All 50 positions are loaded, so there are no unpopulated pins to manage in the layout. The solder tails measure 0.105\" (2.67 mm) long, sufficient for standard 0.062\" PCBs with through-hole soldering. ## 30 µinch Gold Mating Surface and Latch Lock Retention The mating contacts carry 30.0 µinch (0.76 µm) of gold over nickel on the pin surface. The contact base is phosphor bronze alloy, which provides good spring properties and corrosion resistance. A keying slot and mounting flange are included — the keying prevents mis-mating with non-keyed receptacles, and the flange provides a mechanical anchor point for panel-mount or strain-relief brackets.","metaTitle":"66429-091 Amphenol ICC (FCI) Quickie™ Header, 50 Pos","metaDescription":"66429-091 Amphenol ICC (FCI) Quickie™ series header, 50 positions, 0.100\" pitch, right-angle through-hole, 30 µinch gold plating, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Cable/Wire","Series":"Quickie™","Package":"Tray","Features":"Keying Slot, Mounting Flange","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Latch Lock/Eject Hooks","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze Alloy","Insulation Color":"Blue","Insulation Height":"0.681\\\" (17.30mm)","Ingress Protection":"-","Base Product Number":"66429","Insulation Material":"Polybutylene Terephthalate (PBT), Glass Filled","Number of Positions":"50","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"-","Contact Length - Post":"0.105\\\" (2.67mm)","Current Rating (Amps)":"-","Operating Temperature":"-","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.230\\\" (5.84mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.0877","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a689d00f83a1a7c2132efa6acebe5f33.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/66429-091/alternatives.json"},"ai":{"faq":[{"question":"What is the pin count and pitch of 66429-091?","answer":"All 50 positions are loaded."},{"question":"Does 66429-091 have a keying slot and mounting flange?","answer":"Yes, the 66429-091 includes a keying slot and mounting flange.
