Compatible Dell Latitude 3440 E3440 replacement fan

This DBTLAP cooling fan replaces part numbers 228K4, BN7507S5H-004P and 023.100U0.0011 in Dell Latitude 3440 and E3440 laptops. It is a new component tested before shipping. Buyers who need a different Dell model or a complete cooling assembly cannot use this part.

Electrical specification 5V 0.4A

The fan operates at 5 volts and draws 0.4 amps, matching the original power requirements for the supported Latitude models. This electrical rating is fixed by the laptop's motherboard header and cannot be altered. Systems that supply a different voltage or current limit will not run this fan correctly.

Critical part-number match

Compatibility depends entirely on confirming that the existing fan carries one of the listed part numbers such as 228K4 or BN7507S5H-004P. Visual comparison with the product photos is essential before ordering. Installing a fan with a different part number risks mechanical mismatch and connector incompatibility.
