8038720. It belongs to the 80387 numeric coprocessor family used alongside compatible 80386 processors to execute x87 floating-point, integer, and BCD numeric operations in hardware.

The site record identifies a 68-CPGA package for 5962-8953402MXA, consistent with the DLA mapping to the MG-prefixed Intel part.

Layout checks

• Verify pin-one orientation and ceramic body outline.
• Use the controlled 68-pin socket or through-hole footprint.
• Confirm board-level clock and coprocessor interface routing.
• Observe insertion-force, lead-straightness, and ESD controls.

The expected package JPG is not present locally or confirmed online; publishing must wait for image verification.

The 68-pin interface includes host-data, command/status, clock, synchronization, control, power, and ground connections used by the 80386/80387 coprocessor interface.

Use the exact Intel and military package documentation for individual pin assignments.

Electrical limits, timing, screening, and case-temperature requirements must be taken from the controlled drawing and applicable Intel documentation.

No drop-in replacement is asserted. Verify SMD revision, vendor-similar PIN, 20 MHz grade, CPGA outline, pin map, voltage and timing, screening level, host chipset behavior, BIOS/software assumptions, and x87 exception handling.

The official DLA handbook lists Intel as the approved source and MG8038720 as the vendor-similar PIN for this exact SMD code. Use revision-controlled DLA and Intel documentation during design maintenance and procurement.

Verify the full SMD marking, Intel source identification, lot/date code, 68-pin ceramic PGA, screening documentation, traceability, pin condition, and storage history against approved procurement records.
