It uses a 0.039\" (1.00mm) pitch on two rows of center strip contacts, which keeps the board footprint tight for a 64-bit parallel bus. The connector is surface-mount only, with a board guide built into the housing to align the plug during card insertion — without that guide, the fine-pitch contacts can skew on mate. The plug accepts mated stacking heights of 10mm, 12mm, 13mm, or 15mm, which means one board layout can serve different card-to-carrier spacing by swapping the mating receptacle height alone. ## Stack Height Selection and Board Spacing The 5146888-1 plug itself has a height above board of 0.329\" (8.35mm). When mated with the corresponding Free Height receptacle, the total stack height falls into one of four options: 10mm, 12mm, 13mm, or 15mm. The actual height depends on the receptacle's own board standoff, not the plug. The plug is the same across all four — only the receptacle changes. ## Comparing the 64-Position 5146888-1 with the 84-Position 1-120532-2 The 1-120532-2 is the 84-position sibling in the same Free Height IEEE 1386 family, sharing the same 1.00mm pitch, SMT mounting, and gold-plated center strip contacts. The two parts differ in three ways that matter for selection. First, position count: 84 circuits vs 64, so the 1-120532-2 fits a wider PMC bus or more I/O lines. Third, height above board: 0.250\" (6.35mm) on the 84-position part versus 0.329\" (8.35mm) on the 64-position, which changes the available stack height range. Both are active parts; neither is a drop-in replacement for the other because the footprint and board keep-out zones differ with the position count. For BOM planning, the 64-position count and 1.00mm pitch are the critical fit checks; the mating half is the corresponding Free Height receptacle in the desired stack height.","metaTitle":"TE Connectivity 5146888-1 Free Height Plug, 64 Pos","metaDescription":"TE Connectivity 5146888-1 Free Height (FH) IEEE 1386 PMC plug, 64 positions, 0.039\" (1.00mm) pitch, 30.0µin gold contacts, SMT.","metaKeywords":null},"attributes":{"series":"Free Height (FH) IEEE 1386, PMC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Board-to-Board Connectors","Mezzanine & Stacking Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Pitch":"0.039\\\" (1.00mm)","Series":"Free Height (FH) IEEE 1386, PMC","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Board Guide","Mounting Type":"Surface Mount","Connector Type":"Plug, Center Strip Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Active","lifecycle_stage":"unknown","Height Above Board":"0.329\\\" (8.35mm)","Base Product Number":"5146888","Number of Positions":"64","Mated Stacking Heights":"10mm, 12mm, 13mm, 15mm","Contact Finish Thickness":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.6100","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.61000","currency":"USD"},{"qty":10,"price":"$7.50000","currency":"USD"},{"qty":25,"price":"$7.30280","currency":"USD"},{"qty":50,"price":"$7.10520","currency":"USD"},{"qty":100,"price":"$6.67100","currency":"USD"},{"qty":400,"price":"$5.57050","currency":"USD"},{"qty":800,"price":"$5.23894","currency":"USD"},{"qty":1200,"price":"$4.67525","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What are the mated stacking heights for the 5146888-1?","answer":"The 5146888-1 plug supports mated stacking heights of 10mm, 12mm, 13mm, and 15mm when paired with the corresponding Free Height receptacle.
