The mated stacking height is 3mm, with the connector standing 0.087\" (2.20mm) above the board — a tight z-height that suits compact portable electronics, handheld instruments, and any design where board spacing is at a premium. ## 3mm Stack — What That Means for Board Layout The 3mm mated stack height is fixed by the connector body — the DF12A(3.0) variant is specifically tooled for that gap, so the mating header must also carry the (3.0) suffix to achieve the correct board spacing. The 0.087\" (2.20mm) above-board height leaves about 0.8mm clearance under the connector body for passives or routing on the top layer. ## Obsolete — Sourcing Path for This BOM Line No direct replacement order code is listed in the lifecycle record, so the sourcing route is through surplus or broker channels.","metaTitle":"Hirose DF12A(3.0)-40DS-0.5V(80) 40-Position Receptacle","metaDescription":"Hirose DF12A(3.0)-40DS-0.5V(80) 40-position receptacle, 0.50mm pitch, 3mm stacking height.
