The 0.230\" (5.84 mm) mating pin length mates with standard 2.54 mm pitch female socket strips — the same pitch used across the BERGSTIK and compatible IDC families. Pin-one is marked by the chamfered edge of the black thermoplastic housing. ## Mating Finish and Cycle Life At this plating grade, expect 50–100 mating cycles before contact resistance begins to rise — fine for bench-test or field-service connectors that see occasional disconnect, not daily hot-plug. No gold on the post; the tin surface is compatible with both leaded and lead-free solder processes. The part is RoHS compliant and carries UL94 V-0 flammability rating on the thermoplastic housing.","metaTitle":"77313-818-36LF BERGSTIK® Header – 36 Pos, 2.54mm Pitch","metaDescription":"Amphenol ICC (FCI) BERGSTIK® unshrouded header, 36 positions, 0.100\" pitch, 3 A per contact, gold/GXT mating finish.","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 or Cable","Series":"BERGSTIK®","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","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":"77313","Insulation Material":"Thermoplastic","Number of Positions":"36","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A per Contact","Operating Temperature":"-65°C~130°C","Mated Stacking Heights":"-","Overall Contact Length":"0.450\\\" (11.43mm)","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":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6200","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.62000","currency":"USD"},{"qty":10,"price":"$1.41000","currency":"USD"},{"qty":100,"price":"$1.26030","currency":"USD"},{"qty":500,"price":"$1.05024","currency":"USD"},{"qty":1000,"price":"$0.90021","currency":"USD"},{"qty":5000,"price":"$0.79819","currency":"USD"},{"qty":10000,"price":"$0.78019","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/15efa251dc12bbd88801820e63936d0f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 77313-818-36LF compatible with standard 2.54 mm female headers?","answer":"Yes.
