The ROHS3 compliance is confirmed, so it meets the current restricted-substance requirements for EU and most global markets. ## Mating and Board Stacking This receptacle mates with the FX10 series header, specifically the FX10A-168P-SV(91) which is the 168-position plug with outer shroud contacts at the same 0.50 mm pitch. The mated pair gives a stack height of 4mm or 5mm between boards — the two heights are achieved by selecting the corresponding header variant. The board guide on both halves aligns the connectors during mating, and the solder retention features keep the parts in place through the reflow process.","metaTitle":"Hirose FX10A-168S-SV(21) FunctionMax Receptacle, 168 Pos","metaDescription":"Hirose FX10A-168S-SV(21) FunctionMax FX10 receptacle, 168 positions, 0.50mm pitch, SMT, gold contacts.
