The post finish is also tin at 35.0µin, matching the solderability requirements for through-hole wave soldering. It is ROHS3 compliant.","metaTitle":"Molex 0039310080 Mini-Fit Jr 5566 Header 8 Pos 4.2mm","metaDescription":"Molex 0039310080 Mini-Fit Jr 5566 header, 8 positions, 4.20mm pitch, dual-row, shrouded, locking ramp, through-hole solder.
