Press-fit allows solderless assembly into plated through-holes, which is useful for backplane or high-reliability boards where rework is a concern. The solder option gives a traditional through-hole joint for applications where wave or hand soldering is preferred. The post length is 0.246\" (6.25mm), which fits standard PCB thicknesses in the 1.6mm to 2.4mm range. ## Mating Half and Application Fit This header mates with standard Mini-Fit Jr. receptacle housings that accept 4.20mm pitch crimp terminals. The 14-position, dual-row layout is common for power distribution in industrial control panels, medical equipment, and telecom gear where the 4.20mm pitch provides a good balance between board density and current capacity. The black housing color is standard for the series.","metaTitle":"Molex 0438790027 Mini-Fit BMI Header 14 Pos 4.2mm","metaDescription":"Molex 0438790027 14-position vertical header, 4.20mm pitch, tin-plated contacts, press-fit/solder termination.
