If your enclosure has a tight z-height budget, that number sets the clearance for components under the top board. Rated 1 A DC per contact, this is a signal-density interconnect, not a power rail. ## Shrouded Housing and SMT Termination Surface-mount termination with tin-plated solder tails (100 µinch) — the tails are designed for reflow assembly. It ships in tube packaging.","metaTitle":"73547-125LF Amphenol ICC (FCI) Rib-Cage III 50-Position","metaDescription":"73547-125LF — 50-position, 1.27 mm pitch, shrouded SMT header. 30 µinch gold mating contacts, 1 A DC rating, 9.93 mm stack height.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"73547-125LF","Series":"Rib-Cage™ III","Package":"Tube","Features":"Board Guide","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.050\\\" (1.27mm)","Insulation Color":"Natural","Insulation Height":"0.364\\\" (9.25mm)","Base Product Number":"73547","Insulation Material":"Thermoplastic, Glass Filled","Number of Positions":"50","Row Spacing - Mating":"0.050\\\" (1.27mm)","Contact Finish - Post":"Tin","Current Rating (Amps)":"1A (DC)","Operating Temperature":"-55°C~130°C","Mated Stacking Heights":"9.93mm","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.130\\\" (3.30mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5545","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/731b3cee66723ea6cf4ca02249714427.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the mating connector for 73547-125LF?","answer":"The 73547-125LF is a male pin header that mates with a Rib-Cage III receptacle (female socket) of the same 50-position, dual-row, 1.27 mm pitch layout.
