It uses a 1.00 mm pitch dual-row layout with center strip contacts, surface-mounted to the board. The connector supports multiple mated stacking heights — 10 mm, 12 mm, 13 mm, and 15 mm — giving the board layout engineer flexibility to set the card-to-card spacing within the enclosure. The 0.329\" (8.35 mm) height above board is the plug's own profile before stacking; the actual board-to-board gap is determined by the mating receptacle's height. ## RoHS Status Note The 146888-1 is listed as RoHS non-compliant. If your assembly requires full RoHS exemption or a compliant alternative, verify the bill of materials against the exemption scope before committing the design. ## Position Count vs. the 84-Position Sibling The closest functional peer in the same Free Height (FH) series is the 1-120532-2, which shares the same 1.00 mm pitch and SMT plug form factor but carries 84 positions (20 more than the 146888-1) and a shorter 6.35 mm height above board. The 1-120532-2 also uses a thicker 50.0 µin gold contact finish, which supports a higher mating cycle count in high-reliability applications. The choice between the two comes down to the position count your BOM requires and the board-to-board stack height budget — the 146888-1 offers four stacking heights (10–15 mm) against the 1-120532-2's single 6.35 mm height.","metaTitle":"TE Connectivity 146888-1 Free Height (FH) Plug, 64 Pos","metaDescription":"TE 146888-1 Free Height (FH) IEEE 1386 PMC plug, 64 positions, 1.00 mm pitch, gold 30.0 µin, SMT.
