The 0.079\" (2.00mm) height above board and 2.5mm mated stacking height define the z-axis clearance between the two PCBs; that 2.5mm gap is the dimension you design the enclosure standoffs around. The gold-on-gold interface keeps contact resistance stable through the first several mates, which matters for signal integrity in a high-density differential pair layout. ## Surface-Mount Assembly and Packaging Surface-mount termination suits reflow soldering on standard SMT lines. The 0.50mm pitch means the PCB footprint needs tight solder paste registration — the pad layout in the product drawing is the one to follow, not a generic 0.50mm pattern.","metaTitle":"Molex 0541020304 SlimStack 54102","metaDescription":"Molex 0541020304 SlimStack 54102 receptacle, 30 positions, 0.50mm pitch, 2 rows, gold 10.0µin contacts. 2.5mm mated stack height.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Board-to-Board Connectors"],"specifications":{"Pitch":"0.020\\\" (0.50mm)","Series":"SlimStack 54102","Features":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Active","Manufacturer":"Molex","Mounting Type":"Surface Mount","Connector Type":"Receptacle, Center Strip Contacts","Contact Finish":"Gold","Number of Rows":"2","lifecycle_stage":"unknown","Height Above Board":"0.079\\\" (2.00mm)","Base Product Number":"054102","Number of Positions":"30","Mated Stacking Heights":"2.5mm","Contact Finish Thickness":"10.0µin (0.25µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c5a3fd1dc1ec80c6f2b4be03bc391d99.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy Molex 0541020304?","answer":"Submit a quote request for current pricing and availability — stock position and lead time are confirmed at quote time, not listed on the page."},{"question":"What is the mating height for 0541020304?","answer":"The mated stacking height is 2.5mm. The connector stands 0.079\" (2.00mm) above the board surface before mating, so the total z-height between the two PCBs in the mated assembly is 2.5mm."},{"question":"Is 0541020304 RoHS compliant?","answer":"The part is listed as RoHS compliant — no RoHS exemption or lead-content note appears on the record. The gold plating (10.0µin) and the housing material in the SlimStack 54102 series are specified for lead-free reflow profiles."},{"question":"What is the pitch of 0541020304?","answer":"The contact pitch is 0.020\" (0.50mm). That 0.50mm center-to-center spacing is the dimension that drives the PCB footprint trace routing and via placement between the two rows."},{"question":"What is the contact finish thickness on 0541020304?","answer":"The contact finish is gold at 10.0µin (0.25µm) thickness. That plating grade supports moderate mating cycles — enough for board assembly and rework, but not intended for repeated field disconnect."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/0541020304","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/molex/0541020304 when reusing this data.
