CREATE TABLE table_65822 ("Part Number" TEXT, "Pins" TEXT, "Body Width/mm" FLOAT, "Body Length/mm" FLOAT, "Lead Pitch/mm" FLOAT)

Which Lead Pitch/mm has a Part Number of tsop40, and a Body Length/mm larger than 18.4?
SELECT MAX("Lead Pitch/mm") FROM table_65822 WHERE "Part Number" = 'tsop40' AND "Body Length/mm" > '18.4'
SELECT MAX("Lead Pitch/mm") FROM "table_65822" WHERE "Body Length/mm" > '18.4' AND "Part Number" = 'tsop40'
