Central Semiconductor Corp list them as having the same die size, check their documents named "Device datasheet" here https://my.centralsemi.com/product/partpage2.php?part=CP310-MPSA42 and here https://my.centralsemi.com/product/partpage2.php?part=CP310-MJE340, now I don't know if other manufacturers have the same data on theirs, but at least one manufacturer seems to use the same die in both types (maybe they will confirm if you ask them?).
