Hi,
Thank you for your interest in NXP Semiconductor products,
The part number misses some parameters for its differentiation. It misses if it's industrial or automotive.

However, both packages have a thermal resistance of the following, it depends on every customer to take the thermal resistance, environmental and processing load conditions to select an specific part.

As a suggestion, you could use the NXP EVK heatsink part:
Name: HEAT SINK 40*40*15MM, BLACK ALUMINUM
Manufacturer: Suzhou Puqiao Electronic CO.,LTD
Manufacturer part number: NXP-PQ-HS0002
