The through-hole tails are 0.119\" (3.02 mm) long, which clears most 1.6 mm PCBs with room for a wave-solder fillet. Use a mating housing with a polarisation key or a strain-relief clip if the assembly will see frequent reconnects. ## Current and Contact Grade That thickness is the industry standard for moderate-cycle applications — think 100–500 mates over the product life. In a field-service connector that gets cycled quarterly, that is decades of reliable contact. ## Sibling Comparison: 77311-819-03LF The 77311-819-03LF is the same BERGSTIK® unshrouded header, same pitch, same plating, same current rating — but with 3 circuits instead of 2. No other parametric difference between the two.","metaTitle":"77311-819-02LF BERGSTIK® Header, 2 Pos, 2.54 mm Pitch","metaDescription":"Amphenol ICC (FCI) 77311-819-02LF: BERGSTIK® unshrouded header, 2 circuits, 0.100\" pitch, 3 A per contact, gold mating finish, through-hole.","metaKeywords":null},"attributes":{"series":"BERGSTIK®","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Style":"Board to Board","Series":"BERGSTIK®","Package":"Bag","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Ingress Protection":"-","Base Product Number":"77311","Insulation Material":"Thermoplastic","Number of Positions":"2","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.119\\\" (3.02mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~125°C","Mated Stacking Heights":"-","Overall Contact Length":"0.724\\\" (18.40mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.505\\\" (12.83mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.48000","currency":"USD"},{"qty":10,"price":"$0.41200","currency":"USD"},{"qty":100,"price":"$0.32020","currency":"USD"},{"qty":500,"price":"$0.27446","currency":"USD"},{"qty":1000,"price":"$0.22871","currency":"USD"},{"qty":5000,"price":"$0.19604","currency":"USD"},{"qty":10000,"price":"$0.18297","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b7619af15a6f914d234facab530ef078.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/77311-819-02LF","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/amphenol/77311-819-02LF when reusing this data.
