The crimp termination means you're building a custom harness length, not buying a pre-terminated cable assembly. If the BOM line only lists this housing, the build stops at the crimp press until the terminals arrive. ## Mating Half and Latch Lock The mating connector is a Micro-Fit 3.0 pin header — typically the 43045 series vertical or right-angle headers with 0.118\" (3.00 mm) pitch and 10 circuits. The latch lock on this receptacle clicks onto the header's locking ramp, giving positive retention against vibration. For a free-hanging harness, the latch is what keeps the pair mated when the cable gets tugged; without it, the contacts would back out of the header pins over time in a moving assembly.","metaTitle":"Molex Micro-Fit 3.0 0436451000 Receptacle, 10 Circuit","metaDescription":"Molex 0436451000 Micro-Fit 3.0 receptacle, 10 positions, 3.00 mm pitch, latch lock, crimp termination, black polyester housing.
