Same-series socket contacts
Within the AMPMODU Mod IV socket line, the 87523-5 (20-24 AWG, tin, 50.0µin) sits alongside the 87523-6 which is identical in specs but packaged in Bulk, and the 87756-6 which accepts 22-26 AWG wire — the contact finish thickness and plating grade are shared across these three. The 87666-3 carries a thicker 78.0µin (1.98µm) tin finish for applications requiring additional plating margin, while maintaining the same 22-26 AWG wire range.
