I find that the trick for finding logic-level mosfets on the Farnell site is to filter for typical threshold Vgs of 2V maximum, and whatever other filters you need e.g. maximum Rds(on) and minimum Id(max). Then check on the datasheet whether a value for Rds(on) is specified at Vgs=5v or less. Filtering on Rds(on) test voltage unfortunately doesn't work because most logic level mosfets are also specified at Vgs=10v, and this is what shows up in the summary data that you can filter on.
PS - those 2 mosfets have a high gate charge (it comes with having a low Rds(on)), so I suggest using the minimum value series resistor to drive the gate, i.e. 100 ohms.
