The 5040500391: The 1.50 mm pitch means the three pads sit on a 3.00 mm centreline spread — tight enough for compact layouts but still hand-solderable with a fine tip. Current rating depends on the wire gauge you crimp into the mating terminal — the header itself is rated 150 V and the contact material is copper alloy with gold finish.
