The 6.45mm standoff on this header leaves room for the mating receptacle's profile to hit either target. That dual-height capability gives the layout engineer flexibility: the same header can serve a low-profile stack (7mm) or a taller one (12mm) by swapping only the receptacle half, without requalifying the footprint. ## Gold-plated contacts in a two-row array The two-row arrangement keeps the connector body narrow, which helps route traces out of the inner row on the PCB without excessive via fanout. ## Board guide and SMT mounting for automated assembly Surface-mount termination suits reflow soldering on standard PCB processes; the tube packaging (not tape-and-reel on this suffix) means it feeds through tube feeders or can be hand-placed for prototype runs. ## Height variants in the same 100-position footprint The FX8C series offers three height variants at 100 positions, all sharing the same 0.60mm pitch and gold-plated two-row layout. The FX8C-100P-SV2(91) at 0.254\" (6.45mm) sits between the shorter FX8C-100P-SV(91) at 0.175\" (4.45mm) and the FX8C-100P-SV1(91) at 0.214\" (5.45mm). The choice between them is driven purely by the mated stack height target — 7mm or 12mm for the SV2, versus shorter stack heights for the SV and SV1. All three use the same PCB footprint, so swapping heights mid-design requires no board layout change. No official successor or replacement has been issued — this is the current production version. The outer shroud contacts on the header engage with the receptacle's inner contact beams, providing a shrouded interface that resists dust ingress and prevents stubbing during blind mating. Typical deployment is in parallel PCB stacks inside telecom switches, data routers, or industrial controllers where signal density and board spacing are both constrained.","metaTitle":"Hirose FX8C-100P-SV2(91) FunctionMax Header, 100 Pos","metaDescription":"Hirose FX8C-100P-SV2(91) FunctionMax™ FX8C header, 100 positions, 0.60mm pitch, 6.45mm height, SMT, gold plating, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"FunctionMax™ FX8C","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Board-to-Board Connectors","Mezzanine & Stacking Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Pitch":"0.024\\\" (0.60mm)","Series":"FunctionMax™ FX8C","Package":"Tube","Features":"Board Guide","Mounting Type":"Surface Mount","Connector Type":"Header, Outer Shroud Contacts","Contact Finish":"Gold","Number of Rows":"2","Product Status":"Active","lifecycle_stage":"unknown","Height Above Board":"0.254\\\" (6.45mm)","Base Product Number":"FX8","Number of Positions":"100","Mated Stacking Heights":"7mm, 12mm","Contact Finish Thickness":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2500","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.25000","currency":"USD"},{"qty":10,"price":"$4.76900","currency":"USD"},{"qty":25,"price":"$4.51680","currency":"USD"},{"qty":50,"price":"$4.41160","currency":"USD"},{"qty":100,"price":"$4.20160","currency":"USD"},{"qty":250,"price":"$3.67640","currency":"USD"},{"qty":500,"price":"$3.57136","currency":"USD"},{"qty":1000,"price":"$3.04616","currency":"USD"},{"qty":2500,"price":"$2.83608","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a5a70ed028094c8838edeb48b4262d48.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the stacking heights for FX8C-100P-SV2(91)?","answer":"The FX8C-100P-SV2(91) supports mated stacking heights of 7mm and 12mm, determined by the combined height of this header and its mating receptacle."},{"question":"What is the pitch of FX8C-100P-SV2(91)?","answer":"The pitch is 0.024\" (0.60mm), which places it in the fine-pitch mezzanine connector class for dense board-to-board interconnects."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/hirose-electric-co-ltd/FX8C-100P-SV2~191~2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/hirose-electric-co-ltd/FX8C-100P-SV2~191~2 when reusing this data.
