This header mates with any Mini-Fit Jr 5566 series receptacle housing — the standard mating half is a 10-position, dual-row crimp receptacle (Molex 39-01-2100 or equivalent). The square pins (0.040\" typical) provide a solid solder joint and resist rotation during cable flex. It is ROHS3 compliant.","metaTitle":"Molex 0039299107 Mini-Fit Jr 5566 Header 10 Pos 4.2mm","metaDescription":"Molex 0039299107 Mini-Fit Jr 5566 header, 10 positions, 4.20mm pitch, shrouded, board lock.
