The tin-plated solder tails (78.7 µin) are compatible with standard lead-free soldering processes. ## Through-Hole Mounting — Board Retention The 0.526\" (13.35 mm) overall contact length includes a 0.305\" (7.75 mm) mating length, which accommodates standard 0.100\" pitch receptacles. ## Wide Temperature Range — Industrial Duty The thermoplastic housing (UL94 V-0) and phosphor bronze contacts handle thermal cycling without degradation. The black insulation color provides visual contrast for inspection. ## Peer Comparison: 10-Position vs 4-Position Both share the 0.100\" pitch, dual-row layout, 3 A rating, 30.0 µin gold mating finish, and through-hole termination. The 10-position variant is the choice for a 10-circuit BOM; the 4-position 77313-122-04LF is the fit for a 4-circuit line. The 77313-101-04LF is another 4-position sibling with a slightly shorter overall contact length (0.425\" vs 0.526\") — verify the mating length requirement before substituting.","metaTitle":"77313-122-04LF Amphenol ICC (FCI) BERGSTIK® Header 4 Pos","metaDescription":"77313-122-04LF Amphenol ICC (FCI) BERGSTIK® unshrouded header, 4 positions, 0.100\" (2.54 mm) pitch, through hole, 3 A per contact, 30 µin gold 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":"4","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":"0.526\\\" (13.35mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.305\\\" (7.75mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.40000","currency":"USD"},{"qty":10,"price":"$0.34200","currency":"USD"},{"qty":100,"price":"$0.26630","currency":"USD"},{"qty":500,"price":"$0.22822","currency":"USD"},{"qty":1000,"price":"$0.19018","currency":"USD"},{"qty":5000,"price":"$0.16301","currency":"USD"},{"qty":10000,"price":"$0.15215","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/15efa251dc12bbd88801820e63936d0f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the pinout and pitch of 77313-122-04LF?","answer":"All positions are loaded.
