The 10127720-101LF: Ten circuits in two rows with 0.118" row spacing means the board layout needs a 2×5 grid at 3.00 mm pitch. The 0.126" post length gives a solder tail long enough for a through-hole wave joint on standard 1.6 mm boards.
Vibration and Strain: Locking Ramp and Board Lock
The locking ramp fastening type holds the mating connector in place under vibration — the ramp engages with the receptacle latch and prevents accidental disconnection in equipment that sees shock or continuous motion. In a right-angle header the cable pull direction is parallel to the board, so the board lock takes the mechanical load off the solder joints.
This header mates with a Minitek® Pwr 3.0 receptacle housing (crimp or IDC) that accepts the matching female terminals. Termination is solder through-hole. The tin-plated mating surface (100.0 µin thickness) is rated for repeated mating cycles typical of power distribution in industrial equipment — the thick tin layer resists fretting corrosion better than a thin flash.
No official successor or direct cross-reference is listed. The base product number 10127720 covers the series; the -101LF suffix denotes the specific plating and packaging variant.
