The connector supports two mated stacking heights — 11 mm and 12 mm — giving the board designer a choice of z-height budget for the mezzanine gap. A built-in board guide aids alignment during blind-mate assembly, which is common in PMC module installations where the receptacle is soldered to the carrier board and the plug is on the mezzanine card. ## Stacking Height and Board Fit The 5120603-1 is specified for two mated stacking heights: 11 mm and 12 mm. That means the same receptacle, paired with the correct plug height, can be used in either a tighter or a taller mezzanine gap. The 0.290\" (7.37 mm) height above board of the receptacle itself is the fixed dimension; the plug half (not included) determines which of the two stack heights you get. For a PMC module the 11 mm stack is the standard, but the 12 mm option provides extra clearance for taller components on the mezzanine card. The plug order code varies by the desired stacking height and position count — for 64 positions, the mating plug is typically from the same FH series (e.g., 1-120532-2 is an 84-position plug and does not mate directly due to position count mismatch). The receptacle accepts the plug's center strip contacts with outer shroud alignment; the board guide on the receptacle helps center the plug during engagement. ## Comparison with 1-120532-2 The 1-120532-2 is a plug (center strip contacts) from the same Free Height FH series, but at 84 positions it does not mate with the 64-position 5120603-1 receptacle. The pitch is the same 0.039\" (1.00 mm), and both are dual-row surface-mount, but the 1-120532-2 has a lower height above board (0.250\" vs 0.290\") and a thicker gold plating (50.0 µ\" vs 30.0 µ\"). For a 64-position mezzanine application, the correct mating plug is a 64-position FH plug — not the 84-position variant.","metaTitle":"TE 5120603-1 Free Height FH Receptacle, 64 Pos","metaDescription":"TE 5120603-1 Free Height FH receptacle, 64 positions, 1.00 mm pitch, SMT, gold 30.0 µin.
